WSO2 API properties in custom handler

Question

How can I access the API related information like API Properties (defined in publisher) in the WSO2 Custom handler?

Answer 1

You can use message context object to access API information:

messageContext.getProperty("api.ut.HTTP_METHOD")

Refer sample for more info.

Answer 2

Refer the below code. It will print all the messagecontext property key set and their values.

        Set propertySet = context.getPropertyKeySet();
    for (Object propertyKey : propertySet) {

        log.info("Key: " + propertyKey.toString() + "| value: "
                + context.getProperty(propertyKey.toString()));
    }

Answer 3

As I can see handler/mediator can have access to api properties via local registry

When defined in xml configuration it can be like this

<sequence name="custom-sequence" xmlns="http://ws.apache.org/ns/synapse">
  <log level="custom">
      <property 
        name="prop"
        expression="get-property('registry', 
          fn:concat(
            'gov:/apimgt/applicationdata/provider/',
            $ctx:api.ut.apiPublisher, '/',
            $ctx:api.ut.api, '/',
            $ctx:api.ut.version, '/',
            'api@api_meta.my_property'
          ))" />
  </log>
</sequence>
