QHttp to QNetworkAccessManager

[stevocz]

Hi.

I am changing QHttp to QNetworkAccessManager, but i can't find replacement for QHttp::request and QHttp::clearPendingRequests in QNetworkAccessManager

it is must work under QT4.6 and 5


thanks.

QNetworkAccessManager hands out QNetworkReply objects for each request that you are initiating.

See get(), head(), put(), post() for that.

QNetworkReply::abort() can be used to terminate any such request.

but i can't fint function witch returns unique identifier as QHttp::request

[anda_skoa]

As I said, each request is encapsulated by a request handler, an instance of QNetworkReply.

e.g. if you call QNetworkAccessManager::get() three times, each call returns a new instance of QNetworkReply, each of these objects signalling progress, error, when it is done, etc.

QList<QNetworkReply*> listOfRequests;

QList<QNetworkReply*> listOfRequests;

To copy to clipboard, switch view to plain text mode 

or:

static int reqId() { static int nextReq = 0; return ++nextReq; }
 
QHash<int, QNetworkReply*> listOfRequests;
 
listOfRequests.insert(reqId(), networReply);
 
int key = listOfRequests.key(networkReply);

static int reqId() { static int nextReq = 0; return ++nextReq; }

QHash<int, QNetworkReply*> listOfRequests;

listOfRequests.insert(reqId(), networReply);

int key = listOfRequests.key(networkReply);

To copy to clipboard, switch view to plain text mode 

etc.

True, but if you always want to abort all unfinished() requests at some point then you could also have a signal and connect that to each network reply object's deleteLater() slot.

Assuming that deleting a reply will abort it, but I think that is quite a safe guess.
