Description

Interface calling method of webpage application program, display equipment and server

Technical Field

The present application relates to the field of computer technologies, and in particular, to a method for calling an interface of a web application, a display device, and a server.

Background

With the development of HTML5 (Hyper Text Markup Language, hypertext markup language 5) and related web page technologies, web apps (web page applications) developed by using HTML5 technology are increasingly accepted and favored by numerous developers. Compared with the traditional NATIVE APP (local application program), the web App has the advantages of lower development cost, simpler upgrading, easier maintenance, no installation and no consumption of user storage space. The web App is essentially a customized web site for mobile phones, televisions, and other display devices.

However, the disadvantages of the web App are also obvious, since the web App can only run in the browser of the display device, and is independent of the display device system, some customized functions, such as obtaining or setting system parameters, operating a database, and reading and writing files, are usually implemented for some application program open part interfaces, and the implementation of these functions requires the web App to call the interfaces in the display device through the browser. Currently, the industry typically makes applications available to access system resources by calling interfaces in JavaScript extensions. But the JavaScript script is automatically embedded into the page of the application program when running, all interfaces and implementation contents thereof are exposed outside, and an application program developer can see definitions of all interfaces and implementation contents thereof, so that local resources of the display device can be abused.

To prevent abuse of the display device's local resources by application developers, and also to secure information for the display device user, web App calls interfaces are often limited. In addition to the conventional approach of using application names to manage the local interface of the display device, the industry also often uses HTTP (Hyper Text Transfer Protocol ) requests in JavaScript to establish a dedicated message channel with a server, which confirms the identity of the application by obtaining the HTTP header information, and then authenticates the identity, allowing or rejecting subsequent requests by the application.

However, the local interface of the display device has high management and maintenance cost and poor expansibility, and needs to be re-adapted each time an application program is newly added or an interface is newly added. The above method using HTTP requests can solve the problem of poor expandability of the local interface of the display device, but the HTTP requests can be forged. If the third-party webpage application program successfully falsifies the HTTP request, thereby obtaining the authorization of the application program and establishing a message channel with the server, the third-party webpage application program can illegally call the local interface of the display device, which has a great threat to the user information security and the resource security of the display device.

Based on the above, the embodiment of the application provides an interface calling method for a web application, a display device and a server, which can separate an authentication flow and an interface calling flow of the web application, advance the authentication flow into a starting flow of the web application, and an interface file generated by the server in the authentication flow is difficult to be modified by the web application in a browser of the display device, so that the interface file is prevented from being forged, the situation that the display device resource is abused due to random calling of the interface by the web application is avoided, and simultaneously, the user information safety and the resource safety of the display device are ensured.

The method provided by the embodiment of the present application is divided into two methods applied to the display device 200 and the server 400 to realize communication between the display device 200 and the server 400.

Fig. 6 is a schematic diagram illustrating an interaction procedure between the display device 200 and the server 400 according to an embodiment of the present application. As shown in fig. 6, after the display device 200 and the server 400 execute the interface calling method of the web application program, an interaction process for completing the interface calling can be performed, and finally, the interface file is generated in the server 400, the interface file is loaded in the display device 200, and the interface file cannot be modified by the web application program, so that the interface file is prevented from being forged, the situation that the resources of the display device 200 are abused due to the fact that the interface is randomly called by the web application program can be avoided, and the user information security and the resource security of the display device 200 are ensured.

The display device 200 provided in the embodiment of the present application may include a controller, where the controller is mainly configured to perform: in response to the web application start instruction sent from the browser, sending related information of the web application and the display device 200 to the server 400; receiving an interface file generated according to the web application and the related information of the display device 200, which is transmitted back from the server 400; and controlling the browser to load the interface file so that the webpage application program calls the target interface. The interface file is used for determining the use authority and parameters of the target interface which the webpage application program needs to call.

The display device 200 in the embodiment of the present application may be a device that may install a browser, such as a smart phone, a smart tv, a computer, or the like, and may run a web application through the browser.

If a user wants to open a certain web application on the display device 200 through a browser, the browser needs to inform the display device 200 that the web application needs to be started, and at this time, a start instruction of the web application needs to be sent to the display device 200, where the start instruction may generally include information such as a name of the web application, a target interface that needs to be called, and so on, so that the display device 200 can learn about the situation of the web application. After receiving the start instruction, the display device 200 needs to send its related information and related information of the web application program to be started to the server 400, so that the server 400 generates a corresponding interface file according to the information.

