我想用正则表达式扩展 spyne Unicode 字段，以确保它是有效的电子邮件格式。但即使从 spyne 文档http://spyne.io/docs/2.10/manual/03_types.html复制粘贴基本示例，我在访问localhost/my-url-endpoint?wsdl.
我使用 Django 1.6 和 Spyne 2.10.10。在 Windows8 64 位上。任何建议为什么它失败？
编码：
from django.views.decorators.csrf import csrf_exempt
from spyne.protocol.soap import Soap11
from spyne.interface import Wsdl11
from spyne.service import ServiceBase
from spyne.decorator import srpc, rpc
from spyne.model.primitive import Unicode, Integer, Mandatory
from spyne.model.complex import Iterable
from spyne.application import Application
from spyne.server.django import DjangoApplication
class EmailString(Unicode):
__type_name__ = 'EmailString'
class Attributes(Unicode.Attributes):
max_length = 128
pattern = '[^@]+@[^@]+'
class MyService(ServiceBase):
@rpc(EmailString, _returns=Unicode)
def my_function(ctx, my_email):
return "Your email is %s" % my_email
application = Application(
[
MyService
],
tns="http://tempuri.org",
interface=Wsdl11(),
in_protocol=Soap11(validator='lxml'),
out_protocol=Soap11()
)
myServiceApp = csrf_exempt(DjangoApplication(application))
然后在 urls.py 中指向 MyServiceApp：
urlpatterns += patterns('',
(r'^my-url-endpoint$', 'myapp.views.myServiceApp'),
)
堆栈跟踪：
Internal Server Error: /en/wsCRMService

请帮忙。
