Python泡沫 - 未在服务中定义的方法

我试图使用suds连接到本地网络上的KnowledgeTree Web服务。我可以创建客户端并检索服务信息，但调用login方法列出的产生suds.WebFault: Server raised fault: 'method "login" not defined in service'。Python泡沫 - 未在服务中定义的方法

（注：我不得不使用ImportDoctor解决创建客户端时，一个命名空间的问题我不知道，如果目前的问题可能是相关的。）

是否存在与方式有问题我设置客户端还是发送命令，或者是服务器端的问题？如有必要，我可以更改生成WSDL的服务器上的代码，但我不知道此时需要纠正哪些问题。

设置客户端：

import logging 
from suds.client import Client 
from suds.xsd.doctor import ImportDoctor, Import 
import getpass 

logging.basicConfig(level=logging.INFO) 
logging.getLogger('suds.client').setLevel(logging.DEBUG) 
url='http://192.168.1.213/knowledgetree/ktwebservice/webservice.php?wsdl' 
imp = Import('http://schemas.xmlsoap.org/soap/encoding/') 
imp.filter.add('urn:KnowledgeTree') 
d = ImportDoctor(imp) 
client = Client(url, doctor=d) 

print(client) 
response = client.service.login(getpass.getuser(), getpass.getpass(), '192.168.1.42')

的print(client)结果：

啊还有一个不好的WSDL。 – jathanism 2011-05-17 14:45:56

我试图找出零进展。如果其他人遇到同样的问题，我的建议是为自己节省麻烦并使用REST代替。 – 2011-05-20 19:08:07

我认为这是可靠的建议。当WSDL没有正确引用方法时，SOAP可能会是一个巨大的痛苦。另一方面，REST依靠消费者来做正确的事情。 – jathanism 2011-05-25 22:30:40

有没有可能发布工作信封的例子？你的代码为我生成了同样的'suds.WebFault'，但是如果我能确定究竟需要修复什么，这绝对是一个正确的方向。 – 2011-10-07 16:06:48

不幸的是，我们KT安装工作中的肥皂接口似乎损坏了，所以现在无法进行测试。当它再次工作时会回来。 – 2011-10-13 06:14:05
