支持 fasthttp 的 websocket 库

• https://github.com/fasthttp-contrib/websocket
• https://github.com/leavengood/websocket
• https://github.com/clevergo/websocket fork 上面，去掉了支持net/http 功能，改进了Upgrader

补充最近2021年还活跃的库

• https://github.com/fasthttp/fastws
• https://github.com/fasthttp/websocket 最近（2021）还活跃的

以上 3 个都fork from https://github.com/gorilla/websocket

fasthttp-contrib/websocket 一个☝️栗子🌰

import (
	"github.com/fasthttp-contrib/websocket"
	"github.com/vayala/fasthttp"
)

func chat(c *websocket.Conn) {
	// defer c.Close()
	// mt, message, err := c.ReadMessage()
	// c.WriteMessage(mt, message)
}

var upgrader = websocket.New(chat) // use default options
//var upgrader = websocket.Custom(chat, 1024, 1024) // customized options, read and write buffer sizes (int). Default: 4096
// var upgrader = websocket.New(chat).DontCheckOrigin() // it's useful when you have the websocket server on a different machine

func myChatHandler(ctx *fasthttp.RequestCtx) {
	err := upgrader.Upgrade(ctx)// returns only error, executes the handler you defined on the websocket.New before (the 'chat' function)
}

func main() {
	fasthttp.ListenAndServe(":8080", myChatHandler)
}
