安卓日记——http中的get和post方法

get和post可以简单的理解为get将参数写在url后，而post不是

可以看到下面代码，传给Asyntask的url是不同的

get和post都是比较耗时的，所以最好放在Asyntask里的doinbackground里

Asyntask的参数改为

（String, Void, Void）

然后在 Asyntask对应的}后添加（以post为例）

.execute("http://192.168.23.1:8080/st/society_login.jsp");

把参数传给doinbackground

button1是post方法的实现

button2是get方法的实现

post方法要将

URLConnection改为<pre name="code" class="java">HttpURLConnection

否则不能<pre name="code" class="java">setRequestMethod("POST");

button1.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				new AsyncTask<String, Void, Void>(){
					
					@Override
					protected Void doInBackground(String... arg0) {
						URL url;
						try {
							url = new URL(arg0[0]);
							HttpURLConnection connection=(HttpURLConnection) url.openConnection();
							connection.setDoInput(true);
							connection.setDoOutput(true);
							connection.setRequestMethod("POST");
							
							OutputStreamWriter osw=new OutputStreamWriter(connection.getOutputStream(),"utf-8");
							BufferedWriter bw=new BufferedWriter(osw);
							bw.write("st_id=1001&pass=aa");
							bw.flush();
							
							
							InputStream is=connection.getInputStream();
							InputStreamReader isr=new InputStreamReader(is,"utf-8");
							BufferedReader br=new BufferedReader(isr);
							String line;
							while ((line=br.readLine())!=null) {
								System.out.println(line);
								
							}
							br.close();
							isr.close();
							is.close();
							
						} catch (MalformedURLException e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
						} catch (IOException e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
						}
						
						
						return null;
					}
					
				}.execute("http://192.168.23.1:8080/st/society_login.jsp");

				
				
			}
		});
		button2.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				new AsyncTask<String, Void, Void>(){

					@Override
					protected Void doInBackground(String... arg0) {
						URL url;
						try {
							url = new URL(arg0[0]);
							URLConnection urlConnection=url.openConnection();
							InputStream is=urlConnection.getInputStream();
							InputStreamReader isr=new InputStreamReader(is,"utf-8");
							BufferedReader br=new BufferedReader(isr);
							String line;
							while ((line=br.readLine())!=null) {
								System.out.println(line);
								
							}
							br.close();
							isr.close();
							is.close();
							
						} catch (MalformedURLException e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
						} catch (IOException e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
						}
						
						
						return null;
					}
					
				}.execute("http://192.168.23.1:8080/st/society_login.jsp?st_id=1001&pass=aa");

				
				
			}
		});
