Question

所以我使用的是带有ApiClient助手的react-redux样板。它看起来像这样：

export default class ApiClient {
  constructor(req) {
    /* eslint-disable no-return-assign */
    methods.forEach((method) =>
      this[method] = (path, withCredentials, { params, data } = {}) => new Promise((resolve, reject) => {

        const request = superagent[method](formatUrl(path))

        if (withCredentials) {
          console.log('first of all, its true')
          console.log(this)
        }

        if (params) {
          request.query(params)
        }

        if (__SERVER__ && req.get('cookie')) {
          request.set('cookie', req.get('cookie'))
        }

        if (data) {
          request.send(data)
        }

        request.end((err, { body } = {}) => {

          return err ? reject(body || err) : resolve(body)

        })
      }))
    /* eslint-enable no-return-assign */
  }
  /*

   * constructors sometimes fails. Until it's patched, this is a solution to
   * "ApiClient is not defined" from issue #14.

   */
  empty() {}
}

我想将此连接到我的身份验证，以便我可以将标头添加到受保护的端点，如下所示：

@connect(state => ({ jwt: state.auth.jwt }))
export default class ApiClient {
  ...

但是，当我这样做时，我收到错误：Cannot read property 'store' of undefined。这里发生了什么？为什么我不能将常规类连接到redux商店？

更新：这是我的登录功能，它使用ApiClient助手：

export function loginAndGetFullInto(email, password) {
  return dispatch => {
    return dispatch(login(email, password))
    .then(() => {
      return dispatch(loadUserWithAuth())
    })
  }
}

我需要一些方法将商店或jwt传递到loadUserWithAuth函数......

connect函数不能用于React组件以外的任何其他功能。您可以做的是将商店实例传递到您的班级，然后直接致电store.dispatch，store.getState和store.subscribe。

请记住，如果您订阅，您还应具有取消订阅的功能，否则您的商店将永远保留对您的类实例的引用，从而造成内存泄漏。

是否可以将非组件类连接到redux存储？
