golang 实现interface{}转其他类型操作_Golang_

 //interface转其他类型————返回值是interface，直接赋值是无法转化的 //interface 转string var a interface{} var str5 string a = "3432423" str5 = a.(string) fmt.Println(str5) //interface 转int var m interface{} var m1 int m = 43 m1 = m.(int) fmt.Println(m1) //interface 转float64 var ff interface{} var ff1 float64 ff = 432.54 ff1 = ff.(float64) fmt.Println(ff1)

 func interface2String(inter interface{}) { switch inter.(type) { case string: fmt.Println("string", inter.(string)) break case int: fmt.Println("int", inter.(int)) break case float64: fmt.Println("float64", inter.(float64)) break } } func main() { interface2String("jack") interface2String(1) interface2String(12.223) }

 string jack int 1 float64 12.223
