Metadata

This is an example of sending metadata/headers.

HTTP headers sent to the micro api will be converted to metadata and forwarded on.

Contents

• srv - an RPC service which extracts metadata
• cli - an RPC client that calls the service once

Deps

Service discovery is required for all services. Default is Consul or MDNS. You can also use plugins from micro/plugins.

MDNS

Use the flag --registry=mdns

Consul

brew install consul
consul agent -dev

Run Service

Start go.micro.srv.greeter

go run srv/main.go

Client

Call go.micro.srv.greeter via client

go run cli/main.go
