无法在移动设备上设置本地存储，做出反应

Question

I'm trying to save a JSON Web Token in local storage for authentication purposes. When a user logs in I call the following method.

  static authenticateUser(token) {
    try {
      window.localStorage.setItem('token', token);
    } catch (error) {
      alert(error);
    }
  }

This works well on desktop but doesn't work at all on mobile. Safari throws a QuotaExceededError and Chrome fails silently. Is localStorage not a viable solution for mobile? Should I use cookies instead?

Answer 1

Safari throws QuotaExceededError in Private Mode. Just check if you are using provide mode. Also, try to use sessionStorage instead of localStorage unless you need to store information independent of user' session.
