Constant

constant 包定义了微服务通信中通用的 HTTP Header / gRPC Metadata Key。

常用常量

这些常量主要用于 gRPC Metadata 或 HTTP Header 中传递上下文信息。

身份与追踪

TraceId：全链路追踪 ID（ff-trace-id）
Session：会话标识（ff-session）
Authorization：认证令牌（authorization）
UserId：用户 ID（ff-user-id）
AppId：应用 ID（ff-app-id）
TenantId：租户 ID（ff-tenant-id）
ClientIp：客户端 IP（ff-client-ip）
XRealIp：反向代理透传真实 IP（x-real-ip）

客户端信息

SystemName / SystemVersion：系统名称与版本
ClientName / ClientVersion：客户端名称与版本
SystemType / ClientType：系统/客户端类型
DeviceFormFactor：设备形态
AppVersion / AppLanguage：应用版本 / 语言

使用示例

import "github.com/fireflycore/go-micro/constant"

// 从 gRPC metadata 获取 TraceId
md, _ := metadata.FromIncomingContext(ctx)
traceId := md.Get(constant.TraceId)
