将JSON成员字符串转换为JSON对象

问题描述：

I have this struct:

type ResponseStatus struct {
    StatusCode int
    Message    string
    Data       string `json:"data"`
}

type Pets struct {
    Id   int    `json:"id"`
    Name string `json:"name"`
    Age  int    `json:"age"`
    Type string `json:"type"`
}

and this is my json result:

{
    "StatusCode": 200,
    "Message": "Hello framework - OK",
    "data": "[{\"id\":1,\"name\":\"george\",\"age\":2,\"type\":\"dog\"},{\"id\":2,\"name\":\"walter\",\"age\":1,\"type\":\"rabbit\"},{\"id\":3,\"name\":\"tom\",\"age\":1,\"type\":\"cat\"},{\"id\":4,\"name\":\"doggo\",\"age\":5,\"type\":\"dog\"},{\"id\":5,\"name\":\"torto\",\"age\":3,\"type\":\"turtle\"},{\"id\":6,\"name\":\"jerry\",\"age\":1,\"type\":\"hamster\"},{\"id\":7,\"name\":\"garf\",\"age\":2,\"type\":\"cat\"},{\"id\":8,\"name\":\"milo\",\"age\":4,\"type\":\"dog\"},{\"id\":9,\"name\":\"kimi\",\"age\":2,\"type\":\"cat\"},{\"id\":10,\"name\":\"buck\",\"age\":1,\"type\":\"rabbit\"}]"
}

How can I escaped double quotes in my result data as JSON like this:

{
  "StatusCode": 200,
  "Message": "Hello framework - OK",
  "data": [
    {"id": 1,"name": "george","age": 2,"type": "dog"},
    {"id": 2,"name": "walter","age": 1,"type": "rabbit"},
    {"id": 3,"name": "tom","age": 1,"type": "cat"},
    {"id": 4,"name": "doggo","age": 5,"type": "dog"},
    {"id": 5,"name": "torto","age": 3,"type": "turtle"},
    {"id": 6,"name": "jerry","age": 1,"type": "hamster"},
    {"id": 7,"name": "garf","age": 2,"type": "cat"},
    {"id": 8,"name": "milo","age": 4,"type": "dog"},
    {"id": 9,"name": "kimi","age": 2,"type": "cat"},
    {"id": 10,"name": "buck","age": 1,"type": "rabbit"}
  ]
}

我有以下结构： p>

  type ResponseStatus结构{\  n StatusCode int 
消息字符串
数据字符串`json：“ data”`
} 
 
type Pets结构{
 ID int`json：“ id”`
名称字符串`json：“ name”  
 Age int`json：“ age”`
输入字符串`json：“ type”`
} 
  code>  pre> 
 
 ，这是我的json结果： 
 
 
  {
“ StatusCode”：200，
“ Message”：“ Hello framework-OK”，
“ data”：“ [{\” id \“：  1，\ “名称\”：\ “乔治·\”，\ “年龄\”：2，\ “类型\”：\ “狗\”}，{\ “ID \”：2，\ “名称\”：  \ “沃尔特\”，\ “年龄\”：1，\ “类型\”：\ “兔\”}，{\ “ID \”：3，\ “名称\”：\ “汤姆\”，\” 年龄\ “：1，\” 类型\ “：\” 猫\ “}，{\” ID \ “：4，\” 名称\ “：\” 声张\ “\ ”年龄\“：5，\” 类型\ “：\” 狗\ “}，{\” ID \ “：5，\” 名称\ “：\” 托特\ “\ ”年龄\“：3，\ ”类型\“：\” 龟\  “}，{\” ID \ “：6，\” 名称\ “：\” 杰里\ “\ ”年龄\“：1，\ ”类型\“：\ ”仓鼠\“}，{\” ID \  “：7，\” 名称\ “：\” garf \ “\ ”年龄\“：2，\ ”类型\“：\ ”猫\“}，{\ ”ID \“：8，\” 名\  “：\” 米洛\”，\ “年龄\”：4，\ “类型\”：\ “狗\”}，{\ “ID \”：9，\ “名称\”：\ “基米\”，  \ “年龄\”：2，\“TY  PE \ “：\” 猫\ “}，{\” ID \ “：10，\” 名称\ “：\” 巴克\ “\ ”年龄\“：1，\ ”类型\“：\” 兔\  “}]” 
} 
  code>  pre> 
 
 如何像这样将JSON中的结果数据转义为双引号： p> 
 
 
   {
“ StatusCode”：200，
“ Message”：“ Hello framework-OK”，
“ data”：[
 {“ id”：1，“ name”：“ george”，“  age“：2，” type“：” dog“}，
 {” id“：2，” name“：”沃尔特“，” age“：1，” type“：”兔子“}，
 {”  id“：3，” name“：” tom“，” age“：1，” type“：” cat“}，
 {” id“：4，” name“：” doggo“，” age“：5  ，“ type”：“ dog”}，
 {“ id”：5，“ name”：“ torto”，“ age”：3，“ type”：“ turtle”}，
 {“ id”：6  ，“ name”：“ jerry”，“ age”：1，“ type”：“仓鼠”}，
 {“ id”：7，“ name”：“ garf”，“ age”：2，“ type”  ：“ cat”}，
 {“ id”：8，“ name”：“ milo”，“ age”：4，“ type”：“ dog”}，
 {“ id”：9，“ name”  ：“ kimi”，“ age”：2，“ type”：“ cat”}，
 {“ id”：10，“ name”：“ buck”，“ age”：1，“ type”：“兔子”  } 
] 
} 
  code>  pre> 
  div>

You are doing fine, just a few remarks: Remove the quote before and after the square brackets, and you should make Data of type []Pets (which struct I would call Pet, because every item contains a single Pet). The square-brackets are part of the JSON construct. And then you don't need to escape the quotes, because they become JSON identifiers.

In your way, it becomes a single long string, which, clearly, is not what you intent to have.

These are the structures that fit on your second JSON

type ResponseStatus struct {
   StatusCode int    
   Message    string 
   Data       []Pet  `json:"data"`
}

type Pet struct {
   Id   int    `json:"id"`
   Name string `json:"name"`
   Age  int    `json:"age"`
   Type string `json:"type"`
}
