Upload file to server via https
-
Hello,
i'm new in QT and i do not know how to send file to server. I have url like:
"https://www.example.com/?import=data=&DATA&",
where &DATA& is that file.i need something like:
request("https://www.example.com/?import=data=&DATA&"); respond = respond(); qDebug << respond;Is is possible?
@xbasista
From that URL I don't think it takes a file to upload. Rather I suspect you have to supply the data/content of the file where shown on the URL?You can use QNetworkReply *QNetworkAccessManager::get(const QNetworkRequest &request) to make the URL request you show.

Hi and welcome to devnet,
Beside the good points of my fellow, depending on your OS ensure that you have OpenSSL available as well.

Thanks,
@JonB you were right. I made simple http request as you wrote. It is working perfectly but when I put that application on another pc I get empty response (response = ""). It looks like application do not comunication to server. I tried add exception to windows firewall, turn off ativirus but it still not working.
Does anyone know where the problem might be?

You should add error handling to your code to see what happens.

@jsulm
I added to my code and i found out that on another pc is not openssl support [ QSslSocket::supportsSsl() ].
I read that https://stackoverflow.com/questions/20351155/how-can-i-enable-ssl-in-qt-windows-application and i think i need libeay32.dll and ssleay32.dll libs. The problem is i do not know where can i found that files? They shloud be in openSSL folder/bin but i don't have that folder.Output on build pc:
SslSupport: true SslLibraryBuildVersion: "OpenSSL 1.1.1g 21 Apr 2020" SslLibraryRuntimeVersion: "OpenSSL 1.1.1k 25 Mar 2021"Output on another pc:
SslSupport: SslLibraryBuildVersion: "OpenSSL 1.1.1g 21 Apr 2020" SslLibraryRuntimeVersion: -
I found out that:
"
For ssl 1.0.x (qt<5.12.4) you are likely missing libeay32.dll and ssleay32.dll.For ssl 1.1.x (qt>=5.12.4) binary compatibility broke (qt 5.12.4 released), so you might need libssl-1_1.dll and libcrypto-1_1.dll, and its dependencies capi.dll and dasync.dll.
"So i import libssl-1_1-x64.dll and libcrypto-1_1-x64.dll from my openssl and everything working.
Thanks
