1、用法Poco C+库创建websocket平安访问(wss)客户端_ Poco websocket库特点: 1,用法http/https ClientSession创建websocket client 2,是同步的,这对C+桌面编程来说应当是够用的. 3,依靠openssl. 代码如下 #include stdafx.h #include iostream #include assert.h #include Poco/Net/WebSocket.h #include Poco/Net/HTTPClientSession.h #include Poco/Net/HTTPRequest.h #i
2、nclude Poco/Net/HTTPResponse.h #include Poco/Net/ServerSocket.h #include Poco/Net/NetException.h #include Poco/Exception.h #include Poco/Net/HTTPSClientSession.h #include Poco/URIStreamOpener.h #include Poco/StreamCopier.h #include Poco/Path.h #include Poco/URI.h #include Poco/SharedPtr.h #include P
3、oco/Exception.h #include Poco/Net/HTTPStreamFactory.h #include Poco/Net/HTTPSStreamFactory.h #include Poco/Net/FTPStreamFactory.h #include Poco/Net/SSLManager.h #include Poco/Net/KeyConsoleHandler.h #include Poco/Net/ConsoleCertificateHandler.h #include Poco/Net/AcceptCertificateHandler.h #include P
4、oco/Net/SecureStreamSocket.h #include Poco/Net/X509Certificate.h #include memory using Poco:Net:HTTPSClientSession; using Poco:Net:HTTPClientSession; using Poco:Net:HTTPRequest; using Poco:Net:HTTPResponse; using Poco:Net:HTTPServerRequest; using Poco:Net:HTTPServerResponse; using Poco:Net:WebSocket
