嗨，Parth，我想你的方法可以让更多的东西工作，但我仍然无法在模拟服务器端获得连接（也就是说，当我运行node app.js，然后单击按钮时，没有任何东西打印到控制台，这很奇怪…）我将用Xcode打印的日志更新我的代码，非常感谢你——我认为这真的很接近工作状态！旁注：再次查看输出，我意识到connect（）函数中的print语句从未被命中，因此这可能是我们遇到的问题…我还必须删除.version（.two）并用我的ip地址替换（WebService.SOCKET_URL）：3000字符串URL来编译整个内容——这仍然是正确的，对吗？@nickcoding yes您应该将url替换为您正在使用的url，并且可以删除.version（.two）如果在节点上使用socket.io版本3side@nickcoding你能在这里发布你的日志吗？这样我就可以看一看了。我在编辑的问题中发布了我的日志。我在终端中得到的唯一日志是“监听端口3000”，之后就什么都没有了……看起来客户端和服务器正在连接，客户端注册了它连接，但我的计算机上的模拟服务器没有，因为终端上没有显示“用户已连接”，所以…我以前有app.get（“/”，（req，res）=>{res.send（'var socket=io（）；Hello world'）；}）；在我的代码中，当我把本地主机放到浏览器中，并且在终端上得到一个用户连接指示时，我可以得到一个HTML窗口，我只是不明白为什么我在使用swift时没有得到终端打印输出（也就是点击按钮，它应该在终端上打印出已经建立了连接）。另外，我对您对Parth解决方案的评论发表了评论，谢谢！
