nodejs 獲取 API 返回相同的 JSON 文件

Question

我正在嘗試通過構建自己的 rest API 來學習 nodejs。

我從https://sweetalert.js.org/guides/#getting-started復制了這段代碼：

swal({
  text: 'Search for a movie. e.g. "La La Land".',
  content: "input",
  button: {
    text: "Search!",
    closeModal: false,
  },
})
.then(name => {
  if (!name) throw null;

  return fetch(`https://itunes.apple.com/search?term=${name}&entity=movie`);
})
.then(results => {
  return results.json();
})
.then(json => {
  const movie = json.results[0];

  if (!movie) {
    return swal("No movie was found!");
  }

  const name = movie.trackName;
  const imageURL = movie.artworkUrl100;

  swal({
    title: "Top result:",
    text: name,
    icon: imageURL,
  });
})
.catch(err => {
  if (err) {
    swal("Oh noes!", "The AJAX request failed!", "error");
  } else {
    swal.stopLoading();
    swal.close();
  }
});

我正在嘗試使用 nodejs 進行fetch 。

為此，我改變了行

return fetch(`https://itunes.apple.com/search?term=${name}&entity=movie`);

進入

return fetch('http://localhost:3000/search?movie_name=' + name, {
                method: 'GET'
            });

（我將應用程序設置為偵聽端口 3000）。

在我的 nodejs 文件中，我添加了一個 GET 路由：

app.get('/search', async function(req, resp) {
    try {
        let name = req.query.name;
        let response = await fetch('https://itunes.apple.com/search?term=' + name + '&entity=movie');
        let body = await response.text();
        let json = JSON.parse(body);
        resp.status(200).send(json);
    } catch (error) {
        resp.status(500).send();
    }
});

問題是，無論我輸入什么作為輸入，我都會得到相同的 JSON 文件。

我對nodejs很陌生，感謝所有幫助！

JSON 文件，我不斷收到任何輸入（例如http://localhost:3000/search?movie_name=bob ）：

定義

Answer 1

似乎錯字：而不是用name調用查詢，而是用movie_name調用。 與req.query.name; 在快遞 js 中。

瀏覽器

return fetch('http://localhost:3000/search?movie_name=' + name, {
                method: 'GET'
            });

快遞：

app.get('/search', async function(req, resp) {
    try {
        let name = req.query.name;
