MissingSchema: Invalid URL

[spotopt]

Hi!
When I try to follow you example (https://github.com/wattsight/wapi-python/blob/master/examples/Timeseries_curve_examples/ts_simple_read.py), I get the following error:
MissingSchema: Invalid URL '/api/curves/get?name=tt+de+con+%C2%B0c+cet+min15+s': No schema supplied. Perhaps you meant http:///api/curves/get?name=tt+de+con+%C2%B0c+cet+min15+s?

I created a specific environment with conda to eliminate this as an error source:
conda create -n wapi python=3.6 anaconda
And the I run:
pip install -U wapi-python

This is my code:
import pandas as pd
import wapi
session = wapi.Session('config.ini')
start_date = pd.Timestamp('2018-6-1 00:00')
end_date = pd.Timestamp('2018-6-8 00:00')
curve_name = 'tt de con °c cet min15 s'
curve = session.get_curve(name=curve_name)

Any idea what is wrong? Thanks!

I tried the same code on a machine outside of the company network to check whether it is a proxy issue but I get the same error message.

Hi @RaikB,

I suspect you may be missing urlbase in your config file as seen here:
https://github.com/wattsight/wapi-python/blob/master/sampleconfig.ini

Let me know how it goes.
We also usually reply a bit faster on support@wattsight.com for future support questions.

This is the content of my config file without the secret parameters of course:
[common]
urlbase = https://api.wattsight.com
auth_type = OAuth
timeout = 300

[OAuth]
id =
secret =
auth_urlbase = https://auth.wattsight.com

So it must be something else. Anything else I could check?

What is interesting is that I get the following error if I switch from https in the base url to http:
MissingSchema: Invalid URL '/api/curves/get?name=tt+de+con+%C2%B0c+cet+min15+s': No schema supplied. Perhaps you meant http:///api/curves/get?name=tt+de+con+%C2%B0c+cet+min15+s?
So the recommended URL is adjusted based on what I define in the config file. Otherwise, I still get the same error.

Try removing the urlbase line entirely. We should have a default in place.

I still get this error:
MissingSchema: Invalid URL '/api/curves/get?name=tt+de+con+%C2%B0c+cet+min15+s': No schema supplied. Perhaps you meant http:///api/curves/get?name=tt+de+con+%C2%B0c+cet+min15+s?
However, I think I found the problem. In the code from above I used:
session = wapi.Session('config.ini')
The Session class interprets "config.ini" as the urlbase parameter because this is the first one in line. So all I need to fix this is:
session = wapi.Session(config_file='config.ini')
Quite obvious now.
Now I get this error:
SSLError: HTTPSConnectionPool(host='auth.wattsight.com', port=443): Max retries exceeded with url: /oauth2/token (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)')))
This might be a proxy problem. I will have a look.
@rune-bk: Thanks for the help so far.

Oh right I missed that. That makes sense.

Yea that looks very much like a proxy problem. You are missing an env.
See https://requests.readthedocs.io/en/master/user/advanced/#proxies on how to set it.
