QHttp RequestStarted does not even begin!

I set up my project, using QT += network

It's a static app and I included QtNetwork.

I made sure all the connections are connected... no problems there...

Code:

---

connect(http, SIGNAL(stateChanged(int)), this, SLOT(DisplayProgress(int)));
    connect(http, SIGNAL(requestFinished(int, bool)), this, SLOT(httpRequestFinished(int, bool)));
	connect(http, SIGNAL(requestStarted (int)), this, SLOT(httpRequestStarted(int)));
    connect(http, SIGNAL(dataReadProgress(int, int)), this, SLOT(updateDataReadProgress(int, int)));
    connect(http, SIGNAL(responseHeaderReceived(const QHttpResponseHeader &)), this, SLOT(readResponseHeader(const QHttpResponseHeader &)));

---

Neither get(), nor post() has any problem executing. But after that everything seems to go silent.

Like as if the signals aren't working at all.

I put logs everywhere, and not a single connected signal is being emitted. requestStarted doesn't even begin.

I made sure to follow the example in QHttp. I simply put up a GET for a PHP page online. I am online, firewall is off and everything (though it is vista).

Code:

---

void httpRequestStarted(int id){
   if(id == httpPostId){
		Log2("Started");
   } else if (id == httpGetId){
		Log2("Started");
   }
   Log2("Req Started");
}

---

But nothing is getting logged.
Apparently, either QtNetwork isn't working, or neither get nor post activates httpRequestStarted.

I declared http as a QHttp(this) (this being a QObject class).

The logs just stop here and here:

Code:

---

void cConnect::PostRead(QString data, const QString& siteurl, int encrypt){
	//data = Encrypt(data);
	httpRequestAborted = false;
	httpPostId = http->post(QUrl::toPercentEncoding(siteurl), data.toAscii());
}

---

This is for GET:

Code:

---

httpRequestAborted = false;
    httpGetId = http->get(QUrl::toPercentEncoding(Url), file);
	Log2("CC::Downloading File");

---

How can this be? I never declared a "Host" and I never get the signal for requestStart().

Are you running the event loop (for instance by calling QApplication::exec())?

In another file, I am running exec(), it's not a threaded app.

Also, I recently tried to see if simply setHost() is working, but even that doesn't work. No signals emitted.

However, signals are emitted in another test app i compiled.. So weird.

Also, when I immediately (not in any slot or signal), right after setHost, I typed:
http->errorString().toLocal8Bit().constData() for my log.
It says "Unknown Error". Shouldn't it say "No Error"?

At some point I did receive signals, but then they disappeared, I can't reproduce them.

Can you prepare a minimal compilable example reproducing the problem?

Well, when I opened the HTTP example inside my Qt directory, it wasn't working, some sort of missing dynamic link in qtnetwork.

Then, I took the code, put it in a different folder, compiled it myself, to see if my static compiled Qt works properly. And the HTTP downloader works nicely.

So my environment should be fine.

I even tried compiling http.exe as static, it worked fine too. It means that it must be something in my code maybe.

But I did everything, I triple checked all the codes, compared it with other http programs including your own. What are possible causes of signals not being emitted?

double post.

Ok I figured it out.

You were right the first time wysota.

See I do have an application running as app.exec(), but what I later meditated and figured out was, that if you have a program that works and then a function calls a new class (which does the HTTP work), then that new class returns, and then the function ends. And my problem was, I declared the class as a local object and it was on the local stack, so as soon as that function returned as well, the HTTP class never got a chance to run long enough to create signals etc... As soon as I changed the local object to a pointer object that runs throughout the main class, it worked perfectly.

Thanks.
