Embodiment Construction

[0032] The present invention utilizes general-purpose terminals such as smart phones, tablets, smart TVs, and computers with WEB browsers, and implements search and positioning of devices in a local area network or a specified network segment through HTTP requests based on WEB JavaScript.

[0033] Take the search for all implementation methods in the common LAN segment 192.168.0.1~192.168.0.254 as an example, such as figure 1 Shown:

[0034] Step 1: The web browser software opens the page containing the device search function script, such as figure 2 shown.

[0035] Step 2: Click as figure 2 As shown in "203 Search button", start the search script to search.

[0036] Step 3: The search script traverses the target network range set by the user or the system, from figure 2 The shown "201 start IP: 192.168.0.1" begins to construct the URL of the HTTP request one by one for detection; the detection method: add SRC as the JavaScript node of the URL through the DOM operation ...

Abstract

The invention discloses a method for searching equipment in a local area network or an appointed network segment in a webpage. The method comprises the following steps: opening a webpage comprising an equipment search function script by webpage browser software; after a specific browser event is triggered, starting the search script for performing searching; traversing a target network range set by a user or system by the search script for performing detection, wherein a detection manner is as follows: a URL (Uniform Resource Locator) of an HTTP (Hyper Text Transport Protocol) request is constructed from a starting IP (Internet Protocol) one by one, and remote procedure call is realized by adding an SRC (Standard Requirement Code) as a JavaScript of the URL, and the detection whether equipment exists on the IP address or not is completed according to a returning result; after receiving the URL of the request, returning a script text comprising a 'convention callback function name (convention series parameter)'; and after receiving the script text returned by the equipment, calling a function corresponding to the 'convention callback function name', wherein the function detects equipment information contained in the 'convention series parameter' and updates the equipment information into an equipment list.

Description

Technical field: [0001] The invention relates to network device search, in particular to a method for searching devices in a local area network or a specified network segment in a web page by means of a standard browser. Background technique: [0002] Web page (WEB) is a computer language system, based on Hypertext Transfer Protocol (HTTP: Hyper Text Transport Protocol), Hypertext Markup Language (HTML: HyperText Markup Language), JavasSript (a widely used scripting language), cascading Style sheets (CSS: Cascading Style Sheets)-based standards and technologies, Document Object Model (English: Document Object Model, abbreviated as DOM), is a standard programming interface recommended by the W3C organization for processing Extensible Markup Language, which constitutes a browser The basic framework for displaying browser content, with the help of JavaScript, dynamic WEB content generation and control can be performed. [0003] Web Browser (web browser) is an application softw...
