在响应节点JS之前，等待文件上载到firebase中[重复]

Question

嗨，我想在文件上传到firebase后立即返回响应我可以上传，但我想在返回响应之前上传文件

const file = bucket.file(`equipo_${idEquipo}`);
  const fileStream = file.createWriteStream({ resumable: false });
  fileStream.end(newImg.buffer);
  fileStream.on("error", err => console.log(err));
  fileStream.on("finish", () => {
  }); 
return response;

Answer 1

您已经有了filestram回调，所以

const file = bucket.file(`equipo_${idEquipo}`);
 const fileStream = file.createWriteStream({ resumable: false });
fileStream.end(newImg.buffer);
fileStream.on("error", err => console.log(err));
fileStream.on("finish", (response) => {
return response;
});
