我已经成功创建了一个对以下端点执行呼叫请求的操作

https://api-football-v1.p.rapidapi.com/v2/statistics/{league_id}/{team_id}

API 文档在这里

我在代码沙箱中创建了一个小演示，您可以在其中看到我可以显示匹配项wins，draws并loses在我Stats.js的圣保罗团队组件中正确显示（这是一个示例）

这里我已经完成了所有步骤，我只向您展示实现它的相关代码

在我的减速器中，我创建了以下案例

  RECEIVE_TEAMS_STATS_WIN_HOME,
  RECEIVE_TEAMS_STATS_WIN_AWAY,
  RECEIVE_TEAMS_STATS_DRAW_HOME,
  RECEIVE_TEAMS_STATS_DRAW_AWAY,
  RECEIVE_TEAMS_STATS_LOSE_HOME,
  RECEIVE_TEAMS_STATS_LOSE_AWAY

在我最初的状态下，我有

  teamsStatsWinHome: [],
  teamsStatsWinAway: [],
  teamsStatsDrawHome: [],
  teamsStatsDrawAway: [],
  teamsStatsLoseHome: [],
  teamsStatsLoseAway: [],

这些是我的案例 

 case RECEIVE_TEAMS_STATS_WIN_HOME:
      return {
        ...state,
        teamsStatsWinHome: action.json,
        isTeamsStatsLoading: false
      };
    case RECEIVE_TEAMS_STATS_WIN_AWAY:
      return {
        ...state,
        teamsStatsWinAway: action.json,
        isTeamsStatsLoading: false
      };
    case RECEIVE_TEAMS_STATS_DRAW_HOME:
      return {
        ...state,
        teamsStatsDrawHome: action.json,
        isTeamsStatsLoading: false
      };
    case RECEIVE_TEAMS_STATS_DRAW_AWAY:
      return {
        ...state,
        teamsStatsDrawAway: action.json,
        isTeamsStatsLoading: false
      };
    case RECEIVE_TEAMS_STATS_LOSE_HOME:
      return {
        ...state,
        teamsStatsLoseHome: action.json,
        isTeamsStatsLoading: false
      };
    case RECEIVE_TEAMS_STATS_LOSE_AWAY:
      return {
        ...state,
        teamsStatsLoseAway: action.json,
        isTeamsStatsLoading: false
      };

这里是我对 API 端点的调用请求的操作

export function getTeamsStats(league, team) {
  return function(dispatch) {
    return axios
      .get(
        `https://www.api-football.com/demo/api/v2/statistics/${league}/${team}`
      )
      .then(res => {
        let homewins = res.data.api.statistics.matchs.wins.home;
        dispatch(receivedTeamsStatWinHome(homewins));
        let awaywins = res.data.api.statistics.matchs.wins.away;
        dispatch(receivedTeamsStatWinAway(awaywins));
        let drawhome = res.data.api.statistics.matchs.draws.home;
        dispatch(receivedTeamsStatDrawHome(drawhome));
        let drawaway = res.data.api.statistics.matchs.draws.away;
        dispatch(receivedTeamsStatDrawAway(drawaway));
        let losehome = res.data.api.statistics.matchs.loses.home;
        dispatch(receivedTeamsStatLoseHome(losehome));
        let loseaway = res.data.api.statistics.matchs.loses.away;
        dispatch(receivedTeamsStatLoseAway(loseaway));
      })
      .catch(e => {
        console.log(e);
      });
  };

然后 getTeamsStats将函数放入fetchLeaguesList以获取圣保罗结果作为示例

这是我组件中的相关代码Stats.js

let Stats = ({
  teamsStatsWinHome,
  teamsStatsWinAway,
  teamsStatsDrawHome,
  teamsStatsDrawAway,
  teamsStatsLoseHome,
  teamsStatsLoseAway,
  loading
}) => {
  let stats = "";

  if (
    teamsStatsWinHome &&
    teamsStatsWinAway &&
    teamsStatsDrawHome &&
    teamsStatsDrawAway &&
    teamsStatsLoseHome &&
    teamsStatsLoseAway
  ) {
    stats = (
      <div className="col-sm-6">
        <div className="card detail-card border-0 rounded-0 bg-transparent">
          <div className="card-body text-decoration-none text-secondary">
            {JSON.stringify(teamsStatsWinHome)}
            {JSON.stringify(teamsStatsWinAway)}
            {JSON.stringify(teamsStatsDrawHome)}
            {JSON.stringify(teamsStatsDrawAway)}
            {JSON.stringify(teamsStatsLoseHome)}
            {JSON.stringify(teamsStatsLoseAway)}
          </div>
        </div>
      </div>
    );
  }

正如您在代码框演示中看到的那样，它按预期工作，但我不知道我是否以正确的方式处理 Redux 状态、调用操作和组件。

我的问题是，对吗？我可以做得更好吗？如果是，我应该如何重构？

代码沙盒演示中的任何重构和代码更改都可以接受答案

调度单个动作来更新结果的存储，而不是在结果中为每个字段调度多个动作。

src/actions/index.js


export const RECEIVE_TEAMS_STATS = "RECEIVE_TEAMS_STATS";


export const receivedTeamsStat = json => ({
  type: RECEIVE_TEAMS_STATS,
  json: json
});

export function getTeamsStats(league, team) {
  return function(dispatch) {
    return axios
      .get(
        `https://www.api-football.com/demo/api/v2/statistics/${league}/${team}`
      )
      .then(res => {
        const { 
          wins: { home: teamsStatsWinHome, away: teamsStatsWinAway }, 
          draws: { home: teamsStatsDrawHome, away: teamsStatsDrawAway }, 
          loses: { home: teamsStatsLoseHome, away: teamsStatsLoseAway }
        } = res.data.api.statistics.matchs;
        const teamStats = {
          teamsStatsWinHome,
          teamsStatsWinAway,
          teamsStatsDrawHome,
          teamsStatsDrawAway,
          teamsStatsLoseHome,
          teamsStatsLoseAway
         }
        dispatch(receivedTeamsStat(teamStats));
      })
      .catch(e => {
        console.log(e);
      });
  };

所有 6 个动作（RECEIVE_TEAMS_STATS_WIN_HOME, RECEIVE_TEAMS_STATS_WIN_AWAY, RECEIVE_TEAMS_STATS_DRAW_HOME, RECEIVE_TEAMS_STATS_DRAW_AWAY, RECEIVE_TEAMS_STATS_LOSE_HOME, RECEIVE_TEAMS_STATS_LOSE_AWAY）都可以滚动到一个RECEIVE_TEAMS_STATS动作中并按如下方式处理：

src/reducers/index.js

import {
  //..
  RECEIVE_TEAMS_STATS
} from "../actions";


const reducer = (state = initialState, action) => {
  switch (action.type) {
    //...
    case RECEIVE_TEAMS_STATS:
      return {
        ...state,
        ...action.json,
        isTeamsStatsLoading: false
      };
    //...
}

将单个更新分派到 store 的好处是Stats组件渲染一次，而不是从 API 返回结果时渲染 6 次。
