Encountered 500 (RuntimeError) error while re-fetching data: problem solution for axios and nuxtjs

Question

I built a blog-based page using WordPress as API and Nuxt.js as JavaScript framework. The problem occurs in my _slug.vue file. When I navigate to an individual blog (project) page, the individual blog posts render fine. However, if I reload a single blog post page, or just enter in the URL, the console shows the error: GET url 500 (RuntimeError).

<template>
<div class="single-project">
    <Header />
    <h1>{{project.title.rendered}}</h1>
    <article v-html="project.content.rendered"></article>
    <ClickToAction />
</div>

<script>
/* eslint-disable */
import axios from 'axios'
export default{
    data() {
        return {
            project: {}
        }
    },
    async asyncData({params}){

            return await axios.get('https://my-api.wp/wp-json/wp/v2/project/'   params.id)
                .then((res) => {
                    return {
                        project: res.data
                    }
                }).catch(function (error) {
                    if (error.response) {
                    // Request made and server responded
                    console.log(error.response.data);
                    console.log(error.response.status);
                    console.log(error.response.headers);
                    } else if (error.request) {
                    // The request was made but no response was received
                    console.log(error.request);
                    } else {
                    // Something happened in setting up the request that triggered an Error
                    console.log('Error', error.message);
                    }
                });
    }
}
</script>

以及一个项目的链接：

<nuxt-link :class="'item '   project._embedded['wp:term'][0].map(el => el.name.toLowerCase()).join(' ')" v-for="project in projects"  :key="project.id" :to="{name: 'projekte-slug', params: { slug: project.slug, id: project.id}}">

目标在nuxt.config.js中是静态的。

编辑

经过研究，我发现在nuxt-link的params对象中传递的id在重新加载后丢失，因为它需要“父”页面来获取id的值。为了解决这个问题，我通过API使用slug获取了项目，并显示了所有属性（例如标题、内容等）

async asyncData({ params, $axios }) {
        try {
            console.log(params.slug);
            const project = await $axios.$get(`https://my-api.wp/wp-json/wp/v2/project?slug=${params.slug}&_embed`)
            return { project }
        } catch (error) {
...
}

asyncData will not be retriggered when refreshing the page or entering the URL directly.
If you want to get data when these events occur, you can use fetch()hook or middleware.

Edited answer

Before continuing, please make sure you have @nuxtjs/axios installed: https://axios.nuxtjs.org/setup

<script>
export default {
  async asyncData({ params, $axios }) {
    try {
      const project = await $axios.$get(`https://my-api.wp/wp-json/wp/v2/project/${params.id}`)
      return { project }
    } catch (error) {
      if (error.response) {
        // Request made and server responded
        console.log(error.response.data)
        console.log(error.response.status)
        console.log(error.response.headers)
      } else if (error.request) {
        // The request was made but no response was received
        console.log(error.request)
      } else {
        // Something happened in setting up the request that triggered an Error
        console.log('Error', error.message)
      }
    }
  },
}
</script>
