Question

这是我的商店，已实施thunk：

store/index.js

import { createStore, applyMiddleware } from "redux";
import reducer from "../reducers/";
import thunk from "redux-thunk";

const store = createStore(reducer, applyMiddleware(thunk));
export default store;

这是我的动作：

actions/index：

export const remove = function(id) {
  return {
    type: "remove",
    payload: setTimeout(function() {
      return id;
    }, 2000)
  };
};

export const add = function() {};

export default { remove, add };

这是我的调度功能：

component/Item.js

import React from "react";
import { connect } from "react-redux";
import { bindActionCreators } from "redux";
import { remove } from "../actions/";

const Item = props => {
  function removeTrigger() {
    props.remove(props.item.id);
  }
  return (
    <li>
      {props.item.name} <button onClick={removeTrigger}>Delete</button>
    </li>
  );
};

function mapAction(dispatch) {
  return bindActionCreators({ remove }, dispatch);
}

export default connect(
  null,
  mapAction
)(Item);

单击delete按钮时，我收到控制台消息。但是ID不会被删除。有人可以帮助我在这里正确实现thunk优势吗？

如何用正确的方式在`redux`中实现`thunk`处理异步功能？
