Multiple QNetworkRequests (post) with QNetworkNetworkAccessManager in a loop

[yeye_olive]

I do not understand all the details of your code, but something caught my attention. The line

p->mReply = p->mManager->post(req, postReq);

p->mReply = p->mManager->post(req, postReq);

overwrites the SyncPrivate's mReply member every time you send a request. Since all the requests made in the loop seem to go through the same Sync instance, I suppose that after the loop, mReply points to the last reply. Then, in Sync::replyFinished(), you always deal with that last reply, even if the slot is probably called for several of them. Here is a suggestion: instead of connecting to the QNetworkReply's finished() signal, consider connecting to QNetworkAccessManager::finished(QNetworkReply *) instead; that way, you get a pointer to the reply in the slot, right where you need it.
