如何在Promise.all中从多个端点获取多个多个数据？

const endpoint1 = 'https://api.example.com/data1';
const endpoint2 = 'https://api.example.com/data2';
const endpoint3 = 'https://api.example.com/data3';

const request1 = fetch(endpoint1);
const request2 = fetch(endpoint2);
const request3 = fetch(endpoint3);

Promise.all([request1, request2, request3])
  .then(responses => {
    // 处理所有请求的响应数据
    const data1 = responses[0].json();
    const data2 = responses[1].json();
    const data3 = responses[2].json();

    return Promise.all([data1, data2, data3]);
  })
  .then(data => {
    // 处理所有数据
    const result1 = processData1(data[0]);
    const result2 = processData2(data[1]);
    const result3 = processData3(data[2]);

    console.log(result1, result2, result3);
  })
  .catch(error => {
    // 处理错误
    console.error(error);
  });
