问尝试在第二个函数中使用response.json来筛选特定的结果

EN

import fetch from "node-fetch";

const URL_API = `https://jsonmock.hackerrank.com/api/countries?`;
async function getResponse() {
  let response = await fetch(URL_API, {
    method: "GET",
    headers: {
      "Content-type": "application/json",
    },
  })
    .then((response) => {
      return response.json();
    })
    .then((data) => {
      console.log(data);
    })
    .catch((error) => {
      // handle error
      console.error(`The unknown error has occurred: ${error}`);
    });
}

getResponse();

async function getCapitalCity(country) {
  const data = await response.json(); //error mentioned here
  for (let info in data) {
    console.log(info);
    if (info.name === country) {
      return info.capital;
    } else {
      return -1;
    }
  }
}

console.log(getCapitalCity("Afghanistan"));
