[Zoo-discuss] POST not implemented

Sat Aug 2 08:33:02 PDT 2014

Dear Pablo,
I would like to know what is the ZOO-Kernel version you are currently using ?
Indeed it sounds strange that switching from GET to POST change so much thing. In other case, this have to be review and fixed asap.
So, I would like to invite you to build the ZOO-Kernel from the SVN trunk source tree and try the same requests against this version and report any issue if you have still one.

I hope to hear back from you,

Best regards,

> From my point of view, there is an issue in the request you provided, you defined the mimeType attribute of your ComplexeData node to « text/xml » which is valid, but then, rather than providing a XML node in the request, you provided a CDATA node which should be used for ComplexData with the mimeType defined to application/json for instance.
> 
> In the case of mimeType defined to text/xml, the ZOO-Kernel is searching for a XML node which will be used as a root of a new document which will then be used to POST the request to the targeted server.

> So your request should work by removing both: «  <![CDATA[ » and « ]]> » from its content.

> If anybody think that it is wrong to handle the text/xml content the way ZOO-Project is doing, then please speak up and let me know.
> I wonder, cause it is not the first time that somebody send such kind of requests. The issue Steve faced with his request was really similar to this one.
