android http协议post请求方式
http://lrc-1986.iteye.com/blog/868799
方式一：HttpPost（import org.apache.http.client.methods.HttpPost
Java代码 
[java]
代码如下：
private Button button1,button2,button3;
private TextView textView1;
button1.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
//URLַ
// String uriAPI = "http://www.dubblogs.cc:8751/Android/Test/API/Post/index.php";
String uriAPI = "http://172.20.0.206:8082//TestServelt/login.do";
/*建立HTTP Post连线*/
HttpPost httpRequest =new HttpPost(uriAPI);
//Post运作传送变数必须用NameValuePair[]阵列储存
//传参数 服务端获取的方法为request.getParameter("name")
List <NameValuePair> params=new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name","this is post"));
try{
//发出HTTP request
httpRequest.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));
//取得HTTP response
HttpResponse httpResponse=new DefaultHttpClient().execute(httpRequest);
//若状态码为200 ok
if(httpResponse.getStatusLine().getStatusCode()==200){
//取出回应字串
String strResult=EntityUtils.toString(httpResponse.getEntity());
textView1.setText(strResult);
}else{
textView1.setText("Error Response"+httpResponse.getStatusLine().toString());
}
}catch(ClientProtocolException e){
textView1.setText(e.getMessage().toString());
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
textView1.setText(e.getMessage().toString());
e.printStackTrace();
} catch (IOException e) {
textView1.setText(e.getMessage().toString());
e.printStackTrace();
}
}
});
[/java]
方式二：HttpURLConnection、URL(import java.net.HttpURLConnection;import java.net.URL;import java.net.URLEncoder;)
Java代码
[java]
private void httpUrlConnection(){
try{
String pathUrl = "http://172.20.0.206:8082/TestServelt/login.do";
//建立连接
URL url=new URL(pathUrl);
HttpURLConnection httpConn=(HttpURLConnection)url.openConnection();
////设置连接属性
httpConn.setDoOutput(true);//使用 URL 连接进行输出
httpConn.setDoInput(true);//使用 URL 连接进行输入
httpConn.setUseCaches(false);//忽略缓存
httpConn.setRequestMethod("POST");//设置URL请求方法
String requestString = "客服端要以以流方式发送到服务端的数据...";
//设置请求属性
//获得数据字节数据，请求数据流的编码，必须和下面服务器端处理请求流的编码一致
byte[] requestStringBytes = requestString.getBytes(ENCODING_UTF_8);
httpConn.setRequestProperty("Content-length", "" + requestStringBytes.length);
httpConn.setRequestProperty("Content-Type", "application/octet-stream");
httpConn.setRequestProperty("Connection", "Keep-Alive");// 维持长连接
httpConn.setRequestProperty("Charset", "UTF-8");
//
String name=URLEncoder.encode("黄武艺","utf-8");
httpConn.setRequestProperty("NAME", name);
//建立输出流，并写入数据
OutputStream outputStream = httpConn.getOutputStream();
outputStream.write(requestStringBytes);
outputStream.close();
//获得响应状态
int responseCode = httpConn.getResponseCode();
if(HttpURLConnection.HTTP_OK == responseCode){//连接成功
//当正确响应时处理数据
StringBuffer sb = new StringBuffer();
String readLine;
BufferedReader responseReader;
//处理响应流，必须与服务器响应流输出的编码一致
responseReader = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), ENCODING_UTF_8));
while ((readLine = responseReader.readLine()) != null) {
sb.append(readLine).append("\n");
}
responseReader.close();
tv.setText(sb.toString());
}
}catch(Exception ex){
ex.printStackTrace();
}
}
