GoFrame 框架（rk-boot）：开启 TLS/SSL

介绍

通过一个完整例子，在 gogf/gf 框架中开启 TLS/SSL，我就是我们常说的 https。

我们将会使用 rk-boot 来启动 gogf/gf 微服务。

请访问如下地址获取完整教程：

• https://rkdocs.netlify.app/cn

生成 Self-Signed Certificate

用户可以从各大云厂商购买证书，或者使用 cfssl 创建自定义证书。

我们介绍如何在本地生成证书。

1.下载 cfssl & cfssljson 命令行

推荐使用 rk 命令行来下载。

代码语言：shell script复制

$ go get -u github.com/rookie-ninja/rk/cmd/rk
$ rk install cfssl
$ rk install cfssljson

官网下载

代码语言：shell script复制

$ go get github.com/cloudflare/cfssl/cmd/cfssl
$ go get github.com/cloudflare/cfssl/cmd/cfssljson

2.生成 CA

代码语言：shell script复制

$ cfssl print-defaults config > ca-config.json
$ cfssl print-defaults csr > ca-csr.json

根据需要修改 ca-config.json 和 ca-csr.json。

代码语言：shell script复制

$ cfssl gencert -initca ca-csr.json | cfssljson -bare ca -

3.生成服务端证书

server.csr，server.pem 和 server-key.pem 将会被生成。

代码语言：shell script复制

$ cfssl gencert -config ca-config.json -ca ca.pem -ca-key ca-key.pem -profile www ca-csr.json | cfssljson -bare server

安装

代码语言：go复制

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

快速开始

rk-boot 支持通过如下方式让 gogf/gf 服务获取证书。

• 本地文件系统
• 远程文件系统
• Consul
• ETCD

我们先看看如何从本地获取证书并启动。

1.创建 boot.yaml

在这个例子中，我们只启动服务端的证书。其中，locale 用于区分不同环境下 cert。

请参考之前的文章了解详情：

代码语言：yaml复制

---
cert:
  - name: "local-cert"                     # Required
    provider: "localFs"                    # Required, etcd, consul, localFs, remoteFs are supported options
    locale: "*::*::*::*"                   # Required, default: ""
    serverCertPath: "cert/server.pem"      # Optional, default: "", path of certificate on local FS
    serverKeyPath: "cert/server-key.pem"   # Optional, default: "", path of certificate on local FS
gf:
  - name: greeter
    port: 8080
    enabled: true
    enableReflection: true
    cert:
      ref: "local-cert"                    # Enable grpc TLS

2.创建 main.go

代码语言：go复制

package main

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

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

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

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

	boot.WaitForShutdownSig(context.TODO())
}

// @Summary Hello
// @Id 1
// @Tags Hello
// @version 1.0
// @produce application/json
// @Success 200 string string
// @Router /v1/hello [get]
func hello(ctx *ghttp.Request) {
	ctx.Response.WriteHeader(http.StatusOK)
	ctx.Response.WriteJson(map[string]string{
		"message": "hello!",
	})
}

3.文件夹结构

代码语言：shell script复制

.
├── boot.yaml
├── cert
│   ├── server-key.pem
│   └── server.pem
├── go.mod
├── go.sum
└── main.go

1 directory, 6 files

4.启动 main.go

代码语言：shell script复制

$ go run main.go

5.验证

代码语言：shell script复制

$ curl -X GET --insecure https://localhost:8080/v1/hello     
{"message":"hello!"}
