README

服务端

  • Config 配置信息
    • ServiceName 服务名称
    • ServiceEndpoint 服务开放地址
    • Addr 服务监听地址,必须明确 ip:port
  • 信号监控
    • kill -USR1 开启 pprof 监控
    • kill -USR2 停止 pprof 监控,可以获取监控文件
    • kill -1 平滑重启
    • kill -9 退出应用程序,目前监控不到
    • kill -QUIT 退出应用程序
    • ctrl + C 退出应用程序
  • 拦截器
    • grpc.ChainUnaryInterceptor 服务端单向拦截器(也叫"一元拦截器")
      • serverUnaryInterceptorLog() 记录日志信息
      • unaryServerInterceptorAuth() 鉴权处理
        • AuthFunc() 自定义鉴权方法
    • grpc.ChainStreamInterceptor 服务端流式拦截器
      • 同上
  • Register2ETCD() 服务注册到etcd
    • key 格式: /
    • value 格式: json格式,示例 {"Op":0,"Addr":"127.0.0.1:19001","Metadata":null}

客户端

  • Dial() 链接 grpc
  • DialWithEtcd() 通过 etcd 链接 grpc
    • target 格式 etcd:///<service>
  • 返回拦截

grpc 版本要求

最高使用 v1.52.3, 否则导致 Target.Endpoint 无效,因为高版本把属性定义为了方法
