Vue.js 让 bootstrap vue 分页与 REST api 一起玩

试图让Bootstrap Vue使用REST api，该api返回一页的数据和记录总数(基于this):

<template>
  </div>
    <b-pagination 
      v-on:change="onPageChange" 
      :total-rows="totalRows" 
      :per-page="perPage" 
      v-model="currentPage"  />
    <b-table responsive striped hover show-empty
      stacked="md"
      :items="items"
      :fields="fields"
      :current-page="currentPage"
      :per-page="perPage"
      :filter="filter"
      :sort-by.sync="sortBy"
      :sort-desc.sync="sortDesc"
      :sort-direction="sortDirection"
      @filtered="onFiltered">
    </b-table>
  </div>
</template>
<script>
...
export default {
  name: 'TableList',
  data() {
    return {
      module: null,
      title: 'Table',
      items: [],
      fields: [],
      errors: [],
      currentPage: 1,
      perPage: 15,
      totalRows: 0,
      pageOptions: [ 5, 10, 15 ],
      sortBy: null,
      sortDesc: false,
      sortDirection: 'asc',
      filter: null,
    }
  },
  created() {
    ...
    this.fetch();
  },
  methods: {
    fetch() {
      var me = this;
      var requestParams = {
        page: this.currentPage,
        per_page: this.perPage
      };
      if(this.sortBy) {
        requestParams = Object.assign({ sort_by: this.sortBy }, requestParams);
      }
      Rest('GET', '/table/' + this.table, requestParams, this.$root.user.token)
      .then(response => {
        me.items = response.data[1]
        me.totalRows = response.data[0].total_entries
      })
      .catch(error => {
        this.errors.push('Error: ' + error.response.status + ': ' + error.response.statusText)
      })
      .finally(() => {
        //alert('turn off loader!');
      });
    }
  }
</script>

如果我拿到整张桌子，这个Vue就行了.然而，当我使用REST api一次返回一个页面时，页面数被计算为1，并且前向和结束链接处于非活动状态.因此，我无法触发请求，例如第2页.

REST api正确返回表中的总行数和请求的行数，但Bootstrap Vue似乎没有监视/响应对此的更改.全行.

我错过了什么？
