CURL Request -> HTTP Post equivalent (solved)

[hypnomaki]

Hi,
I want to connect my QT-Project to a API.
the API CURL call is :
"curl -X POST -u username:password https://my.fastbill.com/api/1.0/api.php"

I Only want to use QT-Libs thats why i tried it with following Code
@
QNetworkAccessManager* manager = new QNetworkAccessManager(this);
QNetworkRequest request;
QByteArray postData="";
QUrl Adresse("https://my.fastbill.com/api/1.0/api.php");
request.setUrl(Adresse);
network_reply = manager->post(request,postData);
@

I can connect to the server this way but the reply alsways is "wrong userdata".
So i tried various ways to fix this for example:
@
Adresse.setUserName("username");
Adresse.setPassword("password");
Adresse.setQuery("username:password");
Adresse.setUserInfo("username:password");
@

But not a single one of them works.
Can you tell me what I'm doing wrong or how to make this Call with the Help of QT-Libs?

Hi and welcome to devnet,

Unless I misunderstood, you might be interested by "this":http://doc.qt.io/qt-5/qnetworkaccessmanager.html#authenticationRequired

Hope it helps

Fastbill expects the Content-Type to be set to application/xml And the POST body to be an XML request. You are not sending a valid XML request, hence the error message about the body. (It also accepts a Json formatted request)

@ChrisW67,
Thats not the problem. If I send the equal Curl command via my Linux Terminal as told in the api ->
"curl -X POST -u username:apikey https://my.fastbill.com/api/1.0/api.php"
the response is that there’s actually no Content. But the login worked!
And exactly this result is what I want to accomplish with QT-Libs.

@SGaist, thx I will have a look at it!

ALL,

I now solved the problem....
Its about the Signal written in the documentation - ChrisW67 sent us the link to.

There are 2 Possibility’s:

1. Do it via the Signal

2. Set a Header to the QNetworkRequest:
   @QString concatenated = username + ":" + password;
   QByteArray data = concatenated.toLocal8Bit().toBase64();
   QString headerData = "Basic " + data;
   request.setRawHeader("Authorization", headerData.toLocal8Bit());@

Thx again and a happy new year!
