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

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