无法从Fetch response.json（）返回JSON字段（但可以从console.log中看到它）

Question

I'm developing a Chrome extension and in my background.js i have a function

async function getData() {
  var resp = await (await fetch("https://www.example.com/json")).json();
  console.log(resp.field);
  alert(resp.field);
  return resp.field;
}

When i call the function ( var x = getData() ) alert and console.log show the content of the field (expected behavior), but then it returns a resolved Promise object. What am i missing?

Async functions always return promises . Your getData function simply wraps resp.field into a resolved promise.

getData().then(field => console.log(field))
