websocket service

. Can even create a specially tailored for Layim WebSocket service, before explaining my development road, but also to recommend a more complete solution Tio-im, of course, I also learn from the source code design ideas. But its implementation is more powerful, because my level is limited, I can only Tiger, carelessly wrote a pass. But it can still be used.Tio-im Address: Https://gitee.com/xchao/tio-imProje

Nginx can only proxy HTTP requests, if you want to implement proxy websocket requirements, you need to add the "Upgrade" field in the request to upgrade the request from HTTP to WebSocket.The configuration is as follows:http{map $http _upgrade $connection _upgrade{ defaultupgrade; ' close;}server{ ...location /chat/{proxy_pass Http://backend;proxy_http_version 1.1; #以下配置添加代理头部: proxy_set_headerUpgrade $http _upgrade; proxy_set_headerConnection $conne

1.websocket Introduction In the past, the browser wanted to get the server data by sending an HTTP request and then waiting for the server to respond. That is, the browser side has always been the initiator of the entire request, only if it is active, to obtain data. To allow the browser side to get real-time data on the server side, it is necessary to constantly initiate requests to the server. Although the actual data has not been obtained in

complex WebSocket servers. This library may not contain the cool features of all the other libraries, but it doesn't matter, because it's highly configurable and you can easily make it do what you want. It can be run as a console application or as a Windows service in ASP. In the literature, it is recommended to run the server as a system service. From my experi

, in the usual use, can be reused HTTP port and function, in addition, they have no other connection, but is completely independent protocol, usually, HTTP is a one-way web services, While WebSocket is full-duplex, the server and the client can transmit information in real time, and they can be deployed simultaneously on the HTTP server when referencing, especially in Nodejs. WebSocket and socketsSo wha

For a new job, the first task is related to this, did not contact before, no way, various degrees Niang, Google, most of them are words, or is a specific configuration environment is not affixed to the configuration ... WebSocket protocolWebSocket is a protocol for full-duplex communication on a single TCP connection. The WebSocket communication protocol was established by the IETF as standard RFC 645

/domain name and the port connection server, when the server side has the notification to be able to callback OnMessage method 　　　　 3, and then call the Connect method for the connection 　　　 4, after the connection can send a message, send a message is also very simple, in addition to support string sent also support byte send, OK, the client is so happy to write (detailed code see behind packaged demo). 　　　 Second, the creation of the service s

when you have information.Server: OK, sometimes I will tell you.Service side: UpdatedService side: Updated againService side: ha haha haha ah haha hahaService side: Laughing at me ha ha haha hahaSo why would he solve the problem of consuming resources on the server? In fact, we use the program is to go through two layers of proxy, that is, HTTP protocol in Nginx and other servers, and then sent to the corresponding handler (PHP, etc.) to deal with. In short, we have a very fast operator (Nginx)

browser and server only need to do a handshake, and then a fast channel is formed between the browser and the server. The data can be transmitted to each other directly between the two. In this WebSocket agreement, there are two major benefits to our instant service:1. Header. The header that communicates with each other is very small-about 2 Bytes.2. Server Push. Server push, the server no longer passivel

WebSocket is primarily designed to address the application of flexible communication applications on the web with long connections, but WebSocket itself is only a basic protocol and is not flexible for messages, after all WebSocket only provides the basic data format for text and binary streams. In the actual application is more inclined to the processing of obje

According to the OSI network layered model, IP is the Network layer protocol, TCP is the Transport Layer protocol, and HTTP is the application layer protocol. Between these three, Spdy and WebSocket are HTTP-related protocols, and TCP is the HTTP underlying protocol.One, the lack of HTTPThe HTTP protocol has been used for many years and has found some deficiencies, mainly in performance, including:HTTP connection problems, the interaction between the

This is a creation in Article, where the information may have evolved or changed. The message notification in the project is used by WebSocket, which feels better than HTTP long connection chunking, and is hereby recorded.The WebSocket protocol is expressed in WS. In addition, there is the WSS protocol, which represents the encrypted WebSocket protocol, which cor

A little trial, found that slack chat function is quite powerful, looked at the network request, the discovery is based on WebSocket implementation. Immediately mention the interest, want to know the next strong WebSocket. Fir

WebSocket protocol is a new protocol for HTML5.It implements browser-to-server full-duplex communication (Full-duplex). Browsers and servers only need to do a handshake, and then a fast channel is formed between the browser and the server. The data can be transmitted to each other directly between the two.

map it to the server for processing. The following code uses a simple user registration method to demonstrate the interaction process between HTML 5 and websocket using josn. It is very convenient to use because of encapsulation. HTML: The function is very simple. After the websocket service is connected, the registration information is submitted. Of course, t
