过滤器名称常量定义 用于标识不同类型的过滤器,方便配置和管理
const ( UTF8 = "UTF-8" ANDROID = "android" IOS = "ios" WEB = "web" TEXT_PLAIN = "text/plain; charset=utf-8" APPLICATION_JSON = "application/json; charset=utf-8" NO_BODY = "no_body" GET = "GET" POST = "POST" PUT = "PUT" PATCH = "PATCH" DELETE = "DELETE" HEAD = "HEAD" OPTIONS = "OPTIONS" Authorization = "Authorization" Cipher = "Cipher" )
const ( DefaultWsRoute = "/ws" // 默认WebSocket路由路径 DefaultWsMaxBodyLen = 1024 * 1024 // 默认单条消息体最大 1MB,可通过 WsServer.SetMaxBodyLen 覆盖 )
WebSocket服务器实现
错误类型约定:
- 协议错误(客户端请求不合法、鉴权失败等):使用 ex.Throw{Code, Msg[, Err]},便于上层按 HTTP 状态码处理或回写。
- 配置/内部错误(校验配置、连接池、调用方参数等):使用 utils.Error,仅作日志或返回给调用方,无状态码需求。
WebSocket专用常量
Variables ¶
var ( MAX_BODY_LEN = 200000 // 最大参数值长度 MAX_TOKEN_LEN = 2048 // 最大Token值长度 MAX_CODE_LEN = 1024 // 最大Code值长度 )

type ConnectionContext ¶ added in v1.1.0
type ConnectionContext struct {
Subject *jwt.Subject
JsonBody *JsonBody
WsConn net.Conn // WebSocket 连接(gobwas/ws 使用 net.Conn)
DevConn *DevConn
Server *WsServer
RouterConfig *RouterConfig // 路由配置
Path string // WebSocket连接的路径
RawToken []byte // 原始JWT token字节,用于签名验证
// contains filtered or unexported fields
}
ConnectionContext 每个WebSocket连接的上下文,包含连接相关的所有信息。
设计要点:JsonBody 由 processMessage 从对象池获取并注入,业务 Handle 只读使用,不得在返回后继续持有。

func (cc *ConnectionContext) GetRawTokenBytes() []byte
GetRawTokenBytes 获取原始JWT token字节
func (*ConnectionContext) GetTokenSecret ¶ added in v1.1.0

GetUserID 获取用户ID int64类型
func (*ConnectionContext) GetUserIDString ¶ added in v1.1.0

type ConnectionManager ¶ added in v1.1.0
type ConnectionManager struct {
// contains filtered or unexported fields
}
ConnectionManager 连接管理器:线程安全的连接管理,支持广播、按 subject 推送、过期清理。
设计要点: - conns:二级 map subject -> deviceKey -> *DevConn,deviceKey 由 mode 决定(SubjectUnique 时为 sub,SubjectDeviceUnique 时为 sub_dev)。 - totalConn:原子计数,用于限流、Count()、以及 CleanupExpired/sendToSubjectByJsonResp 的 slice 预分配容量,避免在 RLock 内做重逻辑。 - 所有“收集 conn 再关闭/发送”的路径均在 RLock 内只收集指针,在锁外执行 I/O,避免持锁时间过长。
func NewConnectionManager ¶ added in v1.1.0
func NewConnectionManager(maxConn int, mode ConnectionUniquenessMode, broadcastKey string) *ConnectionManager
NewConnectionManager 创建连接管理器
func (*ConnectionManager) Add ¶ added in v1.1.0
func (cm *ConnectionManager) Add(conn *DevConn) error
Add 添加连接 Add 将连接加入管理器。根据连接唯一性模式决定策略: - SubjectUnique: 替换同 subject 的所有连接,只保留一个。 - SubjectDeviceUnique: 替换同 subject+device 的连接,允许多设备同时在线。 设备键格式:subject_device (如: user123_web, user123_app)
设计要点:若存在旧连接,先从 map 移除并减 totalConn,再在 goroutine 中 closeConn,避免锁内 I/O 阻塞。

func (*ConnectionManager) CleanupAll ¶ added in v1.1.0
func (cm *ConnectionManager) CleanupAll()
CleanupAll 关闭所有连接。先 RLock 内收集全部 conn 指针并预分配 slice,锁外再统一 closeConn,由各连接循环执行 RemoveByConn + ws.Close()。
func (*ConnectionManager) CleanupExpired ¶ added in v1.1.0
func (cm *ConnectionManager) CleanupExpired(timeoutSeconds int64) int
CleanupExpired 清理空闲超过 timeoutSeconds 的连接。
设计要点: - 在 RLock 内仅收集过期 conn 指针(LastSeen 为原子读无锁),RUnlock 后再 closeConn,避免持锁做 I/O。 - toClose 按 totalConn 预分配容量,减少 append 扩容与 GC。 - 超时判断依赖 DevConn.Last(每次收包/心跳 UpdateLast),由 HeartbeatService 按 idleTimeout 周期性调用。
func (*ConnectionManager) Count ¶ added in v1.1.0

func (*ConnectionManager) RemoveByConn ¶ added in v1.1.6
func (cm *ConnectionManager) RemoveByConn(conn *DevConn) bool
RemoveByConn 按连接指针从管理器中移除该连接。 设计要点:必须用指针精确匹配,避免“新连接已替换旧连接”时误把新连接从 map 删掉;关闭由 closeConnFromLoop 等调用方负责。 返回是否成功移除(若连接已被替换则未找到,返回 false)。
func (*ConnectionManager) RemoveWithCallback ¶ added in v1.1.0
func (cm *ConnectionManager) RemoveWithCallback(subject, deviceKey string, callback func()) *DevConn
RemoveWithCallback 移除连接并执行回调(用于指标记录)
func (*ConnectionManager) SendToSubject ¶ added in v1.1.0

// contains filtered or unexported fields

Conn net.Conn // WebSocket 连接(gobwas/ws)
// contains filtered or unexported fields
}
DevConn 设备连接实体:存储单连接的核心信息。
设计要点: - Last:使用原子读写(UpdateLast 写、LastSeen 读),使 CleanupExpired 遍历时无需对每条连接加 sendMu,降低高连接数下的锁竞争。 - sendMu:仅保护 Conn 的写与 closed 的可见性,Send/关闭路径使用;Last 不再依赖 sendMu。 - closeOnce:保证 ws.Close() 只执行一次,避免重复关闭导致 panic。
func (*DevConn) LastSeen ¶ added in v1.1.6
LastSeen 返回最近一次活跃时间。原子读、无锁,供 CleanupExpired 在 RLock 内批量调用而不产生 sendMu 竞争。
func (*DevConn) Send ¶ added in v1.1.0
