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...

在Golang 中,字节和字符串之间的转换非常容易。使用string()和[]byte()函数可以轻松地在这两种数据类型之间进行转换。同时,由于 Golang 提供了标准库中的encoding/hex包,所以将字节数组转换为十六进制字符串和将十六进制字符串转换为字节数组也很方便。
