早上好，我正在尝试在 Otree 中使用 Google 验证码，我安装了 recaptcha 并创建了一个给我密钥的帐户，但是当我运行 powershell 时它显示以下错误：


Traceback (most recent call last):
  File "c:\users\user\appdata\local\programs\python\python37\lib\site-packages\otree_startup\__init__.py", line 202, in do_django_setup

django.core.exceptions.ImproperlyConfigured: ('Setting RECAPTCHA_PUBLIC_KEY is not of type', <class 'str'>)

这是我设置中的代码，enviroment.get 代码用于在 Heroku 上运行实验。

RECAPTCHA_PUBLIC_KEY = 'RECAPTCHA_PUBLIC_KEY'

RECAPTCHA_PRIVATE_KEY = 'RECAPTCHA_PUBLIC_KEY'

RECAPTCHA_PUBLIC_KEY = environ.get('RECAPTCHA_PUBLIC_KEY')

RECAPTCHA_PRIVATE_KEY = environ.get('RECAPTCHA_PRIVATE_KEY')

关键是数字，我不知道如何使验证码有效，有人可以提供一个想法吗？？

【解决方案1】：

我在那个模块上遇到了同样的问题，我所做的是：

在settings.py 中用str() 包装密钥：

RECAPTCHA_PUBLIC_KEY = str('YOUR_RECAPTCHA_PUBLIC_KEY')
RECAPTCHA_PRIVATE_KEY = str('YOUR_RECAPTCHA_PRIVATE_KEY')

我通过将调试打印直接插入site-packages\captcha\__init__.py 来检查它，如下所示：

SETTINGS_TYPES = {
    "RECAPTCHA_DOMAIN": str,
    "RECAPTCHA_PRIVATE_KEY": str,
    "RECAPTCHA_PROXY": dict,
    "RECAPTCHA_PUBLIC_KEY": str,
    "RECAPTCHA_VERIFY_REQUEST_TIMEOUT": int,
}

print(settings.RECAPTCHA_PRIVATE_KEY) # <--added
print(type(settings.RECAPTCHA_PRIVATE_KEY)) # <--added

# Validate settings types.
for variable, instance_type in SETTINGS_TYPES.items():
    if hasattr(settings, variable) \
            and not isinstance(getattr(settings, variable), instance_type):
        raise ImproperlyConfigured(
            "Setting %s is not of type" % variable, instance_type
        )

然后我输入python manage.py shell 来查看输出。实际上，RECAPTCHA_PRIVATE_KEY 的类型是 unicode 而不是 str。
