[Help] in Setting up EFI Shell in QEMU to allow for HTTP Requests

Greetings,
I want to create an UEFI App with internet connection.

Before I start developing the code, I wanted to make sure my setup is working properly so that the app can make http requests.
To that end, I spent the last days trying to make the `http` command work in the EFI Shell launched inside QEMU.
I can get the ping command to work properly, but calling:
http httpbin.org/get
Always returns:
Unable to open http protocol on `eth0` - Unsupported
Unable to download the file `/get` on `eth0` - Unsupported

This is my startup.nsh script to configure the interface:
connect
ifconfig -r eth0
ifconfig -s eth0 dhcp
ifconfig -l eth0

These were my different attempts at invoking Qemu properly:
        -netdev user,id=mynet0,hostfwd=tcp::8080-:80 -device e1000,netdev=mynet0 \
        -netdev user,id=user.0 -device e1000,netdev=user.0 \
        -nic user,ipv6=off,model=e1000,mac=52:54:98:76:54:32 \

And following this guide<https://gist.github.com/extremecoders-re/e8fd8a67a515fee0c873dcafc81d811c> I tried to setup a tap, but no dice:
        -netdev tap,id=mynet0,ifname=tap0,script=no,downscript=no -device e1000,netdev=mynet0,mac=52:55:00:d1:55:01 \

Have you ever achieved this? What was your setup like?

Thank you for your time.

Are you sure you have the HttpDxe driver in your OVMF build?  Looks like 
you'd need to build with either -D NETWORK_HTTP_ENABLE or -D 
NETWORK_HTTP_BOOT_ENABLE.

See https://github.com/tianocore/edk2/blob/master/OvmfPkg/README for 
details on HTTPS.

Hello,

Yes that was exactly the problem, someone helped me solve it on StackOverflow: https://stackoverflow.com/questions/75452349/setting-up-the-efi-shell-in-qemu-to-allow-for-http-requests/75458138#75458138

I hadn't noticed those instructions in the readme though, thank you for that.

Cheers.
