python - 类型错误 : set_cookie() got an unexpected keyword argument 'samesite' (flask)

Question

我尝试运行一些提供用户管理和身份验证/登录的 flask 扩展，例如 flask-admin。问题是，每当我尝试运行将运行一个简单的用户登录/注册页面然后单击登录或注册按钮的示例之一时，我总是会收到以下错误:

TypeError: set_cookie() got an unexpected keyword argument 'samesite'

完整的Python报错日志为:

Traceback (most recent call last):
  File "/usr/lib64/python2.7/site-packages/flask/app.py", line 2309, in __call__
    return self.wsgi_app(environ, start_response)
  File "/usr/lib64/python2.7/site-packages/flask/app.py", line 2295, in wsgi_app
    response = self.handle_exception(e)

    response = self.process_response(response)
  File "/usr/lib64/python2.7/site-packages/flask/app.py", line 2114, in process_response
    self.session_interface.save_session(self, ctx.session, response)
  File "/usr/lib64/python2.7/site-packages/flask/sessions.py", line 384, in save_session
    samesite=samesite

我环顾四周，但找不到任何解决方案。我使用的不同组件的版本是否不匹配？非常感谢任何帮助。

Answer 1

我升级到:

Flask>=1.0.2
Flask-Login==0.4.1
Werkzeug==0.14.1

错误消失了。我怀疑这是旧 Werkzeug 的问题
