Question

根据Box API上传文件，这是curl命令：

curl https://upload.box.com/api/2.0/files/content \
      -H "Authorization: Bearer ACCESS_TOKEN" -X POST \
      -F attributes='{"name":"tigers.jpeg", "parent":{"id":"11446498"}}' \
      -F file=@myfile.jpg

我正在尝试使用QT上传图片，以下是我的代码：

QUrl url(QString::fromLatin1("https://upload.box.com/api/2.0/files/content"));
    auto* multipart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

    QHttpPart attributes;
    attributes.setHeader(QNetworkRequest::ContentDispositionHeader,
                    QLatin1String("form-data; name=\"attributes\""));
    QByteArray postData = QString::fromUtf8("{\"name\":\"%1\",\"parent\":{\"id\":\"%2\"}}").arg(QFileInfo(imgPath).fileName()).arg(id).toUtf8();
    attributes.setBody(postData);
    multipart->append(attributes);

    QFile* file = new QFile(imgPath);
    file->open(QIODevice::ReadOnly);
    file->setParent(multipart);

    QHttpPart imagepart;
    imagepart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/jpeg"));
    imagepart.setHeader(QNetworkRequest::ContentDispositionHeader,QVariant(QString::fromLatin1("form-data; name=\"image\";filename=\"%1\"").arg(QLatin1String(QFileInfo(imgPath).fileName().toUtf8()))));
    imagepart.setHeader(QNetworkRequest::ContentLengthHeader, file->size());    
    imagepart.setBodyDevice(file);
    multipart->append(imagepart);

    QNetworkRequest netRequest(url);
    netRequest.setHeader(QNetworkRequest::ContentTypeHeader, QLatin1String("multipart/form-data"));
    netRequest.setRawHeader("Authorization", QString::fromLatin1("Bearer {%1}").arg(d->o2->token()).toUtf8());
    d->reply = d->netMngr->post(netRequest, multipart);
    multipart->setParent(d->reply);

当我尝试上传图片时，出现错误提示

传输https://upload.box.com/api/2.0/files/content时出错- 服务器回复：错误的请求

我在做什么错了？

上载图片时Box API错误请求
