Question

我需要使用POST方法将文件上传到安全主机。这是我尝试的代码（文件可能包含文字内容，也可能是图片。如果是图片，我看here，我可以将ContentTypeHeader设置为QVariant("image/jpeg")所以我稍后会尝试。现在我试图上传一个纯文本文件）：

QUrl url(urlString); //typical secure host url - myhost.com/logs?key=<filename>&dsn=<some_dsn>&id=<id>&format=<format>

QNetworkRequest request(url);
QSslConfiguration config = request.sslConfiguration();
config.setPeerVerifyMode(QSslSocket::VerifyNone);
config.setProtocol(QSsl::TlsV1_0);

request.setSslConfiguration(config);
QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

QHttpPart imagePart;
imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("text/xml"));
imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"text\""));
QFile *file = new QFile(QString::fromStdString(fPathToFile));
file->open(QIODevice::ReadOnly);
imagePart.setBodyDevice(file);
file->setParent(multiPart); // we cannot delete the file now, so delete it with the multiPart

multiPart->append(imagePart);

QNetworkAccessManager manager;
QNetworkReply *reply = manager.post(request, multiPart);
connect(reply, SIGNAL(finished()), this, SLOT(onGetReply()));
connect(reply, SIGNAL(error(QNetworkReply::NetworkError)), SLOT(onError(QNetworkReply::NetworkError)), Qt::QueuedConnection);
multiPart->setParent(reply);

我在附加的插槽中有一个简单的qDebug，代码永远不会出现（当然文件也没有正确上传）。我无法理解为什么，它应该是成功还是失败，所以它至少应该来到其中一个插槽。我怀疑我必须正确设置证书。但我无法弄清楚如何。我去了here发布的解决方案，它要求输入密码，这里不需要密码，所以我不知道在那里提供什么。我运行了这个命令：

openssl s_client -showcerts -connect <myhost>:443 </dev/null

这是我得到的输出：

我无法理解如何从此输出中设置证书。如何将文件正确上传到我的主机？

P.S我还有与我的主机相对应的.pem文件，该文件是在浏览器中通过点击htts://myhost.com然后单击挂锁图标并从显示的弹出窗口下载文件获得的。这与上面获得的不同。

Qt通过POST上传文件到安全主机
