Python的Bottle框架中獲取制定cookie的教程

這篇文章主要介紹了Python的Bottle框架中獲取制定cookie的教程,主要是針對別的路徑而不是當(dāng)前頁面的cookie,需要的朋友可以參考下

這兩天為用bottle+mongodb寫的一個項目加上登錄功能,無奈怎么都獲取不到保存的cookie,文檔給出讓我們這樣操作cookie的代碼片段:

@route('/login')

def login ():

username = request .forms .get('username ')

password = request .forms .get('password ')

if check_user_credentials(username, password):

response .set_cookie("account", username, secret= 'some-secret-key')

return "Welcome %s!You 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

雖然文檔上沒有但是還有一種操作cookie的方式:

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

但是無論我用哪種方式操作我都無法獲取cookie,為什么呢.百思不得其解.但是我的一個處理文章點擊率的提醒了我,代碼如下:

@route('/archrives/:aid#\d+#')

def article_show(aid):

db = dbconn.ConnDB()

artid = int(aid)

# 獲取客戶端ip

remoteip = request.environ.get('REMOTE_ADDR')

artcookie = remoteip+'ip'+aid

print request.COOKIES.keys()

# 判斷cookie是否存在

if artcookie in request.COOKIES.keys():

# 存在則更新有效時間

response.COOKIES[artcookie] = True

response.COOKIES[artcookie]['max-age'] = 500

else:

# 不存在則更新文章查看次數(shù)

db.posts.update({"id":artid}, {"$inc":{"views":1}})

# 并設(shè)置cookie

response.COOKIES[artcookie] = True

response.COOKIES[artcookie]['max-age'] = 500

TEMPLATE['posts'] = getArtList({"id":artid})

TEMPLATE.update(setTempVar())

return template('article.html', TEMPLATE)

這里是可以正常獲取到cookie的,而且代碼沒有任何區(qū)別.唯一的區(qū)別就是用戶認證是跳轉(zhuǎn)了頁面.所以我help了一下:

from bottle import response

help(response.set_cookie)

help的結(jié)果其中有兩個參數(shù)一個是path,和domain:

:param domain: the domain that is allowed to read the cookie.

(default: current domain)

:param path: limits the cookie to a given path (default: current path)

明顯bottle的cookie默認只在當(dāng)前路徑下能讀取的到,所以要別的頁面讀取到cookie我們的代碼須改成如下:

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']

這樣我們就能在別的路徑下訪問我們設(shè)定的cookie.
