Description
Description:
When using QHttpPart to build multipart/form-data requests, the Content-Disposition header is missing in Qt 6.8.2, while it works correctly in Qt 6.5.3 and 6.7.2. This appears to be a regression introduced in Qt 6.8.2.
Environment:
OS: macOS 14.6.1 (23G93)
clang version 19.1.7
Qt Versions Tested:
✅ 6.5.3 (works)
✅ 6.7.2 (works)
❌ 6.8.2 (broken)
My code:
void uploadFile(QString user, QString filename, QString md5, int size, QFile* file) { /* Content-Disposition */ QHttpPart part; QString disp = QString("form-data; " "user=\"%1\"; " "filename=\"%2\"; " "md5=\"%3\"; " "size=%4") .arg(user, filename, md5, QString::number(size)); part.setHeader(QNetworkRequest::ContentDispositionHeader, disp); /// BUG: not work on Qt 6.8.2 /* Content-Type */ part.setHeader(QNetworkRequest::ContentTypeHeader, "application/octet-stream"); part.setBodyDevice(file); QHttpMultiPart* multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType); multiPart->append(part); QNetworkRequest request; request.setUrl(QString("http://XXXX.XX")); QNetworkReply* reply = NetworkTool::getNetworkManager()->post(request, multiPart); multiPart->setParent(reply); ... /* Send */ ... }
I tried sending SVG images to the server.
Works in Qt 6.5.3/6.7.2 as shown in sample output below:
--boundary_.oOo._VwEORf0wIk84+Ljoc7T7mJiPCJnvummn Content-Disposition: form-data; user="123123"; filename="histogram.svg"; md5="111111111111"; size=955 Content-Type: application/octet-stream <?xml version="1.0" encoding="UTF-8"?> <svg width="512" height="512" fill="none" version="1.1" viewBox="0 0 512 512" xmlns="http://www.w3.org/2000/svg"> ... </svg> -{-}boundary_.oOo._VwEORf0wIk84+Ljoc7T7mJiPCJnvummn{-}-
But in Qt 6.8.2 the Content-Disposition header is completely missing:
