javascript - CreateAsyncThunk 错误 : Actions must be plain objects. 使用自定义中间件进行异步操作

Question

我目前正在设置我的 RTK (Redux Toolkit) 并进行了一些小测试。这是我的代码:
存储/index.js

import { configureStore } from '@reduxjs/toolkit'
import { loginSliceReducer } from './views/page/login/loginSlice'

export default configureStore({
  reducer: {
    login: loginSliceReducer
  }
})

loginSlice.js

import { createSlice, createAsyncThunk } from '@reduxjs/toolkit'
import ApiService from '../../services/ApiService'

export const authorize = createAsyncThunk(
  'api/authorize',
  async (email, password) => {
    const response = await ApiService.post(email, password)
    return response.data
  }
)

export const loginSlice = createSlice({
  name: 'login',
  initialState: {
    loading: true,
    token: null,
    data: []
  },
  reducers: {
    updateState: (state, action) => {
      const { payload } = action
      switch (payload.type) {
        case AUTH_SUCCESS:
          state.loading = false
          state.token = payload.token
          state.data = payload.data
          break
        default:
      }
    }
  },
  extraReducers: {
    [authorize.fulfilled]: (state, action) => {
      // ... do state update here
    }
  }
})

export default loginSlice.reducer

login.js

import React, { useEffect } from 'react'
import { useSelector, useDispatch } from 'react-redux'
import { authorize } from './loginSlice'

const Login = () => {
  const dispatch = useDispatch()
  useEffect(() => {
    dispatch(authorize('testuser@example.com', 'test123'))
  }, [])

  return <div>Auth Test</div>
}

上面的代码不起作用。我不断收到此错误: Error: Actions must be plain objects. Use custom middleware for async actions.在这条线上: > 25 | dispatch(authorize('testuser@example.com', 'test123'))请不要介意我在 useEffect 上触发授权，因为这只是检查是否正在调用端点以及检查请求成功后状态是否会更新的测试。 :-D

我遇到了同样的问题，这是由于我添加了额外的中间件造成的。@reduxjs/toolkit的configureStore有一些默认包含的中间件，但如果你添加任何东西到 middleware属性，它将覆盖这些默认值。
解决方案是包含默认中间件以及您定义的中间件:

import { configureStore, getDefaultMiddleware } from '@reduxjs/toolkit';

import { loginSliceReducer } from './views/page/login/loginSlice';
import { otherMiddleware } from './middlewares/some-other-module';

export default configureStore({
  reducer: {
    login: loginSliceReducer
  },
  middleware: [ // Because we define the middleware property here, we need to explictly add the defaults back in.
    ...getDefaultMiddleware(),
    otherMiddleware
  ]
})

注意，没有必要明确包含 redux-thunk使用 @reduxjs/toolkit 时因为它已经是 getDefaultMiddleware() 的默认中间件的一部分
