gow

gow is a golang HTTP web framework

gow logo

借鉴和参考的项目：gin/beego/mux

项目地址

https://github.com/zituocn/gow

特性

  • 类 gin 的 Context 封装、路由分组和 middleware，可快速入门
  • 使用 regexp 实现路由完全匹配，支持大小写忽略
  • 统一的配置入口(ini格式)，也可实现自己喜欢的配置方式
  • 支持服务器端渲染HTML页面，可自由扩展HTML模板函数
  • 可以自由选择封装在lib的sdk，如 mysql redis nsq rpc mem-cache oauth pay 等

1. 快速开始

# 创建一个hello的项目
mkdir hello

cd hello

# 使用go mod
go mod init

# 安装gow

go get github.com/zituocn/gow
1.1 创建 main.go
package main

import (
	"github.com/zituocn/gow"
)

func main() {
	r := gow.Default()

	r.GET("/", func(c *gow.Context) {
		c.JSON(gow.H{
			"code": 0,
			"msg":  "success",
		})
	})

	//default :8080
	r.Run()
}

也可以写成这样

package main

import (
	"github.com/zituocn/gow"
)

func main() {
	r := gow.Default()
	r.GET("/", IndexHandler)
	//default :8080
	r.Run()
}

// IndexHandler response h
func IndexHandler(c *gow.Context) {
	h := map[string]interface{}{
		"project": "gow",
		"website": "https://github.com/zituocn/gow",
	}
	c.JSON(h)
}

自定义method，使用 r.Handle

package main

import "github.com/zituocn/gow"

func main() {
	r := gow.Default()
	r.Handle("GET,POST", "/", func(c *gow.Context) {
		c.String("index")
	})
}
1.2 运行
go run main.go

运行结果

Listening and serving HTTP on http://127.0.0.1:8080
1.3 访问

curl访问

curl -i http://127.0.0.1:8080
