DETAILED DESCRIPTION OF THE INVENTION

To better clarify the purposes, technical solutions and advantages of the embodiments of the present invention, the technical solutions of the embodiments of the invention will be clearly and completely described. Obviously, the embodiments in the following description are merely illustrative ones, and are not all possible ones of the invention. All other embodiments obtained by those ordinarily skilled in the art without creative labor should also fall within the protection scope of the invention.

A resource access channel exclusive to the resource access request is established according to the exclusive access mediator instance temporarily generated by the resource access request, and after the resource access session is finished, the access mediator instance is deleted. That is to say, the system dynamically selects and configures or directly dynamically selects the access mediator substance for accessing the target resource according to the target resource information in the resource access request or the user information and the target resource information in the resource access request. Before the access mediator substance is started and configured (corresponding to the condition where the access mediator substance needs to be configured) or before the access mediator substance (corresponding to the condition where the access mediator substance does not need to be additionally configured, for example, an access mediator instance is merely used for accessing a certain specific website, and after the access mediator instance is started, it is not needed to configure the access mediator instance, and the aforementioned specific website may be directly accessed by the access mediator instance) is started, the access channel will not be established between the user terminal and the target resource. After the access mediator instance is started and configured (similarly, corresponding to a condition needed to configure the access mediator substance) or the access mediator instance is started (similarly, corresponding to a condition not needed to configure the access mediator substance additionally), the resource access channel exclusive to the resource access request is established, and the resource access request arrives at the target resource by means of the access mediator instance. After the resource access request session is finished, the access mediator instance is deleted. When a next resource access request is initiated, the access channel will not be established between the user terminal and the target resource, and the resource access request may not be sent to the target resource, so that the user experience is guaranteed and the system security is improved.

For the sake of a good understanding, the relationship between the access request and the access request information is defined here as follows: the access request is to add information for network transmission, such as a network communication transmission format and session information, based on the access request information.

As shown in FIG. 1 and FIG. 2, this embodiment provides a system for processing network resource access requests, comprising:

• • a request receiver 101, configured for receiving a resource access request, acquiring resource access request information and sending the acquired resource access request information to a request processor 103. The request receiver 101 not only receives the resource access request directly sent by the user via the user terminal, but also receives the resource access request initiated by the user terminal and transferred by a network proxy service.

The request processor 103, on the one hand, is configured for extracting the user information and the target resource information from the received resource access request information and requiring the access mediator manager 105 to establish the corresponding access mediator instance 107-N according to the user information and the target resource information (it may comprise at least two different conditions: one condition is as follows: after the access mediator instance is generated, in a resource access process, a default configuration of the access mediator instance is used without configuring the access mediator instance additionally; for example, an access mediator instance is merely used for accessing a certain specific website, and after the access mediator instance is started, it is not needed to configure the access mediator instance, and the aforementioned specific website may be directly accessed by the access mediator instance. The other condition is as follows: after the access mediator instance is generated, it is needed to configure the access mediator instance correspondingly to realize resource access, specifically illustrated hereinafter). On the other hand, it is configured to initiate access correspondingly to the target resource via the access mediator instance 107-N according to the resource access request information after the access mediator instance 107-N is established. Functions of the access mediator instance 107-N are similar to those of an access gateway which may perform processing including address conversion, protocol conversion, identity authentication and the like. The user information comprises at least one of information such as a user name, a user terminal type, a user department and a user group. The target resource information comprises at least one of information such as a resource identifier, a resource type (a webpage, a network document, a network application and the like) and a network address.

The access mediator manager 105 is configured for selecting the corresponding access mediator template according to the received information (such as a request from the request processor 103), generating the corresponding access mediator instance 107-N according to the access mediator template (in this embodiment, the relationship between the access mediator template and the access mediator instance is similar to the relationship between a Docker mirror image in a Docker application container engine and a Docker container), and starting and configuring the access mediator instance or starting the access mediator instance without extra configuration.

In an optional scope of those skilled in the art, selecting the corresponding access mediator template according to the received information may further be finished by the request processor 103. In this case, the request processor 103 is configured for extracting the user information and the target resource information from the received resource access request information, selecting the corresponding access mediator template according to the user information and the target resource information and requiring the access mediator manager 105 to generate and configure the corresponding access mediator instance 107-N according to the access mediator template selected by the request processor 103. The access mediator manager 105 is configured to generate the corresponding access mediator instance 107-N according to the access mediator template, and start and configure the access mediator instance or start the access mediator instance without extra configuration.

For the sake of a good understanding, selecting the corresponding access mediator template is illustrated below:

For example, the user accesses the access mediator instance needed by a website via a mobile phone, which is different from accessing the access mediator instance needed by a document (the document may be a word document, a PDF document or the like) on a network via a PC (Personal Computer). When the access mediator template is selected, it is needed to select the corresponding access mediator template according to the terminal type (one of the user information) to guarantee terminal adaptation, and it is also needed to select the corresponding access mediator template according to the target resource type (one of the target resource information) to guarantee that the access mediator template is adaptive to the resource type, so as to realize normal presentation of the resource information. That is, the user accesses different resources (such as a website, a document on the network, an application on the network and the like) via different user terminals (such as a mobile phone, a tablet personal computer, a PC and the like) with different access mediator instances, so that it is needed to select the corresponding access mediator template according to the user information and the target resource information. In the optional scope of those skilled in the art, when the access mediator template is selected, the user information is not limited to the terminal type, and the target resource information is further not limited to the resource type.

