我想在谷歌驱动器的根目录（所以我没有包含 id 字段）创建文件夹，但我收到错误代码 400，解析错误。我的代码：

void googled::createfolder(QNetworkReply* reply){
    QUrl url("https://www.googleapis.com/drive/v2/files");

    QByteArray data = reply->readAll();
    //qDebug() << data;
    QString x = getValue(data,"access_token");
    QString y = "Bearer " + x;
    m_n = new QNetworkAccessManager;
    QObject::connect(m_n, SIGNAL(finished(QNetworkReply *)),
    this, SLOT(foldercreateSlot(QNetworkReply *)));
    QByteArray arr;
    QNetworkRequest request;
    QString str;
    str += QString("{");
    str += "\r\t";
    str += QString("\"title\": \"SMP\"");
    str += "\r\n";
    str += "\r\t";
    str += QString("\"mimeType\": \"application/vnd.google-apps.folder\"");
    str += "\r\n";

    str += QString("}");
    request.setUrl(url);
    qDebug() << str;
    request.setRawHeader("Content-Type","application/json");
    request.setRawHeader("Authorization",y.toLatin1());
    m_n->post(request,arr);
}

您不会在请求正文中包含任何边界和文件内容。一个适当的身体如下所示。

POST /upload/drive/v2/files?uploadType=multipart HTTP/1.1
Host: www.googleapis.com
Authorization: your_auth_token
Content-Type: multipart/related; boundary="foo_bar_baz"
Content-Length: number_of_bytes_in_entire_request_body

--foo_bar_baz
Content-Type: application/json; charset=UTF-8

{
  "title": "My File"
}

--foo_bar_baz
Content-Type: image/jpeg

blob data

--foo_bar_baz--

它已经在Drive SDK 的出色文档中进行了解释。在阅读可用文档之前，请不要提问。
