在Golang中,十六进制字符串和[]byte之间的转换主要依赖于encoding/hex包提供的hex.DecodeString函数。这个函数能够将一个十六进制字符串解码为字节切片。 编写函数 我们将编写一个函数HexStringToBytes,该函数接受一个十六进制字符串作为输入,并返回对应的[]byte。 go package main import ( "encoding/hex" "fmt" )...

Stringis a nice way to deal with short sequence, of bytes or characters. Everytime you operate on string, such as find replace string or take substring, a new string is created. This is very inefficient if string is huge, such as file content. [seeGolang: String] Byte sliceis just li...

func FileMD5(filePath string) (string, error) { file, err := os.Open(filePath) if err != nil { return "", err } hash := md5.New() _, _ = io.Copy(hash, file) return hex.EncodeToString(hash.Sum(nil)), nil} 经过实际测试发现占用内存几乎非常非常少,这里大家就会发现md5.New()的...
bytes中常用函数的使用: package main; import ( "bytes" "fmt" "unicode" ) //bytes包中实现了大量对[]byte操作的函数和两个最主要的Reader和Buffer两个结构 func main() { str := "aBcD"; //转为小写 fmt.Println(string(bytes.ToLower([]byte golang bytes 转二进制 golang bc ico 分隔符 转...
