Use one condition with multiple flow steps

[marcusdoron]

In the Preflow I have several steps that should run only if a condition is fulfilled.

Is there a way to set the same condition to a group of steps, instead of setting the condition for each step and duplicating the code?

You can use shared flow and put the shared flow with condition.

[marcusdoron]

Thanks. I am familiar with this option. But shared flows are supposed to be shared between proxies.

In this case, the flow segment is part of only one proxy, and I would not like to develop one proxy in two places.

Then you can put a conditional flow, and add all the policies to that. This will execute only when your condition is true. Note, if you have another conditional flow, then don't use this option.

Yes, here's an example.

But this is not in the PreFlow, Kurt?

[kurtkanaskie]

Right, my bad, this looks good but will only execute one conditional flow.

No, not in the preflow. This is not possible:

<PreFlow name='preflow'>
  <Request>
    <Series> <!-- this is not valid -->
      <Step><Name>Step-1</Name></Step>
      <Step><Name>Step-1</Name></Step>
      <Step><Name>Step-1</Name></Step>
      <Step><Name>Step-1</Name></Step>
      <Condition> flow.variable = "yes"</Condition>
    </Series>
  </Request>
</PreFlow>
  

There is no way to wrap a condition around multiple steps in the preflow without repeating the condition. This way:

<PreFlow name='preflow'>
  <Request>
    <Step>
      <Name>Step-1</Name>
      <Condition> flow.variable = "yes"</Condition>
    </Step>
    <Step>
      <Name>Step-1</Name>
      <Condition> flow.variable = "yes"</Condition>
    </Step>
    <Step>
      <Name>Step-1</Name>
      <Condition> flow.variable = "yes"</Condition>
    </Step>
    <Step>
      <Name>Step-1</Name>
      <Condition> flow.variable = "yes"</Condition>
    </Step>
  </Request>
</PreFlow>

Wrapping the series of steps into a sharedflow works, as Priyadarshi pointed out. But if you don't want to "share" the series of steps outside the proxy, then... not.

This is a limitation of the Apigee DSL.
