QNetworkAccessManager - 如何发送"PATCH"请求

Question

我正在尝试向我的firebase应用程序发送"PATCH"请求.据我所知,QNetworkManager不支持"Patch"请求.

如何发送"PATCH"请求？

Answer 1

所以我们很清楚,QNetworkAccessManager中没有名为"patch"的方法因此我使用了"sendCustomRequest"而是使用了QBuffer.因为QNetworkManager需要QIODevice对象.

QString destination="";
currentNode.replace(QString("/").append(latestNode),"");
destination
        .append(host)
        .append(currentNode)
        .append(".json");
QString jsonString=QString(QString("{").append("\"").append(latestNode).append("\"").append(":").append("\"").append(str).append("\"").append(QString("}")));
QNetworkRequest request(destination);
request.setHeader(QNetworkRequest::ContentTypeHeader,
    "application/x-www-form-urlencoded");
qDebug()<<jsonString;
QBuffer *buffer=new QBuffer();
buffer->open((QBuffer::ReadWrite));
buffer->write(jsonString.toUtf8());
buffer->seek(0);
manager->sendCustomRequest(request,"PATCH",buffer);
qDebug()<<"posted";
