Question

这是我的java http服务器程序：

package alan;

import java.io.BufferedReader; 
import java.io.IOException; 
import java.io.InputStreamReader; 
import java.net.ServerSocket; 
import java.net.Socket; 

public class SimpleHTTPServer { 
    public static void main(String args[] ) throws IOException { 
        ServerSocket server = new ServerSocket(8080); 
        System.out.println("Listening for connection on port 8080 ...."); 
        while (true) { 
            Socket clientSocket = server.accept(); 
            InputStreamReader isr = new          InputStreamReader(clientSocket.getInputStream()); 
        BufferedReader reader = new BufferedReader(isr); 
        String line = reader.readLine(); 
        while (!line.isEmpty()) { 
            System.out.println(line); 
            line = reader.readLine(); 
        } 
    } 
} 
}

当这个程序正在运行时，如果我写＆＃34; http://localhost:8080＆＃34;在Web浏览器上，程序可以处理Http get请求，并在Eclipse控制台上输出结果，但我想通过使用java代码来完成。

实际上，首先，我想创建一个名为SimpleHTTPClient的类，我想创建一个与SimpleHTTPServer类的TCP Socket连接，并通过java代码将HTTPGET请求发送到我的localhost。我怎样才能做到这一点？实际上，我可以发送带有URL连接的HTTPGET请求，如下所示：

package alan;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;
import java.net.URL;
import java.net.URLConnection;
import java.net.UnknownHostException;

public class SimpleHTTPClient {
    static Socket socket = null;

    public static void main(String args[]) throws UnknownHostException,     IOException {
    URL oracle = new URL("http://localhost:8080");
    URLConnection yc = oracle.openConnection();
    BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
    String inputLine;
    while ((inputLine = in.readLine()) != null) 
        System.out.println(inputLine);
    in.close();
}
}

但我想通过TCP套接字连接向我的 localhost 发送HTTPGET请求。我怎么能这样做？

为此，您必须打印请求标题。对于基本HTTP请求，只需在标头中添加http方法和主机。

见下面的代码

Socket s = new Socket(InetAddress.getByName("stackoverflow.com"), 80);
PrintWriter pw = new PrintWriter(s.getOutputStream());
pw.println("GET / HTTP/1.1");
pw.println("Host: stackoverflow.com");
pw.println("");
pw.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
String t;
while ((t = br.readLine()) != null) {
    System.out.println(t);
}
br.close();

祝你好运
