Vue.js中如何通过两个接口渲染表格数据并进行数据格式化？

<code class="javascript"><template>
  <table>
    <thead>
      <tr>
        <th>Port ID</th>
        <th>Rate</th>
        <th>Throughput</th>
        <th>Formatted Frequency</th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="item in tableData" :key="item.portId">
        <td>{{ item.portId }}</td>
        <td>{{ item.rate }}</td>
        <td>{{ item.thruput }}</td>
        <td>{{ item.formattedFrequency }}</td>
      </tr>
    </tbody>
  </table>
</template>

<script>
import api from './api'; // 假设api.js包含你的API调用函数

export default {
  data() {
    return {
      tableData: [],
      additionalData: {}
    };
  },
  mounted() {
    this.fetchData();
  },
  methods: {
    async fetchData() {
      try {
        const [mainData, extraData] = await Promise.all([
          api.GetSerialId(),
          api.GetFrequencyData() // 假设这是第二个接口
        ]);
        this.tableData = mainData.data.port_thruput.split(',').map((item, index) => {
          if (index % 3 === 0) {
            const [portId, rate, thruput] = mainData.data.port_thruput.split(',').slice(index, index + 3);
            return { portId, rate, thruput };
          }
          return null;
        }).filter(item => item !== null);

        this.formatAdditionalData(extraData.data);
      } catch (error) {
        console.error('Error fetching data:', error);
      }
    },
    formatAdditionalData(data) {
      const entries = Object.entries(data);
      const filteredData = entries.filter(([key, value]) => value !== 0);
      const formatted = filteredData.map(({ key, value }) => {
        return `${key.replace("_FREQ", "").toUpperCase()}/${value}`;
      });
      this.tableData = this.tableData.map(item => ({
        ...item,
        formattedFrequency: formatted.join('; ')
      }));
    }
  }
};
</script></code>
