We developed a web application that uses websocket, but when using safari browser, there is always a problem that the websocket connection cannot be established. Both Google Chrome and Firefox browsers can be used normally, when we close the nsurlsession websocket of Safari ,Can be used normally. But we can't ask all users to close this experimental feature, and closing this nsurlsession websocket will affect the redirection of our enterprise WeChat, so I want to know how to solve this problem.
