Reactjs axios返回多个值的Redux Thunk操作

我有一个React应用程序，它使用

redux thunk

和

axios

获取API。该操作成功发射，但返回多个有效载荷，这意味着它发射了多次

我怎样才能让它只燃烧一次

下面是它返回的内容

只需从

useffect

的依赖项数组中删除

leagueTable

，这样它只会在安装组件后获取它们。因为现在有了一个循环：

Get leagues->leagueTable Update->Useffect看到依赖项数组中的

leagueTable

发生了更改，并再次调用Get leagues，我们得到了一个循环

const-League=props=>{
useffect（（）=>{
props.getLeagueTable（）；
}, []); //
import Axios from "axios";
import { fetchEnglishLeagueTable } from "./ActionTypes";

export function fetchEnglishTable() {
  var url = "https://api.football-data.org/v2/competitions/PL/matches";
  var token = "52c8d88969d84ac9b17edb956eea33af";
  var obj = {
    headers: { "X-Auth-Token": token }
  };
  return dispatch => {
    return Axios.get(url, obj)
      .then(res => {
        dispatch({
          type: fetchEnglishLeagueTable,
          payload: res.data
        });
      })
      .catch(e => {
        console.log("Cant fetch ", e);
      });
  };
}


import { fetchEnglishLeagueTable } from "../actions/ActionTypes";
const initialState = {
  EnglishTable: {}
};

const rootReducer = (state = initialState, action) => {
  switch (action.type) {
    case fetchEnglishLeagueTable:
      return {
        ...state,
        EnglishTable: action.payload
      };
    default:
      return state;
  }
};

export default rootReducer;

const League = props => {
  useEffect(() => {
    props.getLeagueTable();
  }, [props.leagueTable]);
  console.log(props.leagueTable);
  return <p>ihi</p>;
};
const mapStateToProps = state => ({
  leagueTable: state.EnglishTable
});
const mapDispatchToProps = dispatch => {
  return { getLeagueTable: () => dispatch(fetchEnglishTable()) };
};

export default connect(mapStateToProps, mapDispatchToProps)(League);

import rootReducer from "./Reducer";
import thunk from "redux-thunk";

const store = createStore(rootReducer, applyMiddleware(thunk));

export default store;
