我使用APIKIT Router创建了我的流程。raml main flow+post:/XX flow。主流和我的POSt流都有错误处理组件。
主流。
<flow name="raml-main">
<http:listener .....">
<http:response statusCode="#[vars.httpStatus default 200]">
<http:body ><![CDATA[ ]]></http:body>
<http:headers><![CDATA[#[vars.outboundHeaders default {}]]]></http:headers>
</http:response>
<http:error-response statusCode="#[vars.httpStatus default 500]">
<http:body ><![CDATA[#[output application/json --- error.description]]]>
</http:body>

</flow>
如果我在POST流或RAML主流下更新Transform处理器下的payload,它从来没有反映在输出中。比如目前我收到400个坏的请求。
在Transform组件中,如果我改变了消息,就得不到我修改后的消息。
为什么会这样?

400意味着没有这样的终点。这意味着你的流永远不会被调用。有另一个Mule正在监听的端点。幸运的是,Mule报告了url是错误的,以及它正在监听什么样的url。像这样
INFO 2020-05-07 07:32:22,539 [http.listener.06 SelectorRunner] org.mule.service.http.impl.service.util.DefaultRequestMatcherRegistry: No listener found for request: (GET)/badurl
INFO 2020-05-07 07:32:22,539 [http.listener.06 SelectorRunner] org.mule.service.http.impl.service.util.DefaultRequestMatcherRegistry: Available listeners are: [([*])/console/*, ([*])/, ([*])/api/*]
当然,如果你打到了另一个服务器或另一个端口或协议,那么什么都不知道这个请求。但是,既然你有了答案--400,那么你可能撞到了你的服务器。

默认的错误处理程序和响应也可以在响应-错误响应部分的http监听器中进行设置
HTTP响应400坏请求意味着HTTP请求不符合预期的格式。有可能是APIKit正在根据RAML验证请求。在这种情况下,APIKit将引发错误,并且它将不会执行 post:\notifications:raml-config
流程。你是否已经确认了流程的执行,例如用记录仪?
