java 使用HttpURLConnection发送数据简单实例

import java.io.*;
import java.net.*;

public class PostExample {
  public static void main(String[] argv) throws Exception {
     URL url = new URL("http://www.javacourses.com/cgi-bin/names.cgi");
     HttpURLConnection connection = (HttpURLConnection) url.openConnection();
     connection.setRequestMethod("POST");
     connection.setDoOutput(true);
     PrintWriter out = new PrintWriter(connection.getOutputStream());
    // encode the message
     String name = "name="+URLEncoder.encode("Qusay Mahmoud", "UTF-8");
     String email = "email="+URLEncoder.encode("qmahmoud@javacourses.com", "UTF-8");
    // send the encoded message
     out.println(name+"&"+email);
     out.close();
     BufferedReader in
       = new BufferedReader(new InputStreamReader(connection.getInputStream()));
     String line;
    while ((line = in.readLine()) != null) {
       System.out.println(line);
     }
     in.close();
   }
}
