Android HTTP Communication

1. Server-side
The simplest server-side receive code that directly prints the data across both *

 PackageCn.servlet;ImportJava.io.IOException;ImportJavax.servlet.ServletException;ImportJavax.servlet.annotation.WebServlet;ImportJavax.servlet.http.HttpServlet;ImportJavax.servlet.http.HttpServletRequest;ImportJavax.servlet.http.HttpServletResponse;/** * Servlet Implementation class Myservlet */@WebServlet("/myservlet") Public  class myservlet extends httpservlet {    Private Static Final LongSerialversionuid =1L/** * @see httpservlet#httpservlet () */     Public Myservlet() {Super();//TODO auto-generated constructor stub}/** * @see httpservlet#doget (httpservletrequest request, httpservletresponse response) */    protected void Doget(HttpServletRequest request, httpservletresponse response)throwsServletexception, IOException {//TODO auto-generated method stub        //Insist on calling the Post method         This. DoPost (Request, response); }/** * @see httpservlet#dopost (httpservletrequest request, httpservletresponse response) */    protected void DoPost(HttpServletRequest request, httpservletresponse response)throwsServletexception, IOException {//TODO auto-generated method stub        //Data acquisitionString name = Request.getparameter ("Name"); String age = Request.getparameter ("Age");//Print dataSYSTEM.OUT.PRINTLN (name);    System.out.println (age); }}

2. Client
First we customize a thread

publicclass Thread1 extends Thread//数据来自布局的文本编辑框String name ;    String age;    String url;    publicThread1(String name, String age,String url){        this.name=name;        this.age=age;        this.url=url;    }

1) Implementation of the Get method

 Public voidDoget () {Try{places of special attention of the//get methodurl=url+"? name="+urlencoder.encode (Name,"Utf-8")+"&age="+age;//Convert to URL objectURL Httpurl =NewURL (URL);//Get Connection objectHttpURLConnection conn = (httpurlconnection) httpurl.openconnection ();//Set Transfer methodConn.setrequestmethod ("GET"); Conn.setreadtimeout ( the);//Read input streamBufferedReader br =NewBufferedReader (NewInputStreamReader (Conn.getinputstream ())); StringStr; StringBuffer SB =NewStringBuffer ();//Put SB in separate                 while((Str=br.readline ())! =NULL) {Sb.append (Str); }        }Catch(Malformedurlexception e) {//TODO auto-generated catch blockE.printstacktrace (); }Catch(IOException e) {//TODO auto-generated catch blockE.printstacktrace (); }    }

2) The implementation of the Post method

 Public void DoPost(){Try{URL Httpurl =NewURL (URL);            HttpURLConnection conn = (httpurlconnection) httpurl.openconnection (); Conn.setrequestmethod ("POST"); Conn.setreadtimeout ( the);//Note This is Conn.getoutputstream, not new, so it can be linked .OutputStream out=conn.getoutputstream (); String content ="Name="+name+"&age="+age; out. Write (Content.getbytes ()); BufferedReader br =NewBufferedReader (NewInputStreamReader (Conn.getinputstream ()));            String str; StringBuffer SB =NewStringBuffer (); while((Str=br.readline ())! =NULL) {sb.append (str); }        }Catch(Malformedurlexception e) {//TODO auto-generated catch blockE.printstacktrace (); }Catch(IOException e) {//TODO auto-generated catch blockE.printstacktrace (); }    }

Which method is executed in the Run method is used in the appropriate way

@Override    publicvoidrun() {        // TODO Auto-generated method stub        super.run();    doGet();//      doPost();    }

3) The layout of the client input data is simple, two edit text boxes and a button

private EditText etName,etAge;    private Button btnReg;

4) button click event

 btnReg.setOnClickListener(new OnClickListener() {            publicvoidonClick(View arg0) {                // TODO Auto-generated method stub                //把ip地址改为自己目前的                "http://192.168.191.1:8080/serve/ss";                new Thread1(etName.getText().toString(), etAge.getText().toString(), url).start();            }        });    }
