How to connect via API?

[VRonin]

Qt uses OpenSSL to implement TLS and SSL

I installed everything in MaintenanceTool. Do I need to download additional OpenSSL?
If you need to install OpenSSL, then how to connect it to Qt?

What OS are you on ? My guess would be Windows.

[Mikeeeeee]

downloaded openssl-1.1.1b and put it in the folder with the executable file. Did not help.
In openssl-1.1.1b there is no libeay32.dll.

[Mikeeeeee]

There is a file e_os.h in the main folder of the library .

What version of Qt are you using ?

Terrible idea

[Mikeeeeee]

I use Qt 5.12.2

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?

@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
}
