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>
