开始尝试一下soap，用python访问wsdl服务

实验一下天气预报Webservice服务，数据来源于中国气象局：


http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

python的程序：如果需要库支持，下载地址：http://pypi.python.org/pypi?%3Aaction=index

推荐使用：setuptools，安装后可以使用easy_install很方便

安装fpconst：easy_install.py fpconst

SOAPpy 下载地址：http://pywebsvcs.sourceforge.net/

>>>from SOAPpy import WSDL

>>>wsdlFile = ‘http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl’

>>>server = WSDL.Proxy(wsdlFile)

>>>server.methods

--------------------------- V

{u'getWeatherbyCityNamePro': <SOAPpy.wstools.WSDLTools.SOAPCallInfo instance at 0x01168A58>, u'getSu

pportCity': <SOAPpy.wstools.WSDLTools.SOAPCallInfo instance at 0x011686E8>, u'getWeatherbyCityName':

<SOAPpy.wstools.WSDLTools.SOAPCallInfo instance at 0x01168940>, u'getSupportDataSet': <SOAPpy.wstoo

ls.WSDLTools.SOAPCallInfo instance at 0x01168828>, u'getSupportProvince': <SOAPpy.wstools.WSDLTools.

SOAPCallInfo instance at 0x01168760>}

---------------------------- A

>>> for a in server.getSupportProvince():

... for i in a:

... print i

------------------------------ V

---------------------------------------------- 用django搞个简单的soap服务：

>>>easy_install.py soaplib

>>>easy_install.py django

>>>django-admin.py startproject mysite

soaplib_handler.py

from soaplib.wsgi_soap import SimpleWSGISoapApp

from soaplib.service import soapmethod

from soaplib.serializers import primitive as soap_types

import StringIO

from django.http import HttpResponse

class DumbStringIO(StringIO.StringIO):

def read(self, n):

return self.getvalue()

class DjangoSoapApp(SimpleWSGISoapApp):

def __call__(self, request):

django_response = HttpResponse()

def start_response(status, headers):

status, reason = status.split(' ', 1)

django_response.status_code = int(status)

for header, value in headers:

django_response[header] = value

environ = request.META.copy()

body = ''.join(['%s=%s' % v for v in request.POST.items()])

environ['CONTENT_LENGTH'] = len(body)

environ['wsgi.input'] = DumbStringIO(body)

environ['wsgi.multithread'] = False

response = super(DjangoSoapApp, self).__call__(environ, start_response)

django_response.content = "/n".join(response)

return django_response

views.py

from django.http import HttpResponse

from soaplib_handler import DjangoSoapApp, soapmethod, soap_types

def hello(request):

return HttpResponse("Hello world")

class HelloWorldService(DjangoSoapApp):

__tns__ = 'http://localhost:8000/soap/'

@soapmethod(_returns=soap_types.Array(soap_types.String))

def say_hello(self):

results = []

results.append('Hello, Here is the first webservice test~~ ')

return results

hello_world_service = HelloWorldService()

urls.py --------------------

from django.conf.urls.defaults import *

from views import hello

from views import hello_world_service

urlpatterns = patterns('',

('^$', hello),

(r'^hello_world/', hello_world_service),

(r'^hello_world/service.wsdl', hello_world_service),

)

unicode错误补丁。

测试自己的soap服务：

>>> from SOAPpy import WSDL

>>> wsdl='http://127.0.0.1:8000/hello_world/service.wsdl'

>>> server = WSDL.Proxy(wsdl)

>>> server.methods

{u'say_hello': <SOAPpy.wstools.WSDLTools.SOAPCallInfo instance at 0x00E155F8>}

-----------------------A 竟然报错。。。贴一下别人提供的方法，但是实验了还是有问题。

OK, so mi fixes are simple.

Open serializers/primitive.py

and change line 445 to/

"%s:%s" % (self.serializer.get_namespace_id(), self.serializer.get_datatype=()))

and

soaplib/soap.py line 118 to

root, xmlids = ElementTree.XMLID(xml_string.encode()) and this makes by
services and WSDL files working both in SoapUI and standard PHP SOAP
without any problems

参考一下：http://hi.baidu.com/derris/blog/item/f68ad0de4c01a45a95ee371c.html

另一种本地测试没有问题：

>>> from soaplib.client import make_service_client

>>> from views import HelloWorldService

>>> client = make_service_client('http://127.0.0.1:8000/hello_world/',HelloWorldService())

>>> print client.say_hello()

['Hello, Here is the first webservice test~~ ']

>>>
