How can I create a JSON payload with text containing XML in it? - json

Question

I try to create an automatic JIRA problem reporting (in some FAULT sequences.
I make a JSON payload for JIRA APIs what works just fine for text.
I would like to however report to JIRA a SOAP request and response whereby I could investigate on the issue.
my question is how can I create a JSON payload with text containing XML in it?
I get this exception in WSO2 ESB
[2016-09-18 21:46:31,774] ERROR - NativeWorkerPool Uncaught exception
java.lang.Error: Error: could not match input

at org.apache.synapse.commons.staxon.core.json.stream.impl.JsonScanner.yylex(JsonScanner.java:941)
payload which I want to generate
<payloadFactory description="" media-type="json">
<format>
{
"fields": {
"project":
{
"key": "$1"
},
"summary": "$2",
"description": "$3",
"issuetype": { "name": "$4" }
}
}
</format>
<args>
<arg evaluator="xml" expression="$func:projectKey"/>
<arg evaluator="xml" expression="$func:summary"/>
<arg evaluator="xml" expression="$func:description"/>
<arg evaluator="xml" expression="$func:issueType"/>
</args>
</payloadFactory>
and I want to send some text containing XML into the parameter $func:description. When I sent only poor XML into the $func:description, the payload Factory transferred into into JSON what is not needed in this case, the the XML is supposed to be a text - the message
for the completeness to get the XML message I used
<property expression="$body" name="request"
scope="default" type="STRING"/>
call the end-point
<property expression="$body" name="response"
scope="default" type="STRING"/>
and I need to know bind "request" + "response" into $func:description

Answer 1

If the XML is well-formed you can simply set messageType property to application/json and do the conversion automatically. Refer this for more details.
Or else you can use the payload Factory mediator or Enrich mediator to custom build your Json.

Answer 2

create the payload with the XML structure you like.
use JS script mediator to modify one node as CDATA.
change the content type.
My proxy config, please do the change you need for your requirement:
