Passing Data in asyncData Nuxt.js

问题

I'm new to nuxt.js and I want to ask if there is any way to pass data in asyncData. Here is the code.

    <script type="text/javascript">
  import axios from 'axios'
  export default {
    data(){
        return {
          sample: 'asdf',
          baseUrl: 'https://jsonplaceholder.typicode.com/posts/1'
        }
    },
    async asyncData ({ params }) {
      let { data } = await axios.get(this.baseUrl)
      return { title: data}
    }
}
</script>

I know you don't have access to this but is there a way to pass data. Thanks.

回答1:

Usually this kind of configuration like baseurl defined in env vars in nuxt. Docs

  // nuxt.config.js
  env: {
    baseUrl: process.env.BASE_URL || 'http://localhost:3000'
  }

Then you can access it anywhere via process.env e.g. in asyncData

async asyncData ({ params }) {
  let { data } = await axios.get(process.env.baseUrl)
  return { title: data}
}

But for baseUrl for axios you can just define it once e.g. in plugins/axios and then import from there

import axios from 'axios'

export default axios.create({
  baseURL: process.env.baseUrl
})

Or you can use @nuxt/axios module where u can set baseUrl as an configuration option
