problem description
java uses native code to write websocket,. I link through socket.io-client, and the service passes third-party tests, such as http://www.blue-zero.com/WebS.
, but the code just doesn"t link.
the environmental background of the problems and what methods you have tried
if you do not add transports: ["websocket"], , the rotation training method used, do not report failed, but connect_error.
if you add it, you will report that the link has failed, and you will not be able to connect directly.
