C++ 使用Winsock c++；

我目前正在进行一个项目，尝试使用蓝牙和Winsock连接两台PC，我的想法是在它们之间建立一个服务器/客户端连接，并将一个字符串从客户端发送到服务器，但不幸的是，它没有像我预期的那样工作

当我运行服务器代码时，它一直在等待客户机请求，并且只在控制台中显示“Listen（）正常！正在侦听连接”。当我运行客户端代码时，它会运行整个代码，直到它显示消息“WSACleanUp（）工作正常”。我把两台电脑配对，因为我认为有必要这样做

我最初的猜测是客户端到服务器的连接不工作。我是Winsock新手，我正在努力寻找能够帮助我解决这些问题的准确信息（除了以前发布的一些问题和来自windows的文档）
