Quickstart: Sign in users and get an access token in a JavaScript SPA using the auth code flow with PKCE

  • Artikkel

Welcome! This probably isn't the page you were expecting. While we work on a fix, this link should take you to the right article:

Quickstart: Sign in users in single-page apps (SPA) via the authorization code flow with Proof Key for Code Exchange (PKCE) using JavaScript

We apologize for the inconvenience and appreciate your patience while we work to get this resolved.

In this quickstart, you download and run a code sample that demonstrates how a JavaScript single-page application (SPA) can sign in users and call Microsoft Graph using the authorization code flow with Proof Key for Code Exchange (PKCE). The code sample demonstrates how to get an access token to call the Microsoft Graph API or any web API.

See How the sample works for an illustration.

Prerequisites

Step 1: Configure your application in the Azure portal

For the code sample in this quickstart to work, add a Redirect URI of http://localhost:3000/.

Already configured Your application is configured with these attributes.

Step 2: Download the project

Run the project with a web server by using Node.js

Step 3: Your app is configured and ready to run

We have configured your project with values of your app's properties.

Run the project with a web server by using Node.js.

  1. To start the server, run the following commands from within the project directory:

    npm install
npm start

  2. Go to http://localhost:3000/.

  3. Select Sign In to start the sign-in process and then call the Microsoft Graph API.

    The first time you sign in, you're prompted to provide your consent to allow the application to access your profile and sign you in. After you're signed in successfully, your user profile information is displayed on the page.

MSAL.js

The MSAL.js library signs in users and requests the tokens that are used to access an API that's protected by Microsoft > identity platform. The sample's index.html file contains a reference to the library:

<script type="text/javascript" src="https://alcdn.msauth.net/browser/2.0.0-beta.0/js/msal-browser.js" integrity=
"sha384-r7Qxfs6PYHyfoBR6zG62DGzptfLBxnREThAlcJyEfzJ4dq5rqExc1Xj3TPFE/9TH" crossorigin="anonymous"></script>

If you have Node.js installed, you can download the latest version by using the Node.js Package Manager (npm):

npm install @azure/msal-browser
