WSO2 ESB中的API仅返回JSON的第一个节点？

Question

我已经在WSO2企业服务总线中创建了REST API。 该API调用SoapUI上的模拟服务，该服务返回具有2个节点的JSON：

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

ESB应该返回此JSON，但始终忽略第二个节点（“ msg”），而仅返回第一个节点。

我已经更改了位置，类似这样，但是不起作用：

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

该API非常简单，类似于：

<?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>

我已经检查过模拟了，它对ESB的回答正确

为什么我的API仅返回第一个节点？

Answer 1

理想情况下，它不能返回任何东西。 在<outSequence/>添加<send/>介体应该可以解决此问题。 您可以启用电汇日志，否则进行检查。

Answer 2

我猜想，消息流可能无法正确识别json格式。 请按以下步骤更改顺序并尝试：

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

对于复杂的JSON响应，您可以使用：

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