使用未知密钥麻烦解组嵌套的json [英] Trouble unmarshalling nested json with unknown keys

问题描述

我在将以下格式的json数据解组到结构时遇到麻烦. json的结构对我来说有点令人困惑，因此对我为取消封送而做的所有愚蠢的事情表示歉意.

I am having trouble unmarshalling a json data of the below format to a struct. The structure of the json looks a bit confusing to me, so apologies for all the dumb things I am doing to unmarshal it.

{
  "message": {
    "Server1.example.com": [
      {
        "application": "Apache", 
        "host": {
          "name": "/^Server-[13456]/"
        }, 
        "owner": "User1", 
        "project": "Web", 
        "subowner": "User2"
      }
    ], 
    "Server2.example.com": [
      {
        "application": "Mysql", 
        "host": {
          "name": "/^Server[23456]/"
        }, 
        "owner": "User2", 
        "project": "DB", 
        "subowner": "User3"
      }
    ] 
  }, 
  "response_ms": 659, 
  "success": true
}

我正在尝试使用以下结构对其进行解组.

I am trying to unmarshal it using the following struct.

type ServerDetails struct  {
  Message  struct{
    Hostname struct{
      Details struct{
        Application string `json:"application"`
        }`json:"-"`
       }`json:"-"`
     }`json:"message"`
}

字段Server[0-9].example.com在生成时将是未知的，并且会发生变化，并且存在此字段

The fields Server[0-9].example.com will be unknown at the time of generating, and will change, and there is this field

      {
    "application": "Apache", 
    "host": {
      "name": "/^Server-[13456]/"
    },

紧跟在没有外部密钥的服务器名称之后，这再次让我感到困惑.我尝试了很多组合以了解如何将其解组，但是我失败了.

just after the server name that doesn't have a key outside, which again looks confusing to me. I tried a good number of combinations to understand how this could be unmarshalled, but I failed.

什么是使json字段解组为结构的有效方法?

What is a working approach to get the json fields unmarshal into a struct?

推荐答案

您可以包含map [string] ServerStruct来满足您的要求.

You could include a map[string]ServerStruct to fullfill your requirements.

您的结构可能看起来像这样:

your struct could look like this:

type YourStruct struct {
    Success bool
    ResponseMS int
    Servers map[string]*ServerStruct
}

type ServerStruct struct {
    Application string
    Owner string
    [...]
}

使用一些其他json标签，您将能够解析json.

With some additional json tags, you will be able to parse your json.
