javascript - 如何在 mobx 商店中引起 react

Question

我想自动获取如下所示的用户数据，但在观察行出现错误:

Uncaught Error: [mobx] Invariant failed: Cannot obtain atom from [object Object]

class AuthStore {

 @observable loggedIn = false;
 @observable userData;

  constructor() {
    observe(this, 'loggedIn', (change) => {
          if (change.loggedIn) {
            this.getUserData();
          }
    });
  }

  async getUserData() {
    const response = await ajax({
      url: '/users/me',
      method: 'GET'
    });
    const data = await response.json();
    //todo handle some errors here
    this.userData = data.user;
  }

}

你已经解决了吗？如果没有，请尝试使用 reaction 而不是 observe:

reaction(
  () => this.loggedIn,
  loggedIn => loggedIn && this.getUserData()
)
