Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an implementation environment according to an embodiment of the present invention, as shown in fig. 1, the implementation environment includes a terminal, a first server, and a second server, where the terminal and the server are connected through a network and may perform data interaction.
The terminal may be installed with at least one client, such as a browser client, an application management client, a social application client, and the like, and may implement multiple network functions through the at least one client, so as to meet the use requirements of the user. Taking the example that the web page access is realized through the browser client, the terminal can realize the intercommunication between the browser client and the specified client, and the intercommunication can be established on the basis of the HTTPS protocol to ensure the safety of the interaction and avoid the falsification of the interaction data by other people.
And the specified client may be served by the first server and the second server.
The first server is a background server of the specified client, and may be configured to perform initialization configuration on the specified client, for example, the first server may provide initialization information of the HTTPS for the specified client, such as a certificate, a supported service number, and a command number, so as to perform disaster prevention processing. In addition, the first server can also control the behavior of the specified client by starting and pausing the service number and/or the command number, and if the state of a certain service is abnormal, the first server can stop executing the service by remotely pausing the service number and/or the command number, thereby realizing the flexible control on the behavior of the client.
The second server is a service server, and can be a service for providing installation, service control and the like of the service plug-in for the specified client. When the user uses the appointed client, the user can customize the service to be realized, so that the appointed client downloads the service plug-in from the second server corresponding to the service. For example, when a user wants to implement an application update function through a specified client, the application update service may be set on the specified client. When the service plug-in executes the corresponding service, the service plug-in can be realized through interaction with the second server corresponding to the service plug-in. Each service may have a corresponding second server, and the second server may perform corresponding switching control on its own service, for example, suspend processing of a certain service.
HTTPS Hypertext Transfer Protocol Secure (English: Hypertext Transfer Protocol Secure, acronym: HTTPS, often referred to as HTTP over TLS, HTTP over SSL or HTTP Secure) is a network Secure transport Protocol. On computer networks, HTTPS communicates via hypertext transfer protocol, but encrypts packets with SSL/TLS. The main purpose of HTTPS development is to provide authentication to a network server, protecting the privacy and integrity of the exchanged data.
Jsonpjsonp (JSON with tagging) is a "usage mode" of JSON that can be used to solve the problem of cross-domain data access for mainstream browsers. Due to the same source policy, in general, a web page located in server1.example.com cannot communicate with a server that is not server1.example.com, but the < script > element of HTML is an exception. With this open policy of < script > elements, web pages can get JSON information dynamically generated from other sources, and this usage is called JSONP. The information acquired by the JSONP is not JSON information but arbitrary JavaScript data, and is directly executed by a JavaScript parser instead of being parsed by the JSON parser.
Fig. 2 is a flowchart of a method for communication between a web page and a client according to an embodiment of the present invention. Referring to fig. 2, the method comprises the steps of:
201. initializing a specified client as a server and configuring a target network address and a target port for the specified client.
The target network address is the network address of the specified client, and the target port is the server port of the specified client. The designated client can be configured as a local HTTPS server through the HTTPS protocol, and during the configuration of the server, an IP address, for example, 127.0.0.1, can be allocated to the designated client, and a port number can also be allocated to the designated client, so that the designated client can be accessed by other clients during the operation of the designated client. It should be noted that the target network address is a uniform IP address configured on all designated clients, so that the platform can write the target network address into a web page when the web page is created, and trigger the business processing flow.
It should be noted that the specified client may be an application management type client, and such a type of client operates on a terminal for a long time and can be set to start up, so that the specified client can be used as an interworking carrier to receive requests sent by other clients in an operating state, thereby processing the requests.
Taking HTTPS protocol as an example, during initialization, the designated client communicates with the first server to obtain initialization information of HTTPS, such as a certificate, a supported service number, a command number, and the like, and then initializes HTTPS service to establish a dedicated local HTTPS server on the terminal side. Then, each service plug-in unit is required to be loaded by the appointed client, so that different services can execute the command corresponding to the service number through the corresponding service plug-in unit in the appointed client, and finally, the service steps are realized. HTTPS is used as a communication protocol, so that tampering of communication data by an agent in the middle is mainly prevented, and safety is improved.
202. When a triggering instruction of a specified service on a webpage displayed by a browser client is acquired, a service processing request is generated, and the service processing request is used for requesting the specified client to execute the specified service.
The embodiment of the invention is only described by taking the example of displaying the webpage through the browser client as an example, in an actual scene, the webpage can be displayed through any browser plug-in, for example, through the browser plug-in the social application, a trigger mechanism of a specified service is already provided in a source code of the webpage, for example, in the display process of the webpage, if the current browser client or the social application client is detected to be an old version, an update prompt can be performed based on the new version, an option of the update prompt is displayed on a specified position of the webpage, after a trigger instruction for the option is obtained, it is determined that the specified service on the webpage is triggered, and a service processing request is generated based on a code segment corresponding to the option.
Further, when a specified service on the web page is triggered, a pseudo-random cookie is generated and written to the service processing request. The pseudo-random cookie can be pre-configured in the web page code or the generation algorithm thereof is pre-configured in the web page code, so that in order to avoid abuse of the function by illegal websites and the like, the pseudo-random cookie or the generation algorithm needs to be pre-configured in the web page code for verifying the service processing request by a specified client. Referring to the generation process in fig. 3, when generating a get (get) request, the get request may be regenerated by generating and writing a pseudo-random cookie, thereby initiating an HTTPS request to a specified client.
203. And the browser client sends the service processing request to a specified client.
Specifically, the browser client sends the service processing request to the target network address through the target port, and since the target port and the target network address can point to the designated client, the designated client receives the service processing request through the sending process.
