Redux Reselect未从api获取数据

问题描述

我使用Redux并重新选择，但是我无法通过connect函数从服务器获取数据。但是如果我使用useSelector和useEffect钩子。它将正常工作并成功获取数据。 但是我需要使用connect函数而不是useSelector。 我在https://codesandbox.io工作过，源代码在下面的链接中。

示例代码在这里。 非常感谢?

import { createSlice } from "@reduxjs/toolkit";

import api from "./api";
const initialUser = localStorage.getItem("user")
  ? JSON.parse(localStorage.getItem("user"))
  : null;

// Slice
const slice = createSlice({
  name: "user",initialState: {
    user: initialUser,users: [],isLoading: false,error: false
  },reducers: {
    startLoading: (state) => {
      state.isLoading = false;
    },hasError: (state,action) => {
      state.error = action.payload;
      state.isLoading = false;
    },loginSuccess: (state,action) => {
      state.user = action.payload;
      localStorage.setItem("user",JSON.stringify(action.payload));
    },logoutSuccess: (state,action) => {
      state.user = null;
      localStorage.removeItem("user");
    },useRSSuccess: (state,action) => {
      state.users = action.payload;
      state.isLoading = true;
    },getUsers: (state,action) => {
      state.users = action.payload;
    }
  }
});
export default slice.reducer;
// Actions
const {
  loginSuccess,logoutSuccess,useRSSuccess,startLoading,hasError
} = slice.actions;

export const fetchUsers = () => async (dispatch) => {
  dispatch(startLoading());
  try {
    await api
      .get("/users")
      .then((response) => dispatch(useRSSuccess(response.data)));
  } catch (e) {
    dispatch(hasError(e.message));
  }
};
export const login = ({ username,password }) => async (dispatch) => {
  try {
    // const res = await api.post('/api/auth/login/',{ username,password })
    dispatch(loginSuccess({ username }));
  } catch (e) {
    return console.error(e.message);
  }
};
export const logout = () => async (dispatch) => {
  try {
    // const res = await api.post('/api/auth/logout/')
    return dispatch(logoutSuccess());
  } catch (e) {
    return console.error(e.message);
  }
};

export const selectUsers = (state) => state.user.users;
// App.js
const App = (props) => {
  console.log("users",props.users)
  return <div>sample</div>
}
const mapStatetoProps = (state) => {
  return { users: selectUsers(state) };
};
export default connect(mapStatetoProps)(App);

解决方法

看看redux-api-middleware，它提供了一种更好的方法来将数据获取集成到redux工作流中
