取消编组时跳过解码Unicode字符串：golang

I have this JSON:

{
    "code":"\u5728\u4e30\u5fb7\u5c14Berro\u8212\u9002\u76841\u623f\u5355\u4f4d"
}

And this struct

type Text struct {
    Code string
}

If I use any of the json.Unmarshal or NewDecoder.Decode, the Unicode is converted to the actual Chinese. So Text.Code is

I don't want it to convert, I want the same unicode string.

You can do this with custom decoder https://play.golang.org/p/H-gagzJGPI

package main

import (
    "encoding/json"
    "fmt"
)

type RawUnicodeString string

func (this *RawUnicodeString) UnmarshalJSON(b []byte) error {
    *this = RawUnicodeString(b)
    return nil
}

func (this RawUnicodeString) MarshalJSON() ([]byte, error) {
    return []byte(this), nil
}

type Message struct {
    Code RawUnicodeString
}

func main() {
    var r Message
    data := `{"code":"\u5728\u4e30\u5fb7\u5c14Berro\u8212\u9002\u76841\u623f\u5355\u4f4d"}`
    json.Unmarshal([]byte(data), &r)
    fmt.Println(r.Code)
    out, _ := json.Marshal(r)
    fmt.Println(string(out))
}

You could use json.RawMessage instead of string. https://play.golang.org/p/YcY2KrkaIb

    package main

    import (
        "encoding/json"
        "fmt"
    )

    type Text struct {
        Code json.RawMessage
    }

    func main() {
        data := []byte(`{"code":"\u5728\u4e30\u5fb7\u5c14Berro\u8212\u9002\u76841\u623f\u5355\u4f4d"}`)
        var message Text
        json.Unmarshal(data, &message)
        fmt.Println(string(message.Code))
    }

Simple solution is to escape your backslash by preceding it with another backslash.

func main() {
    var jsonRawOriginal json.RawMessage = []byte(`"\u5728\u4e30\u5fb7\u5c14Berro\u8212\u9002\u76841\u623f\u5355\u4f4d"`)
    var jsonRawEscaped json.RawMessage = []byte(strings.Replace(string(jsonRawOriginal), `\u`, `\\u`, -1))

    fmt.Println(string(jsonRawOriginal)) // "\u5728\u4e30\u5fb7\u5c14Berro\u8212\u9002\u76841\u623f\u5355\u4f4d"
    fmt.Println(string(jsonRawEscaped))  // "\\u5728\\u4e30\\u5fb7\\u5c14Berro\\u8212\\u9002\\u76841\\u623f\\u5355\\u4f4d"

    var a interface{}
    var b interface{}

    json.Unmarshal(jsonRawOriginal, &a)
    json.Unmarshal(jsonRawEscaped, &b)

    fmt.Println(a) // 在丰德尔Berro舒适的1房单位
    fmt.Println(b) // \u5728\u4e30\u5fb7\u5c14Berro\u8212\u9002\u76841\u623f\u5355\u4f4d
