如何为Rails Session设置SameSite为Lax？Rails 6.0.3.1原生设置咨询

Great questions! Let's tackle them step by step:

Since you're working with Rails 6.0.3.1, here are the native, straightforward ways to set this up:

单独配置Session Cookie #

Open config/initializers/session_store.rb and update your session store config to include the same_site option:

Rails.application.config.session_store :cookie_store,
  key: '_your_app_session_name',
  same_site: :lax

全局设置所有Cookie的SameSite规则（包含Session） #

If you want all cookies in your app to default to SameSite=Lax, add this line to config/application.rb:

config.action_dispatch.cookies_same_site_protection = :lax

You can also adjust this per environment for better security. For example, in config/environments/production.rb, you might switch to :strict for tighter security controls:

Rails.application.configure do
  # ... other production environment configs
  config.action_dispatch.cookies_same_site_protection = :strict
end

Absolutely! Rails 6.0 introduced native support for configuring the SameSite attribute on cookies—including session cookies—directly in the framework. You don't need any third-party gems like secure_headers to handle this.

This feature was added to align with modern browser security standards, and it’s fully baked into Rails 6.0.3.1, so you can rely on the built-in configuration options without extra dependencies.
