How to connect to protected WebService (Basic Authentication)

[madEng84]

Hi,
I want to connect to a protected webservice (BasicAuthentication)

What is the right approach?

I have tried this

from requests.auth import _basic_auth_str
from suds.client import Client
from suds.cache import NoCache

my_client = Client(WSDL_URL, 
                  location=WSDL_URL, 
                  cache=NoCache(), 
                  headers={'Authorization':_basic_auth_str(username,password)})

but without luck

Thank you in advance

I resolved it but i think that the problem is that it is not well documented...

from requests.auth import _basic_auth_str
from suds.client import Client
from suds.cache import NoCache
from suds.transport.https import HttpAuthenticated

my_client = Client(WSDL_URL, 
                  location=WSDL_URL, 
                  cache=NoCache(), 
                  transport={'Authorization':HttpAuthenticated(username='<username>',password='<password>')})

I have only a token header and I try with the following lines:

from requests.auth import _basic_auth_str
from suds.client import Client
from suds.cache import NoCache
from suds.transport.https import HttpAuthenticated
my_client = Client(WSDL_URL, 
                  location=WSDL_URL, 
                  cache=NoCache(), 
                  transport={'Authorization':HttpAuthenticated(Authorization='Bearer 10ac7b40-c252-3544-9b5e-301836e485a5')})

but I encountered a strange error

Traceback (most recent call last):
  File "test_ws2.py", line 18, in <module>
    transport={'Authorization':HttpAuthenticated(Authorization='Bearer 10ac7b40-c252-3544-9b5e-301836e485a5')})

@madEng84 have you any suggestion to call a webservice with an authorization token of this type: "Bearer Xxxx"

[madEng84]

@rmarzocchi84 I cannot find a similar solution to the one i used, but i see in this library code that "authorization" is a not expected key for HttpAuthenticated.init method. Maybe you have to write your own implementation.

Before it, try with an approach like this

Keep me informed

Looks like the HttpAuthenticated is not correctly initialized. I'm not sure if the following actually works, but maybe something like this might solve the problem?

my_client = Client(
    WSDL_URL, 
    location=WSDL_URL, 
    cache=NoCache(), 
    transport=HttpAuthenticated(
        headers={"Authorization" : "Bearer 10ac7b40-c252-3544-9b5e-301836e485a5"}
    ),
)

I have already tested this solution --> HTTP Error 405: Method Not Allowed

[rmarzocchi84]

Just dry-coding here, but would the following work

my_client = Client(
    WSDL_URL, 
    location=WSDL_URL, 
    cache=NoCache(), 
    transport=HttpAuthenticated(
        headers={"Authorization" : "Bearer 10ac7b40-c252-3544-9b5e-301836e485a5"}
    ),
)

I try it (removing cache=NoCache()).. and finally I encountered the
HTTP Error 405: Method Not Allowed like in this issue suds-community/suds#27
