웹 API를 호출하는 데스크톱 앱: 토큰 획득

iOS 및 macOS용 MSAL에서

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
    }
}

MSAL Node에서 PKCE(Proof Key for Code Exchange)를 사용하여 인증 코드 흐름을 통해 토큰을 획득합니다. MSAL Node는 메모리 내 토큰 캐시를 사용하여 캐시에 사용자 계정이 있는지 확인합니다. 계정이 있는 경우에는 계정 개체를 acquireTokenSilent() 메서드에 전달하여 캐시된 액세스 토큰을 검색할 수 있습니다.

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 {
        const {verifier, challenge} = await msal.cryptoProvider.generatePkceCodes();
