is there a difference between curl -u and python requests

Question

So there's a web page that I want to retreive with python.Requests

https://ororo.tv/api/v2/episodes/9

which requires basic authentication. If I do it with curl like this

 curl -u [email protected]:password https://ororo.tv/api/v2/episodes/9

I get the response I want, however, when trying to do the same in python with Requests library, like this

>>> r = requests.get('https://ororo.tv/api/v2/episodes/9', auth=('[email protected]', 'password'))
>>> r
<Response [520]>

I always get 520 response. Could someone tell me, what i could be doing wrong ?

Answer 1

Yes, there are subtle differences. There are slight differences in the headers being sent, and those apparently matter to this API.

If you change the URL queried to use http://httpbin.org/get (an end-point of the online HTTP test service HTTPBin.org, you can see the differences in what curl and requests send:

$ curl -u [email protected]:password http://httpbin.org/get
{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
    "Host": "httpbin.org",
    "User-Agent": "curl/7.51.0"
  },
  "origin": "84.92.98.170",
  "url": "http://httpbin.org/get"
}
$ python -c "import requests; print(requests.get('http://httpbin.org/get', auth=('[email protected]', 'password')).text)"
{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Accept-Encoding": "gzip, deflate",
    "Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
    "Host": "httpbin.org",
    "User-Agent": "python-requests/2.11.1"
  },
  "origin": "84.92.98.170",
  "url": "http://httpbin.org/get"
}

To highlight the differences:

• requests sends one extra header, Accept-Encoding, set to gzip, deflate
• The User-Agent header differs; both reflect the current agent.

You'd have to see which one of these headers causes the issue on the https://ororo.tv/api/v2 site. When I correct the URL to use v2 and https, like the curl command, and set the User-Agent header then I get a valid response:

>>> headers = {'User-Agent': 'curl/7.51.0'}
>>> r = requests.get('https://ororo.tv/api/v1/episodes/9',
                     auth=('[email protected]', 'password'), headers=headers)
>>> r
<Response [200]>
>>> from pprint import pprint
>>> pprint(r.json())
