Functions

func Dial

func Dial(name string, opts ...Option) (*grpc.ClientConn, error)

Dial returns a load balanced grpc client conn with tracing interceptor

Types

type Option func(*Options)

func WithDialOption

func WithDialOption(gopts ...grpc.DialOption) Option

func WithTraceIdFunc

func WithTraceIdFunc(idFunc tracing.ClientTraceIdFunc) Option

func WithTracer

func WithTracer(t opentracing.Tracer) Option

WithTracer traces rpc calls,the Tracer interceptor must put the last because the context get value limit if use jeagertracer,the context header key will be uber-trace-id,it can't log by zap logger. if you want auto log by CtxTag,the key must be TagTraceID value,set the jeager's configuration key headers.TraceContextHeaderName to `trace.traceid`
