Question

servicem8 api（http://developer.servicem8.com/docs/platform-services/authentication/）具有参数范围作为oauth身份验证的一部分。虽然当我包含这个值时，我似乎得到了这个错误。

TypeError：prepare_request_uri（）为关键字参数＆＃39;范围＆＃39;

获取了多个值

# This information is obtained upon registration of a new GitHub OAuth
# application here: https://github.com/settings/applications/new
client_id = "ID"
client_secret = "SECRET"
authorization_base_url = 'https://www.servicem8.com/oauth/authorize'
token_url = 'https://www.servicem8.com/oauth/access_token'
grant_type = 'authorization_code'
scope = ['manage_inventory', 'manage_job_materials']
duration = 'permanent'
response_type = 'code'

@app.route("/")
def demo():
    redirect_uri = url_for('.callback', _external = True)
    state = str(uuid4())

    """Step 1: User Authorization.

    Redirect the user/resource owner to the OAuth provider (i.e. ServiceM8)
    using an URL with a few key OAuth parameters.
    """
    servicem8_client = OAuth2Session(client_id)
    authorization_url, state = servicem8_client.authorization_url(authorization_base_url, redirect_uri = redirect_uri, scope = scope)

    # State is used to prevent CSRF, keep this for later.
    session['oauth_state'] = state
    return redirect(authorization_url)

这是使用requests-oauthlib时包含额外参数的方式吗？有没有办法避免这种冲突？

通过将这些参数移动到构造函数而不是authorization_url方法来修复它。

    servicem8_client = OAuth2Session(client_id, redirect_uri = redirect_uri, scope = scope)
    authorization_url, state = servicem8_client.authorization_url(authorization_base_url, Response_type = response_type)
