Flask learning: the use of routing requests

1. Set request method

from Flask Import the Flask 

App = the Flask ( the __name__ ) 

# the Flask defined route is achieved by decorator 
# routed by default only supports GET, if set other, specify their own 
@ app.route ( " / index " , Methods = [ ' the GET ' , ' the POST ' ])
 DEF index ():
     return  " setting mode request " 

# 4 launcher 
IF  the __name__ == ' __main__ ' : 
    app.run ()

2. Request Processing Parameters

from Flask Import the Flask 

App = the Flask ( the __name__ ) 

# <> define the routing parameters, <> need a name within 
@ app.route ( " / User / <user_id> " )
 DEF The get_user (user_id):
     # required in view of the function fill in the name of the parameter, the default parameter type is a string. Required parameter conversion type int: <int: user_id> 
    return  " acquired user S% " % user_id 

# 4. launcher 
IF  the __name__ == ' __main__ ' : 
    app.run ()
