TypeScript:
发出 HTTP 请求

// TypeScript 示例：发送 GET 请求来获取数据
async function getData(url: string): Promise<any> {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    return await response.json();
  } catch (error) {
    console.error('Fetching data failed:', error);
  }
}

// 使用示例
const url = 'https://jsonplaceholder.typicode.com/todos/1';
getData(url).then(data => console.log(data));

// 输出样例：
// {
//   userId: 1,
//   id: 1,
//   title: 'delectus aut autem',
//   completed: false
// }
