在 PythonAnywhere 上使用 Flask-Stormpath 登录 Facebook 引发 JSONDecodeError

Question

我正在尝试在 PythonAnywhere 上部署我的应用程序，但我无法设置 Flask-Stormpath Facebook 登录。

基于电子邮件的登录和 Google 连接工作正常，但 Facebook 登录无效。我已将 Facebook 应用程序更新为正确的应用程序 url 并验证 Facebook connect 确实可以在本地主机上运行。

2016-04-14 18:08:07,121 :Exception on /facebook [GET]

    return self.scan_once(s, idx=_w(s, idx).end())
JSONDecodeError: Expecting value: line 1 column 1 (char 0)

这是我正在使用的 StormPath 配置：-

# Stormpath app configuration
app.config['STORMPATH_API_KEY_FILE'] = '/home/btpraasta/btp_raasta/stormpath/apiKey.properties'
app.config['STORMPATH_API_KEY_FILE'] = 'stormpath/apiKey.properties'
app.config['STORMPATH_APPLICATION'] = 'Raasta'
app.config['STORMPATH_REDIRECT_URL'] = '/redirecting'
app.config['STORMPATH_REGISTRATION_REDIRECT_URL'] = '/verifyEmail'
app.config['STORMPATH_REGISTRATION_TEMPLATE'] = 'register.html'
app.config['STORMPATH_LOGIN_TEMPLATE'] = 'login.html'
app.config['STORMPATH_FORGOT_PASSWORD_TEMPLATE'] = 'forgot.html'
app.config['STORMPATH_ENABLE_MIDDLE_NAME'] = False
app.config['STORMPATH_ENABLE_USERNAME'] = True
app.config['STORMPATH_REQUIRE_USERNAME'] = True
app.config['STORMPATH_ENABLE_FORGOT_PASSWORD'] = True
app.config['STORMPATH_ENABLE_FACEBOOK'] = True
app.config['STORMPATH_ENABLE_GOOGLE'] = True
app.config['STORMPATH_SOCIAL'] = {
    'FACEBOOK': {
        'app_id': 'xxxxx',
        'app_secret': 'xxxxx',
    },
    'GOOGLE': {
        'client_id': 'xxxxx',
        'client_secret': 'xxxxxx',
    }
}

client_id 和 client_secret 已被隐藏。相同的配置在本地主机上工作。

错误是由于 Facebook-SDK 版本 0.4 没有输出代理支持。提出了一个勾选，现在 Flask-Stormpath 使用支持相同的 Facebook-SDK 1.0 版。

如果您仍然遇到同样的问题，请更新您的 Flask-Stormpath :-

pip install --upgrade flask-stormpath
