如何将服务器端 JSON 传递/导入到 vue 应用程序？

Question

I'm building a webapp that requires a JSON file as data. The person using my app in their website should be able to pass in a JSON file hosted on their server so that my app can read it.

In development, I just used import mydata from "./mydata.json" , but this won't work in production. I tried to have a computed property that returns require (this.publicPath + this.datapath) (where this.publicPath is process.env.BASE_URL , but it's not able to find the file (if it's relevant, I'm using vue-cli to build).

The structure of my app is that I have a wrapper App.vue and then the main component, main-component.vue (so that I can pass a prop containing data to the main component).

What's the best way to do this? I've tried using a <script> tag in index.html , but apparently that's not supported with JSON. I don't want to use other libraries like jQuery.

(I'm thinking that I could have the user just import their file with the ES6 syntax by creating a new Vue component/app, but I'm not sure how to do that in pure HTML).

If you can try using a.js file that migh work and you can structure the data the same way as in a.json file, afterall a json is just a js object, also i had this problem while doing the same thing. DISCLAIMER: you might have to restructure your data to be in an exported variable if that is possible, like so:

export const myObj = {your json}

As an extension of my comment: what you're looking for is to actually fetch the JSON from your server using an XMLHttpRequest. You can do this in a modern, ES6-manner using the Fetch API :

fetch('/path/to/your/json')
  .then(resp => resp.json())
  .then(data => {
    // Access the parsed JSON as `data`
    console.log(data);
  });
