添加getters

配置   SET_****   comit（   ） 俩个地方

import { login, logout, getInfo } from '@/api/user'
import { getToken, setToken, removeToken } from '@/utils/auth'
import { resetRouter } from '@/router'

const getDefaultState = () => {

  }
}

export default {
  namespaced: true,
  state,
  mutations,
  actions,

}

调用

  <div>
      <p>个人信息</p>
      <p>{{name}}</p>
      <p>{{roles}}</p>
      <p>{{avatar}}</p>
      <p>{{id}}</p>
  </div>

  
</template>

<script>
import { mapGetters } from 'vuex'
import sysadmin from '@/api/sys/sysadmin'
export default {
  name: 'Dashboard',
  computed: {
    ...mapGetters([
      'name',
      'roles',
      'avatar',
      'id'
    ])
  },
