使用Java编写HTTP服务器

import?java.io.*;

import?java.net.*;

public?class?HttpServer?{

public?static?void?main(String[] args)?throws?IOException {

int?port?= 8080; // 服务器监听的端口号

ServerSocket?serverSocket?= new?ServerSocket(port);

System.out.println("HTTP服务器已启动，正在监听端口："?+ port);

while?(true) {

Socket?socket?= serverSocket.accept(); // 接受客户端连接请求

new?Thread(new?HttpRequestHandler(socket)).start(); // 创建新线程处理请求

}

}

}

class?HttpRequestHandler?implements?Runnable?{

private?Socket socket;

public?HttpRequestHandler(Socket socket)?{

this.socket = socket;

}

@Override?

public?void?run()?{

try?{

BufferedReader?input?= new?BufferedReader(new?InputStreamReader(socket.getInputStream()));

PrintWriter?output?= new?PrintWriter(socket.getOutputStream());

String?request?= input.readLine(); // 读取客户端请求行

System.out.println("收到请求："?+ request);

// 这里可以添加逻辑来处理请求并生成响应

String?response?= "Hello, World!"; // 示例响应内容

output.println("HTTP/1.1 200 OK"); // 示例响应状态码和响应头

output.println("Content-Type: text/plain"); // 示例响应头，指定内容类型为纯文本

output.println("Content-Length: "?+ response.length()); // 示例响应头，指定内容长度

output.println(); // 空行，分隔响应头和响应体

output.println(response); // 发送响应体

output.flush(); // 刷新输出流，确保数据被发送出去

} catch?(IOException e) {

e.printStackTrace();

} finally?{

try?{

socket.close(); // 关闭客户端连接

} catch?(IOException e) {

e.printStackTrace();

}

}

}
