Description
Recently my youtube uploading code stopped working, which relied on a basic multipart
void QNetworkTools::uploadYoutubeVideo(QFile &file, const QString &title, QString description, const QStringList &tags) { /* Create Request */ QNetworkRequest request; { // There may be some useless parameters in here. They were only added as I was // trying to figure out if I could use them to make the upload work setUri("https://www.googleapis.com/upload/youtube/v3/videos"); addUrlParameter("part", "snippet,status"); addUrlParameter("client_id", OAuth2.client_id()); addUrlParameter("redirect_uri", OAuth2.redirect_uri()); addUrlParameter("scope", OAuth2.scope()); addUrlParameter("notifySubscribers", "False"); addUrlParameter("onBehalfOfContentOwner", ""); addUrlParameter("onBehalfOfContentOwnerChannel", ""); request.setUrl(uri()); request.setRawHeader("Authorization", "Bearer " + OAuth2.access_token().toUtf8()); } /* Video Settings */ QHttpMultiPart* multiPart = new QHttpMultiPart(QHttpMultiPart::MixedType); QString body; { QHttpPart jsonPart; jsonPart.setHeader(QNetworkRequest::ContentTypeHeader,QVariant("application/json")); body = QString(R"( "kind": "youtube#video", "snippet": { "title": "%1", "description": "%2", "tags": ["%3"], "categoryId": "27" }, "status": { "privacyStatus": "public", "license": "creativeCommon" }, "notifySubscribers": "False" )").arg(title, description.remove("\""), tags.join("\",\"")).remove(" "); jsonPart.setBody(body.toUtf8()); multiPart->append(jsonPart); } /* Video File */ QHttpPart videoPart; { if (file.open(QIODevice::ReadOnly)) { videoPart.setBodyDevice(&file); } videoPart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("video/*")); videoPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("Slug")); multiPart->append(videoPart); } QNetworkReply *reply = m_NetworkAccessManager.post(request, multiPart); QEventLoop waitForUpload; connect(reply, &QNetworkReply::finished, &waitForUpload, &QEventLoop::quit); waitForUpload.exec(); disconnect(reply, &QNetworkReply::finished, &waitForUpload, &QEventLoop::quit); }
After much confusion, I stumbled across two posts:

This one leads you to believe that google may have disabled multipart uploading. However upon further searching,
https://github.com/Elringus/UnityGoogleDrive/issues/30#issuecomment-436971836
states the following:
_Looks like Google has made validation of the multipart bodies more strict. I've had to manually compose the body, preserving all the new lines and spaces, before it finally accepted the request. Multipart uploads in the latest release should work fine now: https://github.com/Elringus/UnityGoogleDrive/releases/tag/v0.22-alpha
_
This looks like a bug unfortunately introduced by google.
