Java uses WebSocket + tail commands to implement real-time Web logs In Linux, you often need to view the Real-Time Output content of log files.tail -fOrtaifCommand. To view Real-time logs, you may need to first connect to the Linux host through SSH. The steps are troublesome. If the server is in the production environment, various permissions may be controlled. Web-based Real-time logs can solve this proble

The emergence of the WebSocket protocol is undoubtedly one of the most exciting features of HTML5. It can effectively replace the Comet technology and Flash XmlSocket to implement HTTP-based bidirectional communication. Currently, mainstream browsers such as Chrome, Firefox, IE10, Opera10, and Safari all support WebSocket. In addition, some good WebSocket project

In the Linux operating system, it is often necessary to view the real-time output of log files, usually using tail -f or tailf commanding. Viewing real-time logs may require SSH to connect to a Linux host first, the steps are cumbersome, and if you are a production environment server, you may also be able to control various permissions. Real-time web-based logs can solve this problem.Because the traditional HTTP protocol is the request/response mode, and the real-time log needs constant output,

WebSocket Protocol IntroductionThe WebSocket protocol is a network protocol that allows two connected ends to have full-duplex message communication on a single TCP connection.In the WebSocket scenario, the connection is established in a way that interacts with HTTP and websocket endpoints. The connected party sends a

I've been thinking about a problem lately: How does a server proactively send messages to a browser? The traditional web is a browser that actively sends requests to the server, and the server returns data to the browser after it receives the request. If you want to implement a server to proactively send messages to the browser, that is, the implementation of the Web version of instant communication should do? There seems to be no answer. Before the use of polling to implement pseudo-instant com
