Question

我使用全局传出日志中介，以便在调用Web服务时获取完整的日志记录消息。当客户端使用SOAP Web服务时，一切都井然有序。当客户端调用REST Web服务时，会发生异常，并且响应是运行时错误。

除了为每个服务制作调解员而不是全局服务之外，我能做些什么吗？

这是调解员定义

<sequence xmlns="http://ws.apache.org/ns/synapse" name="WSO2AM--Ext--Out">
<log level="full">
    <property name="ParentID:" expression="get-property('parentID')"/>
    <property name="ActualRemoteAddress:" expression="get-property('client')"/>
    <property name="AuthHeader:" expression="get-property('AuthHeader')"/>
</log>

这是异常的开始

当您使用内容感知中介（例如，logmediator）时，网关会将有效负载构建为soap格式。这是通过axis2.xml中定义的messagebuilders完成的。根据有效负载的内容类型，将选择正确的messagebuilder。

在您的有线日志中，网关从后端获取带有content-type -application / json的有效负载。但有效负载（＆＃34; Hello，me＆＃34;）不是实际的json格式。因此，与之相关的构建器无法解析有效负载
