private static getContext(): Msal.UserAgentApplication {
    if (AuthenticationService.Context) return AuthenticationService.Context;
    const logger = new Msal.Logger((_logLevel,message,_piiEnabled) => {
        console.log(message);
    },{ level: Msal.LogLevel.Verbose,correlationId: "12345" });

    AuthenticationService.Context = new Msal.UserAgentApplication(
        Environment().authentication.clientId,AuthenticationService.getAuthority(),(errorDesc,token,error,_tokenType) => {
            if (token) {
                AuthenticationService.isAuthenticated = true;
                AuthenticationService.accessToken = token;
            } else {
                const localizedError: string = LocalizationService.localize(error);
                alert(localizedError !== error ? localizedError : errorDesc);
            }
        },{
            logger: logger,storeAuthStateInCookie: true,state: "12345",cacheLocation: "localStorage" // enable this for IE,as sessionStorage does not work for localhost.
        });
    if (AuthenticationService.Context.getUser()) {
        AuthenticationService.isAuthenticated = true;
    }

    return AuthenticationService.Context;
}

我们有登录方法：

public static login(): void {
    const context: Msal.UserAgentApplication = AuthenticationService.getContext();
    if (context.loginInProgress()) return;
    AuthenticationService.CurrentUser = null;
    context.loginRedirect(AuthenticationService.SCOPES);
}

我们有获取图表令牌的方法：

public static async getGraphToken(): Promise<string | null> {
    const authContext: Msal.UserAgentApplication = AuthenticationService.getContext();
    const cachedUser: Msal.User = authContext.getUser();
    if (!cachedUser) {
        return null;
    }
    return authContext.acquireTokenSilent(AuthenticationService.SCOPES);
}

当我使用图形令牌获取用户照片时,我有：

{
    "error": {
        "code": "OrganizationFromTenantGuidNotFound","message": "The tenant for tenant guid '68cc0dcb-5873-4ea0-a498-fe57e9b51827' does not exist.","innerError": {
            "request-id": "b402e405-342a-4002-a880-84f30413cbf7","date": "2018-11-30T23:39:23"
         }
     }
}
