[java]  view plain  copy

 print ?

1. public static String getdata(String url, List<NameValuePair> params) {  
2.         String tag = "";  
3.         HttpClient httpClient = new DefaultHttpClient();  
4.         HttpPost post = new HttpPost(url);  
5.           
6.   
7.         try {  
8.             UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params,"utf-8");  
9.             post.setEntity(entity);  
10.             try {  
11.                 HttpResponse httpResponse = httpClient.execute(post);  
12.                 tag = "get string false";  
13.                 if (httpResponse.getStatusLine().getStatusCode() == 200) {  
14.                     HttpEntity entity2 = httpResponse.getEntity();  
15.                     tag=EntityUtils.toString(entity2);  
16.                     //tag = Decodtool.decodeUnicode(URLDecoder.decode(EntityUtils.toString(entity2, "uft-8"), "utf-8"));                      
17.                 }  
18.             } catch (ClientProtocolException e) {             
19.                 e.printStackTrace();  
20.             } catch (IOException e) {                 
21.                 e.printStackTrace();  
22.             }  
23.         } catch (UnsupportedEncodingException e) {            
24.             e.printStackTrace();  
25.         }  
26.         return tag;  
27.   
28.     }  

2.通过Gson解析：记得导入Gson包

[java]  view plain  copy

 print ?

1. public static void main(String[] args) {  
2.   
3.         String data = getdata();  
4.         System.out.println(parase(data).toString());  
5.     }  
6.   
7.     private static String getdata() {  
8.         String url = "http://192.168.2.171:9898/Service_Resource.ashx";   
9.         ArrayList<NameValuePair> params = new ArrayList<NameValuePair>();  
10.         params.add(new BasicNameValuePair("method", "GetAll"));  
11.         return NetworkUtil.getdata(url, params);  
12.     }  
13.   
14.     private static ArrayList<ResourceBean> parase(String data) {  
15.         Gson gson = new Gson();  
16.         JSONObject jsonObject = JSONObject.fromObject(data);  
17.         String datapart = jsonObject.getString("data");  
18.         Type type = new TypeToken<ArrayList<ResourceBean>>() {}.getType();  
19.         ArrayList<ResourceBean> resourcebeans = gson.fromJson(datapart, type);  
20.         return resourcebeans;  
21.     }
