I haven't developed the module, will have to look at the code, but I would expect to work for the array object, given it relies on libjansson external library.
Maybe you can try with:$avp(result1)="{\"a\":[{\"origin\":\"125.16.231.74\",\"Dest\":\"725.76.731.77\"}]}";

 just to see if it works and there is no problem parsing that array, but the problem is having an array as root object.

 Cheers,
 Daniel

I understand that with "[ ]" , its the right JSON object. But api doesnt give the parsed result.
 
Thanks,
Vivek.

Hi All,
 
Am using JANSSON module to parse the JSON object I receive.
 
I tried using JSON module of kamailio. Since its giving error in loading the module due to  error"libjson-c.so.3: cannot open shared object file: No such file or directory", I went ahead to use JANSSON module.
 
JANSSON module is parsing the single JSON object perfectly. But not parsing the multiple JSON objects.
 
JSON object am trying to parse:
$avp(result1)= "[{"origin":"125.16.231.74","Dest":"725.76.731.77"},{"origin":"225.26.231.24","Dest":"225.26.231.27"}]"
 
JANSSON API used: jansson_get("origin", "$avp(result1)", "$var(origin)");
 
Any suggestions will be really helpful.are there any error messages?

 Cheers,
 Daniel
