| 范文 | Python的Bottle框架中获取制定cookie的教程 这篇文章主要介绍了Python的Bottle框架中获取制定cookie的教程,主要是针对别的路径而不是当前页面的cookie,需要的朋友可以参考下 这两天为用bottle+mongodb写的一个项目加上登录功能,无奈怎么都获取不到保存的cookie,文档给出让我们这样操作cookie的代码片段: @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 虽然文档上没有但是还有一种操作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 但是无论我用哪种方式操作我都无法获取cookie,为什么呢.百思不得其解.但是我的一个处理文章点击率的提醒了我,代码如下: @route('/archrives/:aid#\d+#') def article_show(aid): db = dbconn.ConnDB() artid = int(aid) # 获取客户端ip remoteip = request.environ.get('REMOTE_ADDR') artcookie = remoteip+'ip'+aid print request.COOKIES.keys() # 判断cookie是否存在 if artcookie in request.COOKIES.keys(): # 存在则更新有效时间 response.COOKIES[artcookie] = True response.COOKIES[artcookie]['max-age'] = 500 else: # 不存在则更新文章查看次数 db.posts.update({"id":artid}, {"$inc":{"views":1}}) # 并设置cookie response.COOKIES[artcookie] = True response.COOKIES[artcookie]['max-age'] = 500 TEMPLATE['posts'] = getArtList({"id":artid}) TEMPLATE.update(setTempVar()) return template('article.html', TEMPLATE) 这里是可以正常获取到cookie的,而且代码没有任何区别.唯一的区别就是用户认证是跳转了页面.所以我help了一下: from bottle import response help(response.set_cookie) help的结果其中有两个参数一个是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) 明显bottle的cookie默认只在当前路径下能读取的到,所以要别的页面读取到cookie我们的代码须改成如下: 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'] 这样我们就能在别的路径下访问我们设定的cookie. |
