Using QHttp in a QDS service

Hi all,

In a standalone application, I can successfully use QHttp to communicate with a backend server.
Now I'm trying to publish this communication as a QDS service. Basically, the same code (signal connecting, same slots etc) was transfered to the server.

The service uses a utility class that executes this QHttp object successfully and retrieves the information I want, though it generates two requestFinished signals.
The first is right after http->request() and returns a "" string
The second takes a bit longer (as expected) and returns the desired information.

I have tried placing the following after http->request():

Code:

---

while (!reponseRetrieved) {
    loop.processEvents(QEventLoop::AllEvents); // with other parameter variations
}

---

But the signal is still executing twice. I'm trying to synchronize the http so the service returns the information correctly.

Any reason for this behavior?

First requestFinished signal is probably the result of QHttp::setHost and in that case is perfectly normal. You need to use the request id to look for requests you're monitoring.

Hum, that would explain only one done signal, though the actual response should really have requestID = 2 (for the first service call)?

If that's the normal behavior than ok by me. I'm just curious why wouldn't the setHost count as a request itself when running the same code in a standalone application?

Maybe the signal was firing before you made the signal/slot connection? Hard to guess without seeing the actual code. I'm sure the behaviour is coherent on all platforms.

Hum, probably. But since the actual purpose is to be in a service, and checking with stateChanged confirmed that only one request is actually sent to the backend server, I'm cool with that.
Will improve request ID management. Thanks for the info.
