¶ Standard agreement certification module

Update Time: 2025-05-14 08:32:28

This module contains authentication of OIDC, OAUTH 2.0, SAML, CAS standard protocol, obtains tokens, checking tokens, and logout. The method of initiating authentication needs to be used at the front end, get a token, check the token, and other methods need to be used in the backend.

Instructions:

import { AuthenticationClient } from "authing-js-sdk";
const authenticationClient = new AuthenticationClient({
  appId: "Application ID",
  secret: "Application key",
  appHost: "https://{YOUR_DOMAIN}.authing.cn",
  protocol: "oidc"
});
authenticationClient.buildAuthorizeUrl; // Texture front end login link
authenticationClient.getAccessTokenByCode; // Code change Token
authenticationClient.getAccessTokenByClientCredentials; // Machine license Access Token
authenticationClient.getUserInfoByAccessToken; // Token change user information
authenticationClient.getNewAccessTokenByRefreshToken; // Refresh Token
authenticationClient.introspectToken; // Test Token legality
authenticationClient.revokeToken; // Withdraw Token
authenticationClient.validateTicketV1; // Test CAS 1.0 ticket
authenticationClient.buildLogoutUrl; // Texture front end logout link

¶ OIDC

OpenID Connect is abbreviated as OIDC, an extension of OAuth 2.0, which mainly adds a semantic user information field.

  appId: "Application ID",
  secret: "Application key",
  appHost: "https://{YOUR_DOMAIN}.authing.cn",
