[Kimchi-devel] [PATCH V2] add a base64 safe url encode and decode to js utils

From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com&gt; Most webs use safe url base64 encode/decode to escape the special characters. base64 encode/decode is similar to base64 safe url encode/decode. The difference is the alphabet. The base64 safe url alphabet uses '-' instead of '+' and '_' instead of '/'. after this patch: In backend, we can encode an url: 'L3ZuY19hdXRvLmh0bWw_cG9ydD02NDY2NyZwYXRoPT90b2tlbj1vcGVuc3VzZTEyJmVuY3J5cHQ9MQ==' and in UI, we can decode it: kimchi.urlSafeB64Decode("L3ZuY19hdXRvLmh0bWw_cG9ydD02NDY2NyZwYXRoPT90b2tlbj1vcGVuc3VzZTEyJmVuY3J5cHQ9MQ==") "/vnc_auto.html?port=64667&path=?token=opensuse12&encrypt=1" or In UI, we can encode an url: kimchi.urlSafeB64Encode("/vnc_auto.html?port=64667&path=?token=opensuse12&encrypt=1") "L3ZuY19hdXRvLmh0bWw_cG9ydD02NDY2NyZwYXRoPT90b2tlbj1vcGVuc3VzZTEyJmVuY3J5cHQ9MQ==" and in backend, we can decode it: '/vnc_auto.html?port=64667&path=?token=opensuse12&encrypt=1' Safe url base64 is a variant of base64.
