使用异步数据和 axios 创建 Nuxt.js 列表

Question

I try to load data from Json to vue component using this tutorial:
https://nuxtjs.org/guide/async-data/

This is my code:

<li class="item" v-for="post in posts"  v-bind:key="post.id">
  <nuxt-link :to="....">
   {{post.id}}. {{post.title}}
  </nuxt-link>
</li>

import axios from "axios";
export default {
    async data () {
      let { data } = await axios.get(`http://jsonplaceholder/`)
      return { posts: data } // Console: property post is not defined
    }
  }

Tell me please, what's wrong?

Answer 1

You can do this based on Nuxt asyncData and the context guide, ie:

export default {
  async asyncData(context) {
    let response = await context.app.$axios.$get(`http://jsonplaceholder/`)
    return { posts: response } 
  }
}

Answer 2

according to nuxtjs document

  async asyncData ({ params }) {
    let { data } = await axios.get(`https://my-api/posts/${params.id}`)
    return { title: data.title }
  }

in your case this should be

async asyncData () {
    let { data } = await axios.get(`http://jsonplaceholder/`)
    return { posts: data } // Console: property post is not defined
}

Explaining more sid heart's reply: Function name is "asyncData" not async data. You are using async await you can use like this:

import axios from "axios";
export default {
  // Also define data function and define posts property
  data() {
    return {
      posts: {}
    }
  },

  async asyncData () {
    let { data } = await axios.get(`http://jsonplaceholder/`)
    return { posts: data } // Console: property post is not defined
   }
}
