登录Auth0后找不到如何获取Access Token

Question

我正在使用 Auth0 登录用户。 用户第一次登录时，我收到 json 响应，其中包含 access_token 和 ID 令牌。

我想保存它，这样我就可以使用访问令牌来访问我的一个 API。

我找不到调用 xxxx.auth0.com/oauth 的方法。 如果我能找到该方法并将响应保存在我的 cookies 中，那就太好了。 （除非我不应该这样做）。

我也尝试过找到一种获取访问令牌的方法，但我不明白这是怎么可能的。 我很难处理文档。

我遇到的另一个问题是用户重新登录或刷新页面时。 没有给我访问令牌。 我什至没有看到 xxxx.auth0.com/oauth 的网络响应。 安全不是我的强项。 但我希望 Auth0 可以减轻一些负担。

export class AuthService {
  // Create an observable of Auth0 instance of client
  auth0Client$ = (from(
    createAuth0Client({
      domain: "XXXXX.auth0.com",
      client_id: "JXXXXXXXXXXXXXXXXXXXXG",
      redirect_uri: `${window.location.origin}` + `/home`
    })
  ) as Observable<Auth0Client>).pipe(
    shareReplay(1), // Every subscription receives the same shared value
    catchError(err => throwError(err))
  );
  // Define observables for SDK methods that return promises by default

  localAuthSetup() {

    // (e.g., from a route guard)
    // Ensure Auth0 client instance exists
    this.auth0Client$.subscribe((client: Auth0Client) => {
      // Call method to log in
      client.loginWithRedirect({
        redirect_uri: `${window.location.origin}` + `/home`,
        appState: { target: redirectPath }

  }

  handleAuthCallback() {
    // Call when app reloads after user logs in with Auth0
    const params = window.location.search;
    if (params.includes('code=') && params.includes('state=')) {
      let targetRoute: string; // Path to redirect to after login processsed
      const authComplete$ = this.handleRedirectCallback$.pipe(
        // Have client, now call method to handle auth callback redirect
        tap(cbRes => {
          // Get and set target redirect route from callback results
          targetRoute = '/home';
        }),
        concatMap(() => {
          // Redirect callback complete; get user and login status
          return combineLatest([
            this.getUser$(),
            this.isAuthenticated$
          ]);
        })
      );
      // Subscribe to authentication completion observable
      // Response will be an array of user and login status
      authComplete$.subscribe(([user, loggedIn]) => {
        // Redirect to target route after callback processing
        this.router.navigate([targetRoute]);
      });
    }
  }

  logout() {
    // Ensure Auth0 client instance exists
    this.auth0Client$.subscribe((client: Auth0Client) => {
      // Call method to log out
      client.logout({
        client_id: "JxxxxxxxxxxxxxxxxxxxxxxG",
        returnTo: `${window.location.origin}`
      });
    });
  }
}

如果我订阅 auth0client 我可以看到令牌。 但是我无法访问它来缓存私有。

  console.log(data.cache.cache["default::openid profile email"])

我有同样的问题。 而且我同意这个人在通过 Auth0 SPA sdk 时会感到迷茫，因为没有明确的属性或 function 来获取访问令牌。

您可以通过调用 Auth0Client 的 getTokenSilently() 方法获取访问令牌。

为了最简单的方法，可以在 Auth 服务中添加以下方法来设置访问令牌，并且可以在登录后立即调用此方法。 （这可能不是一个好主意，但会帮助您理解流程。）

setAccessToken() {
  this.auth0Client$.subscribe(async (client: Auth0Client) => {
    this.AccessToken = await client.getTokenSilently();});   
}

您还可以在 authService 中添加 observable 方法并从任何地方调用此 observable（例如 http 拦截器在调用 api 的 header 中添加访问令牌）

getTokenSilently$(options?): Observable<string> {
   return this.auth0Client$.pipe(
   concatMap((client: Auth0Client) => from(client.getTokenSilently(options))));
}

我发现获取访问令牌并将其与 http 拦截器一起使用以将其添加到 http 调用的 header 的最佳示例之一是在此处输入链接描述
