Shopify script_tag API -如何传递变量？

var myVariable = "Hello, Shopify!";

const shopifyAPIEndpoint = 'https://your-shopify-store.myshopify.com/admin/api/2021-07';
const accessToken = 'your-access-token';

const scriptUrl = 'https://your-server.com/path/to/your/javascript-file.js';

const scriptTagData = {
  script_tag: {
    event: 'onload',
    src: scriptUrl
  }
};

fetch(`${shopifyAPIEndpoint}/script_tags.json`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-Shopify-Access-Token': accessToken
  },
  body: JSON.stringify(scriptTagData)
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

console.log(myVariable); // 输出：Hello, Shopify!
