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://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();

    }

}--

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;
}
