@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.
