老师您好!

**
vuex 使用模块
请问在state这里怎样使用 PartnerDataProps接口**

interface Icd {
  id: number
  name: string
  pcs: number
}

interface Ipartner {
  id: number
  create_time?: string
  update_time?: string
  cat_id: number
  cat_text: string
  grade_id: number
  grade_text?: string
  name: string
  linkman: string
  phone: string
  telephone: string
  address: string
  memo: string
  status: number
  status_text: string
  delete_time?: null | string
}

export interface PartnerDataProps {
  cat: Icd[]
  grade: Icd[]
  partner: Ipartner[]
}

// 老师您好，请问在state这里怎样使用 PartnerDataProps接口
const state = () => ({
  cat: [],
  grade: [],
  partner: [],
})

const mutations = {
  fetchCat(state, rawData) {
    state.cat = rawData.data
  },
  fetchGrade(state, rawData) {
    state.grade = rawData.data
  },
  fetchPartners(state, rawData) {
    state.partner = rawData.data
  },
}

const actions = {
  fetchCat(context) {
    axios.get('api/partner/cat').then((res) => {
      context.commit('fetchCat', res.data)
    })
  },
  fetchGrade(context) {
    axios.get('api/partner/grade').then((res) => {
      context.commit('fetchGrade', res.data)
    })
  },
  fetchPartners(context) {

      return dispatch('fetchGrade').then(() => {
        return dispatch('fetchPartners')
      })
    })
