How to write repeating Regex pattern in JavaScript -


how write regex following pattern in javascript:

1|dc35_custom|3;od;czy;gl|2;ob;bnp;mt|4;sd;abc;mt|5;ih;dft;fr|6;oh;aqw;mt|7;ip;can;mt|8;op;car;mt|9;ec;smo;gl|10;do;czt;ku|

where

  • the first part 1|dc35_custom| fixed.
  • the second part onwards, pattern repeats 9 times(i.e. 3;od;czy;gl| 2;ob;bnp;mt| , on.

the 1st character in ranges 2-11 , should not repeat. example 3 appears in first pattern, should not appear again.

i'm making lot of assumptions this, here's crack @ it:

1\|dc35_custom\|(([2-9]|10|11);[a-z]{2};[a-z]{3};[a-z]{2}\|){9}

how works

  • 1\|dc35_custom\| literal text, escaping vertical bar operators
  • ([2-9]|10|11) match number 2 11.
  • [a-z]{2} match 2 lowercase letters
  • [a-z]{3} match 3 uppercase letters
  • [a-z]{2} match 2 uppercase letters
  • {9} looks 9 consecutive matches of entire sequence enclosed in parentheses

it not, amadan points out, check uniqueness, because that's bit beyond regex for.

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.
