谁能告诉我为什么我在控制台中收到 404 错误？

Question

I'm making an api call to the rescountries api. When I open up the console. I get the following error "Failed to load resource: the server responded with a status of 404 (Not Found)" However I seem to be getting an object printed out in the console that's coming from the restcountries api via the "console.log(data)" line. Is it to do with the API itself or something I did in my code? Thanks in advance.

"use strict";

const btn = document.querySelector(".btn-country");
const countriesContainer = document.querySelector(".countries");

const getCountryData = function (country) {
  const request = new XMLHttpRequest();
  request.open("GET", `https://restcountries.com/v3.1/name/${country}`); 
  request.send();
request.addEventListener("load", function () {
    const [data] = JSON.parse(this.responseText); 
    console.log(data);
    const html = `<article class="country">
    <img class="country__img" src="${data.flag}"/>
    <div class="country__data">
      <h3 class="country__name">${data.name}</h3>
      <h4 class="country__region">${data.region}</h4>
      <p class="country__row"><span>👫</span>${(
        +data.population / 100000
      ).toFixed(1)}</p>
      <p class="country__row"><span>🗣️</span>${data.languages.eng}</p>
      <p class="country__row"><span>💰</span>${data.currencies.symbol}</p>
    </div>
  </article>
  `;
    countriesContainer.insertAdjacentHTML("beforeend", html);
    countriesContainer.lastElementChild.opacity = 1;
  });
};


getCountryData("GB");
getCountryData("usa");

You have 404 error because you have following divs <img class="country__img" src="🇺🇸"> The src attribute should be an URL - not a symbol. You have 2 calls one for UK and one for USA so you will have 2 such images and 2 404 Not found errors will appear.

So your line of code where you produce this image ie <img class="country__img" src="${data.flag}"/> should be probably <div>${data.flag}</div> or similar.

Example:

 "use strict"; const btn = document.querySelector(".btn-country"); const countriesContainer = document.querySelector(".countries"); const getCountryData = function (country) { const request = new XMLHttpRequest(); request.open("GET", `https://restcountries.com/v3.1/name/${country}`); request.send(); request.addEventListener("load", function () { const [data] = JSON.parse(this.responseText); console.log(data); const html = `<article class="country"> <div class="country__img">${data.flag}</div> <div class="country__data"> <h3 class="country__name">${data.name}</h3> <h4 class="country__region">${data.region}</h4> <p class="country__row"><span>👫</span>${( +data.population / 100000 ).toFixed(1)}</p> <p class="country__row"><span>🗣️</span>${data.languages.eng}</p> <p class="country__row"><span>💰</span>${data.currencies.symbol}</p> </div> </article> `; countriesContainer.insertAdjacentHTML("beforeend", html); countriesContainer.lastElementChild.opacity = 1; }); }; getCountryData("GB"); getCountryData("usa");

 <div class="countries"></div>
