[Voiceglue] VoiceGlue urlencoding '?' as %3F results in HTTP 404 response for Vxml page fetch

[James Green]

I think the ? needs urlencoding at the extensions.conf level.
 
Ours looks like this:
exten =>
s,n,AGI(agi://localhost/url=http%3A%2F%2Fvoice.server%2Fvxml%2FCallGener
ator.vxml.php/${message_id})

The string after url= then gets decoded by the AGI module and fired off.
That's my reading of things anyway.

Subject: [Voiceglue] VoiceGlue urlencoding '?' as %3F results in HTTP
404 response for Vxml page fetch



I have a problem getting voiceglue to fetch a vxml page from a web app
(deployed on a remote server under JBOSS/Tomcat).

 

I have voiceglue 0.11 on RHEL5.

 

It seems no matter how I provide the vxml url to voiceglue it always
urlencodes the parameter code '?' in the URL which results in a HTTP 404
response.

 

e.g. in asterisk extensions.conf :

 

exten =>
dialog,n,Agi(agi://localhost/url=${vxmlurlContext}?${vxmlurlParam})

 

The asterisk log shows a correctly formatted url with parameter part
encoded:

 

[Feb 11 17:13:35] VERBOSE[28945] logger.c:     -- Executing
[dialog at from-sip:6]
[1;36;40mAGI[0;37;40m("[1;35;40mSIP/2002-00000015[0;37;40m",
"[1;35;40magi://localhost/url=http://129.223.122.177:7001/NotificationPl
ayer/voiceapp?notificationInfoURL=http%3A%2F%2F129.223.122.177%3A7001%2F
ns%2Fnotificationinfo%3FSSID%3D2293Flow2296[0;37;40m") in new stack

[Feb 11 17:13:38] VERBOSE[28945] logger.c:     -- <SIP/2002-00000015>AGI
Script
agi://localhost/url=http://129.223.122.177:7001/NotificationPlayer/voice
app?notificationInfoURL=http%3A%2F%2F129.223.122.177%3A7001%2Fns%2Fnotif
icationinfo%3FSSID%3D2293Flow2296 completed, returning 0

 

Yet a tcpdump on the target server shows the url in the http request to
be fully urlencoded except for the '/''s which actually decoded in the
parameter portion even though they were provided encoded:

 

GET
/NotificationPlayer/voiceapp%3FnotificationInfoURL%3Dhttp%3A//129.223.12
2.177%3A7001/ns/notificationinfo?SSID=2293Flow2296

 

Can anyone point me at a solution or even the component in voiceglue
that does the encodeing and vxml page fetch?

 

Thanks

Steve
