Is it possible to upload to AWS S3 with checksum enabled?

wanghq · November 7, 2022, 7:53pm

I generate the presigned S3 PUT url and use Uppy to upload (not multi-part upload) file. I wonder if there is an option to enable integrity check.

Thanks!

AFAIK you can calculate that yourself and send it as a header, as long as you enabled it in S3:

github.com

transloadit/uppy/blob/cc4c52af6ccbc8c8e57d572fed83cf5b870090a2/examples/aws-nodejs/public/index.html#L42


      
                  // Parse the JSON response.
                  return response.json()
                }).then((data) => {
                  // Return an object in the correct shape.
                  return {
                    method: data.method,
                    url: data.url,
                    fields: data.fields, // For presigned PUT uploads, this should be left empty.
                    // Provide content type header required by S3
                    headers: {
                      'Content-Type': file.type,
                    },
                  }
                })
              },
          });
          
          
uppy.on('complete', (result) => {
            console.log('Upload complete! We’ve uploaded these files:', result.successful)
          })
