spring - Calling secured endpoint by scheduler using Feign Client -


i have simple microservices architecture:

  • api gateway
  • service registry
  • uaa service (user data , token generation; use oauth2 , jwt)
  • core services, let's service_a , service_b

the flow looks this: user gives credentials, api gateway passes them uaa-service, being validated, uaa-service generates jwt , returns user. access token attached every request, service_a , service_b can authenticate , authorize incoming requests. nothing fancy it.

the problem i've created scheduler, running in service_a, gathers data service_a , service_b , saves in database. problem is, endpoints of service_b secured , need access token able call service_b.

how should deal such issues? can see 3 options:

  • copy keystore.jks uaa-service service_a , generate token manually
  • replace oauth simple basic authentication service_b endpoints
  • generate manually jwt validity set 20 years, store in service_b , use forever

neither of nice solutions, 1 option 3.

thoughts?

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
