一套代码，同时启动 7 种 Golang Web 框架

今天我们来做一个有趣的 Go 实践。使用同一套代码，在一个进程中，同时启动 7种不同的 Go Web 框架。

为什么做这么无聊的事儿？

主要目的就是介绍 rookie-ninja/rk-boot 库。

启动哪些 Go Web 框架？

我们同时启动如下几个 Go Web 框架。

Web 框架	rk-boot 依赖	版本
gin-gonic/gin	go get github.com/rookie-ninja/rk-boot/gin	v1.2.14 (Stable)
gRPC	go get github.com/rookie-ninja/rk-boot/grpc	v1.2.18 (Stable)
labstack/echo	go get github.com/rookie-ninja/rk-boot/echo	v0.0.8 (Stable)
gogf/gf	go get github.com/rookie-ninja/rk-boot/gf	v0.0.6 (Stable)
gofiber/fiber	go get github.com/rookie-ninja/rk-boot/fiber	v0.0.4 (Testing)
zeromicro/go-zero	go get github.com/rookie-ninja/rk-boot/zero	v0.0.2 (Testing)
gorilla/mux	go get github.com/rookie-ninja/rk-boot/mux	v0.0.2 (Testing)

快速开始

1.安装

我们通过 go get 安装如下依赖。

代码语言：txt复制

go get github.com/rookie-ninja/rk-boot/grpc
go get github.com/rookie-ninja/rk-boot/gin
go get github.com/rookie-ninja/rk-boot/echo
go get github.com/rookie-ninja/rk-boot/gf
go get github.com/rookie-ninja/rk-boot/fiber
go get github.com/rookie-ninja/rk-boot/zero
go get github.com/rookie-ninja/rk-boot/mux

2.创建 boot.yaml

Web 框架	端口
gRPC	8081
gin-gonic/gin	8082
labstack/echo	8083
gogf/gf	8084
gofiber/fiber	8085
zeromicro/go-zero	8086
gorilla/mux	8087

除了指定端口，我们还开启了如下两个选项：

• commonService: 提供 /rk/v1/healthy 这类通用 API。
• loggingZap: RPC 日志

  - name: grpc
    port: 8081

echo:
  - name: echo
    port: 8083
    enabled: true
    commonService:

    interceptors:

gf:
  - name: gf

    enabled: true
    commonService:
      enabled: true                   # Optional, default: false
    interceptors:
      loggingZap:
        enabled: true                 # Optional, default: false
fiber:
  - name: fiber
    port: 8085
    enabled: true
    commonService:
      enabled: true                   # Optional, default: false
    interceptors:
      loggingZap:
        enabled: true                 # Optional, default: false

  - name: zero
    port: 8086
    enabled: true
    commonService:
      enabled: true                   # Optional, default: false
    interceptors:
      loggingZap:
        enabled: true                 # Optional, default: false
mux:
  - name: mux
    port: 8087
    enabled: true
    commonService:
      enabled: true                   # Optional, default: false
    interceptors:
      loggingZap:
        enabled: true                 # Optional, default: false

3.创建 main.go

所有 Web 框架都是用 handleRequest() 函数来处理请求。

gRPC 例外，我们没有使用 protocol buffer，因为 PB 的协议不同。我们使用 grpc-gateway 来模拟。

grpcEntry 默认会开启 grpc-gateway，通过 grpcEntry.HttpMux 往 grpc-gateway 里注册 API。

rk-boot 介绍

rk-boot 是一个可通过 YAML 启动多种 Web 服务的框架。

有点类似于 Spring boot。通过集成 rk-xxx 系列库，可以启动多种 Web 框架。当然，用户也可以自定义 rk-xxx 库集成到 rk-boot 中。

rk-boot 亮点

• 通过同样格式的 YAML 文件，启动不同 Web 框架。
• 即使是不同框架，统一日志，Metrics, Tracing 等格式
• 用户可以通过实现 rkentry.Entry 来自定义 YAML 文件。

rk-boot 支持的 Web 框架

欢迎贡献新的 Web 框架到 rk-boot 系列中。

参考 docs & rk-gin 作为例子。

框架	开发状态	安装	依赖
Gin	Stable	go get github.com/rookie-ninja/rk-boot/gin	rk-gin
gRPC	Stable	go get github.com/rookie-ninja/rk-boot/grpc	rk-grpc
Echo	Stable	go get github.com/rookie-ninja/rk-boot/echo	rk-echo
GoFrame	Stable	go get github.com/rookie-ninja/rk-boot/gf	rk-gf
Fiber	Testing	go get github.com/rookie-ninja/rk-boot/fiber	rk-fiber
go-zero	Testing	go get github.com/rookie-ninja/rk-boot/zero	rk-zero
GorillaMux	Testing	go get github.com/rookie-ninja/rk-boot/mux	rk-mux
