Problems with QNetwork | QNetworkAccessManager
-
i understand that QNetworkAccessManager is only calling handleResponse() when the request is finished so that presents a problem for self.xBoard = value["Name"] as when the request is finished the last entry in the array was "Små Sure" so that is what it will be set to :/ but how to fix it?
self.xBoard = "" self.nam = QtNetwork.QNetworkAccessManager() self.nam.connect(self.handleResponse) def doRequest(self): print("Run") print("#----------------------------------#") for key, value in self.board.items(): url = "http://" + value["ip"] self.xBoard = value["Name"] print("doRequests : " + self.xBoard) print("http://" + value["ip"]) req = QtNetwork.QNetworkRequest(QUrl(url)) self.nam.get(req) def handleResponse(self, reply): er = reply.error() if er == QtNetwork.QNetworkReply.NoError: bytes_string = reply.readAll() print("") print("#----------------------------------#") print("Result") print("#----------------------------------#") print(str(bytes_string, 'utf-8')) print("handleResponse : " + self.xBoard) self.board[self.xBoard]['Status'] = "Online" else: print("Error occured: ", er) print(reply.errorString()) self.board[self.xBoard]['Status'] = "Offline" -
Hi,
Don't use such a fixed variable for something that is dynamic like that. Either use the QNetworkReply returned by QNetworkAccessManager::get as a key to get the correct board name in the finished handler. Or set a dynamic proper on that reply object so you can grab back that information again when the request is finished.

Use setProperty/getProperty on your reply object to store the board name associated with the request.

-
Get the reply object returned by your QNAM instance, call the setProperty method. And in your slot, call the getProperty method on the reply object you get as parameter.

got it fixed! but why is QNetworkReply only replying once?

Since you did not post the whole code related to QNAM you are using, I can't answer.

@SGaist huh? the whole code is posted above?

It's incomplete. You have methods belonging to some class since they have self as first parameters and code that is just indented which may or may not belong to said class.

How fast are you generating these requests ?

Why are you using threads ?
QNAM is asynchronous so there's currently no need for threads especially in the first stage of development like that. -
