Custom route

How to define custom route in grpc-gateway?

Overview

User can add custom HTTP handler into grpc-gateway.

Quick start

• Install

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

1.Create boot.yaml

---
grpc:
  - name: greeter
    port: 8080
#   gwPort: 8081                  # Optional, default: gateway port will be the same as grpc port if not provided
    enabled: true

2.Create main.go

package main

import (
  "context"
  "github.com/rookie-ninja/rk-boot/v2"
  "github.com/rookie-ninja/rk-grpc/v2/boot"
  "net/http"
)

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

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

  // register grpc
  entry := rkgrpc.GetGrpcEntry("greeter")

  // !!!!!!
  // This codes should be located after Bootstrap()
  entry.GwMux.HandlePath("GET", "/custom", func(w http.ResponseWriter, r *http.Request, pathParams map[string]string) {
    w.Write([]byte("Custom routes!"))
  })

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

3.Validate

$ curl "localhost:8080/custom"
Custom routes!
