WSO2 ESB中的API仅返回JSON的第一个节点？

Question

I've created a REST API in WSO2 Enterprise Service Bus. The API calls to a mock service on SoapUI that returns a JSON with 2 nodes:

{
    "customer" : {
        "value1": "2312",
        "value2": "3214",
        "value3": "4214"
    },
    "msg" : "error"
}

The ESB should return this JSON, but it always ignores the second node ("msg") and return just the first node.

I've already changed the position, something like this, but it doesn't works:

{
    "msg" : "error",
    "customer" : {
        "value1": "2312",
        "value2": "3214",
        "value3": "4214"
    }
}

The API is really simple, something like this:

<?xml version="1.0" encoding="UTF-8"?>
<api context="/test1" name="test" xmlns="http://ws.apache.org/ns/synapse">
  <resource methods="POST" protocol="http">
    <inSequence>
      <send>
        <endpoint key="conf:/endpoint.xml"/>
      </send>
    </inSequence>
    <outSequence/>
    <faultSequence/>
  </resource>
</api>

I've already checked the mock and it's answering right to ESB

Why my API is returning only first node?

Answer 1

Ideally this cannot return anything. Adding <send/> mediator inside <outSequence/> should fix the problem. You may enable wire logs and check otherwise.

Answer 2

As I guess, message flow may not identify json format correctly. Please change out sequence as follows and try this out:

<outSequence xmlns="http://ws.apache.org/ns/synapse">
<property name="messageType" value="application/json" scope="axis2" type="STRING"></property>
<send/>
</outSequence>

For complex JSON responses you can use:

<outSequence xmlns="http://ws.apache.org/ns/synapse">
<property name="messageType" value="application/json/badgerfish" scope="axis2" type="STRING"></property>
<send/>
</outSequence>
