题目链接：http://www.wechall.net/challenge/training/encodings/url/index.php

题目：

很明显的url解码即可，python脚本如下：

import urllib.parse

rawurl = "%59%69%70%70%65%68%21%20%59%6F%75%72%20%55%52%4C%20%69%73%20%63%68%61%6C%6C%65%6E%67%65%2F%74%72%61%69%6E%69%6E%67%2F%65%6E%63%6F%64%69%6E%67%73%2F%75%72%6C%2F%73%61%77%5F%6C%6F%74%69%6F%6E%2E%70%68%70%3F%70%3D%68%72%6D%64%65%69%6C%69%64%6E%69%61%26%63%69%64%3D%35%32%23%70%61%73%73%77%6F%72%64%3D%66%69%62%72%65%5F%6F%70%74%69%63%73%20%56%65%72%79%20%77%65%6C%6C%20%64%6F%6E%65%21"

url = urllib.parse.unquote(rawurl)

print (url)

运行结果如下：

解码结果为：Yippeh! Your URL is challenge/training/encodings/url/saw_lotion.php?p=hrmdeilidnia&cid=52#password=fibre_optics Very well done!

刚开始以为flag是fibre_optics，但发现Submit后没反应，后来看了讨论区的提示，在地址栏中加上解码出来的Url，如下图，得解：

最终的链接为http://www.wechall.net/challenge/training/encodings/url/saw_lotion.php?p=hrmdeilidnia&cid=52#password=fibre_optics
