【问题描述】：

我想创建一个使用 Django 的服务器，并将响应作为 SOAP 进行响应，因此出于这个原因我尝试使用 spyne，但我无法运行给定的代码

class HelloWorldService(ServiceBase):
    @rpc(Unicode, Integer, _returns=Iterable(Unicode))
    def say_hello(ctx, name, times):
        \"\"\"Docstrings for service methods appear as documentation in the wsdl.
        <b>What fun!</b>
        @param name the name to say hello to
        @param times the number of times to say hello
        @return the completed array
        \"\"\"

        for i in range(times):
            yield u\'Hello, %s\' % name


application = Application([HelloWorldService], \'spyne.examples.hello.soap\',
                          in_protocol=Soap11(validator=\'lxml\'),
                          out_protocol=Soap11())

wsgi_application = WsgiApplication(application)


if __name__ == \'__main__\':
    import logging

    from wsgiref.simple_server import make_server

    logging.basicConfig(level=logging.DEBUG)
    logging.getLogger(\'spyne.protocol.xml\').setLevel(logging.DEBUG)

    logging.info(\"listening to http://127.0.0.1:8000\")
    logging.info(\"wsdl is at: http://localhost:8000/?wsdl\")

    server = make_server(\'127.0.0.1\', 8000, wsgi_application)
    server.serve_forever()

【解决方案1】：

删除 in_protocol 中的 validator='lxml' 选项

不知道是什么原因，验证器响应时间长或者没有工作。

并添加导入语句

from spyne import Application, rpc, ServiceBase, Iterable, Integer, Unicode

from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication

class HelloWorldService(ServiceBase):
    @rpc(Unicode, Integer, _returns=Iterable(Unicode))
    def say_hello(ctx, name, times):
        """Docstrings for service methods appear as documentation in the wsdl.
        <b>What fun!</b>
        @param name the name to say hello to
        @param times the number of times to say hello
        @return the completed array
        """

        for i in range(times):
            yield u'Hello, %s' % name


application = Application([HelloWorldService], 'spyne.examples.hello.soap',
                in_protocol=Soap11(),
                out_protocol=Soap11())

wsgi_application = WsgiApplication(application)

if __name__ == '__main__':
    import logging

    from wsgiref.simple_server import make_server

    logging.basicConfig(level=logging.DEBUG)
    logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)

    logging.info("listening to http://127.0.0.1:8000")
    logging.info("wsdl is at: http://localhost:8000/?wsdl")

    server = make_server('127.0.0.1', 8000, wsgi_application)
    server.serve_forever()

这是我的 Postman 和 curl 测试结果

POST表扬正文

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <say_hello xmlns="spyne.examples.hello.soap">
        <name>Tom Cruise</name>
        <times>3</times>
    </say_hello>
  </soap:Body>
</soap:Envelope>

用于终端管道的带有 XMLlint 的 curl POST 命令

$ curl --location --request POST 'http://localhost:8000' --header 'Content-Type: text/xml; charset=utf-8' --header 'SOAPAction: say_hello' --data-raw '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <say_hello xmlns="spyne.examples.hello.soap">
        <name>Tom Cruise</name>
        <times>3</times>
    </say_hello>
  </soap:Body>
</soap:Envelope>
' | xmllint --format -

    <tns:say_helloResponse>
      <tns:say_helloResult>
        <tns:string>Hello, Tom Cruise</tns:string>
        <tns:string>Hello, Tom Cruise</tns:string>
        <tns:string>Hello, Tom Cruise</tns:string>
      </tns:say_helloResult>
    </tns:say_helloResponse>
  </soap11env:Body>
</soap11env:Envelope>

还有我的python版本和spyne版本

$ python --version
Python 3.10.4

$ pip show spyne
Name: spyne
Version: 2.14.0
