InvalidArgument: POST requires exacty one file upload per request

mucai

I try to use QHttpMultiPart to post a file but there is a following errr:

<Error>
<Code>InvalidArgument</Code>
<Message>POST requires exactly one file upload per request.</Message>
<ArgumentValue>0</ArgumentValue>
<ArgumentName>file</ArgumentName>
</Error>

The following are my codes:
QFile *file = new QFile(filePath);
file->open(QIODevice::ReadOnly);
QHttpPart filePart;
filePart.setHeader(QNetworkRequest::ContentTypeHeader, typeHeader);
filePart.setHeader(QNetworkRequest::ContentDispositionHeader, upload_content_disposition);
filePart.setRawHeader("FileName", fileName);
filePart.setRawHeader("file", filePath);
filePart.setBodyDevie(file);

QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);
file->setParent(multiPart);
multiPart->append(filePart);

QNetworkRequest request(qurl);
mQTManager->post(request, multiPart);

Do you have any advice?

Thanks

QHttpMultipart is very buggy and I think it uses a very different specification so it always fail.

I have a note in "QNetworkAccessManager":http://qt-project.org/doc/qt-4.8/qnetworkaccessmanager.html entitled "POST with QIODevice" , you might find it useful.

If you are trying to "upload" using a Form, use "FormPost":http://www.tuckdesign.com/sources/Qt , it saved me a lot of time when I was coding for "libqsendspace":https://github.com/Code-ReaQtor/libqsendspace . You just need to modify their source code or you may use the code from my github site ("qsendspace" folder).
