如何避免在WSO2 EI中使用响应调解器忽略下一个调解器？

Question

I have a REST service that returns a json simple {message: "ok"}. When I use Respond Mediator this stop further processing of a message and send the message back to the client.

I need to send response to client, and then execute task asynchronously, but if I use it ignores the next call to a sequence or an endpoint.

How can you respond synchronously (response to client) and then invoke a service, without response mediator ignore the next mediator?

thanks;

Answer 1

I was able to solve the challenge. effectively Clone mediator not just clone message, it give new separate life to new message.

 <api xmlns="http://ws.apache.org/ns/synapse" name="porticApiAsyn" context="/test">
<resource methods="POST" url-mapping="/asyn">
  <inSequence>
     <log>
        <property name="message" value="asyn"/>
     </log>
     <payloadFactory media-type="json">
        <format>{"message":"asyn test"}</format>
        <args/>
     </payloadFactory>
     <clone continueParent="true" sequential="true">
        <target sequence="logSequence"/>
     </clone>
     <respond/>
  </inSequence>

In this case, the message is sent to logsequence, then the response mediator is executed. Thanks for your help.

For your case you could even do the following

<api xmlns="http://ws.apache.org/ns/synapse" name="porticApiAsyn" context="/test">
<resource methods="POST" url-mapping="/asyn">
  <inSequence>
     <log>
        <property name="message" value="asyn"/>
     </log>
     <payloadFactory media-type="json">
        <format>{"message":"asyn test"}</format>
        <args/>
     </payloadFactory>
     <clone continueParent="true" sequential="true">
        <target sequence="logSequence"/>
        <target>
          <sequence>
            <respond/>
          </sequence>
        </target>
     </clone>
  </inSequence>

I guess it should work as well and is maybe more readable
