我们正在使用MSAL.js来验证用户到Azure AD B2C实例的身份。用户可以使用本地帐户,也可以使用其凭据从另一个Azure Active Directory实例登录。
已登录,我们的SPA使用acquireTokenSilent获取访问令牌,并回退到AcquisitionTokenPopup。
我们注意到的是,当AcquisitionTokenSilent超时时,仍可以在后台检索令牌,并且使用令牌更新应用程序本地存储。但是,在应用程序中,我们继续调用了acquireTokenPopup。用户在acquireTokenPopup中输入其凭据后,弹出窗口将显示“错误请求”。用户可以关闭弹出窗口,如果刷新应用程序,则现在将登录。
对于我们的用户而言,这种体验不是很好的体验。
只是想知道这是一个已知问题还是预期的行为?
以下是我们代码中的相关摘录。我们将UserAgentApplication包装在MsalAuthenticationManager对象中。
function getMsalAuthenticationManager(authority: IMSALAuthorityConfig): IMsalAuthenticationManager {
return new MsalAuthenticationManager(
appConfig.msal.clientId,
authority.signUpOrSignInAuthority,
authority.passwordResetAuthority,
{
loadFrameTimeout: 15000,
endPoints: endPointsMap,
cacheLocation: appConfig.msal.cacheLocation // localStorage
}
);
}
// MsalAuthenticationManager constructor
constructor(
private applicationId: string,
authority?: string,
authorityForPasswordReset?: string,
msalOptions?: IMsalOptions
) {
var onTokenReceived = authorityForPasswordReset
? (errorDesc: string, token: string, error: string, tokenType: string) => {
// When the user clicks on the forgot password link, the following error is returned to this app.
// In this case we need to re-instantiate the UserAgentApplication object with the Password Reset policy.
if (errorDesc && errorDesc.indexOf("AADB2C90118") > -1) {
this._msal = new UserAgentApplication(
applicationId,
authorityForPasswordReset,
onTokenReceived,
msalOptions
);
this.signIn();
}
}
: (errorDesc: string, token: string, error: string, tokenType: string) => {};
this._msal = new UserAgentApplication(applicationId, authority, onTokenReceived, msalOptions);
this.acquireToken = this.acquireToken.bind(this);
this.signIn = this.signIn.bind(this);
this.signOut = this.signOut.bind(this);
this.getResourceForEndpoint = this.getResourceForEndpoint.bind(this); // Gets the scope for a particular endpoint
this.acquireToken = this.acquireToken.bind(this);
}
public acquireToken(scopes: string[]): Promise<string> {
return new Promise((resolve, reject) => {
this._msal
.acquireTokenSilent(scopes)
.then((accessToken: string) => resolve(accessToken))
.catch((acquireTokenSilentError: string) => {
this._msal
.acquireTokenPopup(scopes)
.then((accessToken: string) => resolve(accessToken))
.catch((acquireTokenPopupError: string) => reject(acquireTokenPopupError));
});
});
}

我有一个类似的问题,原因是令牌仍然存在但已过期,并且由于msal.js不检查令牌过期,因此您将被视为已登录,但是您的令牌实际上是无效的,并且带有承载的httpRequests将因未授权而失败。您应该记录acquiretokenSilent错误并查找“ AADB2C90077”错误,如果令牌已过期,请调用logout()。
