Function quarenta::login

pub async fn login<'_, '_, '_, '_>(
    client: &'_ Client, 
    username: &'_ String, 
    password: &'_ String, 
    referrer: &'_ String
) -> Result<JsonValue, Box<dyn Error>>

Attempts to login to ArcGIS Online.

Arguments

• client - A reqwest client. If None, this method creates a new one. It is advisable to create one and reuse it.
• username - The username
• password - The password
• referrer - A referrer string that will need to be used with the resulting token

Return

The function returns a JSON result which, if Ok, contains either values for token, expires, and ssl or an error object. An invalid username/password combination results in the error object.

Errors

The function's result will be either Ok or Err. If Err, it's probably because the login request went wrong (e.g. no network connectivity), not because of a bad username or password.

Examples

let reqwest_client = reqwest::Client::new();
let login_result: Result<T,Box<dyn Error>> = login(&reqwest_client, &username, &password, &referrer).await;
match login_result {
   Ok(token_response) => {
       match token_response["token"].as_str() {
           Some(token) => {
               println!("Token: {}...", &token[..20]);
               println!("Expiry: {}", token_response["expires"]);
               println!("SSL only: {}", token_response["ssl"]);
           },
           None => {
               println!("Login returned but was not successful: {}", token_response);
           }
       }
   },
   Err(err) => {
       println!("Something went wrong while calling login: {:?}", err);
   },
}
