//! # "It's not that hard" OAuth 2.0 //! //! OAuth 2.0 really isn't that hard, you know? //! //! Implementation of [RFC 6749](http://tools.ietf.org/html/rfc6749). //! //! `inth_oauth2` is on [Crates.io][crate] and [GitHub][github]. //! //! [crate]: https://crates.io/crates/inth-oauth2-async //! [github]: https://github.com/wfraser/inth-oauth2-async //! //! ## Providers //! //! Support for the following OAuth 2.0 providers is included: //! //! - Google //! - Web //! - Installed //! - GitHub //! - Imgur //! //! Support for other providers can be added by implementing the `Provider` trait. //! //! ## Token types //! //! The only supported token type is Bearer. Support for others can be added by implementing the //! `Token` trait. //! //! ## Examples //! //! ### Creating a client //! //! ``` //! use inth_oauth2_async::Client; //! use inth_oauth2_async::provider::google::Installed; //! //! let client = Client::new( //! Installed, //! String::from("client_id"), //! String::from("client_secret"), //! Some(String::from("redirect_uri")), //! ); //! ``` //! //! ### Constructing an authorization URI //! //! ``` //! # use inth_oauth2_async::Client; //! # use inth_oauth2_async::provider::google::Installed; //! # let client = Client::new(Installed, String::new(), String::new(), None); //! let auth_uri = client.auth_uri(Some("scope"), Some("state")); //! println!("Authorize the application by clicking on the link: {}", auth_uri); //! ``` //! //! ### Requesting an access token //! //! ```no_run //! # #[cfg(feature="reqwest-client")] { //! use std::io; //! use inth_oauth2_async::{Client, Token}; //! # use inth_oauth2_async::provider::google::Installed; //! # #[tokio::main] //! # async fn main() { //! # let client = Client::new(Installed, String::new(), String::new(), None); //! //! let mut code = String::new(); //! io::stdin().read_line(&mut code).unwrap(); //! //! let http = reqwest::Client::new(); //! let token = client.request_token(&http, code.trim()).await.unwrap(); //! println!("{}", token.access_token()); //! # } } //! ``` //! //! ### Refreshing an access token //! //! ```no_run //! # #[cfg(feature="reqwest-client")] { //! # use inth_oauth2_async::Client; //! # use inth_oauth2_async::provider::google::Installed; //! # #[tokio::main] //! # async fn main() { //! # let client = Client::new(Installed, String::new(), String::new(), None); //! # let http = reqwest::Client::new(); //! # let token = client.request_token(&http, "").await.unwrap(); //! let token = client.refresh_token(&http, token, None).await.unwrap(); //! # } } //! ``` //! //! ### Ensuring an access token is still valid //! //! ```no_run //! # #[cfg(feature="reqwest-client")] { //! # use inth_oauth2_async::Client; //! # use inth_oauth2_async::provider::google::Installed; //! # #[tokio::main] //! # async fn main() { //! # let client = Client::new(Installed, String::new(), String::new(), None); //! # let http = reqwest::Client::new(); //! # let mut token = client.request_token(&http, "").await.unwrap(); //! // Refresh token only if it has expired. //! token = client.ensure_token(&http, token).await.unwrap(); //! # } } //! ``` //! //! ### Using bearer access tokens //! //! ```no_run //! # #[cfg(feature="reqwest-client")] { //! # use inth_oauth2_async::Client; //! # use inth_oauth2_async::provider::google::Installed; //! use inth_oauth2_async::Token; //! //! # #[tokio::main] //! # async fn main() { //! # let oauth_client = Client::new(Installed, String::new(), String::new(), None); //! # let http = reqwest::Client::new(); //! # let token = oauth_client.request_token(&http, "").await.unwrap(); //! let request = http.get("https://example.com/resource") //! .bearer_auth(token.access_token()) //! .build(); //! # } } //! ``` //! //! ### Persisting tokens //! //! All token types implement `Serialize` and `Deserialize` from `serde`. //! //! ```no_run //! # #[cfg(feature="reqwest-client")] { //! # use inth_oauth2_async::Client; //! # use inth_oauth2_async::provider::google::Installed; //! # #[tokio::main] //! # async fn main() { //! # let http = reqwest::Client::new(); //! # let client = Client::new(Installed, String::new(), String::new(), None); //! # let token = client.request_token(&http, "").await.unwrap(); //! let json = serde_json::to_string(&token).unwrap(); //! # } } //! ``` #![warn( missing_docs, missing_debug_implementations, missing_copy_implementations, trivial_casts, trivial_numeric_casts, unused_extern_crates, unused_import_braces, unused_qualifications, variant_size_differences, )] #[macro_use] extern crate lazy_static; #[macro_use] extern crate serde_derive; pub mod token; pub mod provider; pub mod error; pub mod client; pub use token::{Token, Lifetime}; pub use client::{Client, ClientError};
