CFHTTP issues

(warning: cold fusion technospeak ahead)

So I’m developing an application that makes use of the eBay API. In this application, there is a need to send well-formatted xml to eBay. In addition, all requests must include certain HTTP Header information, so that eBay knows just who the hell is talking to them. Why is this a problem? well, in CFMX, you can send a type XML parameter via CFHTTP. The problem is that if you have a type XML parameter, you’re not allowed to send anything else (I’ve no idea why). So, why don’t I just send the XML as a formfield or something? Because I need to send the XML as content, not as a header. If I try and send it as type CGI, or URL, or FormField, or Cookie, I get no response back. Interestingly, if I send a .xml file (using type=”file”), I get a whole new error (bad developerID in the session certificate — but I’ve confirmed that it is indeed, valid, so I’ve no idea why I get that error). So it looks like I can’t use CFHTTP, which is really, really odd. So I’ve resorted to calling the Microsoft ServerHTTPXML COM Object, and using that. Which works just peachy, thanks.

Here’s the working code (where #string# is a properly formed XML document) (by the way, we’re not here to critique my naming conventions — these are temporary for a prototype):

<CFOBJECT action="Create" name="objSrvHTTP" class="MSXML2.ServerXMLHTTP">
<CFSETdummy=objSrvHTTP.open("POST","#request.targetURL#",false)>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-COMPATIBILITY-LEVEL","#request.CompatibilityLevel#")>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-SESSION-CERTIFICATE","#request.DevID#;#request.AppID#;#request.CertID#")>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-DEV-NAME","#request.DevID#")>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-APP-NAME","#request.AppID#")>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-CERT-NAME","#request.CertID#")>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-CALL-NAME","#attributes.CallName#")>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-SITEID","#request.siteID#")>
<CFSET dummy=objSrvHTTP.setRequestHeader("X-EBAY-API-DETAIL-LEVEL","#request.DetailLevel#")>
<CFSET dummy=objSrvHTTP.send("#ToString(string)#")>
<CFSET results=XMLParse(objSrvHTTP.responsetext)>

And here’s the non-working CFHTTP code:

<CFHTTP method="POST" url="#request.targetURL#" resolveurl="No" timeout="10" throwonerror="Yes">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-COMPATIBILITY-LEVEL" value="#request.CompatibilityLevel#">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-SESSION-CERTIFICATE" value="#request.DevID#;#request.AppID#;#request.CertID#">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-DEV-NAME" value="#request.DevID#">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-APP-NAME" value="#request.AppID#">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-CERT-NAME" value="#request.CertID#">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-CALL-NAME" value="#attributes.CallName#">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-SITEID" value="#request.siteID#">
<CFHTTPParam type="#variables.headerType#" name="X-EBAY-API-DETAIL-LEVEL" value="#request.DetailLevel#">
<CFHTTPParam type="FILE" name="xml" file="#request.filepath#test.xml">
</CFHTTP>
<CFSET results=XMLParse(cfhttp.filecontent)>

My question to the world is then: Is there a way to send content via CFHTTP? If you’re familiar with the eBay API, is there a reason why when I send an XML file via CFHTTP, it gives me nice error code in response, and when I send it in any other format, I get nothing back at all (and I know the DevID is right, because the COM object call works, using the same one).

  1. I’m having the same problem with CFHTTP. It seems to screw up XML pretty nicely. The MSXML object seems to be the only way I can get it to work.
