Crate google_oauth

Google-Oauth

A server-side google oauth2 verification library for rust.

Installation

This library is hosted on crates.io

[dependencies]
google-oauth = "1"

Usage

The Library provides API to verify id_token from Google.

Example: Blocking

// With blocking client, we don't need async runtime.
use google_oauth::Client; // This is a blocking client

let client_id = "The client_id generated from google...";
let client = Client::new(client_id); // now we get this.

let data = client.validate_id_token("The id_token you want to validate").unwrap();

// if ok, we get the data...
let sub = data.sub.as_str();
println!("Hello, user (sub = {}) now is online", sub);

Example: Async

// When you use async client, remember to add a async runtime (e.g, `tokio` or `async_std`)
use google_oauth::AsyncClient; // This is a async client

// It works just like the blocking client, excepts the verification step.

#[tokio::main]
async fn main() {
    let client_id = "...";
    let client = AsyncClient::new(client_id);

    /// note: use `await`
    let data = client.validate_id_token("The id_token you want to validate").await.unwrap();

    // it `unwrap()` is ok, we get the data ...
    println!("Hello, user (sub = {}) now is online", sub);
}
