How do I post to Facebook Graph API with Coldfusion?

The following works fine up until my cfhttp post.

I want to post with cfhttp to a user's wall/timeline.

<!--- This is the page that you call and also use as the redirect_uri... facebook returns code and state in the URL --->
<cfparam name="URL.code" default="" type="string">
<cfparam name="URL.state" default="" type="string">
<cfif #URL.code# EQ "">
    <cfparam name="URL.error_reason" default="" type="string">
    <cfparam name="URL.error" default="" type="string">
    <cfparam name="URL.error_description" default="" type="string">
    <cfmail charset="utf-8" type="html" server="mail.mysite.com" from="messages@mysite.com" to="messages@mysite.com" subject="Facebook Authentication Denial">
    #SESSION.my_profile_id#: #SESSION.my_profile_username#
    #URL.error_reason#<br/>
    #URL.error#<br/>
    #URL.error_description#<br/>
    </cfmail>
    <cfabort>
<cfelse>
    <cfhttp 
    method="get"
    url="https://graph.facebook.com/oauth/access_token?client_id=myappid&redirect_uri=http://www.mysite.com/d..."
    result="my_fb_user_token"/>
    <cfif #my_fb_user_token.filecontent# CONTAINS "access_token=">
        <cfset new_token = ReplaceNoCase(#my_fb_user_token.filecontent#,"&expires","|","all")>
        <cfset new_token = REReplaceNoCase(#new_token#,"\|.*$","")>
        <cfquery name="fb_confusion" datasource="#dsn#" maxrows="1">
        SELECT facebook_id
        FROM my_profile
        WHERE my_profile_id = '#SESSION.my_profile_id#'
        </cfquery>
        <cfoutput>#new_token#</cfoutput>
        <hr/>
        <cfhttp 
        method="get"
        url="https://graph.facebook.com/me?#new_token#"
        result="my_fb_user"/>
        <cfoutput>https://graph.facebook.com/#fb_confusion.facebook_id#/feed?#new_token#</cfoutput>
        <hr/>
        <cfoutput>
        <cfhttp url="https://graph.facebook.com/me/mysite:add?group=http://www.mysite.com/dbf/test_group.cfm&#new_token#"
        result="fb_publish" 
        method="post" 
        multipart="yes">
            <cfhttpparam name="appID" value="myappid" encoded="no" type="url">
            <cfhttpparam name="access_token" value="#my_fb_user_token.filecontent#" encoded="no" type="url">
            <cfhttpparam name="message" value="Test" encoded="no" type="url">
            <cfhttpparam name="link" value="http://www.mysite.com" encoded="no" type="url">
            <cfhttpparam name="name" value="Test" encoded="no" type="url">
            <cfhttpparam name="caption" value="Testing fb api" encoded="no" type="url">
            <cfhttpparam name="description" value="Testing to see if this posts" encoded="no" type="url">
        </cfhttp>
        </cfoutput>
        <cfdump var="#fb_publish.filecontent#">
    </cfif>
</cfif>

The message returned from the fb_publish dump is:

{"error":{"message":"Invalid OAuth access token.","type":"OAuthException","code":190}}

Ok thank you Ray C for helping out with this.  Couple things... first, the URL being called by the http post needs to synch up with what facebook requires.

https://graph.facebook.com/me/[YOUR_APP_NAMESPACE]:cook?recipe=OBJECT_URL&access_token=ACCESS_TOKEN

Next, all the type="url" in the cfhttp form params needed to be changed to formfield.

Now it works.

Thanks!
