Chaining of Processor Using Chain Adapter

Processors can be chained using a chain adapter in an untethered environment and in a tethered environment.

Chaining Processors in an Untethered Environment

Procedure

  1. In the Configuration Manager, click the Endpoints tab and then click Call Transformation.



  2. In the Adapter field, input the name of the chain adapter. For example, com.mashery.proxy.customer.generic.oauth2-jwt-authenticator.
  3. As per your requirement, select the checkbox for Perform Preprocess/Perform Postprocess or both.
  4. In the Preinputs field, type the processors to be chained. The name of the processor is the processor's bean name. The syntax is: 
    processors:PROCESSOR1,PROCESSOR2

    For example: 

    processors:com.mashery.local.MasheryCustomProcessorOne,com.mashery.local.MasheryCustomProcessorTwo

    You can also provide configuration data as input. The syntax is: 

    PROCCESSOR1.parameter:value
PROCCESSOR1.parameter:value
PROCCESSOR2.parameter:value
PROCCESSOR2.parameter:value
    Note:
    • In the pre-input configuration, there must not be more than one key with name "processors".
    • The processors to be chained must be input as comma separated list.
  5. In the Postinputs field, input the name of the processor that the traffic manager can use to post-process the calls, then click Save.
    Note:
    • The input syntax for the Postinputs fields must be the same as that of the Preinputs field.
    • If you opt for only Perform Postprocess, the input for Postinputs field must be as follows: 
      processors:com.mashery.local.MasheryCustomProcessorOne

      and 

      PROCESSOR1.parameter:value
PROCESSOR1.parameter:value

Chaining Processors in a Tethered Environment

The process for chaining processors in a tethered environment is the same as that of untethered. The interface of the control center appears as shown below:



What to do next

To test the changes, use the endpoint and make a traffic call.
