Data communication method and apparatus

Abstract

The application discloses a data communication method and an apparatus, wherein the method and the apparatus are applied to a data communication system including a client and a server terminal. One or more browser programs are installed at the client; flash plug-in units are installed internally in the browser programs; and flash application files are contained in browser pages established by the browser programs. The data communication method comprises: a browser program operates a flash application file in an established browser page in a built-in flash plug-in unit so as to try to expose local connection interface in the flash application file; and then when the local connection interface is exposed successfully, the browser program establishes a communication channel with the server terminal and carries out data communication with the server terminal by the communication channel. With utilization of the data communication method and the apparatus, a technology of multi-page, cross-domain and cross-browser sharing of a socket communication channel can be realized; and reliability, completeness and robustness of data communication can be improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data communication method and device. Background technique [0002] The browser generally uses HTTP for data communication with the server, but in some scenarios, for example, where real-time data needs to be guaranteed, a socket (socket) communication channel can be used for data communication with the server. Compared with HTTP, socket communication is a lower-level persistent connection communication method. When the socket connection is established, the client and the server can send and receive data bidirectionally in real time. When the browser uses the socket communication channel to interact with the server, it can establish a socket communication channel with the server for each browser page, such as figure 1 As shown, this communication method requires the server to invest more communication resources, which increases hardware and management cost...

AI Technical Summary

Problems solved by technology

[0006] The existing technology can only share a socket communication channel between multiple pages of the same type of browser, and cannot realize the sharing of socket communication channels across browsers

When the public socket communication channel disappears, each type of browser will provide a public socket communication channel, for example, the FireFox browser provides a public socket communication channel, the IE browser provides a public socket communication channel, and the Safari browser also provides a The public socket communication channel cannot guarantee the uniqueness of the public socket communication channel, which occupies a large amount of communication resources on the server side

In the scheme of realizing public socket communication channel based on cookie information, when two pages find that there is no sign of public socket communication channel in the cookie information at the same time, they will create a public socket communication channel, causing the same type of browser to provide multiple shared socket communication channel, which further intensifies the occupation of communication resources on the server side

In addition, for browsers that support local databases, when the browser where the page that provides the public socket communication channel exits abnormally, the flag of the public socket communication channel in the local database cannot be cleared, so the public socket communication channel cannot be re-established , so that the data communication fails, and the reliability, integrity and robustness of the client data communication cannot be guaranteed
