It's probably the usual garbage-collection problem: your
QHttpMultiPart is being destroyed before the network manager tries to
send the data to the network, then it reads freed data.
Here's a fragment of some code that works:
multipart =
QtNetwork.QHttpMultiPart(QtNetwork.QHttpMultiPart.FormDataType)
for name, value in fields.iteritems():
part = QtNetwork.QHttpPart()
part.setHeader(QtNetwork.QNetworkRequest.ContentTypeHeader,
'text/plain; charset=utf-8')
part.setHeader(QtNetwork.QNetworkRequest.ContentDispositionHeader,
'form-data; name="%s"' % name)
part.setBody(value.encode('utf-8'))
multipart.append(part)
filepart = QtNetwork.QHttpPart()
filepart.setHeader(QtNetwork.QNetworkRequest.ContentTypeHeader,
file['type'])
filepart.setHeader(QtNetwork.QNetworkRequest.ContentDispositionHeader,
'form-data; name="%s"; filename="%s"' % (file['name'], file['filename']))
filepart.setBodyDevice(file['device'])
multipart.append(filepart)
reply = manager.post(request, multipart)
# Hook multipart to the reply so that it sticks around for the lifetime
of the request
multipart.setParent(reply)
