python - xmlrpclib、wsapi4plone - 检查用户名和密码

Question

这是我的功能之一:

def connect():
    c = xmlrpclib.ServerProxy('http://username:password@host',
                allow_none=True,
            )
    return c

在返回c之前，如何检查此方法中的用户名和密码是否正确？

Answer 1

您可以使用此技巧检查提供的凭据是否有效(前提是 plone 站点已正确安装 wsapi4plone):

>>> server = xmlrpclib.ServerProxy("http://admin:admin@localhost:8080/plone")
>>> server.get_schema('Document')
{'creators': {'required': False, 'type': 'lines'}, 'description': ...
>>> baduser_server = xmlrpclib.ServerProxy("http://bad:bad@localhost:8080/plone")
>>> baduser_server.get_schema('Document')
Traceback (most recent call last):
...
ProtocolError: <ProtocolError for bad:bad@localhost:8080/plone: 401 Unauthorized>

所以对应的代码是:

from xmlrpclib import ServerProxy
from xmlrpclib import ProtocolError
try:
    server = ServerProxy("http://admin:admin@localhost:8080/plone")
    server.get_schema('Document')
    return server
except ProtocolError:
    return None
