简单代码如下：

1.Map<String, String> params = new HashMap<String, String>();  
   params.put("id", "11223");  
   params.put("nonce\_str", RandomStringUtils.randomNumeric(16));  
   params.put("message", "...aaaabc");  
   DefaultHttpClient httpclient = new DefaultHttpClient();  
//   HttpPost post = postForm(url, params);  
   HttpPost httpost = new HttpPost(url);  
   List<NameValuePair> nvps = new ArrayList<NameValuePair>();  
   Set<String> keySet = params.keySet();  
   for (String key : keySet) \{  
    nvps.add(new BasicNameValuePair(key, params.get(key)));  
   \}  
   try \{  
    httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF\_8));  
   \} catch (UnsupportedEncodingException e) \{  
    e.printStackTrace();  
   \}  
     
   HttpResponse response = httpclient.execute(httpost);  
   HttpEntity entity = response.getEntity();  
   String result = EntityUtils.toString(entity);  
   //释放链接  
   httpclient.getConnectionManager().shutdown();

2.HttpClient httpClient= new DefaultHttpClient();  
        HttpPost post = new HttpPost(DETECT\_URL);  
        HttpEntity resEntity = null ;  
        try \{  
            MultipartEntity mutiEntity = new MultipartEntity();  
            mutiEntity.addPart("api\_key", new StringBody("a", Charset.forName("UTF-8")));  
            mutiEntity.addPart("api\_secret", new StringBody("b", Charset.forName("UTF-8")));  
            mutiEntity.addPart("image\_file" , new FileBody(image\_file));  
            post.setEntity(mutiEntity);  
            HttpResponse response = httpClient.execute(post);  
            resEntity = response.getEntity();  
            if (resEntity != null) \{  
                String result = EntityUtils.toString(resEntity,"UTF-8");  
                return JSONObject.fromObject(result);  
            \}  
        \} catch(Exception e) \{  
            log.error("f出现异常  : "+e.getMessage() , e);  
            throw new Exception(e.getMessage() , e);  
        \}finally\{  
            //释放链接  
            httpClient.getConnectionManager().shutdown();  
        \}  
         
        return json ;
