Question

所以我有一堆鸭子样式的redux模块看起来像这样：

import { createAction, handleActions } from 'redux-actions'

const SET = "error/SET"
const CLEAR = "error/CLEAR"

export default handleActions({
  SET: (error, action) => action.payload,
  CLEAR: (error, action) => ""
}, "")

export const setError = createAction(SET)
export const clearError = createAction(CLEAR)

然后，在reducers.js中我这样做：

import error from './error'

export default combineReducers({
  error,
  ...
})

然而，当我发送（setError（＆＃34; ERROR＆＃34;））时，我看到redux devtools中的动作，但状态没有改变

您正在将包含错误密钥的地图传递给handleActions。您不希望密钥为SET和CLEAR，而是取其值（error/SET和error/CLEAR）。为此，你必须将它们包在方括号中：

export default handleActions({
  [SET]: (error, action) => action.payload,
  [CLEAR]: (error, action) => ""
}, "")

redux-actions handleActions不会改变状态
