Android客户端使用HttpURLConnection doGet与服务器数据交互简单示例

//安卓客户端发送请求
String strUrl="http://192.168.191.1:8080/trial/LoginServlet";
String result = null;
String readLine = null;
URL url1 = new URL(strUrl);
HttpURLConnection urlConn = (HttpURLConnection)url1.openConnection();
InputStreamReader in = new InputStreamReader(urlConn.getInputStream());
BufferedReader bufferReader = new BufferedReader(in);
while((readLine = bufferReader.readLine()) != null){
result += readLine;
}
in.close();
urlConn.disconnect();

//服务器端接收请求
package servlet;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class LoginServlet extends HttpServlet
{
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,IOException{
response.getOutputStream().print("admin");
}
}
