Crate ustc_cas 

a simple library for logging into USTC CAS System.

Usage

All you should do is call get_ticket. The function param service_url can be found from browser’s address bar when logging into CAS by hand. The returned ticket value can be used for further authentication specific to websites.

ustc_cas::get_ticket is an async function and requires a async runtime to execute. While ustc_cas::blocking::get_ticket, enabled by blocking feature, can not be used in an aysnc runtime. It with block the current thread before returning.

Example

use tokio::runtime::Builder;

 let runtime = Builder::new_current_thread()
    .enable_io()
    .enable_time()
    .build()
    .unwrap();

    let result = runtime.block_on(ustc_cas::get_ticket(
    "PB00000000",
    "12345678",
    "https://jw.ustc.edu.cn/ucas-sso/login",
 ));

 match result {
    Ok(s) => {
        println!("ticket: {s}");
    },
    Err(e) => {
        println!("Error: {e}");
    }
 }
