快速开始#

1.创建 boot.yaml#

---
gin:
  - name: greeter
    port: 8080
    enabled: true
    middleware:
      csrf:
        enabled: true
#        ignore: [""]
#        tokenLength: 32
#        tokenLookup: "header:X-CSRF-Token"
#        cookieName: "_csrf"
#        cookieDomain: ""
#        cookiePath: ""
#        cookieMaxAge: 86400
#        cookieHttpOnly: false
#        cookieSameSite: "default"

2.创建 main.go#

package main

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

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

  // Register handler
  entry := rkgin.GetGinEntry("greeter")
  entry.Router.POST("/v1/greeter", Greeter)

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

  boot.WaitForShutdownSig(context.TODO())
}

func Greeter(ctx *gin.Context) {
  ctx.JSON(http.StatusOK, &GreeterResponse{
    Message: fmt.Sprintf("Hello %s!", ctx.Query("name")),
  })
}

type GreeterResponse struct {
  Message string
}

3.验证#

  • 发送 GET 请求, 对于 GET 请求,一个新的 Cookie 将会返回。
$ curl -X GET -vs localhost:8080/v1/greeter
  ...
  < HTTP/1.1 200 OK
  < Content-Type: application/json; charset=UTF-8
  < Set-Cookie: _csrf=WyOJLwzhfUGAMDHglkuIRucdpalxolWg; Expires=Mon, 06 Dec 2021 18:38:45 GMT
  < Vary: Cookie
  < Date: Sun, 05 Dec 2021 18:38:45 GMT
  < Content-Length: 22
  <
  {"Message":"Hello !"}
  • 发送 POST 请求,通过 CSRF 验证。
$ curl -X POST -v --cookie "_csrf=my-test-csrf-token" -H "X-CSRF-Token:my-test-csrf-token" localhost:8080/v1/greeter
...
> Accept: */*
> Cookie: _csrf=my-test-csrf-token
> X-CSRF-Token:my-test-csrf-token
> 
< HTTP/1.1 200 OK
< Content-Type: application/json; charset=utf-8
< Set-Cookie: _csrf=my-test-csrf-token; Expires=Sun, 17 Apr 2022 12:41:46 GMT
< Vary: Cookie
< Date: Sat, 16 Apr 2022 12:41:46 GMT
< Content-Length: 27
< 
{"Message":"Hello rk-dev!"}
  • 发送 POST 请求,携带非法 CSRF。
$ curl -X POST -v -H "X-CSRF-Token:my-test-csrf-token" localhost:8080/v1/greeter
...
> X-CSRF-Token:my-test-csrf-token
>
< HTTP/1.1 403 Forbidden
< Content-Type: application/json; charset=UTF-8
< Date: Sat, 16 Apr 2022 12:42:27 GMT
< Content-Length: 114
<
{"error":{"code":403,"status":"Forbidden","message":"Invalid csrf token","details":[null]}}
