Question

我想用regex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时也会收到上述错误（请参阅标题）。

我使用Django 1.6和Spyne 2.10.10。在Windows8 64位上。有什么建议失败吗？

代码：

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'),
)

堆栈追踪：

请帮忙。

Answer 1

如果您这样做，它将起作用：

EmailString = Unicode(128, pattern='[^@]+@[^@]+', type_name="EmailStringType")

这种模式只是一个例子，你可以在那里找到更好的模式。

Answer 2

经过数小时的研究后，我发现如果你这样做也会有效 class EmailString(Unicode(pattern='[^@]+@[^@]+')): __namespace__ = 'tempuri.org' __type_name__ = 'EmailString'

看起来像元类的EmailString的属性不应该被覆盖然后它的工作原理。相反，您必须将自定义放在扩展类的构造函数中（在本例中为Unicode）

属性'type'：QName值'{http://www.w3.org/2001/XMLSchema}EmailString'未解析为（n）类型定义。，第4行
