限速

启动限流中间件。

安装

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

选项

名字	描述	类型	默认值
gf.middleware.rateLimit.enabled	启动限流中间件	boolean	false
gf.middleware.rateLimit.ignore	局部选项，忽略 API 路径	[]string	[]
gf.middleware.rateLimit.algorithm	限流算法， 支持 leakyBucket	string	leakyBucket
gf.middleware.rateLimit.reqPerSec	全局限流值	int	1000000
gf.middleware.rateLimit.paths.path	访问路径	string	""
gf.middleware.rateLimit.paths.reqPerSec	基于访问路径的限流值	int	1000000

快速开始

1.创建 boot.yaml

---
gf:
  - name: greeter
    port: 8080
    enabled: true
    middleware:
      rateLimit:
        enabled: true
        paths:
          - path: "/v1/greeter"
            reqPerSec: 0
#        algorithm: "leakyBucket"
#        reqPerSec: 100

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

type GreeterResponse struct {
  Message string
}

3.验证

发送请求

$ curl "localhost:8080/v1/greeter?name=rk-dev"
{
    "error":{
        "code":429,
        "status":"Too Many Requests",
        "message":"",
        "details":[
            "slow down your request"
        ]
    }
}

Cheers
