Consuming org.glassfish.grizzly.utils.BufferInputStream@ Mule

Question

I've 2 json feeds in payload (using Gather), i planned on using a groovy script to make it into a single json (I expected something like:

{key:value}{key:value})
<scripting:transformer doc:name="Groovy">
        <scripting:script engine="Groovy"><![CDATA[return '{"data":['+payload.toString().replace("}{","},{"+']}']]></scripting:script>    
    </scripting:transformer>

(expected output: {"data":[{key:value},{key:value}]}

But i get:

{"data":[[org.glassfish.grizzly.utils.BufferInputStream@102e37e, org.glassfish.grizzly.utils.BufferInputStream@a569d1]]}

W/O groovy script:

[org.glassfish.grizzly.utils.BufferInputStream@102e37e, org.glassfish.grizzly.utils.BufferInputStream@a569d1]

an array of inputstream

I tried using byte array to string, and object to string but it doesnt work, I dont figure out how can i solve this

Answer 1

Replace:

payload.toString().replace("}{","},{")

with:

payload.collect { it.text }.join(',')

Explanation: .text deserializes an input stream to a string, so payload.collect { it.text } will yield a collection of strings. Then join(',') takes care of concatenating these strings, separating them with ,
