Hi, Dieter:
Thanks for your replay.
1:By the url "
http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl" , we can
get the words :
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/"xmlns:soapenc="
http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="
http://schemas.xmlsoap.org/wsdl/mime/" xmlns:tns="http://WebXml.com.cn/"
xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soap12=*"
http://schemas.xmlsoap.org/wsdl/soap12/*"xmlns:http="
http://schemas.xmlsoap.org/wsdl/http/" xmlns:wsdl="
http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://WebXml.com.cn/">
<wsdl:documentation xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
Maybe it's the fault of soap1.2
2: I once did a webservice server-side using suds. Most of time, they work
together well. While, sometimes, suds returns some message like the
exception mentioned above.
If idle, wish you have a look and give me some points. Thanks in advance.
#NOTE: the code can also be found in "
http://soaplib.github.com/soaplib/2_0/pages/helloworld.html"
# soaplib_server.py
import soaplib
from soaplib.core.service import soap
from soaplib.core.service import rpc, DefinitionBase
from soaplib.core.model.primitive import String, Integer
from soaplib.core.server import wsgi
from soaplib.core.model.clazz import Array
from soaplib.core import Application
class HelloWorldService(DefinitionBase):
@soap(String,Integer,_returns=Array(String))
def say_hello(self,name,times):
results = []
for i in range(0,times):
results.append('Hello, %s'%name)
return results
if __name__=='__main__':
print 'server begin running...'
try:
from wsgiref.simple_server import make_server
soap_application = Application([HelloWorldService], 'tns')
wsgi_application = wsgi.Application(soap_application)
server = make_server('localhost', 7789, wsgi_application)
server.serve_forever()
except ImportError:
print "Error: example server code requires Python >= 2.5"
# suds.py
import suds
def test_soaplib():
url = "http://localhost:7789/?wsdl"
client = suds.client.Client(url,cache=None)
print 'client', client
output = client.service.say_hello('jia',3)
print 'output', output
when you invoke sus.py , it takes much time and a long time later returns
the right result
”output (stringArray){
string[] =
"Hello, jia",
"Hello, jia",
"Hello, jia",
}
“
Sometimes, it returns exceptions as follows. most of time it return the
result successfully after 2 or 3 minutes

# okay, the problem is why sometimes the client return the exception and
most of time return the correct results some minutes later?
Thanks for your spirit and time.
