套接字的編程步驟
在使用之前須鏈接庫函數(shù)：工程->設(shè)置->Link->輸入ws2_32.lib，OK！
SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,0);//創(chuàng)建套接字（socket）。
SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);//轉(zhuǎn)換Unsigned short為網(wǎng)絡(luò)字節(jié)序的格式
addrSrv.sin_family=AF_INET;
addrSrv.sin_port=htons(6000);
客戶端代碼如下：
#include <Winsock2.h>
#include <stdio.h>
void main()
{
WORD wVersionRequested;
WSADATA wsaData;
int err;
wVersionRequested = MAKEWORD( 1, 1 );
err = WSAStartup( wVersionRequested, &wsaData );加載套接字庫
if ( err != 0 ) {
return;
}
if ( LOBYTE( wsaData.wVersion ) != 1 ||
HIBYTE( wsaData.wVersion ) != 1 ) {
WSACleanup()( );
return; 
}
SOCKET sockClient=socket(AF_INET,SOCK_STREAM,0);創(chuàng)建套接字（socket）。
SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr=inet_addr("127.0.0.1");
addrSrv.sin_family=AF_INET;
addrSrv.sin_port=htons(6000);
connect(sockClient,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR));向服務(wù)器發(fā)出連接請(qǐng)求（connect）。
char recvBuf[100];和服務(wù)器端進(jìn)行通信（send/recv）。
recv(sockClient,recvBuf,100,0);
printf("%s\n",recvBuf);
send(sockClient,"This is lisi",strlen("This is lisi")+1,0);
closesocket(sockClient);關(guān)閉套接字。
WSACleanup()();//必須調(diào)用這個(gè)函數(shù)清除參數(shù)
}

H5 Web Sockets for Bidirectional Real-time Data H5 Web Sockets for Bidirectional Real-time Data

29 Jul 2025

H5WebSockets is a full-duplex communication protocol provided by HTML5, which allows the browser to establish a persistent connection with the server and realizes low-latency bidirectional data transmission. 1. It continuously interacts through a single TCP connection, avoiding the high latency and waste of resources caused by traditional HTTP polling; 2. It is suitable for online chat, real-time market, collaborative editing, game synchronization and other scenarios that require instant push; 3. When using it, the front-end creates connections and listens to events such as onopen, onmessage, onclose and onerror, and the back-end can use Node.js or Python to build services; 4. Notes include priority use of encryption protocols wss:// and processing network

Mastering the Go Standard Library for Web Development Mastering the Go Standard Library for Web Development

02 Aug 2025

Go's standard library is sufficient to build production-grade web applications without the need for third-party frameworks. 1. Use net/http to create a server, implement routing through http.ServeMux, and http.HandlerFunc converts the function into a processor; 2. The middleware is implemented by wrapping http.Handler, which can customize logs, authentication, CORS and other logic and call them in a chain; 3. Use encoding/json to process JSON requests and responses, and use http.Error to return standard errors; 4. Use http.FileServer to serve static files, and combine StripPrefix and fallback to support SPA; 5. Use flag or os.

How to use Go's standard library for web development How to use Go's standard library for web development

Go's net/http package provides everything you need to build a web application without the need for a third-party framework. Use http.HandleFunc to register the route, http.ListenAndServe starts the server, and defaults to use DefaultServeMux to handle requests. You can distinguish GET, POST and other methods through r.Method, and use http.Error to return the appropriate status code. Static files are provided through http.FileServer and http.StripPrefix. Request data can be read from form or json.NewDecoder parsed by JSON. C should be set when responding to JSON
