javascript - 有没有一种方法可以从 React Redux 中的一个操作调用另一个操作

Question

我的 redux 操作中有两个操作...现在我有一个发出发布请求的登录表单..现在我想从登录操作中调用另一个操作。现在我连接了登录功能，但没有连接setLoading功能

例如

export const loginUser = ()=>dispatch=>{
 setLoading();
}

export const setLoading = ()=>({
type: SET_LOADING
})

您可以使用此答案的逻辑来帮助您。这个答案中给出了一个例子(这是获取产品的例子)。

React Redux fetching data from backend approach

For your problem, it's best to pay attention to this part of the link I gave you above, since you can use that logic for your program.

请注意上面的链接

// redux/product/product.actions.js
import { ShopActionTypes } from "./product.types";
import axios from "axios";

export const fetchProductsStart = () => ({
  type: ShopActionTypes.FETCH_PRODUCTS_START
});

export const fetchProductsSuccess = products => ({
  type: ShopActionTypes.FETCH_PRODUCTS_SUCCESS,
  payload: products
});

export const fetchProductsFailure = error => ({
  type: ShopActionTypes.FETCH_PRODUCTS_FAILURE,
  payload: error
});

export const fetchProductsStartAsync = () => {
  return dispatch => {
    dispatch(fetchProductsStart());
    axios
      .get(url)
      .then(response => dispatch(fetchProductsSuccess(response.data.data)))
      .catch(error => dispatch(fetchProductsFailure(error)));
  };
};
