Xmpp is connected to the server and authenticated successfully. xmpp is used for authentication.

Xmpp is connected to the server and authenticated successfully. xmpp is used for authentication.

* XMPP features that all requests are implemented through proxy
*
* Because xmpp communicates data through the network server, all requests are submitted to the server for processing.
*
* After the server is processed, it stops vomiting and notifies the client of the processing result as a proxy.
*
* AppDelegate is officially recommended to process all proxy responses from XMPP servers.
