Managing user sessions
For our users, we are going to have to enable them to log in. This means that we have to create an endpoint to check their credentials, and then generate a JWT to be returned back to the user in the frontend via the header in the response. Our first step is to define a login schema in the src/json_serialization/login.rs file with the following code:
use serde::Deserialize;
#[derive(Deserialize)]
pub struct Login {
pub username: String,
pub password: String
}
We have to remember to register it in the src/json_serialization/mod.rs file with the pub mod login; line of code. Once we have done this, we can build our login endpoint. We can do this by editing the src/views/auth/login.rs file we created in Chapter 3, Handling HTTP Requests, in the Managing views using the Actix-Web framework section, which declares our basic login view. This just returns a string.
Now, we can start refactoring this view by defining...
