Socket網(wǎng)絡(luò)編程是一種基于網(wǎng)絡(luò)通信的編程方式，它允許不同的計(jì)算機(jī)之間進(jìn)行數(shù)據(jù)交換，在Socket網(wǎng)絡(luò)編程中，客戶端和服務(wù)器端通過(guò)套接字（Socket）進(jìn)行通信，套接字是一種特殊的文件描述符，用于表示網(wǎng)絡(luò)連接的一個(gè)端點(diǎn)，本文將介紹使用Socket網(wǎng)絡(luò)編程的基本步驟。
1、創(chuàng)建套接字
我們需要?jiǎng)?chuàng)建一個(gè)套接字，在Linux系統(tǒng)中，可以使用socket()函數(shù)來(lái)創(chuàng)建套接字，這個(gè)函數(shù)需要傳入兩個(gè)參數(shù)：一個(gè)是地址族（Address Family），另一個(gè)是套接字類型（Socket Type），常用的地址族有AF_INET（IPv4）和AF_INET6（IPv6），套接字類型有SOCK_STREAM（TCP）和SOCK_DGRAM（UDP）。
includeinclude int main() { int sockfd = socket(AF_INET, SOCK_STREAM, 0); if (sockfd < 0) { perror("socket"); exit(1); } return 0; }
2、綁定套接字
創(chuàng)建好套接字后，我們需要將其綁定到一個(gè)地址上，這可以通過(guò)bind()函數(shù)實(shí)現(xiàn)。bind()函數(shù)需要傳入三個(gè)參數(shù)：套接字描述符、地址結(jié)構(gòu)體指針和地址長(zhǎng)度，地址結(jié)構(gòu)體通常包含IP地址和端口號(hào)。
includeinclude include include include int main() { struct sockaddr_in server_addr; memset(&server_addr, 0, sizeof(server_addr)); server_addr.sin_family = AF_INET; server_addr.sin_port = htons(8080); inet_pton(AF_INET, "127.0.0.1", &server_addr.sin_addr); int sockfd = socket(AF_INET, SOCK_STREAM, 0); if (sockfd < 0) { perror("socket"); exit(1); } if (bind(sockfd, (struct sockaddr *)&server_addr, sizeof(server_addr)) < 0) { perror("bind"); exit(1); } return 0; }
3、監(jiān)聽(tīng)套接字
綁定好套接字后，我們需要對(duì)其進(jìn)行監(jiān)聽(tīng)，這可以通過(guò)listen()函數(shù)實(shí)現(xiàn)。listen()函數(shù)需要傳入兩個(gè)參數(shù)：套接字描述符和最大連接數(shù)，當(dāng)有新的客戶端連接時(shí)，服務(wù)器端的套接字會(huì)進(jìn)入阻塞狀態(tài)，等待客戶端的連接請(qǐng)求。
