Qt-A comprehensive example of obtaining network interface information

In the previous article, it is described that there are 4 commonly used classes related to acquiring native network information, namely: Qhostaddress, Qhostinfo, Qnetworkinterface and Qnetworkaddress Entry. These 4 classes are not described in detail, we mainly use these 4 classes of common methods to obtain information about the network interface.
