Android通过http协议POST传输方式

在这里做个简单是总结和实现:

-----------------------------------------------------------------------------------------------------------------------


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

     //URLַ

            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();

    }

}--

Android通过http协议POST传输方式

下面有好几种的实现方式:

1。

public Map<String, Object> CreateNote(int albumId, String title,
02         String remark) {
03     String noteId = "";
04     Map<String, Object> map = new HashMap<String, Object>();
05     try {
06         HttpParams parms = new BasicHttpParams();
07         parms.setParameter("charset", HTTP.UTF_8);
08                 HttpConnectionParams.setConnectionTimeout(parms, 8 1000);
09                 HttpConnectionParams.setSoTimeout(parms, 8 1000);
10         HttpClient httpclient = new DefaultHttpClient(parms);
11         HttpPost httppost = new HttpPost(ConfigHelper.CreateUri);
12         httppost.addHeader("Authorization", mToken);
13         httppost.addHeader("Content-Type""application/json");    
14         httppost.addHeader("charset", HTTP.UTF_8);
15  
16         JSONObject obj = new JSONObject();
17         obj.put("title", title);
18         obj.put("categoryId", mCategoryId);
19         obj.put("sourceUrl", GetSourceUri());
20  
21         JSONArray arr = new JSONArray();
22  
23         arr.put(DateFormat.format("yyyyMM",Calendar.getInstance(Locale.CHINA)));       
24         obj.put("tags", arr);
25         obj.put("content", remark);
26         httppost.setEntity(new StringEntity(obj.toString(), HTTP.UTF_8));
27         HttpResponse response;
28         response = httpclient.execute(httppost);
29         int code = response.getStatusLine().getStatusCode();
30         if (code == ConstanDefine.ErrorCode.SuccOfHttpStatusCode) {
31             String rev = EntityUtils.toString(response.getEntity());
32             obj = new JSONObject(rev);
33             noteId = obj.getString("id");
34             map.put("return_code""0");
35             map.put("content", rev);           
36         }
37     catch (Exception e) {
38         if (map.containsKey("return_code")) {
39             map.remove("return_code");
40         }
41         map.put("return_code""1");       
42     }
43     return map;
44 }

2。

public static String post1(String message)
    {
        String uriAPI = HTTP_PORT ;
        HttpPost httpRequest = new HttpPost(uriAPI);
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("input", message));
        try {
 
            httpRequest.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
            org.apache.http.HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);
 
            if (httpResponse.getStatusLine().getStatusCode() == 200) {
                String strResult = EntityUtils.toString(httpResponse.getEntity());
                return strResult;
            } else {
                System.out.println(httpResponse.getStatusLine().getStatusCode());
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
