methods: { // 按钮点击事件 显示新增编辑弹窗组件 show() { this.addOrUpdateVisible = true; }, showAddOrUpdate(data) { if (data === "false") { this.addOrUpdateVisible = false; } else { this.addOrUpdateVisible = true; } }, // 确认删除 handleConfirm() { var params = this.id deleteCategory(params).then((res) => { if (res.data.state === '200') { this.$router.push({ path: "/" }); } }) }, // 接收路由跳转传来的id getId() { this.id = this.$route.query.id }, // 获取新的页数 getNewPage(val) { this.currentPage = val }, // 分页获取帖子 getArticleByPage() { var params = { currentPage: this.currentPage, pageSize: this.pagesize, categoryId: this.$route.query.id, source: this.source, parameter: this.parameter } getArticlePage(params).then((res) => { }) }, //路由跳转到帖子详情界面 Articli_detail(item) { this.$router.push({ path: "/articledetail", query: { id: item.id } }) }, // 置顶帖子 handleTop(item) { var params = { articleId: item.id, categoryId: this.$route.query.id, top: true } topArticle(params).then((res) => { }) }, }, watch: { currentPage() { this.getArticleByPage() } }, beforeCreated() { this.getNewPage() }, created() { this.getId() this.getArticleByPage() }, };请将代码用async和await改写

你可以使用async和await来改写这段代码。下面是改写后的代码：

methods: {
  show() {
    this.addOrUpdateVisible = true;
  },
  showAddOrUpdate(data) {
    if (data === "false") {
      this.addOrUpdateVisible = false;
    } else {
      this.addOrUpdateVisible = true;
    }
  },
  async handleConfirm() {
    var params = this.id;

    try {
      const res = await deleteCategory(params);
      if (res.data.state === '200') {
        this.$router.push({ path: "/" });
      }
    } catch (error) {
      console.error(error);
    }
  },
  getId() {
    this.id = this.$route.query.id;
  },
  getNewPage(val) {
    this.currentPage = val;
  },
  async getArticleByPage() {
    var params = {
      currentPage: this.currentPage,
      pageSize: this.pagesize,
      categoryId: this.$route.query.id,
      source: this.source,
      parameter: this.parameter
    };

    try {
      await getArticlePage(params);
    } catch (error) {
      console.error(error);
    }
  },
  Articli_detail(item) {
    this.$router.push({ path: "/articledetail", query: { id: item.id } });
  },
  async handleTop(item) {
    var params = {
      articleId: item.id,
      categoryId: this.$route.query.id,
      top: true
    };

    try {
      await topArticle(params);
    } catch (error) {
      console.error(error);
    }
  }
},
watch: {
  async currentPage() {
    await this.getArticleByPage();
  }
},
async beforeCreate() {
  await this.getNewPage();
},
async created() {
  await this.getId();
  await this.getArticleByPage();
}

通过将异步操作使用async和await包裹，并使用try-catch语句处理错误，可以更清晰地编写异步代码。同时，将beforeCreated和created生命周期钩子函数声明为async，并使用await等待异步操作完成。
