Flask of 03 study notes routing

1. endpoint

from Flask Import Flask, the url_for
 # instantiate an object is Flask 
App = Flask ( the __name__ )
 # print default configuration information 

# redistribute development environment 
app.config.from_object ( ' settings.DEV ' ) 


# introduced into the production environment configuration 
# App. config.from_object ( 'settings.Pro') 



@ app.route ( ' / index ' , Methods = [ ' the GET ' , ' the POST ' ], endpoint = ' XX ' )
 DEF index ():
     "" " 
        If no endpoint ,The default is the name of the function
        Can be reversed by url_for generation request URL 
    "" " 
    Print (url_for ( ' XX ' ))
     return  ' Ni de mA, ZA Hui Shi! ' 

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

 

Print Results:

 

 

2. Dynamic Routing

app.route @ ( ' / index / <int: ID> ' , Methods = [ ' the GET ' , ' the POST ' ])
 DEF index (ID):
     "" " 
        If no endpoint, the function name is a default 
        by url_for can reverse generation request URL 
    "" " 
    Print (ID)
     return  ' Ni de mA, ZA Hui Shi! '

 

 

 

 

 

Description: <int: id> here <> java equivalent dynamic routing {}, int parameter indicating the type of string type indicates not write

 

app.route @ ( ' / index / <int: ID> ' , Methods = [ ' the GET ' , ' the POST ' ])
 DEF index (ID):
     "" " 
        If no endpoint, the function name is a default 
        by url_for can reverse generation request url 
    "" " 
    Print (url_for ( ' index ' , the above mentioned id = 1))   # reverse route generation, which is a little sad the 
    Print (the above mentioned id)
     return  ' Ni de mA, ZA Hui shi! '
