Is it possible to connect non component Class to redux store?

问题

So I am using a react-redux boilerplate that has an ApiClient helper. It looks like this:

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 */
  }
  /*
   * There's a V8 bug where, when using Babel, exporting classes with only
   * constructors sometimes fails. Until it's patched, this is a solution to
   * "ApiClient is not defined" from issue #14.

   */
  empty() {}
}

I want to connect this to my auth so that I can prepend headers to protected endpoints, like so:

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

However, when I do this, I get the error: Cannot read property 'store' of undefined. What's going on here? Why can't I connect a regular Class to the redux store?

Update: here's my login function, which uses the ApiClient helper:

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

I need some way to either pass the store, or the jwt, into the loadUserWithAuth function...

回答1:

The connect function is not going to work with anything other than React components. What you can do is pass your store instance to your class and call store.dispatch, store.getState, and store.subscribe directly.

Keep in mind that if you subscribe, you should also have functionality to unsubscribe, otherwise your store will be holding a reference to your class instance forever, creating a memory leak.
