Instance: Ws.send ("Hello websocket!"); B, Close () method: Using the Close () method, you can turn off the WebSocket connection or terminate the connection attempt. If the connection is closed,
Today, many Web sites are polled for the technology they use to implement push technology. Polling is at a specific time interval (such as every 1 seconds), the browser sends an HTTP request to the server, and then the server returns the latest data to the client's browser. This traditional pattern brings with it the obvious drawback that the browser needs to constantly make requests to the server, but the header of the HTTP request is very long, and the data contained in it may be a small value

generating handshake token, need to make a judgment." First look at the Safari,token generation algorithm using the old version protocol as follows: Take out all the numeric characters in the Sec-websocket-key1 to form a number, here is 1427964708, then divide by the number of spaces in the Key1, this is like 6 spaces, get a numeric value, retain the value of the integer digits, get the value N1 , and Sec-websock
WebSocket is a simple demo program based on javaweb + tomcat, and websocketjavaweb As required by the project, after the frontend initiates a request to the background, the background must be divided into multiple steps for relevant operations, and the time required for completing each step cannot be determined. If ajax is used to repeatedly access the background to obtain real-time data, it is obviously no

to generate token is relatively simple: first of all, Sec-websocket-key and a series of fixed uuid "258EAFA5-E914-47DA-95CA-C5AB0DC85B11" do stitching, and then the concatenation of the string do SHA1 encryption , after getting digest, do a base64 code, you can get token. Also note that the new version and the old version of the handshake protocol back to the client data structure is different, in the att

The Token Generation Method of the new protocol is relatively simple: first, splice the Sec-WebSocket-Key and a fixed UUID "258eafa5-e914-4710995ca-c5ab0dc85b11", and then encrypt the spliced string with SHA1, after obtaining digest, perform a base64 encoding to obtain the Token.
