Amazon S3 bucket MalformedXML error when uploading
15,835
It looks like you're sending the PUT request to the bucket itself, without an object name. S3 interprets this as a PUT BUCKET request, and expects the body to be a CreateBucketConfiguration XML document.
To upload a file, your XHR open call should look more like:
xhr.open('PUT', 'https://bucket-name.s3.amazonaws.com/' + filename, true);
There's an example request in the documentation.

I am trying to upload a picture to my Amazon S3 bucket. Here is the code for my XMLHttpRequest:
var form_data = new FormData(); form_data.append(filename, file); var xhr = new XMLHttpRequest(); xhr.open('PUT', 'https://bucket-name.s3.amazonaws.com', true); xhr.send(form_data);
I have configured the CORS to be as follows:
<CORSConfiguration> <CORSRule> <AllowedOrigin>http://localhost:3000</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <AllowedMethod>PUT</AllowedMethod> <AllowedMethod>POST</AllowedMethod> <AllowedMethod>DELETE</AllowedMethod> <AllowedHeader>*</AllowedHeader> </CORSRule> </CORSConfiguration>
Unfortunately, I keep getting the following error when I attempt to upload to it:
PUT https://bucket-name.s3.amazonaws.com 400 (Bad Request) <?xml version="1.0" encoding="UTF-8"?> <Error><Code>MalformedXML</Code><Message>The XML you provided was not well-formed or did not validate against our published schema</Message><RequestId>6188AA51D1EE6B38</RequestId> <HostId>f3d5Aj8bMyMOJywRnYKH/tBXRHCDWFvNzcb4ejs9F4/IulP1P2n0XoN1mDq7LpQgL/RIsW1c6RA=</HostId></Error>
Does anyone know what I am doing wrong?

Michael - sqlbot over 8 yearsGood catch. Problem #2, after that is fixed, is that S3 buckets don't expect "form data" on a
PUT
request. They expect the request body to contain the raw octets of the object being uploaded. -
pmcoltrane over 8 yearsI've mostly been working with the Javascript API rather than directly sending REST requests. Not sure what your form data looks like, but the example at docs.aws.amazon.com/AmazonS3/latest/API/sigv4-post-example.html might move you in the right direction?
