to the routing added reason regular: When the actual development, URL in often with a lot of parameters, for example: /add/0000007.html, wherein 
000007 (stock code means: extracts the corresponding database may be used for recording) is the parameter, 
if this time is not regular, then we should write N times @route, the corresponding function is added to the dictionary in which case the key to the dictionary there are N, waste of space, 
if regular, then only need to write one @route to complete multiple URL, such as correspondence /add/00007.html,add/000036.html the same function, when the key-value dictionary of 
a lot less
