Question:
FIWARE Authentication in Python

Description:
I am trying to authenticate user using FIWARE. It returns a 404 when I request the token, but I don't have problems to get access code request.
My code:

class OAuth2(object):
def _init_(self):
self.client_id = "<client_id>"
self.client_secret = "<client_secret>"
self.site = 'http://0.0.0.0:8000'
self.redirect_uri = "http://192.168.99.101:8000/auth"
self.authorization_url = '/oauth2/authorize'
self.token_url = '/oauth2/token'

def authorize_url(self, **kwargs):
oauth_params =

oauth_params.update(kwargs)
return "%s%s?%s" % (self.site, quote(self.authorization_url), urlencode(oauth_params))

def get_token(self, code, **kwargs):
url = "%s%s" % (self.site, quote(self.token_url))
data =

data.update(kwargs)
response = requests.post(url, data=data)
content = response.content

if isinstance(response.content, str):
try:
content = json.loads(response.content)
except ValueError:
content = parse_qs(response.content)
else:
return content

In my app, I call authorize_url() to get the code.

@app.route("/authenticate")
def authenticate():
auth_url = auth_app.authorize_url()
return redirect(auth_url)

After, I get the code by callback url and I call the get_token() method:

@app.route('/auth', methods=['GET', 'POST'])
def auth():
error = request.args.get('error', '')
if error:
return "Error: " + error

code = request.args.get('code')
content = auth_app.get_token()
return render_template('index.html', content="content: " + content)
