I am using SwiftNIO with the Connect Proxy based on the official example (swift-nio-examples/connect-proxy at main · apple/swift-nio-examples · GitHub ).
I was able to create proxy server and its working. but I'm not able to print the https url params and its body.
I don't know how i will be able to print that out.

I have tried to look into the source code but I don't have a lot of experience with these frameworks and wasn't exactly sure where to look.

Thanks very much!

The parameters are available here: swift-nio-examples/ConnectHandler.swift at main · apple/swift-nio-examples · GitHub

i have tried the above but unable to log url params. and my ConnectHandler is the same as mentioned in example.
For example
if i search https://jsonplaceholder.typicode.com/todos/1
then mentioned code print jsonplaceholder.typicode.com:443 not the full url.

That is expected. The URI for CONNECT requests only includes the host and port of the target but nothing else.
If you run curl with a proxy configured and in verbose mode you can see the headers that it sends:

 % curl -v --proxy "[::1]:8888" https://example.com/path/to/resource
*   Trying [::1]:8888...
* Connected to (nil) (::1) port 8888 (#0)
* allocate connect buffer
* Establish HTTP proxy tunnel to example.com:443
> CONNECT example.com:443 HTTP/1.1
> Host: example.com:443
> User-Agent: curl/7.86.0
> Proxy-Connection: Keep-Alive

You can see here that it only send CONNECT example.com:443 HTTP/1.1 but /path/to/resource is not included.

there will be something that we can do to find the /path/to/resource when we try https://example.com/path/to/resource
