c语言怎么写web服务器
要使用C语言编写一个Web服务器，你需要了解HTTP协议、套接字编程以及多线程等技术，下面是一个简单的C语言Web服务器的实现过程：,1、需要包含一些必要的头文件：,2、定义常量和全局变量：,3、创建套接字并绑定地址：,4、创建线程处理客户端连接：, ,#include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <arpa/inet.h> #include <sys/socket.h> #include <netinet/in.h> #include <pthread.h>,#define PORT 8080 #define BUFFER_SIZE 4096 #define MAX_CONNECTIONS 5 int server_fd, client_fd; struct sockaddr_in server_addr, client_addr; pthread_t thread_id; int client_count = 0;,server_fd = socket(AF_INET, SOCK_STREAM, 0); memset(&server_addr, 0, sizeof(server_addr)); server_addr.sin_family = AF_INET; server_addr.sin_addr.s_addr = INADDR_ANY; server_addr.sin_port = htons(PORT); bind(server_fd, (struct sockaddr *)&server_addr, sizeof(server_addr)); listen(server_fd, MAX_CONNECTIONS);,void *handle_client(void *arg) { int client_socket = *((int *)arg); char buffer[BUFFER_SIZE]; char oldPath[1024] = {0}; char newPath[1024] = {0}; ssize_t bytesRead; char fileName[1024] = {0}; char fileType[1024] = {0}; char fullPath[1024] = {0}; char response[BUFFER_SIZE] = “HTTP/1.1 200 OKr ContentType: text/htmlr r “; char errorResponse[BUFFER_SIZE] = “HTTP/1.1 404 Not Foundr ContentType: text/htmlr r “; char defaultPage[] = “<!DOCTYPE html><html><head><title>Welcome</title></head><body><h1>Welcome to...
