Save and use Oauth token

[subhrajyoti21]

Hey there, how do i get the token that has been generated after Oauth. I want to re use the token for the next set of requests to fetch emails sent to a specific email address. Also, how do i use the access token that has been generated. Below i have updated as per the documentation, but it does not seem to work.

Here's my code.

let secret = yup_oauth2::read_application_secret(std::path::Path::new("./secret.json"))
    .await
    .expect("./secret.json");

let auth = yup_oauth2::InstalledFlowAuthenticator::builder(
        secret,
        yup_oauth2::InstalledFlowReturnMethod::HTTPRedirect,
    )
    .build()
    .await
    .unwrap()

let mut hub = Gmail::new(
        hyper::Client::builder().build(hyper_rustls::HttpsConnector::with_native_roots()),
        auth,
    );

let result = hub
        .users()
        .messages_list("userId")
        .user_id("id”)
        .param("oauth_token", "<token>“)
        .param("access_token", "<token>“)
        .max_results(55)
        .doit()
        .await;

Please help.

This actually wasn't easily possible after the auth instance was handed to the hub.
I have fixed that to allow access to hub.auth, allowing to call hub.auth.token(), which is also done internally. It's available in gmail1-v2.0.9.

Thanks @Byron for the update

A follow up question on this -
How do i use the acces token retrieved from hub.auth.token()?
Basically, once the token is obtained a i should not require user approval to fetch their emails

It's important to set the correct scopes when obtaining authorization for these. Furthermore this library adds the token to each request depending on the required scopes for that request. There should be no need to add own parameters for authorization.
