Javascript redux中的localStorage reducer错误

嗨，我有启动会话的代码，我需要在登录后将用户的信息保存在localStorage中

    'use strict';
    const defaultState ={
        permission: localStorage.getItem('email') ? localStorage.getItem('email') : null

     }

    export const signInReducer = (state=defaultState, action)=>{
        switch (action.type){
            case 'SIGNIN_REQUEST':
                return state;
            case 'SIGNIN_FAILURE':
                return state;
            case 'SIGNIN_SUCCES':
                return Object.assign({}, state, {

                    permission: action.payload.email ? JSON.stringify(action.payload.email) : null

                })

            default:
                return state;
        }
}

感谢您的帮助

您不应该在还原程序中保存到

localStorage

。这些应该是纯的，没有副作用

尝试在动作创建者中执行此操作：

const signInSucess = (user) => {
  localStorage.setItem('permission', user)
  //your code...
  return { type: "SIGNIN_SUCCES", payload: user }
}

localStorage.setItem

hi，但不要将信息保存到localStorage中的用户
