In Python's bottle framework, get a tutorial on making cookies _python

These two days for a project written with Bottle+mongodb plus login function, but how can not get the saved cookies, the document gives us this operation cookies code fragment:

@route ('/login ')
def login ():
   username = Request. Forms. Get (' username ')
   password = Request. Forms. Get (' PA ssWOrd ')
   if check_user_credentials (username, password):
      response. Set_cookie ("Account", username, secret= ') Some-secret-key ') return
      "Welcome%s! You are are now logged in.% username
   Else: return
      "Login failed." 

@route ('/restricted ')
def restricted_area ():
   username = Request. Get_cookie ("account", secret= ' Some-secret-key ')
   if username: return
      "Hello%s.welcome back."% username

Although there is no documentation but there is a way to manipulate cookies:

From bottle import request, Response

@route ('/login ', method= "POST")
def login ():
  user = Request. post[' user ']
  passwd = Request. post[' passwd ']

  if Check_user_right (USER,PASSWD):
    response. cookies[' account ' = user
  else: pass

@route ('/admin ')
def admin ():
  user = Request. cookies[' user '
  if User: Pass
    

But no matter which way I operate I can not get cookies, why not. Baffled. But one of my handling articles was a click-through rate that reminded me of the code as follows:

@route ('/archrives/:aid#\d+# ')
def article_show (aid):
  db = Dbconn. Conndb ()
  artid = Int (aid)
  # get client IP
  remoteip = request.environ.get (' remote_addr ')

  Artcookie = remoteip+ ' IP ' +aid
  print request. Cookies.keys ()

  # Determines whether the cookie exists
  if Artcookie in request. Cookies.keys ():
    # exists to update the active time
    response. Cookies[artcookie] = True
    response. cookies[artcookie][' max-age '] = +
  else:
    # does not exist update Article view Count
    db.posts.update ({"id": ArtID}, {"$inc": {" Views ": 1}})

    # and set the cookie
    response. Cookies[artcookie] = True
    response. cookies[artcookie][' max-age '] = +

  template[' posts '] = Getartlist ({"id": ArtID})
  Template.update ( SetTempVar ()) Return

  template (' article.html ', template)

This is a normal way to get cookies, and the code doesn't make any difference. The only difference is that user authentication is a jump to the page. So I help a bit:

From bottle import response help
(Response.set_cookie)

The result of Help has two parameters, one is path, and domain:

 :p Aram Domain:the Domain is allowed to read the cookie.
   (default:current domain)
  :p Aram Path:limits The cookie to a given path (default:current path)

Obviously bottle cookies are only readable by default in the current path, so the code to read cookies to another page should be changed as follows:

From bottle import request, Response

@route ('/login ', method= "POST")
def login ():
  user = Request. post[' user ']
  passwd = Request. post[' passwd ']

  if Check_user_right (USER,PASSWD):
    response. cookies[' account ' = user
    response. cookies[' account ' [' path '] = '/admin '
  else:
    pass

@route ('/admin ')
def admin ():
  user = Request. cookies[' user ']

So that we can access the cookie we set under another path.
