我有一個連接到網絡套接字的問題。有一個錯誤:ActionCable - 無法升級到WebSocket
Successfully upgraded to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: Upgrade, HTTP_UPGRADE: websocket)
User Load (0.2ms) SELECT "users".* FROM "users" WHERE "users"."id" IS NULL LIMIT ? [["LIMIT", 1]]
An unauthorized connection attempt was rejected
Failed to upgrade to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: Upgrade, HTTP_UPGRADE: websocket)

connection.rb
module ApplicationCable
class Connection < ActionCable::Connection::Base
identified_by :current_user
def connect
self.current_user = find_verified_user
logger.add_tags 'ActionCable', "User #{current_user.id}"
end
protected
def find_verified_user
if verified_user = User.find_by(id: cookies.signed[:user_id])
verified_user
else
reject_unauthorized_connection
end
end
end
end
我找到了一些解決方案,我應該使用config.allowed_request_origins
,但它並沒有解決我的問題。我試着用session_helper加入這個方法:
def set_cookie(user)
the_username = user.username.to_s
cookies.permanent.signed[:username] = the_username
end
沒有修復我的問題。
更新: 我看到問題是cookie.signed [:user_id]爲零。你有什麼建議可以解決這個問題的原因?我使用標準的URL和端口進行測試(localhost:3000)。
這還不夠。這樣,您只需在用戶登錄時刪除錯誤。但如果用戶未登錄 - **錯誤仍然存在**。這是因爲「room.coffee」中的App.room = App.cable.subscriptions.create「RoomChannel」'call'(或類似於你的代碼)。解決方法是根據用戶是否登錄來有條件地呈現'room.coffee',但這需要從資產中排除'room.coffee' - 並單獨呈現(因爲您無法有條件地呈現js if用戶登錄/退出)。 – prograils
