Solution au problème selon lequel le serveur de déploiement WebSocket ne peut pas se connecter au réseau externe

La première chose que je veux dire est le problème que j'ai rencontré :

Version 2017 de la version webSocket des années 80 Version  4. Version 2017 de la version webSocket version 2017效总结 80端口可能受系统限制另一方面:域名绑定是否会影响 没有测试 成功解决了外网虽返回200却不能使用websocket服务的问题。这种情况下需要注意的是， Il s'agit d'un système IIS qui fonctionne avec WebSocket et WebSocket.个网站可以使用同一个程序版本，我就是这么做的，没有什么好的想法，菜鸟级人物。 这个网站介绍了WebSocket的一些知识，以及websocket默认使用80-433端口，或许我在想，是不是我网站绑定的端口和websocket绑定相同端口时，外网请求就是此时出的错呢，这个问题也一时半会不能深究，暂时性的功能是达到了，但是感觉只能是说满足了需求，却不能简化需求过程。 留下一个猜想，我在服务器上访问时，是可行的，都是使用80端口，websocket服务能够正常使用，那是因为在服务器上发起时、 Il s'agit d'une application WebSocket, d'une application WebSocket et d'une application WebSocket.防火墙识别出问题。 </span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span>