The relevant information of the display device 200 itself includes a system version of the display device 200 or a model of the display device 200, and taking smart electricity as an example, the system version carried in the product is different or the model of the product is different at each update iteration. Since the interface function or the interface usage right corresponding to each system version is changed or updated, the display device 200 needs to send information such as the system version or the model of the display device itself, which can specify the content of the interface of the display device itself, to the server 400, so that the server 400 can accurately find the interface corresponding to the current system version of the display device 200.

The related information of the web application program comprises interface requirement information of the web application program, namely which target interface or interfaces the web application program needs to call, and the like. The display device 200 transmits the related information of itself and simultaneously transmits the interface requirement information of the web application together, so that the server 400 can accurately determine the target interface required to be invoked by the web application from the interfaces corresponding to the target system version of the display device 200.

As described above, in the case where the related information of the display apparatus 200 itself includes a system version of the display apparatus 200 or a model of the display apparatus 200, and the related information of the web application includes interface requirement information of the web application, in some embodiments, the controller in the display apparatus 200 is further configured to perform: acquiring system version information of the display device 200 and interface requirement information of a webpage application program to be started currently; the system version information and the interface requirement information are transmitted to the server 400. The interface requirement information is used for indicating information of a target interface which needs to be called by the webpage application program.

In general, after receiving the related information of the web application and the display device 200, the server 400 analyzes the current system version of the display device 200 and the target interface that the web application needs to call according to the related information, generates an interface file corresponding to the target interface by using the Python script, and sends the interface file to the display device 200.

After the server 400 determines the target interface, it also determines some type of information for the target interface. The first type is an interface based on basic setting of the display device 200, and basic setting parameters of the display device 200, such as volume, image mode, whether 4K images are supported, etc. of the current display device 200 can be obtained by calling the interface, and basic parameters can be set, such as setting the volume of the display device 200, etc.; the second type is a type of interface based on advanced setting of the display device 200, and functions that can be operated only by requiring rights can be realized by calling such interfaces, for example, reading and writing operations are performed on files in the display device 200, database contents are read and written, or some advanced functions can be set by calling such interfaces, for example, passwords of the display device 200 are set; the third class is a customized class of interfaces that are provided only for some specific web applications.

The server 400 generates respective corresponding interface files for different target interfaces according to the types of the target interfaces and some functions or rights which can be realized by the target interfaces, and the interface files define the use rights, some call parameters and the like of the target interfaces.

Generally, after the browser is loaded into the interface file, the web application program can freely call the target interface corresponding to the interface file, so as to implement some operations on the display device 200, such as setting the volume of the display device 200, setting the password of the display device 200, and the like.

In the above embodiment, the content before the browser loads the interface file may be regarded as a process of authenticating the web application program, and the interface file generated in the authentication process cannot be modified by the web application program, so that the interface file is prevented from being forged, and the abused condition of the display device 200 resources caused by the random call of the web application program by the interface is also prevented, and meanwhile, the user information security and the resource security of the display device 200 are ensured.

In order to simplify the communication process between the display device 200 and the server 400 and to quickly enable both-party communication, in some embodiments, a WebSocket connection may also be established between the display device 200 and the server 400. Fig. 7 is an interaction diagram of a WebSocket connection between a display device 200 and a server 400 according to an embodiment of the present application.

As shown in fig. 7, the controller in the display device 200 is also configured to perform: responding to a webpage application program starting instruction sent by a browser, and initiating a WebSocket connection request to a server 400; in the case of receiving a connection response sent back by the server 400, establishing WebSocket connection with the server 400; the web application and related information of the display device 200 are actively transmitted to the server 400.

Among them, webSocket is a protocol for full duplex communication over a single TCP connection, which makes data exchange between the display device 200 and the server 400 simpler, which allows the server 400 to actively push data to the display device 200. In the embodiment of the present application, based on WebSocket connection, the browser and the server 400 of the display device 200 only need to complete one handshake, and can directly create persistent connection between the two and perform bidirectional data transmission.

Upon receiving the connection request, the server 400 may send a connection response to the display device 200, indicating that a WebSocket connection may be established with the display device 200.

After the WebSocket connection is established, data or information between the display device 200 and the server 400 is transmitted based on the WebSocket, so that a communication process between the display device 200 and the server 400 can be simpler, and communication efficiency is also improved.

In some embodiments, to facilitate the server 400 to generate respective corresponding interface files for different target interfaces, the controller in the display device 200 may further store interface information corresponding to the current system version in the server 400 for configuration content of the system version of the display device 200 before starting the above method or authentication procedure.

The interface information is used to indicate the setting content and authority content of the display device 200 corresponding to all interfaces in the current system version, such as some types of information of the target interfaces described above. Typically, each time the system version of the display device 200 is updated, a new directory is created in the server 400 to store the interface information corresponding to the system version.

