问题


A cookie associated with a cross-site resource at https://example.com/ was set without the SameSite attribute. It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with SameSite=None and Secure. You can review cookies in developer tools under Application>Storage>Cookies and see more details at https://www.chromestatus.com/feature/5088147346030592 and https://www.chromestatus.com/feature/5633521622188032.

Please let me know how to set the SameSite cookie attribute. Thanks in advance.

The way to set custom headers is to add the line below to your controller action:

response.headers['Set-Cookie'] = 'Secure;SameSite=None'.

Action dispatch cookies is responsible for writing cookies to browser set in application, this uses Rack::Utils.set_cookie_header!.

Support for SameSite has been added after rack version 1.6, you need to check your rack version in Gemfile and if it is < 1.6 you need to add the following code in config/initializers

require 'rack/utils'
module Rack
  module Utils
    def self.set_cookie_header!(header, key, value)
      case value
      when Hash
        domain  = "; domain="  + value[:domain] if value[:domain]
        path    = "; path="    + value[:path]   if value[:path]
        max_age = "; max-age=" + value[:max_age] if value[:max_age]
        expires = "; expires=" +
          rfc2822(value[:expires].clone.gmtime) if value[:expires]
        secure = "; secure"  if value[:secure]
        httponly = "; HttpOnly" if value[:httponly]
        same_site =
          case value[:same_site]
          when false, nil
            nil
          when :none, 'None', :None
            '; SameSite=None'
          when :lax, 'Lax', :Lax
            '; SameSite=Lax'
          when true, :strict, 'Strict', :Strict
            '; SameSite=Strict'
          else
            raise ArgumentError, "Invalid SameSite value: #{value[:same_site].inspect}"
          end
        value = value[:value]
      end
      value = [value] unless Array === value
      cookie = escape(key) + "=" +
        value.map { |v| escape v }.join("&") +
        "#{domain}#{path}#{max_age}#{expires}#{secure}#{httponly}#{same_site}"

      case header["Set-Cookie"]
      when nil, ''
        header["Set-Cookie"] = cookie
      when String
        header["Set-Cookie"] = [header["Set-Cookie"], cookie].join("\n")
      when Array
        header["Set-Cookie"] = (header["Set-Cookie"] + [cookie]).join("\n")
      end

      nil
    end
  end
end

Once done you can set SameSite attribute while creating a new cookie, for ex:

cookies['testing'] = {
  value: 'test',
  path: '/',
  expiry: 1.weeks.from_now,
  same_site: :none
}

you can also add the same_site: <value> to your session store as well.

Hope this helps!

In Rails 6.0 and 6.1 the same_site attribute has been added:

cookies["foo"] = {
  value: "bar",
  secure: Rails.application.config.secure_cookies,
  same_site: "None"
}

For Rails 5.x and lower, the rails_same_site_cookie gem is a good option for adding SameSite=None; to all your app's cookies. It uses middleware to do it.

A backport of fixes to rack was contributed here.

https://github.com/rack/rack/pull/1547

It won't be released, so you'll likely need to use a fork of rack in your Gemfile.

What I did is the following: In session_store.rb I configured:

MyApp::Application.config.session_store :cache_store, key: COOKIE_NAME, :expire_after => 1.days, :expires_in => 1.days, :domain => 'mydomain.com', same_site: :none

And I added this monkey patch:

require 'rack/utils'
module Rack
  module Utils
    def self.set_cookie_header!(header, key, value)
      case value
      when Hash
        domain  = "; domain="  + value[:domain] if value[:domain]
        path    = "; path="    + value[:path]   if value[:path]
        max_age = "; max-age=" + value[:max_age] if value[:max_age]
        expires = "; expires=" +
            rfc2822(value[:expires].clone.gmtime) if value[:expires]

        # Make it always secure, even in HTTP
        # secure = "; secure"  if value[:secure]
        secure = "; secure"

        httponly = "; HttpOnly" if value[:httponly]
        same_site =
            case value[:same_site]
            when false, nil
              nil
            when :none, 'None', :None
              '; SameSite=None'
            when :lax, 'Lax', :Lax
              '; SameSite=Lax'
            when true, :strict, 'Strict', :Strict
              '; SameSite=Strict'
            else
              raise ArgumentError, "Invalid SameSite value: #{value[:same_site].inspect}"
            end
        value = value[:value]
      end
      value = [value] unless Array === value
      cookie = escape(key) + "=" +
          value.map { |v| escape v }.join("&") +
          "#{domain}#{path}#{max_age}#{expires}#{secure}#{httponly}#{same_site}"

      case header["Set-Cookie"]
      when nil, ''
        header["Set-Cookie"] = cookie
      when String
        header["Set-Cookie"] = [header["Set-Cookie"], cookie].join("\n")
      when Array
        header["Set-Cookie"] = (header["Set-Cookie"] + [cookie]).join("\n")
      end

      nil
    end
  end
end
