Clark,
I do remember battling this one for a little while one day -- granted I am
using Railo but it should work no problem in Adobe CF as well. Here is the
code from my CFC which pulls data from Amazon's Alexa:
You will also notice I am using a hash function custom tag which Amazon wants
as well. You would want to put your key and secret key in below...
<cfset var digest = "">
<cfset var signature = "">
<cfset var amazon = "">
<cfset var actionName = "UrlInfo">
<cfset var key="xxxxxxxxxxxxxx">
<cfset var secretkey="xxxxxxxxxxxxx">
<cfset var dateTimeString = GetHTTPTimeString(Now())>
<cfset setTimezone("Etc/GMT+0")>
<cfset var Timestamp = DateFormat(dateTimeString, "yyyy-mm-dd") & "T" &
lsTimeFormat(dateTimeString, "HH:mm:ss") & ".000Z">
<cf_hmac data="#actionName##Timestamp#" key="#secretkey#" hash_function="sha1" >
<cfset signature = ToBase64(Binarydecode("#digest#","hex"))>
<cfset var AmazonURL =
"http://awis.amazonaws.com/?AWSAccessKeyId=#key#&Timestamp=#URLEncodedFormat(timestamp)#&Signature=#signature#&Version=2005-07-11&Action=#actionName#&ResponseGroup=RankByCity,TrafficData,OwnedDomains,LinksInCount&Url=#arguments.siteURL#">
<cfhttp method="get" url="#AmazonURL#" result="amazon">
<cfhttpparam type="Header" name="TE" value="deflate;q=0">
<cfhttpparam type="header" name="Accept-Encoding" value="*" />
<cfhttpparam type="header" name="Accept"
value="text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5">
<cfhttpparam type="header" name="Accept-Language"
value="en-us,en;q=0.5">
</cfhttp>
Regards,
Jeremy
