qnetworkaccessmanager

I can download from the server but I can't upload to it. It uploads the file but it's an empty file. This is basically what I'm doing: QString filename="Data.txt"; QFile file( filename ); file.open(QIODevice::ReadWrite); file.write("HELLO") ; QUrl urlup("ftp://127.0.0.1/file.txt"); urlup.setPassword("123"); urlup.setUserName("user"); urlup.setPort(21); QNetworkAccessManager *nam = new QNetworkAccessManager; QNetworkRequest requp(urlup); nam->put(requp,&file); file.close(); but it's not working; just uploads an empty file. user3220907 Instead of 127.0.0.1 use localhost Instead of setPort append

This question already has an answer here : Qt signal slot connection - QNetworkAccessManager (1 answer) Closed 4 years ago . I was checking some simple examples of using QNetworkAccessManager and I found this (Assuming that manager is a QNetworkAccessManager: QNetworkRequest request; request.setUrl(QUrl("http://www.someserver.com")); QNetworkReply *reply = manager->get(request); connect(reply, SIGNAL(readyRead()), this, SLOT(slotReadyRead())); connect(reply, SIGNAL(error(QNetworkReply::NetworkError)), this, SLOT(slotError(QNetworkReply::NetworkError))); connect(reply, SIGNAL(sslErrors(QList

I'm trying to use Qt to download the html code from the following url: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=nucleotide&cmd=search&term=AB100362 this url will re-direct to www.ncbi.nlm.nih.gov/nuccore/27884304 I try to do it by following way, but I cannot get anything. it works for some webpage such as www.google.com, but not for this NCBI page. is there any way to get this page?? QNetworkReply::NetworkError downloadURL(const QUrl &url, QByteArray &data) { QNetworkAccessManager manager; QNetworkRequest request(url); QNetworkReply *reply = manager.get(request); QEventLoop loop;

I am trying to send a "PATCH" request to my firebase application.As far as I read QNetworkManager doesn't support "Patch" request. How can I send "PATCH" request ? So we are clear that there is no method in QNetworkAccessManager named "patch" Therefore I have used "sendCustomRequest" but with QBuffer. Because QNetworkManager requires a QIODevice object. QString destination=""; currentNode.replace(QString("/").append(latestNode),""); destination .append(host) .append(currentNode) .append(".json"); QString jsonString=QString(QString("{").append("\"").append(latestNode).append("\"").append(":")

It seems that QNetworkAccessManager does not handle missing files retrieved by ftp if the ftp server requires authentication. The situation is this: I'm downloading multiple files from the same ftp server that requires username and password. I successfully download a few files then send a GET for a file that does not exist. That request reports failure. I then send a GET request for a file that should be valid. That request never emits a finished signal or error. Qt 4.7.4 Please help! This is driving me nuts. I think that if I can somehow reset the ftp backend, this problem might be solvable.

I am trying to connect my application with a web service and here ,a user suggested to send custom headers back to my application. I am using this code void Coonnec::serviceRequestFinished(QNetworkReply *reply) { QByteArray bytes = reply->readAll(); if (reply->error() != QNetworkReply::NoError) { qDebug() << "Reply error: " + reply->errorString(); } else { qDebug() << "Uploaded: " + QDateTime::currentDateTime().toString(); qDebug() << reply->rawHeaderList(); } reply->close(); bytes.clear(); reply->deleteLater(); } from php i send this header header('XAppRequest-Status: complete'); When running

I need to exchange data with server which requires local certificate (.crt file). I try this: loginRequest = QNetworkRequest(QUrl("https://somesite.com/login")); QSslConfiguration sslConf = loginRequest.sslConfiguration(); QList<QSslCertificate> certs = QSslCertificate::fromPath(Preferences::certificatePath()); qDebug() << certs.first().issuerInfo(QSslCertificate::Organization); // prints name sslConf.setLocalCertificate(certs.first()); qDebug() << "is valid " << sslConf.localCertificate().isValid(); // true qDebug() << "is null " << sslConf.localCertificate().isNull(); // false qDebug() <<
