大致方法如下，没经过测试，稍微调试一下：



QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);



QHttpPart idPart;

QString id = "";

idPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"id\""));

idPart.setBody(id);

multiPart->append(idPart); // id



QHttpPart imagePart;

QString filePath = "image.jpg";

imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/jpeg"));

imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"attachment \"; filename=\"" + filePath + "\""));

QFile *file = new QFile(filePath);

file->open(QIODevice::ReadOnly);

imagePart.setBodyDevice(file);

file->setParent(multiPart); // Delete object with parent



multiPart->append(imagePart); // attachment



QUrl url("https://www.yingweiimage.com/service-film/v1/patient/study/dicom/upload");

QNetworkRequest request(url);



QNetworkAccessManager manager;

QNetworkReply *reply = manager.post(request, multiPart);

multiPart->setParent(reply); // Delete object with parent
