[Dev] Write File with VFS on Rest APIs

[Júnior]

Hi,

I am trying to create a REST API on EI 6.1.1 that receives a JSON, and one
of the JSON fields contains the name of the file that I would like to
create and its contents in Base64 encode, the API code is below:

<?xml version="1.0" encoding="UTF-8"?>
<api xmlns="http://ws.apache.org/ns/synapse";
     name="ImageAPI"
     context="/image">
   <resource methods="POST" uri-template="/add">
      <inSequence>
         <property name="OUT_ONLY" value="true"/>
         <property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>
         <header name="To" scope="default" action="remove"/>
         <log level="full"/>
         <property name="fileName"
                   expression="json-eval($.fileName)"
                   scope="default"
                   type="STRING"/>
         <property name="fileContent"
                   expression="json-eval($.fileContent)"
                   scope="default"
                   type="STRING"/>
         <payloadFactory media-type="xml">
            <format>
               <ns:binary xmlns:ns="http://ws.apache.org/commons/ns/payload
">$1</ns:binary>
            </format>
            <args>
               <arg evaluator="xml" expression="$ctx:fileContent"/>
            </args>
         </payloadFactory>
         <script language="js">var binaryNode =
 mc.getEnvelope().getBody().getFirstElement().getFirstOMChild();
 binaryNode.setBinary(true);</script>
         <property name="transport.vfs.ReplyFileName"
                 scope="transport" type="STRING"

 expression="fn:concat(fn:substring-after(get-property('MessageID'),
'urn:uuid:'), '.png')"/>
         <log level="custom">
            <property name="fileName"
expression="get-property('fileName')"/>
            <property name="REST_URL_POSTFIX"
expression="get-property('REST_URL_POSTFIX')"/>
            <property name="TRANSPORT_HEADERS"

expression="get-property('axis2','TRANSPORT_HEADERS')"/>
         </log>
<property name="FORCE_SC_ACCEPTED" scope="axis2" type="STRING"
value="true"/>
<property name="REST_URL_POSTFIX" scope="axis2" type="STRING" value=""/>
<property name="OUT_ONLY" scope="default" type="STRING" value="true"/>
         <send>
            <endpoint>
               <address
uri="vfs:file:///E:/test?transport.vfs.Append=true"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence/>
      <faultSequence/>
   </resource>
</api>



This code alwasys create the file with the name add, even if I set the
ReplyFileName property.

If I use this same sequence in a ProxyService it works fine. And creates
the file with the correct name.

Is there any additional configuration that should be done for this to work
in Rest apis?

Thanks,
