Create a WebSocket secure access (WSS) client using the Poco C + + library

Poco WebSocket Library Features:

1, create WebSocket client using Http/https clientsession

2, is synchronized, this should be sufficient for C + + desktop programming.

3, rely on OpenSSL.

The code is as follows

#include "stdafx.h" #include <iostream> #include <assert.h>   #include "poco/net/websocket.h" #include "Poco/net/httpclientsession.h" #include "poco/net/httprequest.h" #include "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 "Poco/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 "poco/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; using Poco::net::websocketexception; using Poco::exception;   using Poco::uristreamopener; using Poco::streamcopier; using Poco::P ath; using Poco::uri; using Poco::sharedptr; using Poco::exception; using Poco::net::httpstreamfactory; using Poco::net::httpsstreamfactory; using Poco::net::ftpstreamfactory; using Poco::net::sslmanager; using Poco::net::context; using Poco::net::keyconsolehandler; using poco::net::P rivatekeypassphrasehandler; using Poco::net::invalidcertificatehandler; using Poco::net::consolecertificatehandler; using Poco::net::acceptcertificatehandler; using Poco::net::x509certificate;     int main (int argc, _tchar* argv[]) { Char buffer[1024]; int flags; int n; std::string payload;       Try     {           Poco::net::initializessl ();   sharedptr<invalidcertificatehandler> Pcert = new Consolecertificatehandler (false); Ask the user via console Context::P TR PContext = new context (Context::tlsv1_client_use, "", "", "Rootcert.pem", context::verify_relaxed, 9, False , "all:! Adh:! low:! Exp:! MD5: @STRENGTH "); sslmanager::instance (). Initializeclient (0, Pcert, pContext);           httpsclientsession cs ("echo.websocket.org", 443); HttpRequest request (Httprequest::http_get, "/", "http/1.1"); HttpResponse response; std::string cmd;   WebSocket * ws = new WebSocket (CS, request, response); Causes the timeout payload = "Shakethand"; Ws->sendframe (Payload.data (), Payload.size (), websocket::frame_text); n = ws->receiveframe (buffer, sizeof (buffer), flags);           std::cout<< "return:" <<std::string (buffer,n) << "\ n"; Ws->shutdown ();               }       catch (poco::exception& ex)     { Std::cout << "Error: <<__FILE__<<": "<<__LINE__<<": "<< Ex.displaytext () <   < "\ n"; return-1;     } return 0;       }

WS client creation is no longer redundant, and there are examples from the authorities.
