Get response body when using <data> and HTTP response != 2xx

Hi,
My app server uses HTTP response codes 5xx to indicate 'normal' application errors (e.g., missing request data, failed business rule, etc). In these cases, the HTTP response contains error data that I'd like to use in the VXML script.
Can I get access to the HTTP document response data (JSON data) when the HTTP response code is 5xx?
Thanks...Scot

Hi Scot,
You can capture HTTP error codes by using the <catch> tag. Here's an example snippet of VoiceXML:
Code: Select all
<?xml version="1.0"?>
<vxml version="2.0">
<form>
<block>
<prompt>
gonna go to a badfetch page
</prompt>
<goto next="http://pagethatreturns5xx.com"/>
</block>
<catch event="error.badfetch">
<prompt>
caught a badfetch error <value expr="_event"/>
</prompt>
</catch>
</form>
</vxml>
Your script can parse the contents "_event" variable that's set by the <catch> tag and branch accordingly.

Thanks. Can I get access to the response body as well? When my app responds with HTTP code 5xx there is additional error info within a JSON string contained in the response body.
Thanks...Scott

Hi Scott,
There are no facilities that allow access to the response body. You can, however, differentiate between different error codes by specifying more granular catch event strings. So, for instance, if you have <catch> blocks for "error.badfetch" and "error.badfetch.503", if an HTTP 503 were to be thrown, the latter block would be the one executed as the matching string is longer.

Ok - thanks. Are there plans to add this feature? If not, how do I submit an enhancement request?
