allow_none在扭曲的XML-RPC服务器

Question

我建立xml rpc服务使用扭曲，我想使用None，就像它可以在标准的Python库中完成。如何将allow_none传递给xmlrpc服务器的扭曲版本？

Answer 1

XMLRPC接受allowNone作为其初始值设定项的参数。因此，如果您想支持None，请在实例化资源时通过True。

from twisted.web.xmlrpc import XMLRPC 
resource = XMLRPC(allowNone=True) 

Answer 2

我觉得应该在客户端指定...

当您创建从你的XML-RPC客户端代理 - 您可以通过关键字参数AL​​LOW_NONE = True以蟒蛇的xmlrpclib模块像下面...

In [184]: import xmlrpclib as rpc 

In [185]: sock = rpc.ServerProxy('http://localhost/xmlrpc/object',allow_none=True) 

编辑：

from twisted.web.xmlrpc import Proxy 
proxy = Proxy('http://localhost/xmlrpc', allowNone=True)
