information is excerpted from Wikipedia (HT T P S://z H. w i ki p e d i a. o r g/w I ki/w e b so cket) Simply put, WebSocket is to reduce the number of connections between client and server, reduce system resource overhead, only need one HTTP handshake, the entire communication process is established in a connection/state, also avoids the non-state of HTTP, the service side will remain connected with the client, Until you close the request, at t

message arrives, when the connection is closed, and when the error occurred. The WebSocket protocol defines two URL schemes, where WS and WSS represent unencrypted and encrypted communication between the client and the server. WS (WebSocket) is similar to HTTP URLs, while the WSS (

("websocketerror!");};The first line of code is to request a WebSocket object, the parameter is the server-side address that needs to be connected, as the HTTP protocol begins, the URL of the WebSocket protocol uses ws://, and the security WebSocket protocol starts with wss://.The second line to the fifth behavior

SslSSL (Secure Socket Layer) is simply a cryptographic technique through which we can establish a secure communication link on both sides of the communication, so that both sides of the data interaction can communicate securely without worrying about the data being stolen. For an in-depth knowledge of SSL, you can read this article: overview of the operating mechanism of SSL/TLS protocolWssWSS is the abbreviation for Web Socket Secure, which is an encrypted version of

With the help of node practices WebSocket, node practices WebSocket I. WebSocketOverview WebSocket protocol,It is based on TCP rather than HTTP. As follows: Ws: // 127.0.0.1 or wss: // 127.0.0.1 is a WebSocket request. Note:WsWebSocketProtocol, wssIndicates en

As we all know, the HTTP protocol is stateless and interacts with the server based on Request/response, which is what we often call the single-mode. However, with the development of the Internet, the two-way communication between the browser and the server is increasing, and the way of long polling to the servers to get the latest data and push effect is becoming more and more satisfying. HTML5 Standard, also provides us with the browser and the service side of the Duplex Communication protocol

In HTML5 specifications, my favorite Web technology is the rapidly becoming popular WebSocket API. WebSocket provides a popular technology to replace the Ajax technology we have been using over the past few years. This new API provides a method to effectively push messages from the client to the server using simple syntax. Let's take a look at HTML5 WebSocket API

WebSocket SecurityThe WebSocket protocol is a young technology, and brings with it some risks. Decades of experience has taught the web community some best practices around HTTP security, but the security best practi Ces in the WebSocket world aren ' t firmly established, and continue to evolve. Nevertheless, some themes has emerged and they is described in this

In this way, WSS can compete with professional software developers to some extent, because it allows users to create and customize their own websites. in just a few minutes, a user can create a WSS site, add several lists and document libraries, and customize the appearance of the site to meet certain commercial needs. an identical solution, if ASP.
