Further aspects and areas of applicability will become apparent from the description provided herein. It should be understood that various aspects of this disclosure may be implemented individually or in combination with one or more other aspects. It should also be understood that the description and specific examples herein are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Example embodiments will now be described more fully with reference to the accompanying drawings.
There is an open characteristic of a web page, and if a system function of an intelligent device may be invoked by any web page with any restriction, then the performance and the security of the intelligent device may be degraded. Thus invoking of a system function of the intelligent device needs to be constrained and supervised, and there are generally the following two supervision schemes at present:
Firstly a list of Uniform Resource Locators (URLs) is hardened in the intelligent device, and before a system function is allowed to be invoked by a web page, the intelligent device determines whether a URL of the web page belongs to the list of URLs, and if not, then the system function is prohibited from being invoked by the web page. In this scheme, the list of URLs which has been firmed in the intelligent device before the intelligent device leave the factory may not be adjusted flexibly.
Secondly a web page is packaged into a web application with a configuration file including indicators of system functions to be invoked, and the intelligent device running the web application extracts the indicators and generates a privilege tree of the web application from the indicators so that each branch of the privilege tree represents particular one of the system functions, and when a system function needs to be invoked by the web application, the intelligent device determines whether there is such a privilege in the privilege tree that corresponds to the system function, and if so, then the system function is allowed to be invoked; otherwise, the system function is prohibited from being invoked. In this scheme, the web page needs to be packaged into the web application under a specific rule, and the configuration file needs to be set for each web page, which may contradict the development trend of the web applications becoming light-weighted, and the diversity of states in which they appear.
In order to address the technical problem above, some embodiments of the disclosure provide at least one method and device in an intelligent device for controlling a web page to invoke a system function so as to control flexibly the web page to invoke the system function without setting a configuration file for the web page. In these embodiments, a browser in the intelligent device parses a web page for an authorization code, and a privilege code of a system function requested to be invoked, in the web page, obtains a system function invoking privilege of the web page according to the authorization code, determines that the privilege code of the system function requested to be invoked by the web page belongs to the list of privilege codes in the system function invoking privilege, and invokes the system function requested to be invoked by the web page through an interface function of the corresponding system function, so that the browser may determine the system function invoking privilege of the web page simply by obtaining the authorization code of the web page without setting a configuration file for the web page or packaging the web page, and may control flexibly the web page to invoke the system function, by adjusting the authorization code or the system function invoking privilege corresponding to the authorization code.
In some embodiments of the disclosure, as illustrated in
Operation 101: A browser in an intelligent device parses a web page for an authorization code in the web page, and a privilege code of a system function requested to be invoked.
In some embodiments of the disclosure, a privilege code is preset for each system function in the intelligent device, and the privilege code of the system function may identify uniquely a system function invoking privilege. Different system functions correspond to different privilege codes. In some embodiments, each system function corresponds to a JS object, that is, one privilege code corresponds to one JS object. The intelligent device takes the authorization code of the web page as an input parameter to invoke the JS object corresponding to the system function so as to create a JS object instance, which functions as an interface function, and to invoke the system function through the JS object instance.
Here the web page may be run online or offline.
In some embodiment of the disclosure, the authorization code of the web page may be formed as follows:
A cloud server obtains information about the web page, and information about the system function of the intelligent device requested by a developer of the web page to be invoked, and generates authorization information of the web page, and the authorization code of the web page; and the cloud server stores the authorization code of the web page, and the authorization information of the web page, and transmits the authorization code to the web page.
In some embodiments, the information about the web page includes at least an identifier of the web page. The authorization information of the web page may include at least the information about the web page, and the system function invoking privilege and additionally a generation time, a validity period of time, and a scrambler, of the authorization code, and the system function invoking privilege includes a list of privilege codes of system functions allowed to be used by the web page.
Operation 102: The browser obtains a system function invoking privilege corresponding to the web page according to the obtained authorization code, where the system function invoking privilege includes a list of privilege codes of system functions allowed to be used by the web page.
Optionally if the browser in the intelligent device may access the cloud server, then the authorization code may include only the identifier of the web page so that the browser in the intelligent device obtains authorization information of the web page from the cloud server according to the authorization code.
