@SGaist am I get the correctly contentTypeheader With that link ?

[zhmh]

And am I use contentTypeHeader correctly?

[SGaist]

Did you check what the endpoint you are sending requests to requires ?

[VRonin]

Can you show us an example of valid request to your API? Maybe using curl?

P.S.
Qt tutorials from https://www.bogotobogo.com should be avoided, they are of very low quality and sometimes encourage toxic patterns in code.

@SGaist @VRonin I send post request with postman in google chrome
I set header Content-Type:"application/json"
in body section I choose raw
and data:"122,2019/02/21,10:54:31"
data is successfully posted to the API and I can see it on the URL

I change my code :

 QNetworkRequest request(QUrl("http://site.com/api/PtData/"));
request.setRawHeader("Content-Type", "application/json");
   QByteArray data("102,2018/02/16,19:17:23");
    QNetworkAccessManager nam;
    QNetworkReply *reply = nam.post(request, data);

I do not get any errors, but when I check the URL, the data is not post(set)on it

Except that what you send is not valid JSON.

@SGaist but I post the same format data that I use in postman

POST /api/PatData/ HTTP/1.1
Host: site.com
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: c31beda7-12bf-d5b8-4945-88895d0727a0

"102,2019/02/21,23:31:21"

[SGaist]

You should check the data sent using postman.

[zhmh]

I checked the C code in postman the data format must be :

QByteArray data("\"185,2019/02/22,10:59:21\"");

Finally it's post successfuly :-/
