从浏览器直接上传到S3（亚马逊）和https麻烦

Question

I have created a page from where users can upload their files. This code snippet send those files to my Amazon S3 bucket.

<form action="https://BUCKET.s3-eu-west-1.amazonaws.com/" method="post" enctype="multipart/form-data">
  <input type="hidden" name="awsAccessKey" value="ACCESS_KEY">
  <input type="hidden" name="awsSecretKey" value="SECRET_KEY"> 
  <input type="hidden" name="acl" value="private"> 
  <input type="hidden" name="policy" value="POLICY">
  <input type="hidden" name="signature" value="SIGNATURE">
  <input type="hidden" name="Content-Type" value="">
  <!-- Include any additional input fields here -->

  File to upload to S3: 
  <input name="file" type="file"> 
  <br> 
  <input type="submit" value="Upload File to S3"> 
</form> 

Everything works fine, but I am facing https problems. Main browsers don't trust s3-eu-west-1.amazonaws.com and show security message about untrusted connection.

I changed my the HTTPS connection to HTTP so that my customers don't face any problem. Does someone have any ideas on how to resolve this issue?

Chances are your bucket name has a dot in it. Amazon's S3 wildcard certificates are good for only one level of subdomains, so bucket.s3-eu-west-1.amazonaws.com is fine but bucket.bucket.s3-eu-west-1.amazonaws.com is not. Use this instead:

https://s3-eu-west-1.amazonaws.com/BUCKET/
