Function fetch_jwks

pub async fn fetch_jwks(oidc_url: &str) -> Result<Value>

Fetches the JSON Web Key Set (JWKS) from the specified OIDC provider URL.

This function sends a GET request to the .well-known/jwks endpoint of the provided OIDC URL to retrieve the JSON Web Key Set (JWKS), which contains the public keys used to verify OIDC tokens.

Arguments

• oidc_url - A string slice that holds the base URL of the OIDC provider.

Returns

• Result<Value> - A Result containing the JWKS as a serde_json::Value if successful, or an error if the fetch or parsing fails.

Errors

This function will return an error if:

• The HTTP request to fetch the JWKS fails
• The response cannot be parsed as valid JSON

Example

use git_oidc::fetch_jwks;
use color_eyre::eyre::Result;

#[tokio::main]
async fn main() -> Result<()> {
    let jwks = fetch_jwks("https://token.actions.githubusercontent.com").await?;
    println!("Fetched JWKS: {:?}", jwks);
    Ok(())
