QNetworkAccessManager - How to send “PATCH” request

Question

I am trying to send a "PATCH" request to my firebase application.As far as I read QNetworkManager doesn't support "Patch" request.

How can I send "PATCH" request ?

Answer 1

So we are clear that there is no method in QNetworkAccessManager named "patch" Therefore I have used "sendCustomRequest" but with QBuffer. Because QNetworkManager requires a QIODevice object.

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";

try:

QNetworkAccessManager* manager = new QNetworkAccessManager();
QNetworkRequest request("http://<domain>/<path>/");
QHttpMultiPart* multipart = new QHttpMultiPart();
//... Add your data in multipart
manager->sendCustomRequest(request, "PATCH", multipart);
