Unexpected keyword argument "buffering" - python client

I get the error: "getresponse () received an unexpected keyword argument 'buffering'". Complete error log:

My wcf related service code:

<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

Code in python client:

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())

The first answer is just for testing the service and it works, the second is I get an error. I would code appropriately for encryption and SSL, but am currently trying to get this client to rest. I also tested with Stream = True and False but the result is the same.

I searched for it and found that the error is usually due to the request module being old, but I'm using the updated one.

It looks like you are not familiar with Python 3. It introduced a new style of tracing so you can better understand which path was taken through your code so that you can find the source of the final exception. Let's take a look at your trace:

 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:

the important thing is the last line: "While handling the above exception, another exception occurred:". This means it was TypeError: getresponse() got an unexpected keyword argument 'buffering'

not the source of the exception that stopped your program, but in fact it was being handled when another exception was thrown.

Now you will notice that "while handling the above exception, another exception occurred:" occurs a few more times in the output you drew, and the final trace ends with:

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)


I have stripped this last line so it can be read (so it doesn't scroll to the side). The exception you are seeing is caused by the server forcibly closing the open connection. I usually expect to see this if you are using an object Session

, because the default is connection pooling, but you are using a functional API that creates a new object every time Session

. This means that the server is most likely mistaken here if it happens repeatedly. The server refuses to respond to your request and forcibly close the connection that was made. When trying to read the response urllib3 gets an exception WinError

, from which there is no good way to recover other than giving it its own exceptionConnectionResetError

... Queries then grab it and bring it up of its own ConnectionError

.

The problem here is not the request, but the wrong server instead.

On the other hand, having a username and password in a URL is a very bad idea . I would suggest investigating using HTTP Digest Authentication, HTTP Basic Authentication, or implementing something more secure (like a token based authentication scheme).
