nodejs 获取 API 返回相同的 JSON 文件

Question

我正在尝试通过构建自己的 rest API 来学习 nodejs。

我从https://sweetalert.js.org/guides/#getting-started复制了这段代码：

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();
  }
});

我正在尝试使用 nodejs 进行fetch 。

为此，我改变了行

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

进入

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

（我将应用程序设置为侦听端口 3000）。

在我的 nodejs 文件中，我添加了一个 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();
    }
});

问题是，无论我输入什么作为输入，我都会得到相同的 JSON 文件。

我对nodejs很陌生，感谢所有帮助！

JSON 文件，我不断收到任何输入（例如http://localhost:3000/search?movie_name=bob ）：

定义

Answer 1

似乎错字：而不是用name调用查询，而是用movie_name调用。 与req.query.name; 在快递 js 中。

浏览器

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

快递：

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