要点

1. 显示变量类型：%T
2. 码流十六进制串：%x or %X

代码示例

package main

import (
    "fmt"
)

/*
The type of data is []uint8
a= 48656c6c6f
b= 48656C6C6F
c= Hello
*/
func main() {
    data := []byte{'H', 'e', 'l', 'l', 'o'}
    fmt.Printf("The type of data is %T\n", data)
    a := fmt.Sprintf("%x", data)
    b := fmt.Sprintf("%X", data)
    c := string(data)
    fmt.Println("a=", a)
    fmt.Println("b=", b)
    fmt.Println("c=", c)
}
