#Rust 🦀 – Learning HTTP GET and POST requests in Rust, and yes this is a “🌐What’s my IP” demo 😄

Hi !

Yes, I’m starting to use OpenAI services in with Rust. However, before getting here, I spent some time learning how to work with HTTP Requests in Rust.

There seems to be several libraries that can help. I found several examples using [https://docs.rs/reqwest/0.6.2/reqwest/], so I decided to use this one.

A classic example to do this, is to perform an HTTP GET request to the following url, to get our public IP Address.

https://httpbin.org/ip

And hey, the code is super simple
