实现用c++在win7下,扫描可用的本地连接

Windows下使用Wifi Native Api在应用程序内部控制wifi，官方文档链接https://docs.microsoft.com/zh-cn/windows/win32/nativewifi/native-wifi-api-sample，主要注意以下几点：

  • 连接wifi使用wlan_connection_mode_profile时，如果被连接的wifi有配置文件，那么连接参数直接使用配置文件名称即可，如果没有配置文件，要先WlanSetProfile成功后才能创建连接，不同的加密方式有不同的配置文件样本，常用的WPA2样本WPA2-Personal Profile Sample
  • 官方的配置文件样本有个坑，官方的xml demo里面命名空间是https，实际使用的是http才能WlanSetProfile成功，否则会报ERROR_BAD_PROFILE错误
  • 连接wifi前需要断开当前已经连接的wifi
  • WlanRegisterNotification的回调函数接收通知是系统全局的，也就是说在系统设置里面操作wifi也能通知回调，并且是异步回调

下面是根据官方文档和demo写的demo，结合Qt
