我试图在以下GitHub问题中实现@hassox提供的建议:
https://github.com/ueberauth/guardian/issues/142
用户登录后,我生成一个令牌并将其存储在一个包含ttl的cookie中:
claims = Guardian.Claims.app_claims
|> Guardian.Claims.ttl({30, :days})
{:ok, token, full_claims } = Guardian.encode_and_sign(user, :remember, claims)
thirty_days = 86400 * 30
conn = put_resp_cookie(conn, "remember_me", token, max_age: thirty_days )
另外,我的Guardian.Plug.LoadResource
管道中有一个插件(放在:browser_auth
下面):
pipeline :browser_auth do
plug Guardian.Plug.VerifySession
plug Guardian.Plug.LoadResource
plug Zoinks.Plug.RememberMe
end
这就是插件目前的样子:
defmodule Zoinks.Plug.RememberMe do
import Plug.Conn
import Guardian.Plug
def init(opts \\ %{}), do: Enum.into(opts, %{})
def call(conn, opts) do
current_user = current_resource(conn)
if ( current_user == nil ) do
jwt = conn.req_cookies["remember_me"]
case Guardian.decode_and_verify(jwt) do
{ :ok, claims } ->
if ( claims |> Map.get("typ") == "remember" ) do
{:ok, remember_user } = load_resource( conn, claims, opts )
# This doesn't seem to do what I want
conn |> Guardian.Plug.sign_in( remember_user )
end
{ :error, reason } ->
# Do something
end
end
end
end
如何创建新令牌,将其存储在会话中并继续到所需的页面,而不是重新路由到登录页面?
答案 0 :(得分:2)
我猜代码可能是这样的:
defmodule MyApp.Plug.RememberMe do
import Plug.Conn
import Guardian.Plug
def init(opts \\ %{}), do: Enum.into(opts, %{})
def call(conn, _) do
current_user = current_resource(conn)
if ( current_user == nil ) do
jwt = conn.req_cookies["remember_me"]
case Guardian.decode_and_verify(jwt) do
{ :ok, claims } ->
the_key = Map.get(claims, :key, :default)
put_session(conn, Guardian.Keys.base_key(the_key), jwt)
end
end
end
end
在您的管道中,将MyApp.Plug.RememberMe
放在VerifySession
之前
请试着看看它是如何工作的
