- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在尝试使用 suds
连接到本地网络上的 KnowledgeTree
网络服务。我可以创建客户端并检索服务信息,但是调用那里列出的 login
方法会产生 suds.WebFault: Server raised fault: 'method "login"not defined in service'
。
(注意:我在创建客户端时不得不使用 ImportDoctor 来解决命名空间问题。我不知道是否与当前问题有关。)
是我设置客户端或发送命令的方式有问题,还是服务器端有问题?如有必要,我可以更改生成 WSDL 的服务器上的代码,但此时我不知道需要更正哪些内容。
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')
print(client)
的结果:
