Websocket 与 phoenix 连接失败

Question

App.js:7 WebSocket connection to 'ws://localhost:4000/socket/websocket?token=undefined&vsn=2.0.0' failed: 

然后在日志中

  Transport: :websocket
  Serializer: Phoenix.Socket.V2.JSONSerializer
  Parameters: %{"token" => "SFMyNTY.g2gDYQFuBgBoR0bYggFiAAFRgA._1bc8_ag00XMoZ1WXaqBcIvnaq5muBMW2AUSQ7Avoy0", "vsn" => "2.0.0"}
[info] REFUSED CONNECTION TO RotbWeb.UserSocket in 30µs
  Transport: :websocket
  Serializer: Phoenix.Socket.V2.JSONSerializer
  Parameters: %{"token" => "undefined", "vsn" => "2.0.0"}
[info] REFUSED CONNECTION TO RotbWeb.UserSocket in 35µs
  Transport: :websocket
  Serializer: Phoenix.Socket.V2.JSONSerializer
  Parameters: %{"token" => "undefined", "vsn" => "2.0.0"}
[info] REFUSED CONNECTION TO RotbWeb.UserSocket in 104µs

这些错误过去是间歇性的，我只是等待，它会自行解决，但看起来它不再自行解决。

当 Socket 连接被拒绝时，您可能需要检查连接回调。

def connect(params, socket, info) do
  
  # You are doing something here that makes the connect fail.

end

我的猜测是令牌是

undefined

，您可能正在验证令牌或某些失败并导致连接失败的条件。
