Adding non user field to payload for use in JWT token

Question

Hi I'm looking to add a non user field to the payload in the auth process so I can included in the JWT token.

The request is like this:

{ "scriptId": "script1", "password": "password", "userName": "user1" }

config is like this:

  "auth": {
    "local": {
      "usernameField" : "scriptId"
    },
    "token": {
      "secret": "mysecret",
      "payload": ["scriptId","userName"],
      "expiresIn": "10min"
    },
    "successRedirect": "/chat.html"
  }

How can I pass the userName parameter so I can retrieve it in the before hook of the auth/token service so I can it to the hook.data

Or if there's a better way to do it just let me know.

Check this PR:

// default.json
{
  "auth": {
    "extraFields": [
      "email",
      "roles"
    ]
  }
}

The extraFields are fieldnames of your user object. So data that goes in the JWT needs to be provided by your user endpoint.

you can add this in following way

app.service('authentication').hooks({
    before: {
      create: [
        authentication.hooks.authenticate(config.strategies),
        function (hook) {
         hook.params.payload = {
            userId: hook.params.user.userId,
            accountId: hook.params.user.accountId
          };
          return Promise.resolve(hook);
        }
      ],
      remove: [
        authentication.hooks.authenticate('jwt')
      ]
    }
  });

create an after hook called add_payload (or whatever u want) for service authenticate using the command 'feathers generate hook'
inside /src/service/authentication/index.js add inside the end of the export

app.service('/auth/local').after(hooks.after);

create index.js file in /src/service/authentication/hooks, the contents should look like:

'use strict' const addPayload = require('./add_payload'); const globalHooks = require('../../../hooks'); const hooks = require('feathers-hooks'); exports.after = { all: [addPayload()], find: [], get: [], create: [], update: [], patch: [], remove: [] };

inside the hook function... /src/service/authentication/hooks/add_payload.js

return function(hook) { hook.result.aa = "xyz"; // add whatever you want to the return here... hook.addPayload = true; };
