node.js - 文件上传到 S3 - 0 字节

Question

我正在使用文本转 MP3 模块来创建文本转语音 MP3 文件。现在，该文件已成功保存到我的文件系统中。我也正在尝试将其上传到S3。它显示在 S3 中，但文件是空的(0 字节)。

txtomp3.getMp3(myverse, function(err, binaryStream){

  if(err){
    console.log(err);
    return;
  }
  var file = fs.createWriteStream("FileName.mp3"); // write it down the file
  file.write(binaryStream);
  file.end();

  var myfile = fs.createReadStream("FileName.mp3");

AWS.config.update({ accessKeyId: '...', secretAccessKey: '...' });

  var s3 = new AWS.S3();
  s3.putObject({
    Bucket: 'myverses',
    Key: 'del2.mp3',
    Body: myfile,
    ACL: 'public-read'
  },function (resp) {
    console.log(arguments);
    console.log('Successfully uploaded package.');
  });
  });
  });

Uploading a File to an Amazon S3 Bucket AWS 文档中有关于如何上传文件的清晰示例:

// Load the AWS SDK for Node.js
var AWS = require('aws-sdk');
// Set the region 
AWS.config.update({region: 'REGION'});

// Create S3 service object
s3 = new AWS.S3({apiVersion: '2006-03-01'});

// call S3 to retrieve upload file to specified bucket
var uploadParams = {Bucket: process.argv[2], Key: '', Body: ''};
var file = process.argv[3];

var fs = require('fs');
var fileStream = fs.createReadStream(file);
fileStream.on('error', function(err) {
  console.log('File Error', err);
});
uploadParams.Body = fileStream;

var path = require('path');
uploadParams.Key = path.basename(file);

// call S3 to retrieve upload file to specified bucket
s3.upload (uploadParams, function (err, data) {
  if (err) {
    console.log("Error", err);
  } if (data) {
    console.log("Upload Success", data.Location);
  }
});
