无法静默获取令牌或使用 msal-browser 通过重定向获取令牌

问题描述 投票:0回答:2

我正在尝试开发一个 VueJS 单页应用程序,让您登录到 AAD,以便我可以获得访问令牌来调用各种 API(例如 Graph)。

用户登录后,您必须获取令牌,有两种方法可以执行此操作:静默(如果失败,则使用重定向体验)。

但是,我无法使用这两种方法获取令牌:

export default class AuthService {
  constructor() {
    console.log('[AuthService.constructor] started constructor');

    this.app = new Msal.PublicClientApplication(msalConfig);
    this.signInType = 'loginRedirect';
  }

  init = async () => {
    console.log('[AuthService.init] started init');

    await this.app.handleRedirectPromise().catch(error => {
      console.log(error);
    });


    try {

      let signedInUser = this.app.getAllAccounts()[0];

      //  if no accounts, perform signin
      if (signedInUser === undefined) {
        alert(this.app.getAllAccounts().length == 0)
        await this.signIn();
        signedInUser = this.app.getAllAccounts()[0];
        console.log("user has been forced to sign in")
      }

      console.log("Signed in user is: ", signedInUser);

      // Acquire Graph token
      try {
        var graphToken = await this.app.acquireTokenSilent(authScopes.graphApi);
        console.log("(Silent) Graph token is ", graphToken);
        alert(graphToken);
      } catch (error) {
        alert("Error when using silent: " + error)
        try {
          var graphToken = await this.app.acquireTokenRedirect(authScopes.graphApi);
        } catch (error) {
          alert ("Error when using redirect is: " +  error)
        }

        alert("(Redirect) Graph token is " + graphToken);
      }

    } catch (error) {
      console.log('[AuthService.init] handleRedirectPromise error', error);
    }
  }

  signIn = async () => {
    console.log('[AuthService.signIn] signInType:', this.signInType);
    this.app.loginRedirect("user.read", "https://xxx.azurewebsites.net/user_impersonation");
  }

  signOut = () => {
    this.app.logout();
  }
}

加载 SPA 后,我会被重定向到 AAD 登录页面。

然后我收到以下警报提示:

使用静默时出错:ClientAuthError: no_account_in_silent_request: Please pass an account object,没有账户信息不支持静默流程

使用重定向时的错误是:BrowserAuthError:interaction_in_progress:交互当前正在进行。调用交互API之前请确保本次交互已经完成。

(重定向)图标记未定义

即使我已登录,为什么

acquireTokenSilent
认为我未登录?

BrowserAuthError: interaction_in_progress
是什么意思?我在网上搜索了这个,我发现的唯一结果是因为有人使用了过时版本的 msal-browser。就我而言,我使用的是最新最好的(v2.0.1)。


更新1:

我使用以下代码摘录修复了静默令牌获取问题:

const silentRequest = {
  account: signedInUser,
  scopes: authScopes.graphApi.scopes1
}
var graphToken = await this.app.acquireTokenSilent(silentRequest);

看起来我以错误的格式传递了范围(即应该传递一个数组,但它实际上不是一个数组!)

但是 Microsoft 文档中关于如何使用的内容存在差异

acquireTokenSilent

here,我们被告知只需将一组范围传递给

acquireTokenSilent
方法。但是,在这里,我们被告知还要在范围旁边传递 accountInfo。

让我们看看我现在是否可以

acquireTokenRedirect
工作...


更新2: 经过多次尝试和错误,我终于成功了。

acquireTokenRedirect

import * as Msal from '@azure/msal-browser'; const msalConfig = { auth: { clientId: "XYZ", authority: "ABC", }, cache: { cacheLocation: 'localStorage', storeAuthStateInCookie: true } }; export default class AuthenticationService { constructor() { this.app = new Msal.PublicClientApplication(msalConfig) } init = async () => { try { let tokenResponse = await this.app.handleRedirectPromise(); let accountObj; if (tokenResponse) { accountObj = tokenResponse.account; } else { accountObj = this.app.getAllAccounts()[0]; } if (accountObj && tokenResponse) { console.log("[AuthService.init] Got valid accountObj and tokenResponse") } else if (accountObj) { console.log("[AuthService.init] User has logged in, but no tokens."); try { tokenResponse = await this.app.acquireTokenSilent({ account: this.app.getAllAccounts()[0], scopes: ["user.read"] }) } catch(err) { await this.app.acquireTokenRedirect({scopes: ["user.read"]}); } } else { console.log("[AuthService.init] No accountObject or tokenResponse present. User must now login."); await this.app.loginRedirect({scopes: ["user.read"]}) } } catch (error) { console.error("[AuthService.init] Failed to handleRedirectPromise()", error) } } }

成功工作,这是可能对其他人有帮助的摘录:

acquireTokenRedirect

MSAL v2 需要迁移 RedirectURI。

Azure AD warning: This app has implicit grant settings enabled. If you are using any of these URIs in a SPA with MSAL.js 2.0, you should migrate URIs.

Migrate URI Message: The latest version of MSAL.js uses the authorization code flow with PKCE and CORS.
