如何在spyne中实现元素的平面数组

Question

如何为Spyne编写处理SOAP请求的请求处理程序呢?

<getUsers>
  <users>
    <username>foo</username>
    <username>bar</username>
    ...
  </users>
</getUsers>

我已经试过了:

@rpc(Array(Unicode.customize(type_name='username'), min_occurs=1, nillable=False))
def getUsers(ctx, users):
    stuff

但是它产生的模式是这样的:

  <xs:complexType name="getUsers">
    <xs:sequence>
      <xs:element name="users" type="tns:stringArray"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="stringArray">
    <xs:sequence>
      <xs:element maxOccurs="unbounded" minOccurs="0" name="string" nillable="true" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>

如何将元素名称string更改为username ?最好也把stringArray变成更有意义的东西?我的方法完全错了吗?

Answer 1

2.10:

SomeArrayType = Array(Unicode, min_occurs=1, 
                               nillable=False, type_name='SomeArrayType')
SomeArrayType._type_info['username'] = SomeArrayType._type_info['string']
del SomeArrayType._type_info['string']
@rpc(SomeArrayType)
def some_call(ctx, some_array):
    # (...)

2.11:

from spyne import Mandatory as M
SomeArrayType = M(Array(Unicode, type_name='SomeArrayType',
                                                member_name='username'))
@rpc(SomeArrayType)
def some_call(ctx, some_array):
    # (...)

另外，如果需要数组非空，还需要在数组内使用Unicode(min_len=1, min_occurs=1, nillable=False)。例如:

SomeArrayType = M(Array(M(Unicode), type_name='SomeArrayType',
                                                member_name='username'))
