Route to different hosts based on another http api result

[Ho Felix]

hi,

Just wonder if it is possible to implement an api checking in serviceProxy and the api result decides which target host to go.  

How can this be done in proxies.xml?

<serviceProxy>

<! --    if http://checkapi returns '1'  -->

<target host="host_success"/> 

<! --    else if http://checkapi returns '0'  -->

<target host="host_fail"/>

</serviceProxy>

Thanks in advance,

Felix

Hi Felix,

just use an Groovy interceptor, call the API and set the destinations list accordingly. Have a look at the code oft he ContentBasedRouter interceptor for reverece:

 

https://github.com/membrane/service-proxy/blob/master/core/src/main/java/com/predic8/membrane/core/interceptor/cbr/XPathCBRInterceptor.java

 

Look at line 73 & 74.

 

Cheers,

Thomas

Hello Felix,

i just had a similar problem and i solved it like this:

<groovy>

[...]
      exc.getDestinations().clear();
      exc.getDestinations().add("http://yourTarget:port" + exc.getOriginalRequestUri());
      return CONTINUE;

</groovy>

[...]

This is how you set the destination of the exchange directly, just like Thomas hinted. You can then leave out the "target" in the service proxy.
