In the URL transfer + to%2b to the problem of variable space

An encrypted string, after passing through the URL can not be decrypted.

Original string:

H1tqymmnx7jdvowi9knaem5dhfamj+r barnvhwhumravyxpa2agzszx5k9k0qdhiquq7m42spnbmdgtk11sza9n4tvubdpaar1axfbjwxblt20dy7ftyvxipmlwnsmx/v2j0kkjhvry=

UrlEncode after the string:

H1tqymmnx7jdvowi9knaem5dhfamJ%2bR Barnvhwhumravyxpa2agzszx5k9k0qdhiquq7m42spnbmdgtk11sza9n4tvubdpaar1axfbjwxblt20dy7ftyvxipmlwnsmx%2fv2j0kkjhvry %3d

The string received through $_get:

H1tqymmnx7jdvowi9knaem5dhfamJ R barnvhwhumravyxpa2agzszx5k9k0qdhiquq7m42spnbmdgtk11sza9n4tvubdpaar1axfbjwxblt20dy7ftyvxipmlwnsmx/v2j0kkjhvry=

Compare found, + turn into%2b, received when the time becomes a space.

Workaround:

UrlEncode two times before the pass: UrlEncode (UrlEncode ($STR))

Two times after the UrlEncode the string became:

H1tqymmnx7jdvowi9knaem5dhfamJ%252bR barnvhwhumravyxpa2agzszx5k9k0qdhiquq7m42spnbmdgtk11sza9n4tvubdpaar1axfbjwxblt20dy7ftyvzuuepw% 252f26rav2j0kkjhvry%253d

The wonderful thing is, through the thinkphp $_get received the string without decode, directly is normal string:

H1TQYMMNX7JDVOWI9KNAEM5DHFAMJ+ rbarnvhwhumravyxpa2agzszx5k9k0qdhiquq7m42spnbmdgtk11sza9n4tvubdpaar1axfbjwxblt20dy7ftyvxipmlwnsmx/v2j0kkjhvry=

Other systems to decode once ...
