Problems solved by technology

[0005] The purpose of the present invention is to overcome the defect that the current WebSocket object does not include the attribute of obtaining client hardware information, and proposes a method for obtaining client hardware information based on WebSocket, which realizes WebSocket object obtaining client by calling the extended JavaScript interface. Hardware information, and this method has high security, ensuring that the customer's hardware information cannot be modified

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, a method for obtaining client hardware information based on WebSocket, the method specifically includes:

[0029] Step 1) Extend the custom JavaScript interface to the general WebSocket object;

[0030] The general WebSocket object is all WebSocket objects created by the client;

[0031] Such as figure 2 As shown, the step 1) specifically includes:

[0032] Step 1-1) In the browser kernel, add a JavaScript interface attribute value or method to the general WebSocket object;

[0033] Step 1-2) define the function mapping relationship of the extended JavaScript interface attribute value or method in step 1-1) in the browser kernel, and map to the custom function inside the browser;

[0034] Step 1-3) in the internal custom function of step 1-2), call the function that the extended self-definition ...

Abstract

The invention provides a WebSocket based client-side hardware information obtaining method. The WebSocket based client-side hardware information obtaining method comprises the steps that 1, a JavaScript interface function is expanded and customized for a commonly used WebSocket object; 2, a WebSocket object is created on the client-side, connection with a server is established, and the JavaScript interface function expanded and customized in the step 1 is called; 3, a Web engine kernel acquires corresponding equipment hardware information according to the interface function called by the WebSocket object and returns the information to the client-side; 4, the client-side includes the returned equipment hardware information in data messages and sends the information to a server; 5, the server processes the data messages and returns the equipment hardware information to the client-side; 6, the client-side continues to send the data messages to the server according to returned processing results till communication is completed; 7, after communication is completed, WebSocket connection is closed.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to a method for acquiring client hardware information based on WebSocket. Background technique [0002] With the maturity of HTML5 technology and the finalization of HTML5 specification, as an emerging technology and with the feature of supporting cross-platform, HTML5 is more and more welcomed by developers. As one of the key technologies of HTML5, WebSocket supports full-duplex communication and saves network bandwidth. It is also the preferred communication method for developers when developing Web application communication or even cross-platform communication. [0003] In the standard WebSocket protocol, the WebSocket object has relatively limited attributes and methods, such as: attribute value URL, methods send and close, and so on. In the process of developing a web application, sometimes there are more requirements for the information to be included in the s...
