coldfusion struct in function argument - facebook

Question

I'm trying to do server side facebook connect, but the sdk (get it here) provided gives the following error:
Invalid CFML construct found on line 523 at column 78.
ColdFusion was looking at the following text:
{
And it doesn't explain why it's throwing this error. I'm not good at cfscript, so I don't know whether the sdk uses the correct syntax, but it throws the error on this function, at the braces of the struct in the function arguments:
private String function getUrl(String path = "", Struct parameters = {})
{
var key = "";
var resultUrl = "https://www.facebook.com/" & arguments.path;
if (structCount(arguments.parameters)) {
resultUrl = resultUrl & "?" & serializeQueryString(arguments.parameters);
}
return resultUrl;
}
I had thought that using an sdk would be a no brainer, but apparently I'm missing something.
What am I doing wrong?
Part 2:
The code now comes to a halt at:
for (var propertyName in arguments.properties) {
httpService.addParam(type="formField", name=propertyName, value=arguments.properties[propertyName]);
}
Are you not allowed to use a for loop in cfscript?

Answer 1

Try structNew() or "#structNew()#" instead of {}

Answer 2

This should work for connecting to Facebook and getting an access token:
<cfset appID = ""/>
<cfset secret_key = ""/>
<cfset app_url = ""/>
<cfparam name="URL.Code" default="0">
<cfparam name="URL.state" default="0">
<cfparam name="SESSION.Redirect" default="0">
<cfset code_ = URL.Code>
<cfif code_ EQ "" OR code_ EQ 0>
<cfset SESSION.State = Hash(CreateUUID(),"MD5")>
<cfset dialog_url = "http://www.facebook.com/dialog/oauth?client_id=" & appID & "&redirect_uri=" & app_url & "&scope=email,user_photos,publish_stream" & "&state=" & SESSION.State>
<cflocation url="#dialog_url#" addtoken="no">
</cfif>
<cfif SESSION.State EQ URL.State>
<cfset token_url = "https://graph.facebook.com/oauth/access_token?client_id=" & appID & "&redirect_uri=" & app_url & "&client_secret=" & secret_key & "&code=" & code_>
<cfhttp url="#token_url#" result="AccessToken" method="GET">
<cfelse>
<p>The state does not match. You may be a victim of CSRF.</p>
</cfif>
