Question

我试图创建一个非常基本的cherrypy webapp，它会在第一个（也是唯一的）页面加载之前询问用户的用户名和密码。我使用了CherryPy文档中提出的示例：http://cherrypy.readthedocs.org/en/latest/basics.html#authentication

这是我wsgi.py的具体代码：

import cherrypy
from cherrypy.lib import auth_basic
from myapp import myapp

USERS = {'jon': 'secret'}

def validate_password(username, password):
    if username in USERS and USERS[username] == password:
       return True
    return False

conf = {
    '/': {
       'tools.auth_basic.on': True,
       'tools.auth_basic.realm': 'localhost',
       'tools.auth_basic.checkpassword': validate_password
    }
}

if __name__ == '__main__':

    cherrypy.config.update({
        'server.socket_host': '127.0.0.1',
        'server.socket_port': 8080,
    })

    # Run the application using CherryPy's HTTP Web Server
    cherrypy.quickstart(myapp(), '/', conf)

上面的代码会给我一个浏览器用户/传递提示，但是当我点击确定提示时，我收到以下错误：

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/cherrypy/_cprequest.py", line 667, in respond
    self.hooks.run('before_handler')
  File "/usr/local/lib/python2.7/site-packages/cherrypy/_cprequest.py", line 114, in run
    raise exc
TypeError: validate_password() takes exactly 2 arguments (3 given)

我不确定它认为从哪里得到第三个参数。有什么想法吗？谢谢！

来自cherrypy的文档

   checkpassword: a callable which checks the authentication credentials.
        Its signature is checkpassword(realm, username, password). where
        username and password are the values obtained from the request's
        'authorization' header.  If authentication succeeds, checkpassword
        returns True, else it returns False.

因此，checkpassword的实现必须遵循相同的api：checkpassword(realm, username, password)，并且您向我们展示的内容缺少第一个参数 - 领域。