For the sake of a good understanding, configuring the access mediator instance is illustrated below:

When the resource access request is a website on the access network, an implementation for configuring the access mediator instance is to configure a web address of the website to the access mediator instance by the access mediator manager 105.

When the resource access request is a website on the access network and needs to support the user to download a document from the website or upload the document to the website, an implementation for configuring the access mediator instance is to configure a web address of the website and a network disc menu of the user to the access mediator instance by the access mediator manager 105.

When the resource access request is an application on the access network and needs to support the user to process certain data by using the application, an implementation for configuring the access mediator instance is to configure a web address of the application and data needed to be processed to the access mediator instance by the access mediator manager 105. The data may be merely data from the user or may comprise the resource data from the network or the data associated with the target resource. For example, when the user needs to process a picture on the network disc by means of a photoshop server on the network, an implementation for configuring the access mediator instance is to configure an address and an access mode (such as a user name, a password or the like), an address of the picture on the network disc and an access mode (such as a user name, a password or the like) to the access mediator instance by the access mediator manager 105.

When the network resource is accessed by using the system for processing network resource access requests in this embodiment, before the access mediator substance is started and configured (corresponding to the condition where the access mediator substance needs to be configured) or before the access mediator substance (corresponding to the condition where the access mediator substance does not need to be additionally configured) is started, the access channel will not be established between the user terminal and the target resource. After the access mediator instance is started and configured (similarly, corresponding to the condition where the access mediator substance needs to be configured) or the access mediator instance is started (similarly, corresponding to the condition where the access mediator substance does not need to be additionally configured), the resource access channel exclusive to the resource access request is established, and the resource access request arrives at the target resource by means of the access mediator instance. Compared with the solution that an access channel always exists between the user terminal and the target resource in the prior art, the network security may be improved greatly. Meanwhile, by accessing the target resource by using the exclusive access mediator instance, the user terminal is not directly interacted with the target resource, so that the target source is protected against attack threats from the user terminal, data leakage is prevented, and the user terminal is protected against hazards caused by malicious contents from the target resource.

As a preferred implementation of this embodiment, in order to realize a closed loop of the network resource access, the system for processing network resource access requests further comprise:

• • a response processor 109 for receiving a response of the target resource transferred by the access mediator instance and transmitting the response to the response sender 111; and
  • the response sender 111 for sending the response transmitted by the response processor 109 to the user terminal as the response to the resource access request, so that the request and response process of the whole access is finished.

More preferably, the response processor 109 may further be used for processing the received response to obtain information in an image coded format (see Chinese Invention Patent Application No. 202011413791.2 for a specific solution) and sending the information as the response information to the response sender 111.

Preferably, the access mediator manager 105 is further configured to delete the access mediator instance after a resource access session is finished. That is, the exclusive access mediator instance generated according to the resource access request is merely suitable for the resource access session, after the resource access request session is finished, the access mediator instance will be deleted immediately. When a next resource access request is initiated, the access channel will not be established between the user terminal and the target resource, and the resource access request will not be sent to the target resource, thus guaranteeing the system security.

As another preferred implementation of this embodiment,

The request processor 103 is further configured for judging the legality of the resource access request information. Under the circumstance that the resource access request information is legal, the extracted user information and target resource information are sent to the access mediator manager 105.

As shown in FIG. 3, this embodiment provides a method for processing network resource access requests, comprising:

202. A resource access request is received and resource access request information is acquired.

In this embodiment, this step is realized by the request receiver 101 in the system for processing network resource access requests. The resource access request is directly from the user terminal or is transferred from the network proxy service. For example, the user operates the user terminal by operation to require to access a certain website, and the user terminal responds to the operation to generate the corresponding resource access request.

204. User information and target resource information are extracted from the resource access request information, and it is required to establish a corresponding access mediator instance according to the user information and the target resource information.

In this embodiment, this step is realized by the request processor 103 in the system for processing network resource access requests (the request receiver will transfer the resource access request information to the request processor). The user information comprises at least one of information such as a user name, a user terminal type, a user department and a user group. The target resource information comprises at least one of information such as a resource identifier, a resource type (a webpage, a network document, a network application or the like) and a network address.

Specifically, establishing the access mediator instance may comprise at least two different conditions: one condition is as follows: after the access mediator instance is generated, in a resource access process, a default configuration of the access mediator instance is used without configuring the access mediator instance additionally; for example, an access mediator instance is merely used for accessing a certain specific website, and after the access mediator instance is started, it is not needed to configure the access mediator instance, and the aforementioned specific website may be directly accessed by the access mediator instance. The other condition is as follows: after the access mediator instance is generated, it is needed to configure the access mediator instance correspondingly to realize resource access, specifically illustrated hereinafter.

