当我运行以下代码时会发生这种情况：

isAuthenticated(): Observable<boolean> {
        return this.http.post('/isAuthenticated').pipe(
            map(() => {
                return true;
            }),
            catchError((err) => {
                console.log('In catchError');
                this.router.navigate(['/login']);
                return  Observable.of(false);
            }));
    }

在服务器端，/ isAuthenticated重定向到/ login / authAjax，返回401.我想捕获此错误并导航到/ login。

但是我不明白如何防止写入日志，因为它似乎是在我自己编写的'In catchError'之前编写的。

如果我忘记添加相关信息，请向我提出进一步的详细信息。
