[Freeswitch-users] Strange xml_curl behavior. Can't see more than 7 variables on POST

[Muhammad Naseer Bhatti]

Since I am using nginx to serve the requests, it turns out to be ngx.req.get_post_args() takes a limited number of arguments in the body by default. 100 to be exact by default. If I change the value to a larger number, I am able to see all the variables in POST.

ngx.req.read_body()
local XML_REQUEST = ngx.req.get_post_args(1000)

for k, v in pairs (XML_REQUEST) do
  if (k:match('variable')) then
    log.debug ('['..k .. '] : [' .. v..']')
  end
end

Solved..

No, it’s the same with or without cacheable set to 0 or anything else. Here is the list of all variables I can see, https://pastebin.freeswitch.org/23740

Does it behave differently without the cacheable tag?

Forgot to mention that I am also pulling up dialplan configuration from xml_curl. I am seeing all the variables when request for a dialplan.

I am using xml_curl to generate all config dynamically and this is getting very strange, my directory looks like this, 

<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<document type='freeswitch/xml'>
 <section name='directory'>
  <domain name='10.211.55.26'>
  <user id='9401404' cacheable='2000'>
  <params>
  <param name='a1-hash' value='3c66e98d4b174b42d3e17669b59165c9'/>
  <param name='max-registrations-per-extension' value='1'/>
  <param name='allow-empty-password' value='false'/>
  <param name='sip-force-expires' value='180'/>
  </params>
  <variables>
  <variable name='customer_id' value='98765'/>
  <variable name='effective_caller_id_name' value='Mr Bhatti'/>
  <variable name='effective_caller_id_number' value='9401404'/>
  <variable name='debug_call' value='0'/>
  <variable name='debug_sql' value='0'/>
  <variable name='user_context' value='vbilling'/>
  <variable name='hangup_after_bridge' value='true'/>
  <variable name='xbypass' value='google'/>
  <variable name='account_type_02' value='pre'/>
  <variable name='account_type_03' value='pre'/>
  <variable name='account_type' value='pre'/>
  </variables>
  </user>
  </domain>
 </section>
</document>

The directory is working fine and user is able to login. I have a bunch of variables defined here. When I look at the POST on the web server, I am only able to see first 7 variable no matter what their names are. If I change order for example account_typewhich is last variable, and make it on top, it shows there in the XML_REQUEST but then hangup_after_bridgegoes away. I see only first 7. Are there any limitation on what channel variables can be POSTed to the web server or am I missing something here.
