Uploading data to Tumblr API

  • Hi,

    I've been at this issue for a while and just cannot solve the issue. Using the HTTP POST Method, I wish to send images or audio files to Tumblr. I always seem to get 403 - Bad Request issue when doing this. Sending text is no issue.

    Code below is what I'm using:

    @void Control::uploadPhoto(QString stringy)
    qDebug() << stringy;
    QFile file("/home/user/MyDocs/Music/CuteTunes/Deluge.mp3");;
    QByteArray songArray;
    songArray = file.readAll();
    QUrl url1;
    url1.addEncodedQueryItem("email", "");
    url1.addEncodedQueryItem("password", "
    url1.addEncodedQueryItem("type", "audio");
    url1.addEncodedQueryItem("data", songArray);
    arrayPost = url1.encodedQuery();
    QNetworkRequest request;
    request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");
    reply3 =, songArray);
    connect(reply3, SIGNAL(metaDataChanged()), this, SLOT(errorCheck()));

    Any help with this will be greatly appreciated. I have spent a very long time attempting to solve this issue.--

    Thanks in advance,


  • Did you check the output of url1.encodedQuery() ?

  • It appears to be fine. Everything seems ok before the data is sent.

    Thanks for the help.

  • I'm not 100% sure, but as far as I remember, QNetworkRequest does not support file upload out of the box. You will have to prepare the data (wrapping into MIME headers etc.) yourself.
