GoFrame通用类型变量gvar与interface基本使用对比

package main
import (
   "fmt"
   "github.com/gogf/gf/container/gvar"
   "github.com/gogf/gf/frame/g"
)
func main() {
   var v g.Var
   v.Set("123")
   fmt.Printf("v的类型：%T  值：%v \n", v, v) //v的类型：gvar.Var  值：{123 false}  其中false指的是并发安全开关为false
   //设置并发安全开关为true
   var vSafe = gvar.New("123", true)
   fmt.Printf("vSafe的类型：%T  值：%v \n", vSafe, vSafe) //vSafe的类型：*gvar.Var  值：123
   fmt.Println("获取gvar的值：", v.Val()) //123
   //基本类型转换
   fmt.Printf("v.Int()转换后的类型：%T  值：%v \n", v.Int(), v.Int())
   fmt.Printf("v.Float64()转换后的类型：%T  值：%v \n", v.Float64(), v.Float64())
   fmt.Printf("v.Uint()转换后的类型：%T  值：%v \n", v.Uint(), v.Uint())
   //切片类型转换
   fmt.Printf("v.Ints()转换后的类型：%T  值：%v \n", v.Ints(), v.Ints())
   fmt.Printf("v.Strings()转换后的类型：%T  值：%v \n", v.Strings(), v.Strings())
   fmt.Printf("v.Floats()转换后的类型：%T  值：%v \n", v.Floats(), v.Floats())
}

   }
   res, _ := json.Marshal(p)

   fmt.Println("反序列化结果：", p1) //反序列化结果： &{王中阳 12 ["吃饭","睡觉","打豆豆"]}
}
