Reactjs 在减速器中设置redux的初始状态

嘿，伙计们，我陷入了这样一种情况，我必须将reducer的初始状态设置为某个值，让我向你们展示代码

首先，我有一个这样的动作创作者

export const fetchuser = () => {
  return async dispatch => {
    const res = await axios.get("/api/currentuser");
    dispatch({
      type: "fetchuser",
      payload: res.data
    });
  };
};

1.export default function(state = {}, action) {
   switch (action.type) {
      case "fetchuser":
        let data = action.payload||false;
        return {
          ...state,
          fetchuser: data       //any where you can access fetchuser data as well as previous state will not change.
        }
      default:
        return state;
   }
 }

它只是从api中获取数据并向reducer发送一个操作

export default function(state = {}, action) {
  switch (action.type) {
    case "fetchuser":
      return action.payload||false;
    default:
      return state;
  }
}

现在在第二个action creater中，我必须发出一个post请求并增加用户数据库中的“credits”值

export const handletoken = token => {
  return async dispatch => {
    const res = await axios.post("/api/stripe", token);
    dispatch({ type: "credits", payload: res.data });
  };
};

所以我在这里得到更新后的值，然后我把它传递给减速机

export default function(state = {}, action) {
  switch (action.type) {
    case "credits":
      return action.payload
    default:
      return state;
  }
}

然后将它们合并到reducer/index.js中

export default combineReducers({
auth: authreducer,
credits:creditsreducer
});

mapstatetoprops函数中app.js中auth reducer的控制台日志

 auth:
credits: 40
googleid: "109463598810933991924"
__v: 0
_id: "5d7fff2c4cb0604139055ce4"

在credits reducer中，正如你所见，我已经将状态的初始值定义为空对象，但我想将其设置为auth reducer的credits键的值，我可以很容易地将其设置为数组或硬编码的对象，但这里我需要将其值设置为已在另一个减速机中的值，那么如何实现这一点呢？

假设您需要等待

“fetchuser”

成功地在

credits减速机中设置积分，您可以处理
“fetchuser”
在您的
信用还原程序中执行操作
以及：

export default function(state = {}, action) {
  switch (action.type) {
    case "fetchuser":
      return action.payload ? action.payload.credits : state;
    case "credits":
      return action.payload
    default:
      return state;
  }
}

假设您需要等待
“fetchuser”
在
creditsreducer
中成功设置积分，那么您也可以在
creditsreducer
中处理
“fetchuser”
操作：

export default function(state = {}, action) {
  switch (action.type) {
    case "fetchuser":
      return action.payload ? action.payload.credits : state;
    case "credits":
      return action.payload
    default:
      return state;
  }
}

始终保持以前的减速器状态值。否则不使用redux状态值。像这样

export const fetchuser = () => {
  return async dispatch => {
    const res = await axios.get("/api/currentuser");
    dispatch({
      type: "fetchuser",
      payload: res.data
    });
  };
};

1.export default function(state = {}, action) {
   switch (action.type) {
      case "fetchuser":
        let data = action.payload||false;
        return {
          ...state,
          fetchuser: data       //any where you can access fetchuser data as well as previous state will not change.
        }
      default:
        return state;
   }
 }

按上述方式更改所有减速器。

了解，但现在如何在另一个减速器中将初始状态设置为该状态？就像这里我如何访问fetchuser属性？好的，我明白了，但是现在在另一个reducer中我如何将初始状态设置为这个状态？像这里一样，我如何访问fetchuser属性？
