如何在golang中的字符串(JSON格式)中转义字符

What is the idiomatic way to escape only the characters in a string require to be escaped by the JSON specification.

(I am not trying to marshal/unmarshal an object or string, I just want to escape the characters inside a string.

This works, but surely there is a more idiomatic way? https://play.golang.org/p/rcHZbrjFyyH

func main() {
    fmt.Println(jsonEscape(`dog "fish" cat`))
    //output: dog \"fish\" cat
}

func jsonEscape(i string) string {
    b, err := json.Marshal(i)
    if err != nil {
        panic(err)
    }
    // Trim the beginning and trailing " character
    return string(b[1:len(b)-1])
}

    I don't know if using backticks ` is the most idiomatic way to escape characters but is more readable, for example, you could use something like:

    fmt.Println(jsonEscape(`dog "fish" cat`))

    Check the String literals section.
