# we use two libraries for this example
require ‘hmac-sha1′
require ’soap/rpc/driver’

# set up some default variables
url = “draftwizard.com”
responsegroup = “Rank”
temp = Time.now.utc

# get the time into the format for creating our signature
t1 = temp.strftime(”%Y-%m-%dT%H:%M:%SZ”)

newtime = t1.to_s

encval = “AlexaWebInfoServiceUrlInfo” + t1.to_s

# now actually create our signature (based on rules supplied in AWS documentation)
myhmac = HMAC::SHA1.digest(”YOUR AMAZON/ALEXA KEY TO GENERATE SIGNATURE”, encval)

# it needs to be binary, and for some reason the packing was addining one extra character; hence the chomp
myhmac = myhmac.to_a.pack(”m”).chomp

# now we can set up our driver
driver = SOAP::RPC:: Driver.new(”awis.amazonaws.com/onca/soap?Service=AlexaWebInfoService”,”webservices.amazon.com/AWSAlexa/2005-07-11″)

driver.add_rpc_method_with_soapaction_as(”test”, “UrlInfo”, “UrlInfo”, “AWSAccessKeyId”, “Signature”, “Timestamp”, “Url”, “ResponseGroup”)

# and finally we can make ou real request for the data
result = driver.test(”YOUR ALEXA KEY”, myhmac, newtime, url, responsegroup)

# and display the results.
puts result[1]["Alexa"]["TrafficData"]["Rank"]

The driver = line above has a space after the RCP colons (and before the word Driver)…that’s because the colon D on this msg. board renders as a smiley…so I added the space so the image wouldn’t render…but in your actual code, you can not have the space there. Just a head’s up.

I’m trying to use Ruby/Amazon to add some information to a product database and run into lots of either “is not a module” or “uninitialized constant Search” type errors.

Things run ok from the command line so I’m trying to figure out if there is a trick with 1.0?
Thank you,
