android http协议post请求方式
方式一：HttpPost（import org.apache.http.client.methods.HttpPost
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 //URL?// 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(); } } });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();

} responseReader.close(); tv.setText(sb.toString()); } }catch(Exception ex){ ex.printStackTrace(); } }package alex.reader.ebook.bam;import java.io.IOException;import java.util.ArrayList;import java.util.HashMap;import java.util.Iterator;import java.util.List;import java.util.Map;import org.apache.http.HttpResponse;import org.apache.http.NameValuePair;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.HttpClient;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpGet;import org.apache.http.client.methods.HttpPost;import org.apache.http.client.params.HttpClientParams;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.message.BasicNameValuePair;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpConnectionParams;import org.apache.http.params.HttpParams;import org.apache.http.params.HttpProtocolParams;import org.apache.http.protocol.HTTP;import org.apache.http.util.EntityUtils;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.widget.EditText;public class SimpleClient extends Activity { private HttpParams httpParams;
