如何在打字稿中使用 Nuxt fetch() 钩子？

Question

如何使用 fetch 钩子？

脚本有效，但打字稿编译器报告错误。

<script lang="ts">
import Vue from 'vue'
import Component from 'vue-class-component'
@Component({
  components: {ValidationProvider, ValidationObserver},
  async fetch() {
    const winnerProcessService = new WinnerProcessService(this.$route)
    this.winner = await winnerProcessService.findWinner()
  }
})
export default class winPayClient extends Vue {
  winner: Winner = winnerInitialiser

Typescript 设置为严格

ERROR  ERROR in client/pages/index.vue:163:10

163 | this.winner = await WinnerProcessService.findWinner() | ^^^^^^^
