javascript - 我无法返回 axios 请求的响应

Question

我正在尝试在 Node 中创建一个模块，以使用 axios 请求从 API 返回 json。但是当我尝试从函数 getJson() 返回响应时，什么也没有返回给我。

const axios = require('axios');
const authentication = require('./authentication');


const url = `https://api.codenation.dev/v1/challenge/dev-ps/generate-data?token=${authentication.token}`;

const getJson = async () => {
  const response = await axios.get(url);
  // Here i can see the json normally
  console.log(response.data)
  return response.data
}

const response = getJson()
// but here nothing is shows to me in console.
console.log(response)

return of console

Answer 1

getJson() 实际上返回 promise实例。您只需要等待，例如:

(async () => {
  const response = await getJson()
  console.log(response)
})();