In this embodiment, the browser in the intelligent device may determine whether there is a system function invoking privilege corresponding to the authorization code, according to a correspondence relationship in a memory of the intelligent device, between the authorization code and the system function invoking privilege, and if so, then the browser obtains the system function invoking privilege corresponding to the authorization code, and determines the obtained system function invoking privilege as the system function invoking privilege corresponding to the web page; and
If not, then the browser in the intelligent device may transmit the authorization code to the cloud server, and the cloud server may obtain and return to the browser a system function invoking privilege corresponding to the authorization code according to the authorization code, and the browser in the intelligent device may receive the system function invoking privilege returned by the cloud server, determine the received system function invoking privilege as the system function invoking privilege corresponding to the web page, and store a correspondence relationship between the system function invoking privilege of the web page and the identifier of the web page in the memory.
In some embodiments, the authorization code further includes a system function invoking privilege corresponding to the web page in addition to the identifier of the web page.
In some embodiment of the disclosure, if the browser in the intelligent device has not received the system function invoking privilege of the web page returned by the cloud server in a preset length of time after transmitting the authorization code of the web page to the cloud server, then the browser may parse the authorization code to obtain the system function invoking privilege carried in the authorization code, and determine the obtained system function invoking privilege as the system function invoking privilege corresponding to the web page.
in some embodiments, the authorization code further includes information about the web page in addition to the identifier of the web page.
In some embodiment of the disclosure, if the cloud server determines the information about the web page carried in the authorization code of the web page is the same as locally stored information about the web page corresponding to the identifier of the web page, then the cloud server may return the system function invoking privilege of the web page to the intelligent device.
If the cloud server determines the information about the web page carried in the authorization code of the web page is not the same as the locally stored information about the web page corresponding to the identifier of the web page, then the cloud server returns an error to the intelligent device; and if the browser in the intelligent device receives the error returned by the cloud server, then the browser may reject the web page for invoking the requested system function.
Operation 103: If the browser determines that the privilege code of the system function requested to be invoked by the web page belongs to the list of privilege codes in the system function invoking privilege, then the browser invokes the system function requested to be invoked by the web page through an interface function of the corresponding system function to support running of the web page; otherwise, the browser prohibits invoking of the interface function of the system function requested to be invoked by the web page.
in some embodiments, in the intelligent device, a privilege code may be set for each system function allowed to be invoked by the web page so that different system functions may correspond to different privilege codes.
In some embodiment of the disclosure, the intelligent device may categorize the system functions allowed to be invoked by the web page, and set a first privilege code for each category so that different first privilege codes may be set for different categories, and set a second privilege code for each system function in each category so that different second privilege codes may be set for different system functions of the same category.
Here if the privilege code, obtained by the browser in the intelligent device, of the system function requested to be invoked by the web page is a first privilege code, then the browser invoke the interface function of the system function upon determining that the first privilege code is included among the system function privileges of the web page; and if the privilege code, obtained by the browser in the intelligent device, of the system function requested to be invoked by the web page is a second privilege code, then the browser invoke the interface function of the system function upon determining that the second privilege code, or the first privilege code, to which the second privilege is subordinated, is included among the system function privileges of the web page.
In some embodiment of the disclosure, the interface function of the system function may be a JS object or a JS method.
A process of controlling a web page to invoke a system function will be described below in an embodiment thereof with reference to
Operation 201: A JS object is preset for each system function in an intelligent device, and a browser in the intelligent device obtains an authorization code of the web page including at least the identifier of the web page, takes the authorization code as an input parameter of the JS object corresponding to the system function requested to be invoked, and creates an JS object instance corresponding to an interface function of the system function requested to be invoked by the web page, and the authorization code at least includes the identifier of the web page;
Operation 202: The browser in the intelligent device searches a memory according to the authorization code of the web page for a system function invoking privilege corresponding to the authorization code, and if it is found, then the process proceeds to the operation 203; otherwise, the process proceeds to the operation 204;
Operation 203: The browser in the intelligent device obtains the system function invoking privilege of the web page from the memory, and the process proceeds to the operation 207;

Operation 205: The browser in the intelligent device determines whether the information returned by the cloud server includes a system function invoking privilege of the web page, and if so, then the process proceeds to the operation 207; otherwise, the process proceeds to the operation 209;
Operation 206: The browser in the intelligent device parses the authorization code of the web page for a system function invoking privilege in the authorization code, and the process proceeds to the operation 207;
Operation 207: The browser in the intelligent device determines whether the requested system information is allowed by the obtained system function invoking privilege to be invoked by the web page, and if so, then the process proceeds to the operation 208; otherwise, the process proceeds to the operation 209;
Operation 208: The browser in the intelligent device executes a particular logic of the JS object instance; and
Operation 209: The browser in the intelligent device prohibits the requested system function from being invoked by the web page, and prohibits a particular logic of the JS object instance from being executed.
