Golang的一堆代码（GoCH, Code Heap for Golang）

安装

go get -u gitee.com/gaodongchen/goch

使用

import "gitee.com/gaodongchen/goch"

type User struct {
    CreatedAt goch.Time `json:"created_at"`
}

user := &User{CreatedAt: goch.Now()}
data, _ :=json.Marshal(user)
fmt.Println(string(data))

输出：

{"created_at": "2006-01-02 15:04:05"}
