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.

The traceback indicates a bad reply from the remote web server:
the response in not a valid HTTP response.

This does not look like a client problem
(at least not completely a client problem).

Should the problem be reproducible, then the most likely cause would be
some error in the WSDL (bad port information) which causes the client
to speak to a non HTTP server.

WSDL is complexe. Especially, it allows to specify different sets of
ports. If the concrete WSDL uses multiple ports, clients may
choose different ports unless the port is specified explicitely in
the call. Maybe, "suds" is using a broken port definition while other
clients use another correct port definition.


Note also that "suds" does not (yet) support "SOAP 1.2" (unlike
the Java/.Net soap clients). Check whether your WSDL defines
a "SOAP 1.1" port and in this case, use this one.
