S3 Upload with Transfer Acceleration

See more Amazon S3 Examples

Demonstrates how to upload from a pre-signed URL with transfer acceleration. Ruby

require 'chilkat'

success = false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()

http.put_AwsAccessKey("AWS_ACCESS_KEY")
http.put_AwsSecretKey("AWS_SECRET_KEY")

# Make sure to set your AWS region correctly
http.put_AwsRegion("us-east-1")
bucketName = "chilkat200"
objectName = "starfish/starfish.jpg"
awsService = "s3"
httpVerb = "PUT"

# To use S3 acceleration, we simply set the AwsEndpoint to "s3-accelerate.amazonaws.com".
# Note: You must enable transfer acceleration on your bucket.  Acceleration incurs a higher cost.
http.put_AwsEndpoint("s3-accelerate.amazonaws.com")

# The signed URL will be valid for this number of seconds:
numSecondsValid = 86400

# Choose between a URL beginning with "http://" or "https://"...
bUseHttps = true

# Generate the pre-signed URL that will use s3-accelerate.amazonaws.com
preSignedUrl = http.s3_GenPresignedUrl(httpVerb,bUseHttps,bucketName,objectName,numSecondsValid,awsService)
if (http.get_LastMethodSuccess() == false)
    print http.lastErrorText() + "\n";
    exit
end

# The following URL can be copy-and-pasted into a browser..
print "Presigned URL for Upload: " + preSignedUrl + "\n";

# Here's an example of a pre-signed URL
# 
# http://chilkat200.s3-accelerate.amazonaws.com/starfish/starfish.jpg?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAIBJLOVZVXAU2AFUA%2F20200623%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20200623T234049Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=xxxxxeaea071178d772856c0a4e4c0114a8d9992f0d0812955e490d0exxxxxxx

# Upload a local file using the pre-signed URL.
