Python的Bottle框架中獲取制定cookie的教程

 　　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,無奈怎麼都獲取不到保存的cookie,文檔給出讓我們這樣操作cookie的代碼片段:

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 @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:

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 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,為什麼呢.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:

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 @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 db.posts.update({"id":artid}, {"$inc":{"views":1}})   # 並設置cookie response.COOKIES[artcookie] = True response.COOKIES[artcookie]['max-age'] = 500   TEMPLATE['posts'] = getArtList({"id":artid}) TEMPLATE.update(setTempVar())   return template('article.html', TEMPLATE)

　　這裡是可以正常獲取到cookie的,而且代碼沒有任何區別.唯一的區別就是用戶認證是跳轉了頁面.所以我help了一下:

　　?

1 2 from bottle import response help(response.set_cookie)

　　help的結果其中有兩個參數一個是path,和domain:

　　?

1 2 3 :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:

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 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定的cookie.
