Javascript Node.js上传到Amazon S3正常，但文件损坏

我通过我的CMS提交了一份表格，其中包含一个图像和一些文本的文件选择器。代码运行&在我的S3帐户中创建了一个名称正确但已损坏的对象。例如，我正在上传JPG图像，但当我在s3仪表板中查看它们时，我只看到一个黑屏

非常感谢您的帮助

我的HTML表单：

更新

我相信您需要传递流而不是文件路径，您可以像这样使用fs.createReadStream：

router.post('/updateschedule', isLoggedIn, upload.single('schedulepicture'), function(req, res) {
  var scheduleImageToUpload;

  //Check if image was uploaded with the form & process it
  if (typeof req.file !== "undefined") {

    //Create Amazon S3 specific object
    var s3 = new aws.S3();
    var stream = fs.createReadStream(req.file.path)

    //This uploads the file but the file cannot be viewed.
    var params = {
      Bucket: S3_BUCKET,
      Key: req.file.originalname, //This is what S3 will use to store the data uploaded.
      Body: stream, //the actual *file* being uploaded
      ContentType: req.file.mimetype, //type of file being uploaded
      ACL: 'public-read', //Set permissions so everyone can see the image
      processData: false,
      accessKeyId: S3_accessKeyId,
      secretAccessKey: S3_secretAccessKey
     }

    s3.upload( params, function(err, data) {
      if (err) {
        console.log("err is " + err);
      }
      res.redirect('../adminschedule');
    });
  }
});
