我正在尝试开发一个应用程序，其中android客户端通过Socket编程从Python服务器发送和接收数据。没有错误也没有任何异常崩溃但我的客户端无法访问python服务器，因为我的服务器没有从任何客户端接收任何连接。我关闭了我的Windows防火墙，以便我的电脑不会阻止未知的访问。我尝试在堆栈交换中引用类似的文章，但他们都说他们正在接收来自客户端的连接。请告诉我我的代码有什么问题。 先感谢您。 （在我的服务器代码中，如果我使用我的PC的IP地址，那么它显示错误10049，所以我使用的是localhost IP）

我的python代码在Pycharm上运行，因此我必须在管理员模式下运行它，并确保使用try和except块来包围bind函数。每次运行程序时都要更改端口号，并在首次执行之前关闭Windows防火墙，将PC的IP地址用作主机地址。现在它有效 -