204. And when the appointed client receives the service processing request, checking the domain name carried by the service processing request.
For a business processing request, it will carry the domain name of the source of the business processing request, so as to tell the specified client which web page to link from, and in order to avoid malicious attacks from other websites and other illegal situations, the specified client may only allow requests from some domain names. Taking the first preset condition as the case that the domain name is the preset domain name, the specified client may store the preset domain name, when receiving the service processing request, may determine that the domain name carried by the service processing request is not the preset domain name, if not, the verification fails, and the specified client may ignore or reject the service processing request. When the domain name is determined to be the preset domain name through verification, further verification can be continuously performed on the service processing request.
The preset domain name may be a domain name authenticated by the first server, and may be configured to a specific client by the first server when the client is initialized.
205. And when the domain name meets a first preset condition, the specified client checks the cookie carried by the service processing request.
As described in step 202 above, the service processing request may also carry a cookie, so that the specified client may verify the cookie by means of a cookie or a generation algorithm pre-configured at the client. Taking a second preset condition as an example that the cookie is the same as the preset cookie, the specified client can compare the pre-configured cookie with the cookie carried by the service processing request, if the comparison is consistent, the check is passed, and if the comparison is inconsistent, the check is failed; or, the specified client may generate a cookie according to a pre-configured cookie generation algorithm, compare the generated cookie with the cookie carried by the service processing request, if the comparison is consistent, the check is passed, and if the comparison is inconsistent, the check is failed.
206. And when the cookie accords with a second preset condition, the appointed client responds to the service processing request and determines a service plug-in corresponding to the service number in the appointed client according to the service number carried by the service processing request.
In order to implement a specific service, the service processing request carries a service number, where the service number is used to indicate which type of service is specifically executed by a specified client, and for any service number, a service plug-in corresponding to the service number may be loaded at the specified client, so that the specified client may be processed by the corresponding service plug-in when receiving the service processing request.
The above steps 204 to 206 are processes of checking the service processing request to ensure security, and in the above processes, domain name and cookie checking is taken as an example, for example, the sequence shown in fig. 3, but in an actual scenario, only domain name or cookie checking may be performed to accelerate the checking process and improve the efficiency of service processing. The check of the domain name and the cookie may not be limited to the check sequence, that is, the check process may be performed simultaneously or may be performed in tandem by using any time sequence, which is not limited in the embodiment of the present invention.
The verification process referred to in 204 to 206 is a process of verifying a source of the service processing request, and in an actual scenario, it is generally only allowed for a provider website or a collaboration website of a specific client to open the communication function, so as to ensure the security of service processing.
207. And the appointed client sends the service processing request to the service plug-in, and the service plug-in executes the processing step corresponding to the service processing request by adopting the command corresponding to the service number.
For a service number, its corresponding command number may represent the access right of the service on the terminal. Each service number may correspond to a plurality of command numbers, and the command numbers corresponding to the service numbers may be different, thereby implementing different service processing procedures. Of course, to achieve flexible control, both the service number and the command number may be activated or deactivated by remote control, thereby limiting the processing of a given client. By accessing various services through the extensible and maintainable plug-in technology, the services can be conveniently accessed, and the flexibility and controllability are very strong.
Further, for some services with high requirements on security and privacy, data related to the service is protected by public-private key encryption to prevent the data from being tampered, for example, a channel number of a certain service, and the like. Therefore, each service plug-in can correspondingly store a public key so as to decrypt the data. Correspondingly, the service plug-in adopts the public key corresponding to the service number to decrypt the data in the service processing request to obtain the data to be processed; and the processing module adopts the command corresponding to the service number to correspondingly process the data to be processed.
208. When data needs to be transmitted back to the webpage, the specified client transmits the data back to the webpage.
When any kind of data needs to be transmitted back, the appointed client can transmit back JavaScript data through the JSONP, so that the browser client can analyze and execute the data based on the JavaScript analyzer and perform corresponding product expression.
The method provided by the embodiment of the invention realizes a local server through the appointed client, and can realize the business request and the business processing process by interacting with the local server through the webpage in the business processing process. Furthermore, the method does not need to establish long connection with a background, and the timeliness of service processing is greatly improved. Meanwhile, the JSONP method is used for returning data, so that the stability of service implementation is improved, and the problem of difficulty in returning data in other intercommunication schemes is solved.
For example, when a browser client displays a web page, a user may trigger downloading of any resource through the web page, so that the browser client generates a download request, the browser client may send the download request to a specific client, for example, an application manager client, through an HTTPS protocol, and when the specific client receives the download request, the resource may be downloaded based on a web page link carried in the download request. Certainly, when receiving a download request, the specified client may check the domain name and the cookie thereof, and execute the resource download only when the check is passed, and when executing the resource download process, may also allocate the resource download task to the resource download plug-in to execute, and the resource download plug-in completes the entire download process based on the command corresponding to the resource download task.
For example, when a browser client displays a webpage, a user can trigger installation of any resource through the webpage, so that an installation request is generated by the browser client, the browser client can send the installation request to a specified client, such as an application manager client, through an HTTPS protocol, when the specified client receives the installation request, the resource can be downloaded based on a webpage link carried in the installation request, and after the downloading is completed, the resource is automatically installed. Certainly, when receiving the installation request, the specified client may check the domain name and the cookie thereof, and execute the resource downloading only when the check is passed, and when executing the resource downloading process, may also allocate the resource downloading and installation task to the resource installation plug-in to execute, and the resource installation plug-in completes the whole downloading and installation process based on the command corresponding to the resource downloading and installation task.
