Hi all,



Is it possible to set the value of a channel variable to a JSON formatted string?


I need to do something like this:


<action application="set" data="MY_VAR=[\"Ford\", \"Chevy\"]"/>

The problem seems to be that FS is not accepting the escape sequence and MY_VAR gets set to [\


How do I go about escaping double quotes in the dialplan?

you create FreeSwitch mod using asr_set_json_text_params as example.

Thanks for the response, but actually all I needed to do was URL encode the JSON.


So the working version of
       <action application="set" data="MY_VAR=[\"Ford\", \"Chevy\"]"/>
is


<action application="set" data="MY_VAR= %5B%5C%22Ford%5C%22%2C%20%5C%22Chevy%5C%22%5D"/>

You can do that with standard xml CDATA syntax, find examples in the source tree https://github.com/signalwire/freeswitch/blob/master/conf/sbc/dialplan/default.xml

Yes, CDATA should work and also you can use &quot; for double quotes and &amp for single quotes.

I thought &amp was for ampersand, is that not correct?

Very much correct.  Single quote is &apos;
