练手小项目，为熟悉Gin框架跟websocket使用
💛 💛 💛 💛 💛 💛
在线demo (PS: 请尽量使用Chrome游览器，开启多个不同用户游览器即可体验效果)
feature
- 登录/注册(防止重复登录)
- 群聊(多房间、支持文字、emoji、文件(图片)上传，使用 freeimage.host 做图床 )
- 私聊(消息提醒)
- 历史消息查看(点击加载更多)
- 心跳检测，来自 https://github.com/zimv/websocket-heartbeat-js
- go mod 包管理
- 使用 Golang 1.16 embed 内嵌静态资源(html、js、css等)，运行只依赖编译好的可执行文件与mysql
- 支持 http/ws 、 https/wss

- 定义客户端信息的结构体
type wsClients struct {
Conn *websocket.Conn `json:"conn"`
RemoteAddr string `json:"remote_addr"`
Uid float64 `json:"uid"`
Username string `json:"username"`
RoomId string `json:"room_id"`
AvatarId string `json:"avatar_id"`
}
// - 定义全局变量
// client & serve 的消息体
type msg struct {
Status int `json:"status"`
Data interface{} `json:"data"`
Conn *websocket.Conn `json:"conn"`
}
// 上线、离线、消息发送事件 的 无缓冲区的 channel
var (
clientMsg = msg{}
enterRooms = make(chan wsClients)
sMsg = make(chan msg)
offline = make(chan *websocket.Conn)
chNotify = make(chan int ,1)
)- 使用 make 创建一个全局的
map slice用于存放房间与用户的信息，用户上线、离线实际上是对map的 append 跟 remove
var (
rooms = make(map[int][]wsClients)
)- 开启
goroutine处理用户的连接、离线、消息发送等各个事件

编译可执行文件(跨平台)
# 用法参考 https://github.com/mitchellh/gox
# go install github.com/mitchellh/gox@latest (go 1.18)
# 生成文件可直接执行 Linux
gox -osarch="linux/amd64" -ldflags "-s -w" -gcflags="all=-trimpath=${PWD}" -asmflags="all=-trimpath=${PWD}"
