Question

这是我的fisrt问题，所以我会尽力做到最好。

我正在尝试使用Soaplib 2.0在Python 2.6和Django 1.4中实现WebService服务器。

Web服务正在运行，Django正在Django开发服务器中提供服务。

以下是Django View和Urls的代码：

views.py

from soaplib.core.service import rpc, DefinitionBase, soap
from soaplib.core.model.primitive import String, Integer, Boolean
from soaplib.core.model.clazz import Array
from soaplib.core import Application
from soaplib.core.server.wsgi import Application as WSGIApplication
from django.http import HttpResponse

class HelloWorldService(DefinitionBase):
    @soap(String,Integer,_returns=Array(String))
    def say_smello(self,name,times):
        results = []
        for i in range(0,times):
            results.append('Hello, %s'%name)
        return results
    @soap(String,_returns=Boolean)
    def xml(self,xml):
        result = xml
        return True
    @soap(String,_returns=String)
    def xml2(self,xml2):
        return xml2



class DjangoSoapApp(WSGIApplication):
    csrf_exempt = True

    def __init__(self, services, tns):
        """Create Django view for given SOAP soaplib services and
tns"""

        return super(DjangoSoapApp,
            self).__init__(Application(services, tns))

    def __call__(self, request):
        django_response = HttpResponse()

        def start_response(status, headers):
            django_response.status_code = int(status.split(' ', 1)[0])
            for header, value in headers:
                django_response[header] = value

        response = super(DjangoSoapApp, self).__call__(request.META,
            start_response)
        django_response.content = '\n'.join(response)

        return django_response

my_soap_service = DjangoSoapApp([HelloWorldService], __name__)

urls.py

url(r'^soap/wsdl$', 'soap.views.my_soap_service'),
url(r'^soap/$', 'soap.views.my_soap_service'),

问题是，我想传递给WebService方法xml或xml2一个XML，并使用XML中的信息来处理。我收到错误。

如果我传递一个没有“＆amp;”等字符的简单字符串，一切正常，例如：

首先让我们导入suds并将suds设置为Debug：

from suds.client import Client
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)

现在让我们开始调用de WS：

WSDL = "http://server.test/soap/wsdl"
client = Client(WSDL)
client.service.xml('x and y')

工作完美，我得到“真实”，SUDS的日志显示我正在这样做：

DEBUG:suds.client:sending to (http://server.test/soap/wsdl)
message:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="soap.views" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <ns1:Body>
      <ns0:xml>
         <ns0:xml>x and y</ns0:xml>
      </ns0:xml>
   </ns1:Body>
</SOAP-ENV:Envelope>
DEBUG:suds.client:headers = {'SOAPAction': '"xml"', 'Content-Type': 'text/xml; charset=utf-8'}
DEBUG:suds.client:http succeeded:
<?xml version='1.0' encoding='utf-8'?>
<senv:Envelope xmlns:wsa="http://schemas.xmlsoap.org/ws/2003/03/addressing" xmlns:plink="http://schemas.xmlsoap.org/ws/2003/05/partner-link/" xmlns:xop="http://www.w3.org/2004/08/xop/include" xmlns:senc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s0="soap.views" xmlns:s12env="http://www.w3.org/2003/05/soap-envelope/" xmlns:s12enc="http://www.w3.org/2003/05/soap-encoding/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:senv="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"><senv:Body><s0:xmlResponse><s0:xml    Result>true</s0:xmlResult></s0:xmlResponse></senv:Body></senv:Envelope>
True

但如果我这样做：

client.service.xml('x &  y')

无效，它以suds超时结束，服务器报告管道损坏，这就是suds日志告诉我推送的内容：

DEBUG:suds.client:sending to (http://server.test/soap/wsdl)
message:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="soap.views" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <ns1:Body>
      <ns0:xml>
         <ns0:xml>x &amp;  y</ns0:xml>
      </ns0:xml>
   </ns1:Body>
</SOAP-ENV:Envelope>
DEBUG:suds.client:headers = {'SOAPAction': '"xml"', 'Content-Type': 'text/xml; charset=utf-8'}

这是suds上的错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/suds/client.py", line 542, in __call__

感谢此链接：http://grokbase.com/p/python/soap/125nhj9bdm/python-suds-xml-encoding-issue我发现是的，如果我发布WebService之类的话：

client.service.xml("x &amp;amp; y")

我说得对：

DEBUG:suds.client:sending to (http://server.test/soap/wsdl)
message:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="soap.views" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <ns1:Body>
      <ns0:xml>
         <ns0:xml>x &amp;amp; y</ns0:xml>
      </ns0:xml>
   </ns1:Body>
</SOAP-ENV:Envelope>
DEBUG:suds.client:headers = {'SOAPAction': '"xml"', 'Content-Type': 'text/xml; charset=utf-8'}
True

如果我使用方法xml2，那么我可以看到返回WebService的是：

client.service.xml2("x &amp;amp; y")

Suds的日志：

DEBUG:suds.client:sending to (http://server.test/soap/wsdl)
message:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="soap.views" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">

   <ns1:Body>
      <ns0:xml2>
         <ns0:xml2>x &amp;amp; y</ns0:xml2>

   </ns1:Body>
</SOAP-ENV:Envelope>
DEBUG:suds.client:headers = {'SOAPAction': '"xml2"', 'Content-Type': 'text/xml; charset=utf-8'}


DEBUG:suds.client:http succeeded:
<?xml version='1.0' encoding='utf-8'?>

x & y

但我不认为问题出在SUDS中，因为我使用这个版本的suds将XML推送到java WebServices，但我还没有找到这种soaplib的方法。

任何想法？这让我有点疯狂xD

我的最终目标是让Webservice与Soaplib一起使用Java中的SOAP客户端将XML推送到它。

由于

Answer 1

好的，解决了：D

我只能更改服务器端，因此我将代码迁移到spyne并像Charm一样工作。

https://github.com/arskom/spyne

我在网上发现了这个：

 Soaplib-2.0 was never released as a stable package, but the branch is still available

从soaplib他们去了Rpclib并从那里去了Spyne。

我确实发现了一个新的错误，这次是在suds上，但是我刚刚用于测试，但是如果我使用其他客户端，SoapUI或Java客户端，那就完美了。

使用PIP安装后，这是Django代码：

<强> urls.py

url(r'^testws/\?wsdl$', 'testmo.views.ws_test'),
url(r'^testws/$', 'testmo.views.ws_test'),

<强> views.py

from django.views.decorators.csrf import csrf_exempt
from spyne.server.django import DjangoApplication
from spyne.model.primitive import String
from spyne.service import ServiceBase
from spyne.interface.wsdl import Wsdl11
from spyne.protocol.soap import Soap11
from spyne.application import Application
from spyne.decorator import srpc



class ServiceWsTest(ServiceBase):
    @srpc(String, _returns=String)
    def testMethod(string):
        return string

ws_test = csrf_exempt(DjangoApplication(Application([ServiceWsTest],
    'http://example.com',
    in_protocol=Soap11(),
    out_protocol=Soap11(),
    interface=Wsdl11(),
)))

从现在开始，我将继续使用此库
