SignatureDoesNotMatch - Amazon S3 API

Question

I am using a PHP class for Amazon S3 and CloudFront - Link. But when I try to upload a file into a bucket, I get this error:

[SignatureDoesNotMatch] The request signature we calculated does not match the signature you provided. Check your key and signing method.

How to fix it?

Thanks.

Answer 1

I had this error with putObject() when specifying a Key starting with slash character (/) - after removing the slash it worked fine.
