Vue.js:从api获取数据并将其传递给子组件(简单示例)

<template>
  <div>
    <h1>父组件</h1>
    <p>{{ data }}</p>
    <child-component :data="data"></child-component>
  </div>
</template>

<script>
import axios from 'axios';
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      data: null
    };
  },
  created() {
    axios.get('https://api.example.com/data')
      .then(response => {
        this.data = response.data;
      })
      .catch(error => {
        console.error(error);
      });
  }
};
</script>

<template>
  <div>
    <h2>子组件</h2>
    <p>{{ data }}</p>
  </div>
</template>

<script>
export default {
  props: ['data']
};
</script>
