[Zoo-discuss] BufferPy problem

Sun Jan 13 23:16:13 PST 2013

Hi Farkas,
personally I think that it is a good point to get the curl request working as it means that your ZOO-Kernel is correctly working.

I would like to make sure that you get also the XML response but as you said you get a correct response I guess it is the case.

You said you removed the carriage returns, did you try without the carriage return with curl to make sure there is no issue on that side ?
I think that this should confirm or not that there is no problem on the ZOO-Kernel side but only on the way we are requesting it.

Note that you should be able to use the $.ajax function without any issue, you should use it in the following way:

$.ajax({
	type: "POST",
	url: "http://localhost/cgi-bin/zoo_loader.cgi",
	contenteType: "text/xml",
	data: data,
	complete: function(xml,status){
		alert(xml.reponseText);
	}
});

This should not imply that you get OPTION request from apache error log. Please make sure you use well this Ajax request and not another one probably present in your application.

I'm pretty sure this will work.

Hope to hear back from you,
Best regards,

I guess it would be helpful for testing your ZOO-Kernel version and make sure it can handle properly the POST requests to run curl from command line.
