python - 无法使用以字符串形式存在的方法名（来自 web 服务）。我尝试使用 getattr，但随后无法将其扩展为 suds

Question

from suds.client import Client #@UnresolvedImport
from suds.transport.https import HttpAuthenticated #@UnresolvedImport
import urllib2

class methodinvokeclass():
    def methodinvokemethod(self,*args):

        method=args[1]
        c=args[2]
        print c
        response=c.service.method("90210")# I know this wont work,coz of method, but even I cant get me way thru with getattr
        #response=c.service.LatLonListZipCode("90210")

        print response

if __name__=="__main__":

        invokemethodname="LatLonListZipCode"#Webservice name which I want to invoke...later !

        f=open("C:\wsdllocation.txt",'r')# picks up the WSDL file location from the above file
        webservwsdl=f.readline()
        f.close()
        y=methodinvokeclass()#dummy object
        z=methodinvokeclass()#dummy object

        t = HttpAuthenticated(username='x', password='x')#helps me getting thru my corporate firewall
        t.handler = urllib2.HTTPBasicAuthHandler(t.pm)#helps me getting thru my corporate firewall
        t.urlopener = urllib2.build_opener(t.handler)#helps me getting thru my corporate firewall
        c = Client(url=webservwsdl,transport=t)#SUDs client !!!!!

        x=y.methodinvokemethod(z,invokemethodname,c)# invoking the code above

您可以使用getattr从服务中检索 SOAP 方法。改用这个：

impl = getattr(c.service, method)
response = impl('90210')
print response

这是一个使用webservicex 测试 SOAP 服务的工作示例：

url = 'http://www.webservicex.net/stockquote.asmx?WSDL'
client = Client(url=url)
name = 'GetQuote'
impl = getattr(client.service, name)
print impl('IBM')