In some embodiments, the display device 200 may also save the interface file in a particular location after receiving the interface file so that the browser may automatically load the interface file. Further, the controller in the display device 200 is also configured to perform: storing the interface file under a preset browser directory; and controlling the browser to automatically load the interface file under the browser directory so as to enable the webpage application program to call the target interface.

The read-write permission of the browser directory is only opened to the interface calling operation of the current webpage application program, or is only opened to the current authentication flow, other operations or other programs cannot change the operation, and therefore the safety of the interface file is further guaranteed.

The server 400 provided in the embodiment of the present application may include a controller, where the controller is mainly configured to perform: receiving a web application program transmitted by the display device 200 and related information of the display device 200; generating an interface file required for calling a target interface on the display equipment 200 according to the related information and the pre-stored interface information corresponding to the current system version of the display equipment 200; the interface file is used for determining the use authority and parameters of the target interface; the interface file is sent back to the display device 200 to cause a browser on the display device 200 to load the interface file and the web application to invoke the target interface.

The related information of the display device 200 includes a system version of the display device 200 or a model number of the display device 200, and the related information of the web application includes interface requirement information of the web application, that is, which target interface or interfaces the web application needs to call, and the like.

After receiving the related information of the web application and the display device 200, the server 400 analyzes the current system version of the display device 200 and the target interface that the web application needs to call according to the related information, and then generates an interface file corresponding to the target interface by using the Python script.

After the server 400 determines the target interface, it also determines some type of information for the target interface. The first type is an interface based on basic setting of the display device 200, and basic setting parameters of the display device 200, such as volume, image mode, whether 4K images are supported or not, of the current display device 200 can be obtained by calling the interface, and the basic parameters can be set, such as setting the volume of the display device 200, which is an interface that can be called by all web applications; the second type is an interface based on advanced settings of the display device 200, and functions that can be operated only by permission can be realized by calling the interface, such as reading and writing operations on files in the display device 200, reading and writing database contents, etc., or setting advanced functions, such as setting passwords of the display device 200, etc., the interface can only be opened for web applications supporting the advanced functions or advanced settings; the third class is a customized class of interfaces that are provided only for some specific web applications.

After the browser is loaded to the interface file, the webpage application program can freely call the target interface corresponding to the interface file to realize some operations.

Also, in order to simplify the communication process between the display device 200 and the server 400 and to rapidly implement both-side communication, in some embodiments, a WebSocket connection may be established between the display device 200 and the server 400.

As shown in fig. 7, the controller in the server 400 is further configured to perform: receiving a WebSocket connection request initiated by the display device 200; a connection response is sent back to the display device 200, and a WebSocket connection is established with the display device 200.

In some embodiments, when the interface file is generated in the server 400, the controller is further configured to perform: according to the related information, analyzing the system version of the display device 200 and the target interface required to be called by the webpage application program to be started currently; according to the system version and the target interface, interface information of the target interface is found; and generating an interface file corresponding to the target interface according to the interface information.

The interface information here refers to the type information of the interface and the like, and each target interface has its corresponding display device 200 set content and use authority, for example, interface a may be called by all web applications, interface B may be called only by web applications supporting setting of child lock passwords, interface C may be called only by web application a, and the like.

According to the above interface information, the server 400 may determine the usage rights of each target interface, and further combine the call parameters of different interfaces to generate an interface file corresponding to each target interface by using a programming language or the like.

After the server 400 sends the interface file to the display device 200, the browser of the display device 200 loads the interface file, that is, executes the program of the interface file, so that the web application program can freely call the target interface corresponding to the interface file, thereby realizing some operations on the display device 200, such as setting the volume of the display device 200, setting the password of the display device 200, and the like.

The display device 200 and the server 400 in the foregoing embodiment may perform double-ended communication to implement interface call of a web application on the display device 200, where an interface file generated in the interface call process cannot be modified by the web application, so as to avoid forging the interface file, and avoid misuse of resources of the display device 200 caused by random call of the web application by the interface, and ensure user information security and resource security of the display device 200.

In addition, the authentication process of the web application program is put in the process of starting the web application program, and the authentication is only required to be carried out once, so that the resource consumption of the equipment 200 and the server 400 can be displayed, and a certain performance is improved. The whole authentication process is carried out in the display device 200 and the server 400, normal starting of the webpage application program is not affected, all the interfaces which can be accessed after successful starting are legal, the condition that the interfaces are refused after being accessed is avoided, the problem that the normal use is affected due to the fact that the webpage application program fails to call the interfaces and errors occur is avoided, and user experience is improved.
