step 1: starting middleware services in a domestic terminal computer provided with the middleware services, automatically starting built-in HTTP services and WebSocket services by the middleware services, and waiting for a request of a client;
step 2: the browser sends a local program calling request to the middleware service through an HTTP (hyper text transport protocol) or WebSocket protocol, and the middleware service receives the local program calling request, converts the local program calling request into a local application program calling instruction and sends the local application program calling instruction to the local application program;
and step 3: and the local application program is started after receiving the call instruction, sends the UI interface of the local application program to the middleware service, and then transmits the received UI interface to the browser by the middleware service.
Further, in step 1, the middleware service requests the application system server through HTTP at regular time, and detects whether there is a new version of the middleware service, and if there is a new version, automatically downloads the middleware upgrade package from the application system server to the home terminal computer, and then automatically stops the middleware service and performs the upgrade of the middleware service version, and automatically restarts the middleware service after the upgrade of the middleware service version is completed.
Further, in step 2, a secret SM4 packet cipher algorithm is used to encrypt the transmission process of the HTTP or WebSocket transmission protocol.
Further, in step 2, the browser and the middleware service exchange data in a Json data format.
Further, in step 2, a browser based on a kernel is further built in the middleware service, and the middleware service can directly call the local application program.
The invention has the following beneficial effects:
1. according to the invention, by setting the middleware service, when different browsers call the same local application program, the middleware service can transmit data with different browsers, and then sends a call instruction to the local application program according to the call requirement, so that different browsers do not need to design separate plug-ins, the problem of difficult cross-browser call is solved, and simultaneously, the UI (user interface) of the system is displayed consistently;
2. the middleware service can access the application system server side through HTTP at regular time and automatically upgrade the version, so that the running stability and compatibility of the middleware service can be ensured;
3. the transmission process of the HTTP or WebSocket transmission protocol adopts the SM4 block cipher algorithm for encryption, thereby realizing safe data transmission;
4. the browser is embedded in the middleware service, and in the interaction between different browsers and the middleware service, the Web system can be opened by enabling the middleware to use the embedded browser, so that all users use the uniform embedded browser, developers do not need to write compatible codes of various browsers, and the development efficiency is greatly improved.
