Google OAuth2 v3 userinfo (https://www.googleapis.com/oauth2/v3/userinfo)

See more Google APIs Examples

Demonstrates how to get the Google OAuth2 v3 userinfo.

Important: Make sure the OAuth2 access token included "profile" in the list of scopes.

Rust

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

// It is assumed we previously obtained an OAuth2 access token.
// This example loads the JSON access token file 
// originally obtained by this example: Get Google People API OAuth2 Access Token
// or refreshed by this example: Refresh Google People API OAuth2 Access Token

let json_token = chilkat::JsonObject::new();
if json_token.load_file("qa_data/tokens/googlePeople.json").is_err() {
    println!("Failed to load googleContacts.json");
    return;
}

let http = chilkat::Http::new();

// -------------------------------------------------------------------------------------
// Make sure the access token was obtained with "profile" included in the list of scopes.
// -------------------------------------------------------------------------------------
http.set_auth_token(&json_token.string_of("access_token").unwrap_or_default());

let sb_response_body = chilkat::StringBuilder::new();
if http.quick_get_sb("https://www.googleapis.com/oauth2/v3/userinfo", &sb_response_body).is_err() {
    println!("{}", http.last_error_text());
    println!("{}", sb_response_body.get_as_string().unwrap_or_default());
    return;

// Sample JSON Response

let json = chilkat::JsonObject::new();
json.set_emit_compact(false);
let _ = json.load(&sb_response_body.get_as_string().unwrap_or_default());
println!("{}", json.emit().unwrap_or_default());

// Sample response:

// {
//   "sub": "119999690625687999964",
//   "name": "Matt",
//   "given_name": "Matt",
