调用接口 Promise.all的简单使用方式

created() {
  const requests = [
    axios.get('/api/data1'),
    axios.get('/api/data2'),
    axios.get('/api/data3')
  ];

  Promise.all(requests)
    .then(responses => {
      // 处理响应数据
      const data1 = responses[0].data;
      const data2 = responses[1].data;
      const data3 = responses[2].data;
      // ...
    })
    .catch(error => {
      console.log(error);
    });
}
