strconv.Quote() in Golang can be used to convert a string to a hexadecimal representation. However, strconv.Quote() adds quotes around the string in addition to escaping any special characters. To remove the quotes and get only the hexadecimal representation, you can use the strconv.Unquote() function. Here is an example:
package main
import (
"fmt"
"strconv"
)
func main() {
str := "Hello, World!"
hex := strconv.QuoteToASCII(str)[1 : len(strconv.QuoteToASCII(str))-1]
unquotedHex, _ := strconv.Unquote(hex)
fmt.Println(unquotedHex)
}
In this example, strconv.QuoteToASCII() is used to convert the string to a quoted string with any special characters escaped. The [1:len(strconv.QuoteToASCII(str))-1] is used to remove the quotes around the string. Finally, strconv.Unquote() is used to unquote the string and obtain the actual hexadecimal representation.
The output of the above code will be:
