Golang : Escaping single quotes

Question

Is there a way to escape single quotes in go?

The following:

str := "I'm Bob, and I'm 25."
str = strings.Replace(str, "'", "\'", -1)

Gives the error: unknown escape sequence: '

I would like str to be

"I\'m Bob, and I\'m 25."

Solution 1

You need to ALSO escape the slash in strings.Replace.

str := "I'm Bob, and I'm 25."
str = strings.ReplaceAll(str, "'", "\\'")

Solution 2

+to @KeylorSanchez answer: your can wrap replace string in back-ticks:

strings.ReplaceAll(str, "'", `\'`)

Solution 3

// addslashes()
func Addslashes(str string) string {
    var buf bytes.Buffer
    for _, char := range str {
        switch char {
        case '\'':
            buf.WriteRune('\\')
        }
        buf.WriteRune(char)
    }
    return buf.String()
}

Even the first string can be in backquote. In my case i had to replace \" with " in my dbjson variable dbjson = strings.Replace(dbjson, `\"`, `"`, -1) This answer helped me to get there :)

Probably best to use var buf strings.Builder (instead of bytes.Buffer) in this case. It has the same methods, so no other changes needed
