有时JSON有时会对象数组 [英] JSON sometimes array sometimes object

问题描述

我创建了一个结构来取消对json响应的解组，并且还有一个对象，它的效果很好。但是，在json响应包含对象数组的情况下，显然解组失败。如何在Go中处理这种情况？

 单个回应：
 {
净： {
comment：{
line：{
$：这个空间是静态分配的，
@number：0
 
 
 
 
 
 $ b数组响应：
 {
净：{
 评论：{
line：[
 {
$：所有滥用问题只会受到滥用的回应，
@number： 0
}，
 {
$：通过手柄ABUSE223-ARIN上的联系信息进行团队合作，
@number：1
} 
] 
} 
} 
} 
  

我想过创建2个版本的结构，然后以某种方式确定我返回的实例，但这种感觉很浪费。我也尝试unmarshalling到地图[字符串]实例{}，但我有点失落，不知道我是否正在走向正确的道路。

任何建议感谢。

解决方案

你有没有尝试unmarshall进入map [string] interface {}？

 类型网络结构{
 Comment map [string] interface {}`json：comment`
} 
  

然后评论[行]值可能是数组或对象。

I am consuming an API who's response for a particular field is sometimes and object and sometimes and array of object.

I created a struct to unmarshall the json response and it works great. However, in the instances where the json response has an array of objects, obviously the unmarshalling fails. How can I deal with this situation in Go?

Single Response:
{
    "net": {
                "comment": {
                    "line": {
                        "$": "This space is statically assigned",
                        "@number": "0"
                    }
                }
            }
}


Array Response:
{
    "net": {
                "comment": {
                    "line": [
                        {
                            "$": "All abuse issues will only be responded to by the Abuse",
                            "@number": "0"
                        },
                        {
                            "$": "Team through the contact info found on handle ABUSE223-ARIN",
                            "@number": "1"
                        }
                    ]
                }
            }
}

I thought about creating 2 versions of the struct and then somehow determining which instance I got back, but this feels quite wasteful. I have also tried unmarshalling into map[string]instance{} but I got a bit lost and wasn't sure if I was headed down the right path.

Any advice would be appreciated.

解决方案

Have you tried unmarshall into map[string]interface{}?

    type Net struct{
        Comment map[string]interface{} `json:"comment"`
    }

Then Comment["line"] value is possible array or object.
