Swagger UI

Enable Swagger UI.

Install

go get github.com/rookie-ninja/rk-boot/v2
go get github.com/rookie-ninja/rk-grpc/v2

Swagger options

name	description	type	default value
grpc.sw.enabled	Enable Swagger UI	boolean	false
grpc.sw.path	Path of Swagger Web UI	string	sw
grpc.sw.jsonPath	Path Swagger config（swagger.json）file	[]string	[]
grpc.sw.headers	Headers returned by server, format: [key:value]	[]string	[]

Quick start

1.Create and compile protocol buffer

Compile protobuf

2.Create boot.yaml

rk-boot will search docs/, api/gen/v1/ folder for swagger JSON file

If swagger JSON located at other location，grpc.sw.jsonPath needs to be configured

---
grpc:
  - name: greeter
    port: 8080
#   gwPort: 8081                  # Optional, default: gateway port will be the same as grpc port if not provided
    enabled: true
    sw:
      enabled: true
#      jsonPath: []
#      path: "sw"
#      headers: []

3.Create main.go

package main

import (
  "context"
  "github.com/rookie-ninja/rk-boot/v2"
  "github.com/rookie-ninja/rk-demo/api/gen/v1"
  "github.com/rookie-ninja/rk-grpc/v2/boot"
  "google.golang.org/grpc"
)

func main() {
  boot := rkboot.NewBoot()

  // register grpc
  entry := rkgrpc.GetGrpcEntry("greeter")
  entry.AddRegFuncGrpc(registerGreeter)
  entry.AddRegFuncGw(greeter.RegisterGreeterHandlerFromEndpoint)

  // Bootstrap
  boot.Bootstrap(context.TODO())

  // Wait for shutdown sig
  boot.WaitForShutdownSig(context.TODO())
}

func registerGreeter(server *grpc.Server) {
  greeter.RegisterGreeterServer(server, &GreeterServer{})
}

type GreeterServer struct{}

func (server *GreeterServer) Hello(_ context.Context, _ *greeter.HelloRequest) (*greeter.HelloResponse, error) {
  return &greeter.HelloResponse{
    Message: "hello!",
  }, nil
}

4.Start main.go

$ go run main.go
