好的,下面是用 C 语言编写一个简单的 HTTP 服务器的代码示例:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#define PORT 8080
int main()
{
int server_fd, new_socket;
struct sockaddr_in address;
int addrlen = sizeof(address);
char *response = "HTTP/1.1 200 OK\nContent-Type: text/plain\nContent-Length: 12\n\nHello World!";
// create socket
if ((server_fd = socket(AF_INET, SOCK_STREAM, 0)) == 0) {
perror("socket failed");
exit(EXIT_FAILURE);
}
// bind address and port to socket
address.sin_family = AF_INET;
address.sin_addr.s_addr = INADDR_ANY;
address.sin_port = htons(PORT);
if (bind(server_fd, (struct sockaddr *)&address, sizeof(address)) < 0) {
perror("bind failed");
exit(EXIT_FAILURE);
}
// listen for incoming connections
if (listen(server_fd, 3) < 0) {
perror("listen failed");
exit(EXIT_FAILURE);
}
// accept incoming connection and send response
if ((new_socket = accept(server_fd, (struct sockaddr *)&address, (socklen_t*)&addrlen)) < 0) {
perror("accept failed");
exit(EXIT_FAILURE);
}
send(new_socket, response, strlen(response), 0);
printf("Hello message sent\n");
return 0;
}
