In today’s digital landscape, secure identity management is critical for businesses of all sizes. PingOne Advanced Identity Cloud offers a robust solution for managing user identities and securing access to applications and APIs. This guide will walk you through the process of integrating PingOne with a Single Page Application (SPA) and an API, ensuring seamless authentication and authorization.

Overview of PingOne Advanced Identity Cloud

PingOne is a leading identity-as-a-service (IDaaS) platform designed to simplify user access management. It supports modern authentication protocols like OAuth 2.0 and OpenID Connect, making it ideal for integrating with SPAs and APIs. By leveraging PingOne, developers can:

  1. Implement secure user authentication and authorization.
  2. Enable single sign-on (SSO) across multiple applications.
  3. Manage user identities and permissions centrally.

This tutorial assumes you have basic knowledge of OAuth 2.0, JavaScript, and REST APIs.

Setting Up Your PingOne Environment

Before diving into integration, you need to configure your PingOne environment. Follow these steps to get started:

  1. Create a PingOne Application:

    • Log in to your PingOne admin console.
    • Navigate to the “Applications” section and create a new application.
    • Configure the application type as “SPA” and specify the redirect URI for your frontend application.

  2. Generate Client Credentials:

    • After creating the application, PingOne will provide you with a Client ID and Client Secret. These credentials are essential for authenticating your application with PingOne.

  3. Enable OAuth 2.0 and OpenID Connect:

    • Ensure that OAuth 2.0 and OpenID Connect are enabled for your application.

Integrating PingOne with a Single Page Application (SPA)

SPAs are popular for their smooth user experience, but they require careful handling of authentication tokens. Here’s how to integrate PingOne with your SPA:

1. Implementing OAuth 2.0 Authorization Code Flow

The Authorization Code Flow is the recommended method for SPAs due to its enhanced security. Here’s how it works:

  • Step 1: Redirect to PingOne for Authentication
    When a user clicks the “Sign In” button, your SPA redirects them to PingOne’s login page.

    const signInWithPingOne = () => {
  const redirectUri = encodeURIComponent('https://your-frontend-app.com/callback');
  const authUrl = `https://your-pingone-domain.pingone.com/as/authorization.oauth2?` +
                  `response_type=code&` +
                  `client_id=YOUR_CLIENT_ID&` +
                  `redirect_uri=${redirectUri}&` +
                  `scope=openid email profile`;
  window.location.href = authUrl;
};

  • Step 2: Handling the Authentication Response
    After the user authenticates, PingOne redirects them back to your SPA with an authorization code.

    const handleCallback = async () => {
  const code = new URLSearchParams(window.location.search).get('code');
  if (!code) {
    throw new Error('Authorization code not found');
  }
  // Exchange the code for tokens
  const tokenResponse = await exchangeCodeForTokens(code);
  // Store tokens securely
  localStorage.setItem('access_token', tokenResponse.access_token);
  localStorage.setItem('id_token', tokenResponse.id_token);
};

  • Step 3: Exchanging the Authorization Code for Tokens
    Use the authorization code to obtain access and ID tokens from PingOne.

    const exchangeCodeForTokens = async (code) => {
  const redirectUri = encodeURIComponent('https://your-frontend-app.com/callback');
  const tokenEndpoint = 'https://your-pingone-domain.pingone.com/as/token.oauth2';
  const requestBody = new URLSearchParams({
    grant_type: 'authorization_code',
    client_id: 'YOUR_CLIENT_ID',
    client_secret: 'YOUR_CLIENT_SECRET',
    code: code,
    redirect_uri: redirectUri,
  });

  const response = await fetch(tokenEndpoint, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
    },
    body: requestBody,
  });

  return await response.json();
};

2. Securing API Requests

Once you have the access token, you can use it to make authenticated requests to your backend API.

const makeApiRequest = async () => {
  const accessToken = localStorage.getItem('access_token');
  if (!accessToken) {
    throw new Error('Access token not found');
  }

  const response = await fetch('https://your-backend-api.com/protected-resource', {
    headers: {
      'Authorization': `Bearer ${accessToken}`,
    },
  });

  return await response.json();
};

Integrating PingOne with an API

To secure your backend API, you need to validate incoming access tokens issued by PingOne. Here’s how to implement this:

1. Validating Access Tokens

Use the JWK Set Endpoint provided by PingOne to validate access tokens.

const validateAccessToken = async (accessToken) => {
  const jwksUri = 'https://your-pingone-domain.pingone.com/op/jwks';
  const response = await fetch(jwksUri);
  const jwks = await response.json();

  const decodedToken = decodeToken(accessToken);
  const kid = decodedToken.header.kid;

  const publicKey = jwks.keys.find(key => key.kid === kid);
  if (!publicKey) {
    throw new Error('Public key not found');
  }

  const验签结果 = jwt.verify(accessToken, publicKey);
  return 验签结果;
};

2. Protecting API Endpoints

Modify your API routes to check for a valid access token before processing requests.

const express = require('express');
const router = express.Router();

router.get('/protected-resource', async (req, res) => {
  const accessToken = req.headers.authorization?.split('Bearer ')[1];
  if (!accessToken) {
    return res.status(401).json({ message: 'Unauthorized' });
  }

  try {
    const validatedToken = await validateAccessToken(accessToken);
    res.json({ message: 'Access granted', user: validatedToken });
  } catch (error) {
    res.status(401).json({ message: error.message });
  }
});

module.exports = router;
