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

# When usig the REST class to access an S3 bucket that has been created in a particular region,
# there are three important things to remember:
# 
# 1) Connect to the domain that includes the region.  For example, instead of connecting to
#    "s3.amazonaws.com", connect to "s3.eu-central-1.amazonaws.com" if your bucket is in the EU Frankfurt region.
#    See http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region   for a list of S3 region domains (endpoints)
# 
# 2) Set the AuthAws.Region property equal to the region, such as "eu-central-1".
# 
# 3) Include the region in request's Host header.
# 

# This example will upload to a bucket in the eu-central-1 region.
# 
rest = chilkat.CkRest()

# Connect to the Amazon AWS REST server.
bTls = True
port = 443
bAutoReconnect = True
success = rest.Connect("s3.eu-central-1.amazonaws.com",port,bTls,bAutoReconnect)

# Provide AWS credentials for the REST call.
authAws = chilkat.CkAuthAws()
authAws.put_AccessKey("AWS_ACCESS_KEY")
authAws.put_SecretKey("AWS_SECRET_KEY")
authAws.put_ServiceName("s3")
authAws.put_Region("eu-central-1")
success = rest.SetAuthAws(authAws)

# Set the bucket name via the HOST header.
# In this case, the bucket name is "chilkateufrankfurt" (which was created in the eu-central-1 region)
rest.put_Host("chilkateufrankfurt.s3.eu-central-1.amazonaws.com")

fileData = chilkat.CkBinData()
success = fileData.LoadFile("qa_data/jpg/starfish.jpg")

# Upload the file to Amazon S3.
responseBody = chilkat.CkStringBuilder()
success = rest.FullRequestBd("PUT","/starfish.jpg",fileData,responseBody)
if (success != True):
    print(rest.lastErrorText())
    sys.exit()

# Did we get a 200 response indicating success?
statusCode = rest.get_ResponseStatusCode()
if (statusCode != 200):
    print("Error response: " + responseBody.getAsString())
    print("Status code: " + str(statusCode) + ", Status text: " + rest.responseStatusText())
    sys.exit()

print("File successfully uploaded.")
