angular - 使用 MSAL 库 v2 的 Angular 应用程序在重新加载页面后显示登录页面

Question

MSAL 配置符合以下代码片段：

export const msalConfig: Configuration = {
    auth: {
        clientId: 'TheMaskedClientId', // This is the ONLY mandatory field that you need to supply.
        authority: b2cPolicies.authorities.signUpSignIn.authority, // Defaults to "https://login.microsoftonline.com/common"
        knownAuthorities: [b2cPolicies.authorityDomain], // Mark your B2C tenant's domain as trusted.
        redirectUri: 'http://localhost:4200', // Points to window.location.origin. You must register this URI on Azure portal/App Registration.
        postLogoutRedirectUri: 'http://localhost:4200', // Indicates the page to navigate after logout.
        navigateToLoginRequestUrl: true, // If "true", will navigate back to the original request location before processing the auth code response.
    },
    cache: {
        cacheLocation: BrowserCacheLocation.LocalStorage, // Configures cache location. "sessionStorage" is more secure, but "localStorage" gives you SSO between tabs.
        storeAuthStateInCookie: isIE, // Set this to "true" if you are having issues on IE11 or Edge
    },
    system: {
        loggerOptions: {
            loggerCallback(logLevel: LogLevel, message: string) {
                console.log(message);
            },
            logLevel: LogLevel.Verbose,
            piiLoggingEnabled: false
        }
    }
}

我能够成功登录并使用该应用程序，但是当我刷新页面时，会出现登录提示以进行登录。此配置中缺少什么？
