Question

嗨如果找不到特定的Soap方法，如何处理suds中的异常。我的要求是如果找不到的方法（由用户输入）程序应该提示不是有效的方法。

 for method in client.wsdl.services[0].ports[0].methods.values():
     print "the existing methods in webservice are:" +method.name
     try:
        s=raw_input("enter the name of the method you want to scan: ")
        name= getattr(client.service,s)
     except suds.WebFault,e:
        print e

但如果我输错了方法，我的程序就会被终止。

你的程序应该是这样的：

for method in client.wsdl.services[0].ports[0].methods.values():
    print "the existing methods in webservice are:" +method.name
while True
    try:
        s=raw_input("enter the name of the method you want to scan: ")
        #if user enter exit or some special command, break here
        name= getattr(client.service,s)
        #call the target method here ...
    except suds.WebFault,e:
        print e

可以对第一个print行进行更多编辑，以使输出消息更具可读性，留给您。

您没有任何循环来让用户输入新数据。尝试类似：

methods = list(client.wsdl.services[0].ports[0].methods.values())
print "Existing methods are {0} and {1}.".format(", ".join(map(str, methods[:-1])), 
                                              str(methods[-1]))
while True:
    s = raw_input("Enter the name of the method you want to scan: ")
    if s not in methods:
        print "Not a valid method, please try again."
    else:
        break # valid method, continue
# rest of your code goes here

如果找不到方法，如何在python中使用suds处理Exception
