“我要创建一个项目，但是我的代码中出现httpresponse错误，我该怎么办？”

canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
    const config: AllowedActionsGuardConfig = route.data['AllowedActionsGuardConfig'];

    if (this.authService.currentUser.hasAllowedUserRoleAction(config.AllowedActions)) {
        this.router.navigate([
            `${!config.AbsolutePath ? state.url : ''}${config.NavigateToOnAuthorized}`,
        ]);

        return true;
    } else {
        this.router.navigate([
            `${!config.AbsolutePath ? state.url : ''}${config.FallbackOnUnauthorized}`,
        ]);
        return false;
    }
}
