我的相关wcf服务代码是：
<OperationContract()>
<WebGet(UriTemplate:="Authorize/{id}/{pw}", BodyStyle:=WebMessageBodyStyle.Wrapped, RequestFormat:=WebMessageFormat.Json, ResponseFormat:=WebMessageFormat.Json)>
Function Authorize(ByVal id As String, ByVal pw As String)
Function Authorize(ByVal id As String, ByVal pw As String) Implements IBasicServ.Authorize
Dim c As New List(Of Guid)
For i = 0 To 10
c.Add(Guid.NewGuid)
Next
Return c
End Function
python客户端中的代码是：
import requests
import json
def LoginAccess(userid, password):
response = requests.get('http://localhost:9624/BasicServ.svc/auth/test/')
print (response.json())
print('http://localhost:9624/BasicServ.svc/auth/Authorize/'+userid+'/'+password)
response = requests.get('http://localhost:9624/BasicServ.svc/auth/Authorize/'+userid+'/'+password,stream=False)
print (response.json())
第一个响应仅用于测试服务，它正在工作，第二个响应我收到错误。我会适当地编码加密和SSL，但目前正试图让其他客户端工作。我还测试了Stream = True和False，但结果是一样的。
我用Google搜索并发现错误通常与请求模块旧版有关，但我使用的是更新版。
请求模块是2.2.1 Python 3.3与Kivy WCF on .net 4

答案 0 :(得分：10)
您似乎对Python 3不熟悉。它引入了一种新的回溯方式，以便您可以最好地确定代码中的哪条路径，以便您可以找到最终异常的来源。让我们来看看你的追溯：
Traceback (most recent call last):
File "C:\Kivy180\Python33\lib\site-packages\requests-2.2.1-py3.3.egg\requests\packages\urllib3\connectionpool.py", line 313, in _make_request
httplib_response = conn.getresponse(buffering=True)
TypeError: getresponse() got an unexpected keyword argument 'buffering'
During handling of the above exception, another exception occurred:
重要这里是最后一行：“在处理上述异常时，发生了另一个异常：”。这表明TypeError: getresponse() got an unexpected keyword argument 'buffering'不是阻止您的程序的异常的来源，但实际上是在发生不同的异常时处理它。
您现在会注意到“在处理上述异常期间，发生了另一个异常：”在您粘贴的输出中多次出现，最终的跟踪结束于：
File "C:\Kivy180\Python33\lib\site-packages\requests-2.2.1-py3.3.egg\requests\adapters.py", line 378, in send
raise ConnectionError(e)
requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=9624): Max retries exceeded with url:
/BasicServ.svc/auth/Authorize/admin/1234
(Caused by <class 'ConnectionResetError'>:
[WinError 10054] An existing connection was forcibly closed by the remote host)
我已经将最后一行分解为更具可读性（因此它不会滚动到一边）。您看到的异常是由服务器强行关闭已打开的连接引起的。如果您使用Session对象，我通常希望看到这个，因为默认情况下会为您执行连接池，但是您每次都使用创建新Session对象的功能API。这意味着如果这种情况反复发生，这里的服务器很可能行为不端。服务器拒绝响应您的请求并强行关闭已建立的连接。在尝试阅读响应时，urllib3会收到WinError异常，除了提供自己的异常ConnectionResetError之外，没有其他方法可以恢复。请求然后抓住它并引发它自己的ConnectionError。
这里的问题似乎不是请求，而是一个行为不端的服务器。
另外，在网址中输入用户名和密码是非常糟糕的想法。我建议使用HTTP摘要式身份验证，HTTP基本身份验证或实现更安全的内容（如基于令牌的身份验证方案）进行调查。
