micro env

env Get/set micro cli environment

 $ micro env
  local      none
* server     127.0.0.1:8081
  platform   proxy.m3o.com  

# set to use server
micro env set server

grpc api 和 http api 映射

https://m3o.com/docs/go-api.h...

比如 rpc call 如下

micro call go.micro.service.posts Posts.Query '{"slug":"how-to-micro"}'

对于http请求可以用 /rpc
参数 service, method, request

## post
curl -X "POST" "http://127.0.0.1:8082/rpc" \
     -H 'Content-Type: application/json; charset=utf-8' \
     -d $'{
  "service": "go.micro.service.posts",
  "": "Posts.Query",
  "request": {
    "slug": "how-to-micro"
  }
}'
