首先模擬一個http服務端，用於接收請求

package bhpp.rsserver.test;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

import javax.net
 
.ssl.HttpsURLConnection;

import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
public class HttpServerTest {

    private ExecutorService pool=Executors.newCachedThreadPool();
    public HttpServerTest(){
        try {
            HttpServer server=HttpServer.create
 
(new InetSocketAddress(6666), 3000);
            server.createContext("/",new Handler());
            server.setExecutor(pool);
            server.start();
            System.out.println("Http 啟動...");
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    class Handler implements HttpHandler{

        @Override
        public void handle(HttpExchange exc) throws IOException {

            BufferedReader reader=new BufferedReader(new InputStreamReader(exc.getRequestBody
 
()));
            //用於儲存請求資訊
            String requestMessage=reader.readLine();
            System.out.println(requestMessage);
            String response="true";
            exc.sendResponseHeaders(HttpsURLConnection.HTTP_OK,
                    response.getBytes().length);
            OutputStream out=exc.getResponseBody();
            out.write(response.getBytes());
            out.flush();
            out.close();
            exc.close();
        }

    }

    public static void main(String[] args) {
        new HttpServerTest();
    }

}

其次socket傳送請求連線http服務

package bhpp.rsserver.test;
import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import java.net.URLEncoder;

/**TCP 客戶端連線HTTP服務端

public class TcpToHttpClient{

    public TcpToHttpClient() throws IOException {
        //sendPost();
        sendGet();
    }
    public static void main(String[] args) throws IOException {
        new TcpToHttpClient();
    } 

    /**post方式
     * @throws IOException
     */
    public void sendPost() throws IOException{

        String path = "/";  
        String data = URLEncoder.encode("username", "utf-8") + "=" + URLEncoder.encode("zs", "utf-8") + "&" +  
                URLEncoder.encode("pwd", "utf-8") + "=" + URLEncoder.encode("32", "utf-8");
        SocketAddress dest = new InetSocketAddress("localhost", 6666);
        Socket socket = new Socket();
        socket.connect(dest);

        OutputStreamWriter streamWriter = new OutputStreamWriter(socket.getOutputStream(), "utf-8");
        BufferedWriter bufferedWriter = new BufferedWriter(streamWriter);

        bufferedWriter.write("POST " + path + " HTTP/1.1\r\n");
        bufferedWriter.write("Host: " + "localhost" + "\r\n");
        bufferedWriter.write("Content-Length: " + data.length() + "\r\n");
        bufferedWriter.write("Content-Type: application/x-www-form-urlencoded\r\n"); 
        bufferedWriter.write("\r\n");
        bufferedWriter.write(data);
        bufferedWriter.flush();
        bufferedWriter.write("\r\n"); 
        bufferedWriter.flush();

        BufferedInputStream streamReader = new BufferedInputStream(socket.getInputStream());  
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(streamReader, "utf-8"));  
        String line = null;
        while((line = bufferedReader.readLine())!= null){  
            System.out.println(line);  
        }  
        bufferedReader.close();  
        bufferedWriter.close();  
        socket.close();  
    }

    /**get方式
     * @throws IOException
     */
    public void sendGet() throws IOException{

        String path = "/";
        SocketAddress dest = new InetSocketAddress("localhost", 6666);
        Socket socket = new Socket();
        socket.connect(dest);
        OutputStreamWriter streamWriter = new OutputStreamWriter(socket.getOutputStream());
        BufferedWriter bufferedWriter = new BufferedWriter(streamWriter);

        bufferedWriter.write("GET " + path + " HTTP/1.1\r\n");
        bufferedWriter.write("Host: " + "localhost" + "\r\n");
        bufferedWriter.write("\r\n");
        bufferedWriter.flush();

        BufferedInputStream streamReader = new BufferedInputStream(socket.getInputStream());
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(streamReader, "utf-8"));  
        String line = null;
        while((line = bufferedReader.readLine())!= null){
            System.out.println(line);
        }
        bufferedReader.close();
        bufferedWriter.close();
        socket.close();
    }
}
