如何移除Spyne WebService响应中的<tns:objects>标签？

Absolutely! You can absolutely get rid of that <tns:objects> wrapper tag while keeping all other parts of your response structure intact in Spyne. Let me walk you through the exact fixes based on your current code setup:

Scenario 1: Your response uses a ComplexModel with an Array field #

If your current return structure wraps the array in a ComplexModel (like a response container), you just need to modify the Array definition to disable the wrapper tag.

Original Code (with <tns:objects> tag) #

from spyne import Application, rpc, ServiceBase, Integer, Unicode
from spyne.model.complex import ComplexModel, Array
from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication

class MyDataModel(ComplexModel):
    id = Integer
    name = Unicode

# This model generates the <tns:objects> wrapper
class MyApiResponse(ComplexModel):
    objects = Array(MyDataModel)

class MyWebService(ServiceBase):
    @rpc(_returns=MyApiResponse)
    def fetch_data(self):
        sample_data = [
            MyDataModel(id=1, name="Alice"),
            MyDataModel(id=2, name="Bob")
        ]
        return MyApiResponse(objects=sample_data)

# Initialize app
app = Application(
    [MyWebService],
    'com.yournamespace',
    in_protocol=Soap11(validator='lxml'),
    out_protocol=Soap11()
)
wsgi_app = WsgiApplication(app)

Fixed Code (without <tns:objects> tag) #

Just add the wrapper=None parameter to the Array field definition:

class MyApiResponse(ComplexModel):
    # Disable the wrapper tag entirely
    objects = Array(MyDataModel, wrapper=None)

This will make your response output the MyDataModel elements directly under the response root, with no <tns:objects> wrapping them.

Scenario 2: You're directly returning an Array from your service method #

If your service method returns an Array directly (without a wrapping ComplexModel), replace Array with Iterable or add wrapper=None to the Array definition.

Fixed Code Option 1: Use Iterable #

from spyne.model.complex import Iterable

class MyWebService(ServiceBase):
    # Use Iterable instead of Array to avoid the wrapper tag
    @rpc(_returns=Iterable(MyDataModel))
    def fetch_data(self):
        return [
            MyDataModel(id=1, name="Alice"),
            MyDataModel(id=2, name="Bob")
        ]

Fixed Code Option 2: Keep Array with wrapper=None #

class MyWebService(ServiceBase):
    # Add wrapper=None to the Array return type
    @rpc(_returns=Array(MyDataModel, wrapper=None))
    def fetch_data(self):
        return [
            MyDataModel(id=1, name="Alice"),
            MyDataModel(id=2, name="Bob")
        ]

Both options will produce a response with no <tns:objects> tag, while preserving all other elements and their structure.
