从链接下载文件并检查下载是否完成nodejs

Question

我尝试从链接下载文件

这是我的代码

  const url ="https://lalalai.s3-us-west-2.amazonaws.com/media/split/a703a60c-54f3-48f4-91b5-43a60c-54f3-48f4-91b5-4b3bc71dfd2f/accompaniment";
  const file = fs.createWriteStream("./uploads/exp.mp3");
  https.get(url, async function (response) {
    await response.pipe(file);
    console.log("done");
  });

问题是，服务器返回“完成”但下载的文件仍未完成。 有人能帮我吗？谢谢：D

我认为您可以监听事件并应用回调来了解该特定事件会发生什么。下面是示例代码。

const url ="https://lalalai.s3-us-west-2.amazonaws.com/media/split/a703a60c-54f3-48f4-91b5-43a60c-54f3-48f4-91b5-4b3bc71dfd2f/accompaniment";
  const file = fs.createWriteStream("./uploads/exp.mp3");
  https.get(url, async function (response) {
    response.pipe(file);
    console.log("downloading started");

    response.on("error", (err) => {
      console.log("some error occurred while downloading");
      throw err;
    });
  
    response.on("end", () => {
      console.log("it worked, download completed");
    });
    
 });

有时正在下载的文件会出现在 response.body 中而不是 response 中，所以如果上述方法不起作用，请检查一下。
