Android Facebook-SDK多部分/表單數據上傳獲得“無效的OAuth訪問令牌”

Question

我使用HttpCilent 4.0.1上傳圖片，但出現HTTP 400錯誤，這樣的錯誤消息，請Plz有人幫助我。

{“錯誤”：{“類型”：“ OAuthException”，“消息”：“無效的OAuth訪問令牌。”}}

我的代碼是...

private void uploadPicture( ) throws ParseException, IOException {
    HttpClient httpclient = new DefaultHttpClient();
    httpclient.getParams( ).setParameter( CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1 );

    HttpPost httppost = new HttpPost( "https://graph.facebook.com/me/photos" );
    File file = new File( sdpicturePath );

    // DEBUG
    Log.d( "TSET", "FILE::" + file.exists( ) ); // IT IS NOT NULL
    Log.d( "TEST", "AT:" + fbAccessToken ); // I GOT SOME ACCESS TOKEN

    MultipartEntity mpEntity  = new MultipartEntity( );
    ContentBody cbFile        = new FileBody( file, "image/png" );
    ContentBody cbMessage     = new StringBody( "TEST TSET" );
    ContentBody cbAccessToken = new StringBody( fbAccessToken );

    mpEntity.addPart( "access_token", cbAccessToken );
    mpEntity.addPart( "source",       cbFile        );
    mpEntity.addPart( "message",      cbMessage     );        

    httppost.setEntity( mpEntity );

    // DEBUG
    System.out.println( "executing request " + httppost.getRequestLine( ) );
    HttpResponse response = httpclient.execute( httppost );
    HttpEntity resEntity = response.getEntity( );

    // DEBUG
    System.out.println( response.getStatusLine( ) );
    if (resEntity != null) {
      System.out.println( EntityUtils.toString( resEntity ) );
    } // end if

    if (resEntity != null) {
      resEntity.consumeContent( );
    } // end if

    httpclient.getConnectionManager( ).shutdown( );
} // end of uploadPicture( )

您收到的訪問令牌需要進行URL解碼。 我使用了URLDecoder.decode（）和MultiPartEntity（HttpMultipartMode.STRICT）;
