OAuth client implementing the OAuth 2.0 and OpenID Connect protocols for Microsoft identity platform

Purpose built as OAuth client for Microsoft Graph and the graph-rs-sdk project. This project can however be used outside graph-rs-sdk as an OAuth client for Microsoft Identity Platform or by using graph-rs-sdk.

For async:

toml graph-oauth = "1.0.0" tokio = { version = "1.25.0", features = ["full"] }

For blocking:

toml graph-oauth = "1.0.0"

See the project on GitHub.

Supported Authorization Flows

Microsoft OneDrive and SharePoint

• Token Flow
• Code Flow

Microsoft Identity Platform

• Authorization Code Grant
• Authorization Code Grant PKCE
• Open ID Connect
• Implicit Grant
• Device Code Flow
• Client Credentials
• Resource Owner Password Credentials

For more extensive examples and explanations see the OAuth Examples in the examples/oauth directory on GitHub.

```rust use graph_oauth::oauth::{AccessToken, OAuth};

fn main() { let mut oauth = OAuth::new(); oauth .clientid("") .clientsecret("") .addscope("files.read") .addscope("files.readwrite") .addscope("files.read.all") .addscope("files.readwrite.all") .addscope("offlineaccess") .redirecturi("http://localhost:8000/redirect") .authorizeurl("https://login.microsoftonline.com/common/oauth2/v2.0/authorize") .accesstokenurl("https://login.microsoftonline.com/common/oauth2/v2.0/token") .refreshtokenurl("https://login.microsoftonline.com/common/oauth2/v2.0/token") .responsetype("code") .logouturl("https://login.microsoftonline.com/common/oauth2/v2.0/logout") .postlogoutredirect_uri("http://localhost:8000/redirect");

let mut request = oauth.build().authorization_code_grant();

// Opens the default browser.
let _ = request.browser_authorization().open();

// The access code will be appended to the url on redirect. Pass
// this code to the OAuth instance:
oauth.access_code("<ACCESS CODE>");

// Perform an authorization code grant request for an access token:
let response = request.access_token().send().await?;
println!("{response:#?}");

if response.status().is_success() {
    let mut access_token: AccessToken = response.json().await?;

    // Option<&JsonWebToken>
    let jwt = access_token.jwt();
    println!("{jwt:#?}");

    oauth.access_token(access_token);

    // If all went well here we can print out the OAuth config with the Access Token.
    println!("{:#?}", &oauth);
} else {
    // See if Microsoft Graph returned an error in the Response body
    let result: reqwest::Result<serde_json::Value> = response.json().await;

    match result {
        Ok(body) => println!("{body:#?}"),
        Err(err) => println!("Error on deserialization:\n{err:#?}"),
    }
}
