[英]Redux Toolkit: lifecycle action types doesn't sync up when dispatching multiple async thunk actions in one thunk
[英]React Redux Toolkit Doesn't Dispatch Async Thunk
我正在使用 Redux/Toolkit,我想使用 Async Thunk 进行身份验证过程。 但是当我尝试分派该函数时它会返回一个错误。
在这种情况下我该怎么办? 这是我第一次使用 Async Thunk,所以我不知道如何面对这个问题。
顺便说一下,我正在使用 Typescript。 所以,我认为这个问题主要是关于 Typescript 的。
userSlice.tsx 文件:
import {createSlice, createAsyncThunk} from "@reduxjs/toolkit"
import {InterfaceUserSlice} from "../typescript/interfaceUserSlice"
import axios from "../axios"
export const UserLogin = createAsyncThunk("/users/authentication", async (user:{email:string,password:string}) => {
try{
const res = await axios.post("/users/authentication", user)
...
} catch(err){
...
}
})
const initialState:InterfaceUserSlice = {
...
}
const userSlice = createSlice({
name: "user",
initialState,
reducers: {},
extraReducers: (builder) => {}
})
export default userSlice.reducer
Login.tsx 页面文件:
import React, {useState} from "react"
import { useDispatch } from "react-redux"
import { UserLogin } from "../redux/userSlice"
const Login = () => {
const dispatch = useDispatch()
const [email, setEmail] = useState<string>("")
const [password, setPassword] = useState<string>("")
function LoginRequest(){
dispatch(UserLogin({email,password})) //This is the point that I have the error which says: "Argument of type 'AsyncThunkAction<void, { email: string; password: string; }, AsyncThunkConfig>' is not assignable to parameter of type 'AnyAction'."
}
return (
...
)
}
export default Login
尝试将 args 的类型传递给createAsyncThunk
:
type ReturnedType = any // The type of the return of the thunk
type ThunkArg = { email:string, password:string }
export const UserLogin = createAsyncThunk<ReturnedType, ThunkArg>("/users/authentication", async (user) => {
try{
const res = await axios.post("/users/authentication", user)
...
} catch(err){
...
}
})
如果你使用 TypeScript,你总是应该在 genric 中为你的 asyncThunk 设置返回类型和参数
export const UserLogin = createAsyncThunk<return type, arguments>("/users/authentication", async (user) => { try{ const res = await axios.post("/users/authentication", user)... } catch(err){... } })
而且你还应该创建自定义钩子 useDispatch 和 useSelector
import { useSelector, useDispatch, TypedUseSelectorHook } from "react-redux"; import type { RootState, AppDispatch } from "../redux/store"; export const useAppDispatch = () => useDispatch<AppDispatch>(); export const useAppSelector: TypedUseSelectorHook<RootState> = useSelector;
主减速器文件应该有这样的样子:
import { configureStore } from "@reduxjs/toolkit"; import userleSlice from "./slice/userSlice"; export const store = configureStore({ reducer: { user: userSlice, }, }); export type RootState = ReturnType<typeof store.getState>; export type AppDispatch = typeof store.dispatch;