206. The access mediator instance is established.

In this embodiment, this step is realized by the access mediator manager 105 in the system for processing network resource access requests.

Specifically, the access mediator manager 105 selects the corresponding access mediator template according to the received information (such as a request from the request processor 103 to require to establish the access mediator instance), generates the corresponding access mediator instance 107-N according to the access mediator template (in this embodiment, the relationship between the access mediator template and the access mediator instance is similar to the relationship between a Docker mirror image in a Docker application container engine and a Docker container), and starts and configures the access mediator instance or starts the access mediator instance without extra configuration.

In the optional scope of those skilled in the art, establishing the access mediator instance may further comprises: the access mediator manager 105 generates the corresponding access mediator instance 107-N according to the access mediator template determined by the request processor 103, and starts and configures the access mediator instance or start the access mediator instance without extra configuration. In this case, the request processor 103 is configured to extract the user information and the target resource information from the received resource access request information, select the corresponding access mediator template according to the user information and the target resource information and require the access mediator manager 105 to generate and configure the corresponding access mediator instance 107-N according to the access mediator template selected thereby.

For the sake of a good understanding, selecting the corresponding access mediator template is illustrated below:

For example, the user accesses the access mediator instance needed by a website via a mobile phone, which is different from accessing the access mediator instance needed by a document (the document may be a word document, a PDF document or the like) on a network via a PC (Personal Computer). When the access mediator template is selected, it is needed to select the corresponding access mediator template according to the terminal type (one of the user information) to guarantee terminal adaptation, and it is needed to select the corresponding access mediator template according to the target resource type (one of the target resource information) to guarantee that the access mediator template is adaptive to the resource type, so as to realize normal presentation of the resource information. That is, the user accesses different resources (such as a website, a document on the network, an application on the network and the like) via different user terminals (such as a mobile phone, a tablet personal computer, a PC and the like) with different access mediator instances, so that it is needed to select the corresponding access mediator template according to the user information and the target resource information. In the optional scope of those skilled in the art, when the access mediator template is selected, the user information is not limited to the terminal type and the target resource information is further not limited to the resource type.

For the sake of a good understanding, configuring the access mediator instance is illustrated below:

When the resource access request is a website on the access network, an implementation for configuring the access mediator instance is to configure a web address of the website to the access mediator instance by the access mediator manager 105.

When the resource access request is a website on the access network and needs to support the user to download a document from the website or upload the document to the website, an implementation for configuring the access mediator instance is to configure a web address of the website and a network menu of the user to the access mediator instance by the access mediator manager 105.

When the resource access request is an application on the access network and needs to support the user to process certain data by using the application, an implementation for configuring the access mediator instance is to configure a web address of the application and data needed to be processed to the access mediator instance by the access mediator manager 105. The data may be merely data from the user or may comprise the resource data from the network or the data associated with the target resource. For example, when the user needs to process a picture on the network disc by means of a photoshop server on the network, an implementation for configuring the access mediator instance is to configure an address and an access mode (such as a user name, a password or the like), an address of the picture on the network disc and an access mode (such as a user name, a password or the like) to the access mediator instance by the access mediator manager 105.

208. An access is initiated to a target resource correspondingly by using the access mediator instance according to the resource access request information received by the access mediator instance.

Functions of the access mediator instance 107-N are similar to those of an access gateway which may perform processing including address conversion, protocol conversion and the like.

As a preferred implementation of the method for processing network resource access requests of this embodiment, the method further comprises:

• • 210. A response of the target resource is received by using the access mediator instance and the response is transferred to a user terminal.

In this embodiment, the response from the target resource received by the access mediator instance 107-N is transferred to the user terminal via the response processor 109 and the response sender 111 in sequence.

As a more preferred implementation, in this process, the received response may further be processed by the response processor 109 to obtain information in an image coded format (see Chinese Invention Patent Application No. 202011413791.2 for a specific solution), and the information is sent as the response information to the response sender 111.

212. The access mediator instance is deleted.

In this embodiment, this step is realized by the access mediator manager 105 in the system for processing network resource access requests. After the resource access request session is finished, the access mediator manager 105 deletes the access mediator instance immediately, so that when a next resource access request is initiated, the access channel will not be established between the user terminal and the target resource, the resource access request will not be sent to the target resource, thus guaranteeing the system security.

As a preferred implementation scheme of the processing method for the network resource access request of the embodiment, the processing method further comprises:

• • 203. The legality of the resource access request information is judged. If it is legal, Step 204 is executed, and otherwise, the resource access request is abandoned or access prohibiting information is returned.

In this embodiment, this step is realized by the request processor 103 in the system for processing network resource access requests.

Based on this implementation, in the optional scope of those skilled in the art, in order to simplify the processing flow to use the specific user terminal (such as the PC or the mobile phone) to access resources by any user in any condition, the request processor 103 may merely extract the target resource information selectively rather than extracting the user information (the user information is extracted primarily for authority management and terminal adaptation).
