Redux combineReducers() 无法识别状态

Redux combineReducers() isn't recognising state

我正在使用 redux combineReducers() 组合 2 个减速器。虽然它们都在开发工具中被识别,但其中一个只是一个空对象,即使我将具有不同属性的对象传递给 reducer。

combineReducers() 文件:

import { combineReducers } from 'redux'
import { default as JobReducer } from './Jobs/reducer'
import { default as AuthReducer } from './Auth/reducer'

const RootReducer = combineReducers({
    job: JobReducer,
    auth: AuthReducer,
})

export default RootReducer

第一个减速器:

import { SINGLE_JOB_POST_SUCCESS } from './constants'

const initial = {
    jobs: [],
    job: {}
}

export default (state = initial, action) => {
    const { type, payload } = action
    switch (type) {
        case SINGLE_JOB_POST_SUCCESS:
            return {
                ...state,
                jobs: [
                    ...state.jobs,
                    ...payload
                ]
            }
        default:
            return {}
    }
}

第二个减速机:

import { RESET_AUTH_RESPONSE } from './constants'

const initial = {
    authResponse: null,
    user: {}
}

export default (state = initial, action) => {
    const { type, payload } = action
    switch (type) {
        case RESET_AUTH_RESPONSE:
            return {
                ...state,
                authResponse: null
            }
        default:
            return state
    }
}

当我在 redux 开发工具中查看状态时,“auth”具有相关属性,但“job”只是一个空对象。我已将 reducer 文件命名为不同的名称,以消除对别名的需要,但它没有效果。感谢任何帮助。

因为您的 authReducer 有:

        default:
            return {}

因此,只要它看到无法识别的操作,它就会 return 一个空对象。您需要将其设为 return state

此外,请注意,您应该改用 our official Redux Toolkit package,这将大大简化您的 Redux 逻辑。
