rauth: JSON 对象必须是 str，而不是 'bytes'

Question

尝试在 Django 1.10 + Python 3 上实施 OAuth2 身份验证，我收到此错误：

rauth: the JSON object must be str, not 'bytes'

它发生在调用的线路上：session = sso.get_auth_session(data=data, decoder=json.loads)。

如果我删除 decoder=json.loads，我会收到以下错误：

Decoder failed to handle access_token with data as returned by provider. A different decoder may be needed.

这是我的方法：

def login(request):
    """
    Login view
    @author: Leonardo Pessoa
    @since: 11/06/2016
    """
    from rauth import OAuth2Service
    from django.conf import settings
    import json

    # instantiating our login service with environment defined settings
    sso = OAuth2Service(
        name                = settings.LOGIN_SETTINGS['name'],
        client_id           = settings.LOGIN_SETTINGS['client_id'],
        client_secret       = settings.LOGIN_SETTINGS['client_secret'],
        access_token_url    = settings.LOGIN_SETTINGS['access_token_url'],
        authorize_url       = settings.LOGIN_SETTINGS['authorize_url'],
        base_url            = settings.LOGIN_SETTINGS['base_url'],
    )

    # check if we have a login code returned by OAuth
    get_code = request.GET.get('code', '')
    if get_code == '':
        params = {
            'redirect_uri'    : settings.LOGIN_SETTINGS['redirect'],
            'response_type'   : 'code'
        }
        url = sso.get_authorize_url(**params)

        return redirect(url)
    else:
        # we are in!
        data = {'code'          : get_code,
                'grant_type'    : 'authorization_code',
                'redirect_uri'  : settings.LOGIN_SETTINGS['redirect']
                }

        session = sso.get_auth_session(data=data, decoder=json.loads)

        return redirect('/logado/')

第一次访问视图重定向到授权URL（没有GET['code']）。接下来，再次访问它（使用 GET['code']）以处理授权码和身份验证。

有什么想法吗？

我仍然认为应该有更直接的方法或错误修复，但这是我自己的解决方法：

def oauth_decode(data):
    import json

    new_data = data.decode("utf-8", "strict")

    return json.loads(new_data)
...
session = sso.get_auth_session(data=data, decoder=oauth_decode)

问题是 get_auth_session 默认情况下将响应中的字节流解码为 UTF-8。如果您指定一个新的解码器，您将覆盖它。所以我想我们在这里都需要 (UTF-8 + JSON).
