如何获取fetch的值呢

使用async/await方式获取fetch的值：

async function fetchData() {
  const response = await fetch('https://jsonplaceholder.typicode.com/todos/1');
  const data = await response.json();
  return data;
}

fetchData().then(data => {
  console.log(data);
});

使用Promise方式获取fetch的值：

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(data => console.log(data));
