javascript - Amazon s3 Node 文件上传错误

Question

我在 amazon s3 中上传文件时出错。 代码如下:

        const s3 = require('s3');  const client = s3.createClient({
             maxAsyncS3: 100,
             s3RetryCount: 3,
             s3RetryDelay: 30000,
             multipartUploadThreshold: 20971520,
             multipartUploadSize: 15728640,
             s3Options: {
                 accessKeyId: "xxxx",
                 secretAccessKey: "yyyy",
                 region: "us-east-2",
             },    });
            const params = {
             localDir: "file-path",
             s3Params: {
               Bucket: "bucket-name",
               Prefix: "images/image.jpg"
             },    };    
          const uploader = client.uploadDir(params); 
       uploader.on('error', (err) => {
             console.error("unable to upload:", err.stack);  
      });    
uploader.on('progress', () => {
             console.log("progress", uploader.progressMd5Amount,
                       uploader.progressAmount, uploader.progressTotal);    });    
uploader.on('end', () => {
             console.log("done uploading");    });

我得到的错误是:

unable to upload: Error: Non-file stream objects are not supported with SigV4 in AWS.S3

您应该向上传方法传递一个文件。 这是一个例子:

  var file = files[0];
  var fileName = file.name;
  var albumPhotosKey = encodeURIComponent(albumName) + '//';

  var photoKey = albumPhotosKey + fileName;
  s3.upload({
    Key: photoKey,
    Body: file,
    ACL: 'public-read'
  }, function(err, data) {
    if (err) {
      return alert('There was an error uploading your photo: ', err.message);
    }
    alert('Successfully uploaded photo.');
    viewAlbum(albumName);
  });
}
