Dans MSAL pour iOS et macOS

Objective-C :

MSALAccount *account = [application accountForIdentifier:accountIdentifier error:nil];

MSALSilentTokenParameters *silentParams = [[MSALSilentTokenParameters alloc] initWithScopes:scopes account:account];
[application acquireTokenSilentWithParameters:silentParams completionBlock:^(MSALResult *result, NSError *error) {

    // Check the error
    if (error && [error.domain isEqual:MSALErrorDomain] && error.code == MSALErrorInteractionRequired)
    {
        // Interactive auth will be required, call acquireTokenWithParameters:error:
    }
}];

Swift :

guard let account = try? application.account(forIdentifier: accountIdentifier) else { return }
let silentParameters = MSALSilentTokenParameters(scopes: scopes, account: account)
application.acquireTokenSilent(with: silentParameters) { (result, error) in

    guard let authResult = result, error == nil else {

    let nsError = error! as NSError

        if (nsError.domain == MSALErrorDomain &&
            nsError.code == MSALError.interactionRequired.rawValue) {

            // Interactive auth will be required, call acquireToken()
            return
        }
        return
    }
}

Dans MSAL Node, vous acquérez des jetons par le biais d’un flux de code d’autorisation avec une clé de preuve pour la norme PKCE (Proof Key for Code Exchange). MSAL Node utilise un cache de jeton en mémoire pour déterminer s’il existe des comptes d’utilisateur dans le cache. Si c’est le cas, l’objet de compte peut être transmis à la méthode acquireTokenSilent() pour récupérer un jeton d’accès mis en cache.

const msal = require("@azure/msal-node");

const msalConfig = {
    auth: {
        clientId: "your_client_id_here",
        authority: "your_authority_here",
    }
};

const pca = new msal.PublicClientApplication(msalConfig);
const msalTokenCache = pca.getTokenCache();

let accounts = await msalTokenCache.getAllAccounts();

    if (accounts.length > 0) {

        const silentRequest = {
            account: accounts[0], // Index must match the account that is trying to acquire token silently
            scopes: ["user.read"],
        };

        pca.acquireTokenSilent(silentRequest).then((response) => {
            console.log("\nSuccessful silent token acquisition");
            console.log("\nResponse: \n:", response);
            res.sendStatus(200);
        }).catch((error) => console.log(error));
    } else {
