Python- Suds.Client.Service问题,打印出标识符而不是方法文本
作者:互联网
嗨,我对Python和Web服务是相当陌生的,并且我已经开始尝试通过Python在WSDL中使用Web服务方法.现在,当我运行以下代码时,返回的值是“”.我的目标是获取GetMessage方法的返回值(一个简单的Hello World),而不是获取该方法的此标识符.有没有办法获得此返回值?
import logging
import sys
from suds.client import Client
sys.setrecursionlimit(2000)
url='http://localhost:50774/HostDevServer/HelloWorldService.svc?wsdl'
client = Client(url)
example = client.service.GetMessage
print example
我也尝试了以下代码
import logging
import sys
from suds.client import Client
sys.setrecursionlimit(2000)
url='http://localhost:50774/HostDevServer/HelloWorldService.svc?wsdl'
client = Client(url)
example = client.service.GetMessage()
print example
并返回以下错误消息:
No handlers could be found for logger "suds.client"
Traceback (most recent call last):
File "C:\Python27\exampleForSuds.py", line 7, in <module>
example = client.service.GetMessage()
File "build\bdist.win32\egg\suds\client.py", line 542, in __call__
return client.invoke(args, kwargs)
File "build\bdist.win32\egg\suds\client.py", line 602, in invoke
result = self.send(soapenv)
File "build\bdist.win32\egg\suds\client.py", line 649, in send
result = self.failed(binding, e)
File "build\bdist.win32\egg\suds\client.py", line 708, in failed
raise Exception((status, reason))
Exception: (415, u'Unsupported Media Type')
我可以通过添加以下内容来解决第一个没有处理程序的错误:
logging.getLogger('suds.client').setLevel(logging.CRITICAL)
但是错误消息的其余部分将保留.有什么我想念的吗?我已经搜索了几个小时,实际上找不到任何显示类似问题的东西.
更新:
这是在第一个代码段中输出的内容:
<suds.client.Method instance at 0x02D9FC38>
我尝试了塞巴斯蒂安的想法,得到的是以下几点:
Traceback (most recent call last):
File "C:\Python27\exampleForSuds.py", line 10, in <module>
example = client.service.GetMessage()
File "build\bdist.win32\egg\suds\client.py", line 542, in __call__
return client.invoke(args, kwargs)
File "build\bdist.win32\egg\suds\client.py", line 602, in invoke
result = self.send(soapenv)
File "build\bdist.win32\egg\suds\client.py", line 649, in send
result = self.failed(binding, e)
File "build\bdist.win32\egg\suds\client.py", line 708, in failed
raise Exception((status, reason))
Exception: (400, u'Bad Request')
塞巴斯蒂安的想法的客户价值如下:

此错误的代码也是如此:
import logging
import sys
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.transport.http').setLevel(logging.DEBUG)
from suds.client import Client
sys.setrecursionlimit(2000)
url='http://localhost:50774/HostDevServer/HelloWorldService.svc?wsdl'
headers = {'Content-Type': 'application/soap+xml; charset="UTF-8"'}
client = Client(url,headers=headers)
print client
example = client.service.GetMessage()
print example
最终更新:
找到解决问题的方法,结果发现该问题与python代码无关,但与Web服务的web.config无关.它需要利用basicHttpBinding
解决方法:
要解决“不支持的媒体类型”错误,您可以指定服务器支持的类型,例如:
headers = {'Content-Type': 'application/soap+xml; charset="UTF-8"'}
client = Client(wsdl_url, headers=headers)
要查看肥皂水实际发送的内容,可以配置日志记录:
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.transport.http').setLevel(logging.DEBUG)
