Stop resource path from appending to Backend server

[#1]

I am learning Apigee..

I have a proxy, that is calling default TargetEndpoint and pointed to httpbin.org. I am trying to add a resource /report to my proxy. Intention is send the requests for service v1/myservice/report to httpbin.org. Either using same Target Endpoint or a new one...However, the proxy seems to append the /report resource path to my backend (httpbin.org) requests. How to avoid this? What is the best way to do this?

The behavior you describe is as designed and documented.

You can disable the behavior by setting a specific context variable: target.copy.pathsuffix

Set it to false, in the target flow.

You can do this with an assignMessage policy, or with a JavaScript policy. Examples follow.

Option 1:

<AssignMessage name='AM-TCPS-False'>
  <AssignTo createNew='false' type='request'/>
  <AssignVariable>
    <Name>target.copy.pathsuffix</Name>
    <Value>false</Value>
  </AssignVariable>
</AssignMessage>

Or, option 2:

<Javascript name='JS-TCPS-False'>
  <ResourceURL>jsc://setTargetCopyPathSuffixFalse.js</ResourceURL>
</Javascript>

and for the latter, here is the JS:

context.setVariable('target.copy.pathsuffix', false);

In either case, you must attach the policy in the Request Flow of the Target. Something like this:

<TargetEndpoint name="default">
    <Description/>
    <Flows/>
    <HTTPTargetConnection>
        <Properties/>
        <URL>http://httpbin.org</URL>
    </HTTPTargetConnection>
    <PreFlow name="PreFlow">
        <Request>
           <Step><Name>AM-TCPS-False</Name></Step>
        </Request>
        <Response/>
    </PreFlow>
    <PostFlow name="PostFlow">
        <Request/>
        <Response/>
    </PostFlow>
</TargetEndpoint>

Good luck!
