Quick start

1.Create boot.yaml

---
gf:
  - name: greeter
    port: 8080
    enabled: true
    middleware:
      jwt:
        enabled: true
        symmetric:
          algorithm: HS256
          token: "my-secret"
#          tokenPath: ""
#        signerEntry: ""
#        ignore: [ "" ]
#        skipVerify: false
#        asymmetric:
#          algorithm: ""
#          privateKey: ""
#          privateKeyPath: ""
#          publicKey: ""
#          publicKeyPath: ""
#        tokenLookup: "header:<name>"
#        authScheme: "Bearer"

2.Create main.go

package main

import (
  "context"
  "fmt"
  "github.com/gogf/gf/v2/net/ghttp"
  "github.com/rookie-ninja/rk-boot/v2"
  "github.com/rookie-ninja/rk-gf/boot"
  "github.com/rookie-ninja/rk-gf/middleware/context"
  "net/http"
)

func main() {
  // Create a new boot instance.
  boot := rkboot.NewBoot()

  // Register handler
  entry := rkgf.GetGfEntry("greeter")
  entry.Server.BindHandler("/v1/greeter", Greeter)

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

  boot.WaitForShutdownSig(context.TODO())
}

func Greeter(ctx *ghttp.Request) {
  // Get JWT token
  rkgfctx.GetJwtToken(ctx)

  ctx.Response.WriteHeader(http.StatusOK)
  ctx.Response.WriteJson(&GreeterResponse{
    Message: fmt.Sprintf("Hello %s!", ctx.GetQuery("name").String()),
  })
}

type GreeterResponse struct {
  Message string
}

3.Validate

• Valid JWT Token

$ curl "localhost:8080/v1/greeter?name=rk-dev" -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.EpM5XBzTJZ4J8AfoJEcJrjth8pfH28LWdjLo90sYb9g"
{"Message":"Hello rk-dev!"}

• Invalid JWT Token

  $ curl localhost:8080/v1/greeter -H "Authorization: Bearer invalid-jwt-token"
  {
      "error":{
          "code":401,
          "status":"Unauthorized",
          "message":"Invalid or expired jwt",
          "details":[]
      }
  }
