Get a Google Drive Access Token using a .p12 Private Key

See more Google Drive Examples

Demonstrates how to get a Google Drive API access token using a .p12 private key. Rust

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

let g_auth = chilkat::AuthGoogle::new();

let pfx = chilkat::Pfx::new();
if pfx.load_pfx_file("qa_data/googleApi/ChilkatTest-5ba79ce39459.p12", "notasecret").is_err() {
    println!("{}", pfx.last_error_text());
    return;
}

if g_auth.set_p12(&pfx).is_err() {
    println!("{}", g_auth.last_error_text());
    return;
}

// Choose a scope.
g_auth.set_scope("https://www.googleapis.com/auth/drive");

// Request an access token that is valid for this many seconds.
g_auth.set_expire_num_seconds(3600);

// If the application is requesting delegated access:
// The email address of the user for which the application is requesting delegated access,
// then set the email address here. (Otherwise leave it empty.)
g_auth.set_sub_email_address("support@chilkatcloud.com");

g_auth.set_email_address("597922945226-00rb0ppfg0snd9jo6bhvd4v17jtj2d3a@developer.gserviceaccount.com");

// Connect to www.googleapis.com using TLS (TLS 1.2 is the default.)
// The Chilkat socket object is used so that the connection can be established
// through proxies or an SSH tunnel if desired.
let tls_sock = chilkat::Socket::new();
if tls_sock.connect("www.googleapis.com", 443, true, 5000).is_err() {
    println!("{}", tls_sock.last_error_text());
    return;
}

// Send the request to obtain the access token.
if g_auth.obtain_access_token(&tls_sock).is_err() {
    println!("{}", g_auth.last_error_text());
    return;
}

// Examine the access token:
println!("Access Token: {}", g_auth.access_token());
