嘗試將文件上傳到Google雲端存儲時出現FileNotFoundException

Question

我正嘗試將圖像從Android上傳到雲端存儲。我正在關注如何使用JSON API將文件上傳到Google雲端存儲的this official guide。這裏是我的代碼

private class uploadImage extends AsyncTask<File, Void, String> { 

    File file = mPhotoFile; 

    private String delimiter = "--"; 

    @Override 
    protected void onPreExecute() { 
     Toast.makeText(getActivity(), mPhotoFile.getPath(), Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    protected String doInBackground(File... params) { 


     try { 
      URL url = new URL("https://www.googleapis.com/upload/storage/v1/b/backend-images/o?uploadType=media&name=myObject?key=my_key"); 
      HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); 

      urlConnection.setRequestMethod("POST"); 
      urlConnection.setChunkedStreamingMode(0); 
      urlConnection.setRequestProperty("Content-Type", "image/jpeg"); 
      urlConnection.setRequestProperty("Content-Length", String.valueOf(mPhotoFile.getPath().getBytes().length)); 
      urlConnection.setRequestProperty("Authorization", "my_key"); 
      urlConnection.setDoOutput(true); 
      urlConnection.setDoOutput(true); 


      OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream()); 
      InputStream responseStream = new BufferedInputStream(urlConnection.getInputStream()); 
      BufferedReader responseStreamReader = new BufferedReader(new InputStreamReader(responseStream)); 

      out.write(("Content-Type: image/jpeg\r\n").getBytes()); 
      out.write(("Content-Length: " + String.valueOf(mPhotoFile.getPath().getBytes().length)).getBytes()); 
      out.write("\r\n".getBytes()); 
      out.write(mPhotoFile.getPath().getBytes()); 
      out.write("\r\n".getBytes()); 

      String line = ""; 
      StringBuilder stringBuilder = new StringBuilder(); 

      while((line = responseStreamReader.readLine()) != null) { 
       stringBuilder.append(line).append("\n"); 
      } 

      String response = stringBuilder.toString(); 

      Log.i("CloudStorage", response); 
     } catch (IOException e) { 
      e.printStackTrace(); 
      return e.getMessage(); 
     } 

     return "Everything was a success"; 
    } 


} 

我使用的公共API訪問方法和附加的API密鑰像the guide says I could鏈接請求授權

錯誤

如果這是客戶端或服務器端的問題，我毫無頭緒

Answer 1

我在做了一些更改後纔開始工作。我得到401未經授權的錯誤代碼，這意味着我沒有權限訪問存儲桶。

因此，我不附加查詢參數key=api_key，我附加access_token=auth_token來授權請求​​。

然後，我添加了allUsers權限給我的存儲桶（使其公開給大家寫和讀），它的工作。
