Has anyone successfully done this?
My idea is to post to a servlet and it will respond with Query String Request Authentication url after the servlet has authenticated the user. The user will then use this url to upload a picture file.
Was wondering if this is even possible.
The thing I don't get is how do you transfer the picture from your computer or device to the s3.
This is the StringToSign:
PUT\n (content here?)\n image/jpeg\n 1175139620\n /johnsmith/photos/puppy.jpg
How do I inser the content into the string to sign? Do i base64 it first then md-5 it?
