使用JSON在http POST後發生奇怪的響應

Question

我在做什麼應該是一個簡單的http帖子，其中包含一個json字符串作爲http正文。

？

所有看起來不錯，除了響應本身 - 當我把它變成一個字符串它回來看起來很奇怪（不是文本）。我怎樣才能以純文本得到這個？或者我在帖子中做錯了什麼，以獲得此回覆？ （注 - 如果我在POST過程中排除的cookies我從服務器獲取純HTML回瓦特/有效的「拒絕訪問」消息）

的完整代碼此解決方案是低於

public class BaseHttpService { 
    public ResponseAndCookies doHttpPostWithUrlWithJson(String url, String key, CookieStore cookies) { 
     try { 
      StringEntity se = new StringEntity("{\"filters\":true}"); 
      se.setContentType("text/xml"); 
      se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); 

      HttpPost httpost = new HttpPost(url); 
      httpost.setEntity(se); 

      httpost.setHeader("Accept", "application/json"); 
      httpost.setHeader("Content-Type", "application/json"); 

      return executeHttpRequest(httpost, cookies); 
     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    public ResponseAndCookies executeHttpRequest(HttpRequestBase http, CookieStore cookieStore) { 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpResponse response; 
     String result = ""; 

     if (cookieStore != null) { 
      ((DefaultHttpClient) httpclient).setCookieStore(cookieStore); 
     } 

     try { 
      response = httpclient.execute(http); 

      HttpEntity entity = response.getEntity(); 

      if (entity != null) { 
       InputStream instream = entity.getContent(); 
       result = convertStreamToString(instream); 
      } 

     } catch (ClientProtocolException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     List<Cookie> cookies = ((DefaultHttpClient) httpclient).getCookieStore().getCookies(); 
     CookieStore postCookieStore = ((DefaultHttpClient) httpclient).getCookieStore(); 

     ResponseAndCookies x = new ResponseAndCookies(); 
     x.setCookies(cookies); 
     x.setResponse(result); 
     x.setCookieStore(postCookieStore); 

     httpclient.getConnectionManager().shutdown(); 

     return x; 
    } 

    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(); 
    } 
}

你試過閱讀一個UTF-8字符串與平臺編碼它似乎。 找出返回的響應的內容編碼並使用該編碼轉換爲字符串。

讓我知道如果你想用2行代碼替換上面的代碼。我爲您提供了一個已經處理cookies並轉換內容的項目。
