Text inside ##

Google Cloud Apigee
1

Hello,

I am trying to understand an api in apigee and I find some lines of text inside ## between the steps of the flow. I can’t find in the documentation what it’s the use for it, so I don’t know what this is doing.

Can someone explain?

<PreFlow name="PreFlow">
  <Request>
    <Step>
      <Name>Assign.CopyRequestHeaders</Name>
    </Step>
    <Step>
      <Name>JsCall.GenerateAndAssignFlowVariables</Name>
    </Step>
    #api_data_retrieval#
    #configuration_constants_read#
    #access_transaction_id#
    #security_protection_xss#
    #JsCall.Logging.ULFF#
    #spike_arrest#
    #throttling_quota_api_1min#
    #access_payload_size#
    #access_content_negotiation#
    #validation_content_type#
    <Step>
      <Condition>((originalVerb == "POST") or (originalVerb == "PUT") or (originalVerb == "PATCH"))</Condition>
      <Name>Jsc.ValidateRequestPayloadStructure</Name>
    </Step>
    <Step>
      <Name>ExtractRequestId</Name>
    </Step>
    #network_cors_simple_req#
  </Request>
  <Response/>
</PreFlow>

That looks like a template to me.

Apigee Edge doesn’t interpret text inside #.

I can imagine a templating engine that takes the text you provided and inserts specific content where #spike_arrest# appears, and so on, resulting in a valid, complete API Proxy Endpoint configuration.

I don’t know of a templating tool that has been used like this with Apigee Edge. Having said that, it wouldn’t be hard to produce and it’s possible that there’s a common one I don’t know about.
