Transform cURL command to Python Requests command

Question

I'm new with cURL and Requests and I have a doubt on how I can transform a cURL petition to a Requests command in Python.

Looking at Apache Stratos documentation Doc Page to perform a login against the server, in cURL you use:

curl -X GET -H "Content-Type: application/json" -k -v -u admin:admin https://localhost:9443/api/session

And it works on the terminal. Now, I want to do the same on my Django website and to transform the curl URL to python code and use the module "requests" I don't know how pass the user and pass info on the petition.

The code that I have now it's:

headers = {'Content-Type':'application/json'}
data = {}
req = requests.post('https://localhost:9443/api/session', headers=headers, params=data)

But I don't know how pass the user and password so I tried this (Requests Python Login Tutorial)

data = {"username":"admin","password":"admin"}

But I get a certificate error from server:

File "/usr/lib/python2.7/dist-packages/requests/adapters.py", line 385, in send raise SSLError(e)
requests.exceptions.SSLError: [Errno 1] _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

So, I'm sending correctly the user and password? How I can solve the certificate error?

Thanks and regards

You're on localhost. Is it absolutely critical to use SSL? Try http://localhost:9443/api/session . Python requests is actually very smooth dealing with SSL, but a valid SSL cert on localhost seems unlikely. — Juan Tomas

Yes, all URL's on the doc page uses Https and when you access to the login page on Firefox, you need to add a security exception to see the page. — MinionAttack

You can turn off SSL cert verification with the verify flag, and use basic authentication by specifying auth.

from requests.auth import HTTPBasicAuth

req = requests.post('https://localhost:9443/api/session', headers=headers, auth=HTTPBasicAuth('admin', 'admin'), verify=False)

See the requests docs for more info.

You are using your localhost which almost certainly doesn't have a valid certificate.

For testing purposes disable ssl verification (it is still encrypted just not verifying certificate)

req = requests.post('https://localhost:9443/api/session', headers=headers, params=data, verify=False)

After the @Sam solution and looking on the Requests Auth Doc Page I found the solution:

The Python Resquest code it's:

requests.get('https://localhost:9443/api/session', headers=headers, auth=HTTPBasicAuth('admin', 'admin'), verify=False)

The "params" field it's not needed.

And then:

u'{"Success":{ "sessionId": "547D78FD4966DDBE21AEFDAECE909DEC"}}'

Hope it helps someone!
