如何从Rails控制台生成CSRF令牌？

我正在尝试进行经过身份验证的帖子请求,我需要CSRF.当我登录时,_csrf_token由于某种原因它不会生成:

2.0.0p247 :126 >   app.post '/community_members/login', {"refinery_user[login]"=>'chloe', 'refinery_user[password]'=>'test'}
 => 302
2.0.0p247 :127 > app.session
 => {"warden.user.refinery_user.key"=>[[56], "$2a$10$gr/rTcQfuXnes1Zml3qOPu"], "session_id"=>"f77d89cef9ff1710890f575b479bb690"}

我app.session[:_csrf_token] ||= SecureRandom.base64(32)在登录前尝试过,但总是被删除.我还尝试先获取登录表单,但_csrf_token仍未设置.

2.0.0p247 :133 >   app.get '/community_members/sign_in'
2.0.0p247 :134 > app.response # authenticity_token is burried in the raw HTML
2.0.0p247 :136 >   app.post '/community_members/login', {"refinery_user[login]"=>'chloe', 'refinery_user[password]'=>'test'}
2.0.0p247 :137 > app.session
 => {"warden.user.refinery_user.key"=>[[56], "$2a$10$gr/rTcQfuXnes1Zml3qOPu"], "session_id"=>"c2c564229e55b81ca788788558d7d11a"}

如何手动生成令牌以传递给帖子请求？

哦,好吧,我想我需要在登录表单中提交authenticity_token(在获取登录表单后在会话中设置),然后将其永久地放入会话中!这有效:

app.post '/ community_members /登录',{ 'authenticity_token'=> 'GfT5GtcUmYQ927oNQmh2MR0NKQucGSx8mtMg3Ph9kXw =' "refinery_user [登录]"=> '批发', 'refinery_user [口令]'=> '测试'}
