开始尝试一下soap，用python访问

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),
)

http://github.com/jkp/soaplib/issues/#issue/2 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~~ ']
>>>
