Check PayPal Access Token Expiration

See more PayPal Examples

Checks to see if the PayPal access token expired. Rust

// Note: Requires Chilkat v9.5.0.64 or greater.

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// In the example linked here: PayPal OAuth2 Token,
// we fetched a PayPal access token and saved it to a JSON file.
// We also recorded the current date/time.
// Load this JSON file and compare the current date/time with the fetch date/time
// and the "expires_in" value to see if the token is expired.

let json = chilkat::JsonObject::new();
if json.load_file("qa_data/tokens/paypal.json").is_err() {
    println!("Failed to load access key json file.");
    return;
}

// Get the current date/time.
let date_time = chilkat::DateTime::new();
let b_local_time = false;
let dt_now = date_time.get_as_unix_time(b_local_time) as i32;

// Get the access token create date/time
let dt_create = json.int_of("tokenCreateTimeUtc");

// Find out how many seconds have elapsed.
let num_seconds = dt_now - dt_create;

// Get the expires_in value from the JSON.
let expires_in = json.int_of("expires_in");

println!("token age (in seconds) = {}", num_seconds);
println!("expires_in = {}", expires_in);

// If the token expired, or if it will expire in 5 minutes or less,
// get another token.
if num_seconds < (expires_in - 300) {
    println!("The token is not yet expired.  No need to fetch another.");
    return;
}

println!("Time to fetch a new access token...");

// Get another token..
// See the example at Get PayPal OAuth2 Token
// to get another token..
