How to connect via API?

[SGaist]

What version of Qt are you using ?

@Mikeeeeee said in How to connect via API?:

I installed everything in MaintenanceTool

Terrible idea

[Mikeeeeee]

I use Qt 5.12.2

[SGaist]

Then try again with the latest version of the 1.0 series.

[Mikeeeeee]

I downloaded openssl-1.0.2r. There is no bin folder. No .exe files. No libeay32.dll. What to do with it?

[Mikeeeeee]

I downloaded libeay32.dll ssleay32.dll and put them to the executable file and the project, but it still does not work.

[SGaist]

Still the same error or another one ?

[Mikeeeeee]

Same error: TLS initialization failed

[SGaist]

Did you check whether you can connect to another https resource and if it triggers the same error ?

[Mikeeeeee]

Not check. I don't know what other resource to connect to.

How to fix this error?

[Pablo J. Rogina]

@Mikeeeeee you may try a JSON testing site with secure connections, like https://jsonplaceholder.typicode.com

i.e. https://jsonplaceholder.typicode.com/todos/1 will return:

{
  "userId": 1,
  "id": 1,
  "title": "delectus aut autem",
  "completed": false
}

@Pablo-J.-Rogina said in How to connect via API?:

https://jsonplaceholder.typicode.com/todos/1

Tried to send to this address and got an old error.

[Mikeeeeee]

And if you sent"http://json placeholder.typecode.com/todos/1" it works. Why https doesn't work?

[SGaist]

Just to be sure add this to your code:

qDebug() << QSslSocket::supportsSsl();
qDebug() << QSslSocket::sslLibraryBuildVersionString();
qDebug() << QSslSocket::sslLibraryVersionString();

[Mikeeeeee]

qDebug returns:
qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed
false
"OpenSSL 1.0.2p 14 Aug 2018"

Are you sure you put the OpenSSL 1.0 dlls in the right folder ? Without mixing them with another version of OpenSSL.

[Mikeeeeee]

Sure. Here is the contents of the folder:

hi
I wonder if it also wants libssl32.dll ?
