Question

我正在尝试深入研究 SOAP 和 WSDL 概念。我正在使用 Python 的 spyne 库，并成功实现了 doc 中描述的 hello world 示例基本上，我有 server.py 和 client.py 文件，其中

server.py

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

现在，只是为了实验，我想通过 Postman 发送一个带有 XML 正文的请求（而不是使用像 suds.

这样的库

我通过 Postman 发送的正文如下所示：

<soapenv:Envelope xmlns:soapenv="schemas.xmlsoap.org/soap/envelope/" xmlns:tran="spyne.examples.hello.soap">
    <soapenv:Header/>
    <soapenv:Body>
        <tran:say_hello>
            <tran:name>ASD</tran:name>
            <tran:times>5</tran:times>
        </tran:say_hello>
    </soapenv:Body>
</soapenv:Envelope>

现在我收到以下错误消息：

<?xml version='1.0' encoding='UTF-8'?>
<soap11env:Envelope xmlns:soap11env="http://schemas.xmlsoap.org/soap/envelope/">
    <soap11env:Body>
        <soap11env:Fault>
            <faultcode>soap11env:Client.SoapError</faultcode>
            <faultstring>No {http://schemas.xmlsoap.org/soap/envelope/}Envelope element was found!</faultstring>
            <faultactor></faultactor>
        </soap11env:Fault>
    </soap11env:Body>
</soap11env:Envelope>

知道我做错了什么吗？

Answer 1

SOAP 命名空间错误。您的消息具有此命名空间：

<soapenv:Envelope xmlns:soapenv="schemas.xmlsoap.org/soap/envelope/" ...

错误消息中提到的 SOAP 信封的正确 SOAP 命名空间：

http://schemas.xmlsoap.org/soap/envelope/

像这样：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" ...
