Passport JWt Authetication for hyperledger composer API - mongodb

Question

call back for access tokenI am searching for a solution to implement passport jwt authetication strategy for hyperledger composer REST API. I have followed this link for setting up passport authetication https://www.codementor.io/gangachris125/passport-jwt-authentication-for-hyperledger-composer-rest-server-jqfgkoljn.
Generating hyperledger composer API,creating composer rest server docker container , API's are protected everything seems working except the access token generation , how to retrieve that token.
Also i created another nodejs application with passport jwt, mongodb with few users added. I was able to succesfully generate token from that application and protect any express routes using that token.
But my struggling point is how to generate token for the composer rest server API
As explained in many articles i have created custom jwt , environment varibales as follows
custom jwt
const passportJwt = require('passport-jwt');
const util = require('util');
function CustomJwtStrategy(options, verify) {
options.jwtFromRequest = passportJwt.ExtractJwt.fromAuthHeaderAsBearerToken();
passportJwt.Strategy.call(this, options, verify);
}
util.inherits(CustomJwtStrategy, passportJwt.Strategy);
module.exports = {
Strategy: CustomJwtStrategy
};
Environment variables
COMPOSER_CARD=admin#tutorial-network
COMPOSER_NAMESPACES=never
COMPOSER_AUTHENTICATION=true
COMPOSER_MULTIUSER=true
COMPOSER_PROVIDERS='{
"jwt": {
"provider": "jwt",
"module": "/home/composer/node_modules/custom-jwt.js",
"secretOrKey": "admin",
"authScheme": "saml",
"successRedirect": "/",
"failureRedirect":"/"
}
}'
COMPOSER_DATASOURCES='{
"db": {
"name": "auth",
"connector": "mongodb",
"host": "mongo"
}
}'
composer rest server logs on startup
Now from where should i generate the token, how to retrive that token so that i can capture and pass it in headers for the hyperledger composer business API's.
Please help with details.

You can use the token generated by node js. One thing you need to take care is you have to use same here "secretOrKey": "admin" customkey with which you are generating token in node js
Make request as shown in an image as you are using options.jwtFromRequest =passportJwt.ExtractJwt.fromAuthHeaderAsBearerToken(); . It will store the access_token in cookie. Then you can retrieve it from cookie for further use.
