Add header with username into request to backend in wso2 apimanager

Question

I have apimanger v1.5.0. It authorize request by access_token and forward to backend. Backend need enduser name for processing request. I do not want add JWT-headers to request because that insecure.

Apimanager can add optional headers to request, if add to file repository/deployment/server/synapse-configs/default/api/admin--common_v1.0.1.xml in section <outSequence><header> some data for example uri.var.accessToken. But I dont know name of variable with enduser name. Does somebody know?

Answer 1

Variable name is END_USER_NAME.

Example of use:

<inSequence>
        <property name="POST_TO_URI" value="true" scope="axis2"/>
        <property name="X-Test-Username" scope="transport" expression="get-property('END_USER_NAME')"></property>
        <filter source="$ctx:AM_KEY_TYPE" regex="PRODUCTION">

And result in http headers:

GET http://backend.server:8080/sm/api/v1/common/user/example?access_token=4d758b64d5de15029c467dcd6feb354& HTTP/1.1
Accept-Language: ru-RU,ru;q=0.8,en-US;q=0.6,en;q=0.4
Username: rudesu@example.com
Referer: https://example.com/src-jssip-osdk-test/
Accept-Encoding: gzip,deflate,sdch

THIS METHOD DOESN`T WORK IN APIM 1.7.0

In 1.7.0 work: <property name="X-Test-Username" scope="transport" expression="get-property('END_USER_NAME')"/>
