Create Asset S3 Usage

[Kevin]

I'm fairly new to not only using Sorenson API but also Amazon S3
usage.

I am able to access the Create Asset API without providing file
information and see that I get back S3 information. However I'm not
entirely sure how to use this information to upload the file. I've
signed up for a free dev S3 account but can't seem to figure it out as
I keep getting errors and have no clue if I'm doing it correctly or
not.

Does anyone have any guidance on how to do so?

By the way, I am using ColdFusion as the application server

Kevin,

After you get the S3 info back from Create Asset you need to use HTTP POST to upload your source file. Here's a sample CURL command:

curl -i -F AWSAccessKeyId=<aws_access_key_id> -F acl=public-read -F key=<s3_key> -F policy=<s3_policy> -F signature=<s3_signature> -F filename=<filename> -F file=@/local/path/to/file.mp4 http://<s3_bucket>.s3.amazonaws.com

And here's a sample POST with header info etc.:

POST /<s3_key> HTTP/1.1

Host: <s3_bucket>.s3.amazonaws.com

User-Agent: http-client-lib

x-amz-acl: public-read
