java - Corba Async call issue -


i have following requirements:

implement simple pipelined job service (further pjs). client writes simple application form , put pjs. pjs consists of several individual processes handles application in sequential order:

  • verifier responsible verification of application form format. might simple handling mechanism i.e. check matching user individual identity number (id) in database (you can use simple text file).
  • acknowledger receives verified application form , assigns unique identificator (autoincrement id or uuid).
  • hr receives application form acknowledger assigned unique number, put database , generate notification original sender (client) message receives application form. response have piggybacked unique number assigned acknowledger.

there should no intermediaries involved in process of forwarding job between servers: i.e. each server should pass application directly next server. stay focus on system architecture , process of passing applications around. don’t implement complex data structures represent application. can simple tiny json message.

how implement task? don't know how return response hr part client directly, because client starts calling verifier.

i've understood problem , solved myself, posting github link: pjs

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
