问Poco::Net::SocketStream不存在默认构造函数EN首先，您需要一个StreamSocket(即TCP套接字)。然后，您可以从它创建一个SocketStream。在初学C++的时候，对于一个对象来说，如果我们没有去定义其默认构造函数，那么编译器就会为我们自动生成一个默认构造函数。但其实是不准确的，具体来说是编译器会在必要的时候来生成一个默认构造函数，那么这个...
Socket(SocketType, ProtocolType) Initializes a new instance of theSocketclass using the specified socket type and protocol. If the operating system supports IPv6, this constructor creates a dual-mode socket; otherwise, it creates an IPv4 socket. ...
