Simple blocking HTTP GET request in Rust	2023-10-03 10:30:01 -0700	szabgab	true		reqwest blocking HTTP GET	POST change header get JSON send JSON

The reqwest crate provides functions for both asynchronous and blocking http requests. Although in most cases you'd probably want to use the asynch calls, using the blocking calls is simpler, so we start with that.

This is what we add to the Cargo.toml

{% include file="examples/simple-blocking-http-get-request/Cargo.toml" %}

And this is the code:

{% include file="examples/simple-blocking-http-get-request/src/main.rs" %}

This is the output (slightly reformatted to make it easier to read).
