## Beego框架特点 ##

*  比较典型的MVC框架
 *  中国人开发，文档比较详细
 *  使用的公司多，如今日头条、百度云盘、腾讯、阿里
 *  例子很多

## Beego 依赖包安装 ##

go get -u github.com/astaxie/beego
    go get -u github.com/beego/bee
    go get github.com/astaxie/beego/orm

## Beego之controller ##

### Beego支持三种路由 ###

*  固定路由
 *  正则路由

## Beego 建表程序 ##

package main
    
    import (
    	"fmt"
    	"github.com/astaxie/beego/orm"
    )
    
    import _ "github.com/go-sql-driver/mysql" // import your used driver
    
    type User struct {
    	Id   int
    	Name string `orm:"size(32)"`
    }
    
    func init() {
    	orm.RegisterDataBase("default", "mysql", "root:123456@tcp(127.0.0.1:3306)/school?charset=utf8", 30)
    	orm.RegisterModel(new(User))
    	orm.RunSyncdb("default", false, true)
    }
    
    func main() {
    
    	o := orm.NewOrm()
    
    	user := User{Name: "BeyondChampion"}
    
    	// insert
    	id, err := o.Insert(&user)
    	fmt.Printf("ID: %d, ERR: %v\n", id, err)
    	
    }

## Beego 增删改查 ##

package main
    
    import (
    	"fmt"
    	"github.com/astaxie/beego/orm"
    	_ "github.com/go-sql-driver/mysql" // import your used driver
    )
    
    // Model Struct
    type User struct {
    	Id   int
    	Name string `orm:"size(32)"`
    }
    
    func init() {
    	orm.RegisterDataBase("default", "mysql", "root:123456@tcp(127.0.0.1:3306)/school?charset=utf8", 30)
    	orm.RegisterModel(new(User))
    	orm.RunSyncdb("default", false, true)
    }
    
    func main() {
    	o := orm.NewOrm()
    
    	user := User{Name: "ArthurGuo"}
    
    	// insert
    	id, err := o.Insert(&user)
    	fmt.Printf("ID: %d, ERR: %v\n", id, err)
    
    	// update
    	user.Name = "Guo"
    	num, err := o.Update(&user)
    	fmt.Printf("NUM: %d, ERR: %v\n", num, err)
    
    	u := User{Id: user.Id}
    	err = o.Read(&u)
    	fmt.Printf("ERR: %v\n", err)
    
    	//num, err = o.Delete(&u)
    	//fmt.Printf("NUM: %d, ERR: %v\n", 1, err)
    }
