Question & Answer :
I’m making an attempt to compose a Java people to log successful to a definite web site. The information dispatched successful the Station petition to log successful is
person%5Blogin%5D=username&person%5Bpassword%5D=123456
I’m funny what the %5B and %5D means successful the cardinal person login.
However bash I decode these information?
Arsenic per this reply complete present: str='foo%20%5B12%5D' encodes foo [12]:
%20 is abstraction %22 is quotes %5B is '[' and %5D is ']'
This is known as p.c encoding and is utilized successful encoding particular characters successful the url parameter values.
EDIT By the manner arsenic I was speechmaking https://developer.mozilla.org/en-America/docs/JavaScript/Mention/Global_Objects/encodeURI#Statement, it conscionable occurred to maine wherefore truthful galore group brand the aforesaid hunt. Seat the line connected the bottommost of the leaf:
Besides line that if 1 needs to travel the much new RFC3986 for URL’s, making quadrate brackets reserved (for IPv6) and frankincense not encoded once forming thing which may beryllium portion of a URL (specified arsenic a adult), the pursuing whitethorn aid.
relation fixedEncodeURI (str) { instrument encodeURI(str).regenerate(/%5B/g, '[').regenerate(/%5D/g, ']'); }
Hopefully this volition aid group kind retired their issues once they stumble upon this motion.
