Android通过http协议POST传输方式
Android通过http协议POST传输方式如下：
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();
??? }
?? }
????????
??????? });
方式二：HttpURLConnection、URL(import java.net.HttpURLConnection;import java.net.URL;import java.net.URLEncoder;)
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();
??? }
?? }
