        >
        </el-pagination>

1.2 Logic

    data() {
      return {
        //请求参数
        queryInfo: {
          type: 3,
          //当前页数
          pagenum: 1,
          //指定当前页数显示的数目
          pagesize: 5,
        },
        goodsList: [],
        //总数据
        total: 0,
      }
    }

  methods: {
      //获取商品分类数据
      async getGoodsCate() {
        const { data: res } = await this.$http.get("categories", {
          params: this.queryInfo,
        })
        if (res.meta.status !== 200) {
          this.$message.error("获取参数失败")
        }
        this.total = res.data.total
        this.goodsList = res.data.result
        //console.log(this.goodsList)
      },
      //监听每页的条数
      handleSizeChange(pagesize) {
        // console.log(`每页 ${val} 条`)
        this.queryInfo.pagesize = pagesize
        this.getGoodsCate()
      },
      //监听当前页数
      handleCurrentChange(pageNum) {
        this.queryInfo.pagenum = pageNum
