拆封巢JSON响应到嵌套结构

     ], 
     "secondaryDescription": "" 
     } 
    }, 
    "basicAttack": { 
     "itemDescription": {

以下是我解组JSON响应转换结构体数组：

var gods []God 
json.Unmarshal(jsonResponse, &gods) 
return gods 

一切除abilityDescription1(2,3,4,5)和everythi正确编组在该结构中。

有什么建议吗？

使用结构标签将JSON字段名称映射到结构字段名称。

许多结构字段都是小写字母，因此未导出，这意味着encoding/json软件包不能访问/编入它们。看看http://golang.org/pkg/reflect/#StructTag（JSON包将与“说明”匹配“描述”，尽管 - 即小写字母已经匹配）

您也更好（为了可读性/添加标签的能力）将您的构成单独的项目，然后嵌入它们。您有重复Rank_items的情况，而您可以定义一次，然后根据需要嵌入它：

例如，

Basic_attack struct { 
     ItemDescription ItemDesc `json:"itemDescription"` 
     Menu []MenuItems `json:"menuitems"` 
     Rank []RankItems `json:"rankitems"` 
    } 

    ItemDesc struct { 
     Cooldown string `json:"cooldown"` 
     Cost  string `json:"cost"` 
     Description string `json:"description"` 
     Menu  []MenuItems `json:"menuitems"` 
     ... 
    } 

    MenuItems struct { 
      Description string 
      Value  string 
    } 

    RankItems struct { 
       Description string 
       Value  string 
    }
