QNetworkRequest + How to add a json text in a PUT REST ?

mugunth

I am trying to use PUT request using QNetworkAccessManager. I need to know how to add body text to the PUT request.

Example of my PUT request url will be like this: example.com/member/14 (14 is member id to udpate)
I need to send the following body json string to update age of the member: { "age": 35} I could not find relevant qt documentation on how to pass the body text in REST requests.
Need some help on this. Thanks.

I haven't used the Qt's network stack that much, but what I read from the documentation something like the following should do it.

QString jsondata("{'age': 35}");
QNetworkAccessmanager mngr;

QNetworkRequest request("http://my.org/memebr/14");
request.setHeader(QNetworkRequest::ContentTypeHeader, QString("application/json"));

QNetworkReply* reply = mngr.put(request, jsondata.toUtf8());

Thanks for the reply.
I found issue with the single quote, but I made it working with slight modification in the jsondata creation as follows:

QString jsondata("{"age": 35}");

Also I could make it working by creating QJsonDocument for the variables and using it in the request as follows which was suitable for my case:

QVariantMap testMapData["age"] = 35;
QJsonDocument testJsonData = QJsonDocument::fromVariant(testmapdata);

QNetworkAccessmanager mngr;

QNetworkRequest request("http://my.org/memebr/14");
request.setHeader(QNetworkRequest::ContentTypeHeader, QString("application/json"));

QNetworkReply* reply = mngr.put(request, testJsonData.toJson());

Thanks again for your reply.
