将符文转换成字符串

Question

I am trying to convert s := '{"selector:"{"Status":"open"}"}' to type string, as I need to pass this as an argument to a query using GetQueryResult().

I have tried UnescapeString, it only accepts string as argument:

fmt.Println("args " ,html.UnescapeString(s)

but s is a Go rune.

Answer 1

The Go Programming Language Specification

String literals

Rune literals

---

Use string raw literal back quotes, not rune literal single quotes.

---

For example,

package main

import (
    "fmt"
)

func main() {
    s := `{"selector:"{"Status":"open"}"}`
    fmt.Printf("type %T: %s", s, s)
}

Playground: https://play.golang.org/p/lGARb35VHTv

Output:

type string: {"selector:"{"Status":"open"}"}
