我正在学习 Redux，我有两个 reducer，一个用来在页面上显示联系人的 contactReducer 和一个用来乱搞的 testReducer。在我的一个组件文件中，我有这个功能：
const mapDispatchToProps = (dispatch) => ({
getContacts: () => dispatch({ type: "TEST_ACTION" }),
});
这是我的两个减速器文件：contactReducer：
import { GET_CONTACTS } from "../actions/types";
const initialState = {
contacts: [
{
id: 1,
name: "John Doe",
email: "john@gmail.com",
phone: "555-555-5555",
},
{
id: 2,
name: "Karen Williams",
email: "karen@gmail.com",
phone: "444-444-4444",
},
{
id: 3,
name: "Henry Johnson",
email: "henry@gmail.com",
phone: "333-333-333",
},
],
};
export default function (state = initialState, action) {
switch (action.type) {
case GET_CONTACTS:
return {
...state,
};
default:
console.log("testing action in contactReducer");
return state;
}
}
和 testReducer：
import { GET_CONTACTS } from "../actions/types";
const initialState = {
contactsTest: [
{
id: 1,
name: "ffffffffffff",
email: "john@gmail.com",
phone: "555-555-5555",
},
{
id: 2,
name: "ggggggggggggg",
email: "karen@gmail.com",
phone: "444-444-4444",
},
{
id: 3,
name: "aaaaaaaaaaaaaa",
email: "henry@gmail.com",
phone: "333-333-333",
},
],
};
export default function (state = initialState, action) {
switch (action.type) {
case "TEST_ACTION":
return {
...state,
};
default:
console.log("testing action");
return state;
}
}
因此，我从 reducer 文件中的 console.log 语句中注意到，对于每个联系人，contactReducer 和 testReducer 的函数都使用以下行调用：
getContacts: () => dispatch({ type: "TEST_ACTION" }),
});
如果我有多个 reducer，但我只想调用它们的一个函数进行调度，我会怎么做？
