HTTP響應的OAuth錯誤

Question

@Override 
protected Boolean doInBackground(Void... params) { 
    // TODO Auto-generated method stub 


     HttpClient httpclient = new DefaultHttpClient(); 
     Log.d("HTTP","Exe"); 
     String sw=Sign(token); 
     Log.d("HTTP","Exe"); 

     HttpPost httpPost; 
     Log.d("HTTP","Exec"); 
     httpPost = new HttpPost(sw); 
     Log.d("HTTP","Execute"); 

     HttpResponse response; 
     try 
     { 

      Log.d("HTTP","Executed"); 
//**THIS IS WHERE IT STOPS EXECUTION** 

       response = httpclient.execute(httpPost); // the request executes 
       Log.d("HTTP","Executed"); 
       HttpEntity entity = response.getEntity(); 
       InputStream is = entity.getContent(); 
       BufferedReader reader = new BufferedReader(new InputStreamReader(is, "utf-8"), 256); 
       StringBuilder sb = new StringBuilder(); 
       String line = null; 
       while ((line = reader.readLine()) != null) sb.append(line); 
       String result = sb.toString(); 
       is.close(); 
       Log.d("HTTP",result); 
       String responseBody = EntityUtils.toString(((HttpResponse) response).getEntity()); 
       retString=responseBody; 
       Log.d("HTTP",result); 

      } 

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


      //return null; 

     return null; 
    }

簽署的密鑰（SW）是https://api.dropbox.com/1/shares/dropbox/a.jpg?oauth_consumer_key=2f2y1dyuqhp58ek&oauth_token=wz27t6thob0fbxl&oauth_nonce=1340648163&oauth_timestamp=1340648163&oauth_signature_method=HMAC-SHA1&oauth_version=1.0&oauth_signature=bo%2F5zuowvX%2Fcjy5uPP5ZPjUiP64%3D%0A

我沒有以http ..

了豐富的經驗，因爲 httpPost =新的HttpPost（sw）; 正常工作，這是否意味着Base String Signature是正確的？

或我錯過了什麼？

Answer 1

看來這與OAuth錯誤無關。根據以下日誌聲明，似乎你沒有在http post url中設置主機。
