Redux从我的数据库获取数据到存储中

Question

我在Redux中有一些问题，我想创建一个GET_TODO动作，以在每次调用时将数据从数据库中移入我的存储中。每次调用该函数时，都会清除基本状态，并且将我数据库中的所有数据都放入其中。

import { combineReducers } from "redux";
import { todolistFilters } from "./actions";
import axios from "axios";

const todos = (state = [], action) => {

  switch (action.type) {
    case "GET_TODO":
      axios
        .get("http://localhost:5000/urls/todos")
        .then((res) => {
          if (res.data) {
            console.log(res.data);
          }
        })
        .catch((err) => console.log(err));
      return [];
    case "ADD_TODO":
      return [
        ...state,
        {
          id: action.id,
          text: action.text,
          completed: false,
        },
      ];
    case "TOGGLE_TODO":
      return state.map((todo) =>
        todo.id === action.id ? { ...todo, completed: !todo.completed } : todo
      );
    case "DELETE_TODO":
      return state.filter((todo) => todo.id !== action.id);
    default:
      return state;
  }
};

const todolistFilter = (state = todolistFilters.SHOW_ALL, action) => {
  switch (action.type) {
    case "SET_TODOLIST_FILTER":
      return action.filter;
    default:
      return state;
  }
};

export default combineReducers({
  todos,
  todolistFilter,
});

来自JSON中我的Db的数据

[
  {
    "todo_id": "5f44b1fc00d1180f9c5bb18e",
    "content": "first sending to with sasasddaame id",
    "enable": false
  },
  {
    "todo_id": "5f44b4e0cd556e1e7465431e",
    "content": "first sending to with sasasddaame id",
    "enable": false
  },
  {
    "todo_id": "5f46513ad91b1b16a009016d",
    "content": "first sending to with sasasddaame id",
    "enable": false
  }
]

因此，在执行“ GET_TODO”之后，我应该会看到它，并且可以通过“ ADD_TODO”操作在其上添加更多内容
