c语言怎么进行http编程

在C语言中进行HTTP编程,通常有两种方法:

使用原生的socket编程

创建一个TCP监听socket,等待客户端连接。

解析请求,并生成HTTP响应数据。

将响应发送回客户端。

```c

include

include

define PORT 8080

define BUFFER_SIZE 1024

int main() {

int server_fd, client_fd, addr_len;

struct sockaddr_in server_addr, client_addr;

char buffer[BUFFER_SIZE];

// 创建套接字

if ((server_fd = socket(AF_INET, SOCK_STREAM, 0)) == 0) {

perror("socket failed");

exit(EXIT_FAILURE);

}

// 配置服务器地址

server_addr.sin_family = AF_INET;

server_addr.sin_addr.s_addr = INADDR_ANY;

server_addr.sin_port = htons(PORT);

// 绑定套接字

if (bind(server_fd, (struct sockaddr *)&server_addr, sizeof(server_addr)) < 0) {

perror("bind failed");

exit(EXIT_FAILURE);

}

// 监听连接

if (listen(server_fd, 3) < 0) {

perror("listen");

exit(EXIT_FAILURE);

}

addr_len = sizeof(client_addr);

// 接受客户端连接

if ((client_fd = accept(server_fd, (struct sockaddr *)&client_addr, (socklen_t *)&addr_len)) < 0) {

perror("accept");

exit(EXIT_FAILURE);

}

// 读取并打印客户端请求

read(client_fd, buffer, BUFFER_SIZE);

printf("Client request: %s\n", buffer);

// 构造HTTP响应

char response[] = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n

Hello, World!
