"400 Your default mime type is not implemented" error

[Jose Gosende]

I just downloaded Taffy earlier today and I'm running into what I'm sure is a simple error, but I can't figure out what's wrong:

"400 Your default mime type is not implemented"

Running ACF 9,0,1,274733 and latest version of Taffy.

File:

/resources/contactCollection.cfc

<cfcomponent extends="taffy.core.resource" taffy:uri="/contacts" taffy:mime="application/json">

<cffunction name="get">

<cfset var local = {} />

<cfquery name="local.qGetcontacts" datasource="#application.dsn#">

SELECT TOP 5 *

FROM contacts

</cfquery>

<cfreturn representationOf( local.qGetcontacts ) />

</cffunction>

</cfcomponent>

Client code:

<cfhttp method="get" url="http://api.myTestBox.net/API/index.cfm/contacts" result="getcontactsRet">

<cfhttpparam type="header" name="content-type" value="application/json"/>

</cfhttp>

<p><cfdump var="#getcontactsRet#"></p>

Response:

struct
Charset	[empty string]
ErrorDetail	[empty string]
Filecontent	Bad Request
Header	HTTP/1.1 400 Your default mime type is not implemented Content-Type: text/html Date: Mon, 03 Jun 2013 17:21:35 GMT Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET

Statuscode	400 Your default mime type is not implemented
Text	YES

If I specify http://api.myTestBox.net/API/index.cfm/contacts.json, it works.

Application.cfc

<cfcomponent extends="taffy.core.api">

<cfscript>

this.name = hash(getCurrentTemplatePath());

variables.framework = {};

variables.framework.debugKey = "debug";

variables.framework.reloadKey = "reload";

variables.framework.reloadPassword = "true";

variables.framework.representationClass = "taffy.core.nativeJsonRepresentation";

variables.framework.returnExceptionsAsJson = true;

variables.framework.reloadOnEveryRequest = true;

// do your onApplicationStart stuff here

function applicationStartEvent(){

application.dsn = "testDSN";

}

// do your onRequestStart stuff here

function requestStartEvent(){}

// this function is called after the request has been parsed and all request details are known

function onTaffyRequest(verb, cfc, requestArguments, mimeExt){

// this would be a good place for you to check API key validity and other non-resource-specific validation

return true;

}

</cfscript>

</cfcomponent>

TIA,

Jose

Hi Jose,

First, the metadata that you're adding to your resource ("taffy:mime") is not doing anything (Taffy doesn't look for it here) -- not sure where you got that idea from.

Second, I'm glad you figured out the ".json" workaround. :)

Third, just to be sure, you say that you're using the latest version of Taffy. Does that mean you downloaded using the zip download link on the github homepage / cloned the master branch? Or did you download the latest tagged release?

I've been meaning to add a version number comment to api.cfc / the taffy application scope variables, but haven't gotten around to it yet.

This bug has been around for a while but seems to be a whack-a-mole situation. Every time I think I've got it fixed it seems to rear its ugly head elsewhere. I'll see what I can do.

Hi Adam,

I downloaded the latest tagged release from http://atuttle.github.io/Taffy/  (atuttle-Taffy-v1.3.2-6-g22bdda0.zip)

Just for kickcs, I decided to restart the instance of JRun hosting this and all of sudden it works.

FYI - I kept the "taffy:mime" code and didn't get an error (I've removed it since).

As I'm just getting started with Taffy I'm sure I'll have more questions, so don't go too far :)

Thanks,

Jose

Yeah, I wouldn't expect an error for the "taffy:mime" bit, it's just not going to do anything. You could set its value to "text/goat" and it wouldn't hurt anything...
