Pings have an opcode of 0x9, and pongs have an opcode of 0xA. When you get a ping, send back a pong with the exact same Payload Data as the ping (for pings and pongs, the max payload length is 125). You might also get a pong without ever sending a ping; ignore this if it happens. NEO Ping with Golang.

The WebSocket Protocol enables two-way communication between a client running untrusted code in a controlled environment to a remote host that has opted-in to communications from that code. The security model used for this is the origin-based security model commonly used by web browsers. The protocol consists of an opening handshake followed by basic message framing, layered over TCP.

I’m Sergey kamardin, an engineer at mail.ru. This article mainly introduces how to use go to develop high load websocket services. If you are familiar with WebSockets but don’t know much about go, I hope you are interested in the ideas and performance optimization aspects of this article. 1. introduction In order to […] Unmarshal JSON into a map in Go. json,dictionary,go. I believe that is because you have extra layer of indirection in your models. type JSONType struct { FirstSet map[string]string `json:"set1"` } Should suffice.

WebSocket enables bidirectional, message-oriented streaming of text and binary data between client and server. It is the closest API to a raw network socket in the browser. A large number of online connections require the solution of interesting and sometimes ambiguous tasks. Here are a few techniques for performance optimization when it comes to Go and WebSockets.
