如何使用傑克遜庫（這個寧靜的.NET Web API）

Question

這是的.NET Web API URI是http://sampleurlapi...../userRegistration/

如果使用POST方法JSON設置標題和內容類型的機器人

try { 
       JSONObject jsonobj = new JSONObject(); 
       jsonobj.put("ResNo", -1); 
       jsonobj.put("DateCreated", "12-12-2015"); 
       JSONArray jsonArray = new JSONArray(); 
       for (int i = 0; i < finalSelectedArrayList.size(); i++) { 
        JSONObject resobject = new JSONObject(); 
        resobject.put("StySK", finalSelectedArrayList.get(i).getParentSK()); 
        resobject.put("TwrSK", finalSelectedArrayList.get(i).getTwrSK()); 
        resobject .put("BlkSK", finalSelectedArrayList.get(i).getBlkSK()); 
        resobject.put("FlrSK", finalSelectedArrayList.get(i).getFlrSK()); 
        resobject.put("AptSK", finalSelectedArrayList.get(i).getAptSK()); 
        resobject.put("IsDftUt", finalSelectedArrayList.get(i).getDefaultKey()); 
        resobject .put(resobject); 
       } 

//使網絡服務連接

HttpPost request = new HttpPost(url); 
      request.setHeader("Accept", "application/json"); 
      request.setHeader("Content-type", "application/json"); 
      // Build JSON string 

      StringEntity entity = new StringEntity(jsonobj.toString()); 
      request.setEntity(entity); 
      // Send request to service 
      DefaultHttpClient httpClient = new DefaultHttpClient(); 
      HttpResponse response = httpClient.execute(request); 
      // Get the status of web service 
      BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); 

      //If the result is returned as NULL, then make the validation to fail. 
      if ((strValidationResult = rd.readLine()) == null) { 
       strValidationResult = Boolean.FALSE.toString(); 
      } 

我已經寫了JSON就像這些。

如何寫json使用jackson並設置content-type和accept類型？

感謝您的提前！

Answer 1

The Request set header like this problem is service side only 
HttpPost request = new HttpPost(url); 
request.setHeader("Accept", "application/json"); 
request.setHeader("Content-type", "application/json"); 

Answer 2

i don't know what you ask but i consumed .net service this way 


method calling here   
int i = getconnect(email, pass); 


get connect method 


public Integer getconnect(String id, String pass) { 
     String result = null; 
     String i = null; 
     int statusCode=400; 
     String r="0"; 
     String m=""; 
     int s=0; 

      try { 

       HttpPost request = new HttpPost(url2); 
       request.setHeader("Accept", "application/json"); 
       request.setHeader("Content-type", "application/json"); 

       // Build JSON string 
       JSONStringer item = new JSONStringer() 
         .object() 
         .key("password").value(pass) 
         .key("username").value(email) 
         .endObject(); 
       StringEntity entity = new StringEntity(item.toString()); 

       request.setEntity(entity); 

       // Send request to WCF service 
       DefaultHttpClient httpClient = new DefaultHttpClient(); 
       HttpResponse response = httpClient.execute(request); 
       HttpEntity entity1 = response.getEntity(); 
       InputStream stream = entity1.getContent(); 
       r = convertStreamToString(stream); 
        JSONObject jo = new JSONObject(r); 
       s= (Integer) jo.get("Flag"); 
       Log.d("json result is:", r); 
      statusCode = response.getStatusLine().getStatusCode(); 

      } catch (Exception e) { 
       e.printStackTrace(); 

      Log.d("error", "code"+0); 
     } 
     return s; 
    } 
    public static String convertStreamToString(InputStream is) { 
     BufferedReader reader = new BufferedReader(new InputStreamReader(is)); 
     StringBuilder sb = new StringBuilder(); 
     String line = null; 
     try { 
      while ((line = reader.readLine()) != null) { 
       sb.append(line + "\n"); 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
      try { 
       is.close(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
     return sb.toString(); 
    }
