如何在Python中正确实例化WePay对象？

Question

我正在尝试获得一个访问令牌来代表用户做一些事情，我已经阅读了他们的文档并在他们的网站上遵循了这个(https://www.wepay.com/developer/create_accounts/oauth2)教程。

起初，我尝试直接使用带有URL中编码的参数的GET请求，但是我一直得到一个401，所以我尝试了他们的教程，现在控制台中出现了这个错误：

in add_merchant_token
    wepay = WePay(production, None)
TypeError: __init__() takes exactly 2 arguments (3 given)

我能够得到检索令牌的“代码”，但我无论如何也想不出如何获得实际的令牌。

代码：

code = request.args.get('code')
redirect_uri = "http://localhost:5000/add_merchant_token"

# application settings
client_id = XXXXXX
client_secret = 'XXXXXX'
production = False

wepay = WePay(production, None)

# create an account for a user
response = wepay.get_token(redirect_uri, client_id, client_secret, code)

# display the response
print response

return response

完整堆栈跟踪：

下面是一个关于如何使用第三方Python WePay SDK执行此操作的示例

from wepay import WePay
from wepay.exceptions import WePayHTTPError, WePayConnectionError

# application settings
CLIENT_ID = XXXXXX
CLIENT_SECRET = 'XXXXXX'
PRODUCTION = False
DEFAULT_SCOPE = "manage_accounts,collect_payments,view_user," \
                "preapprove_payments,manage_subscriptions,send_money"
wepay = WePay(production=PRODUCTION)

redirect_uri = "http://localhost:5000/add_merchant_token"
url = wepay.oauth2.authorize(CLIENT_ID, redirect_uri, DEFAULT_SCOPE, 
                             user_name="John Doe", user_email="john@example.com")
# send user to that `url` and then get code from the redirected url 
# query string. Note if 'error' is in a query, handle it appropriately
...
code = request.args.get('code')

# create an account for a user
try:
    response = wepay.oauth2.token(CLIENT_ID, redirect_uri, CLIENT_SECRET, code)
    access_token = response['access_token']
    # display the response
    print response
except WePayHTTPError as exc:
    if exc.error_code == 1012:
        print "code has expired"
    print exc
except WePayConnectionError as exc:
    print exc
    # problem with connecting to wepay, retry api call a bit later
