qnetworkaccessmanager

问题 I'm having some trouble with a Qt application; specifically with the QNetworkAccessManager class. I'm attempting to perform a simple HTTP upload of a binary file using the post() method of the QNetworkAccessManager. The documentation states that I can give a pointer to a QIODevice to post(), and that the class will transmit the data found in the QIODevice. This suggests to me that I ought to be able to give post() a pointer to a QFile. For example: QFile compressedFile("temp"); compressedFile

问题 Here is my code of Qt creator to send the data to PHP server and get the response. QNetworkAccessManager *manager = new QNetworkAccessManager(this); QNetworkAccessManager::connect(manager, SIGNAL(finished(QNetworkReply*)),this , SLOT(replyFinished(QNetworkReply*))); QNetworkRequest *request = new QNetworkRequest(QUrl("http://68.169.55.41/fss/verifylogindetails.php")); QByteArray postData =" {\"estate_id\":\"hsr\",\"emp_pin\":1234,\"emp_id\":\"santhosh\"}"; request->setRawHeader( "User-Agent"

问题 I've been having some issues trying to upload files to a server using QNetworkRequest. I've been using this link (http://qt-project.org/forums/viewthread/11361) mostly as a template, but am still getting POST errors (203 to be specific). Here is what I have so far. void MainWindow::processFile(){ QByteArray postData; //Look below for buildUploadString() function postData = mReport->buildUploadString(); QUrl mResultsURL = QUrl("http://" + VariableManager::getInstance()->getServerIP() + "

问题 I have used this code to sent the user name and a password to the server using POST Method. This returns me a reply,So how can I access the reply variable in the way that i can read the data sent from the server back to me ?? Used Code: void MainWindow::post(QString name, QString password) { QUrl serviceUrl = QUrl("http://lascivio.co/mobile/post.php"); QByteArray postData; QString s = "param1="+name+"&"; postData.append(s); s = "param2=" +password; postData.append(s); QNetworkAccessManager

问题 How do I setup a timeout when I do an http request? I have this code: { QNetworkRequest request; request.setUrl(QUrl("http://www.foo.com")); request.setRawHeader("User-Agent", USER_AGENT.toUtf8()); request.setRawHeader("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7"); request.setRawHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"); request.setRawHeader("Accept-Language", "en-us,en;q=0.5"); request.setRawHeader("Connection", "Keep-Alive"); reply = m

问题 I have a single QNetworkAccessManager object (as Qt docs recommend). However, I need to obtain a request from another thread, i.e. not the thread created the QNetworkAccessManager object. This questions has two aspects: As the functions ( get , post ... ) are not marked threadsafe I assume that I need to use a lock before calling them. But even if I make sure there are no 2 threads calling in parallel, issues could arise: So it could happen a QObject parent child relationship is set, but from

问题 I am using Qt 4.6.3 and the following not-working code QStringList userInfo; QNetworkRequest netRequest(QUrl("http://api.stackoverflow.com/1.1/users/587532")); QNetworkReply *netReply = netman->get(netRequest); // from here onwards not working netReply->waitForReadyRead(-1); if (netReply->isFinished()==true) {userInfo << do sth to reply;} return userInfo; as this function returns an empty QStringList, the app crashes. How to wait until the request has finished and then process the reply

问题 I am drawing map in BB10. The map is divided into tiles. At start user gives a longitude, latitude and zoom level and the map is shown at that co-ordinate. I get a single tile by doing a http request with QNetworkAccessManager. At first 7x5 tiles are downloaded. But the problem is when user starts panning in the screen really fast and continues to do so for sometimes then after user stopped panning the tiles are downloaded with a big delay. Each time user does panning some new tiles are
