Client data interaction system and method in b/s mode

Abstract

The invention relates to the technical field of the B / S (browser / server) structure, in particular to a client data interaction system and a client data interaction method under the B / S mode. The system comprises a client side and a browser side, the browser side provides JavaScript and a Flash Socket client, the client side provides a socket server and a client local data file, the browser side communicates with the socket server of the client side through the Flash Socket client, and the socket server of the client side executes various commands sent by the browser side and returns execution results. The system and the method adopt the flash platform-based Socket technique to carry out data interaction with the local client side, and utilize business middleware socket server software to receive commands coming from the Socket client on the B / S to execute corresponding operations, both the Socket server and the client carry out data interaction and execution locally on the client side, and thereby the system and the method can perfectly solve cross-browser problems and security and performance problems.

Description

[0001] Technical field: [0002] The invention relates to the technical field of B / S structure, in particular to a client computer data interaction system and method under the B / S mode. [0003] Background technique: [0004] With the development of network technology, many application systems have shifted from the traditional C / S architecture to the B / S architecture. Since the B / S architecture operates the system through the client's browser, access to the client's local resources is limited. The current solutions are based on two technologies, Activex and Java Applet, but these two technologies have the following defects: [0005] 1. Cross-browser issues [0006] Activex technology is a browser plug-in technology led by Microsoft. It belongs to the Microsoft system. It is not compatible with other browsers except IE. In addition, there are many security problems, which lead to great restrictions on the application of this plug-in technology. At present, in the B / S architect...

[0007] 2. Security issues

[0008] The B / S system's control of the client's local resources has always been limited by security issues. Most of the functions cannot be realized like desktop applications. The B / S system indirectly controls the client's local resources through intermediate service software. On the one hand, the business The implementation is placed on the desktop application program, and there is no difference in the development of the original desktop application program. On the other hand, the B / S system cannot directly control the client, and there is an additional security barrier, so that ordinary developers can also develop applications with very high security performance. high application system

[0009] 3. Performance issues

[0010] The Java Applet technology development language is single, and can only be developed with java. When users use it for the first time, they need to download and install a huge java virtual machine. Under the influence of network speed, this process becomes very slow and long
