Загрузка многопользовательского файла Android с токеном доступа

Question

Я хочу отправить токен доступа как многостраничные данные вместе с файлом на php-сервер. Я написал следующий код, но он дает ошибку 401 Unauthorized. Я думаю, что не пропускаю access_token. Как это сделать?

Answer 1

Это зависит от конфигурации сервера. В общем случае, если вам нужно передать токен авторизации с помощью Http POST, его передать с заголовком setHeader. Вот мой фрагмент рабочего кода для многофакторной загрузки файлов.

HttpClient client = new DefaultHttpClient(); 
File file = new File(selectedImagePath); 
HttpPost post = new HttpPost(uploadUrl); 

post.setHeader("token", myAuthToken); 
post.setHeader("Content-type", "multipart/form-data; boundary=" + boundary); 
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE, 
        Constants.BOUNDARY, Charset.defaultCharset()); 

entity.addPart(Constants.MULTIPART_FORM_DATA_NAME, new FileBody(file)); 
post.setHeader("Accept", "application/json"); 
post.setHeader("Content-Type", "multipart/form-data; boundary=" + boundary); 

post.setEntity(entity); 

HttpResponse response = client.execute(post); 
HttpEntity httpEntity = response.getEntity(); 
Log.d("Response", EntityUtils.toString(httpEntity));

Рабочая копия Multipart загрузки изображений с помощью службы:

private MutipartImageUploadModel handleUploadAction(int tileId) { 
     String imageName = getTilesInUploadPath(this, fileId); 
     if (imageName == null) { 
      return null; 
     } 
     InputStream responseInputStream; 
     try { 
      File filesDir = getApplicationContext().getFilesDir(); 
      File imageFile = new File(filesDir, imageName); 
      HttpClient httpClient = new DefaultHttpClient(); 
      HttpContext localContext = new BasicHttpContext(); 
      double bytes = imageFile.length(); 
      HttpPost httpPost = new HttpPost(ServiceConstantInterface.URL_UPLOAD_IMAGE);   httpPost.setHeader(ServiceConstantInterface.Authorization_KEY, ServiceConstantInterface.Authorization_KEY_VALUE); 
      httpPost.setHeader("SessionKey", new SharedPrefDataSupplier(this).getmSessionKey()); 
      MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create(); 
      entityBuilder.addPart("file_name", new FileBody(imageFile)); 
      entityBuilder.addPart("file_id", new StringBody(String.valueOf(fileId))); 
      entityBuilder.addPart("SessionKey", new StringBody(new SharedPrefDataSupplier(getApplicationContext()).getmSessionKey())); 
      HttpEntity entity = entityBuilder.build(); 
      httpPost.setEntity(entity); 
      HttpResponse response = httpClient.execute(httpPost, localContext); 
      StatusLine statusLine = response.getStatusLine(); 
      if (statusLine.getStatusCode() == 200) { 
       responseInputStream = response.getEntity().getContent(); 
       if (responseInputStream != null) { 
        Reader reader = new InputStreamReader(responseInputStream); 
        Gson gson = new GsonBuilder().create(); 
        MutipartImageUploadModel wResponse = gson.fromJson(reader, MutipartImageUploadModel.class); 
        Log.i(TAG, "Response " + wResponse); 
        try { 
         reader.close(); 
         responseInputStream.close(); 
        } catch (Exception e) { 
         e.printStackTrace(); 
        } 
        return wResponse; 
       } 
      } else { 
       Log.i(TAG, "Server responded with status code: " + statusLine.getStatusCode()); 
      } 
     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); 
     } catch (ClientProtocolException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 

     } 
     return null; 
    }

Если вы планируете отправить некоторые заголовки, маркеры доступа, печенье, то вы должны установить его в запрос свойств части, как:

// Open a HTTP connection to the URL 
      conn = (HttpURLConnection) url.openConnection(); 
      conn.setDoInput(true); // Allow Inputs 
      conn.setDoOutput(true); // Allow Outputs 
      conn.setUseCaches(false); // Don't use a Cached Copy 
      conn.setRequestMethod("POST"); 
      conn.setRequestProperty("Connection", "Keep-Alive"); 
      conn.setRequestProperty("ENCTYPE", "multipart/form-data"); 
      conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); 
      conn.setRequestProperty("file", fileName); 
      **conn.setRequestProperty("COOKIE_NAME_OR_TOKEN", mToken);**
