以下是我如何将JSON响应解组到struct数组中：
var gods []God
json.Unmarshal(jsonResponse, &gods)
return gods
除了abilityDescription1(2,3,4,5)以及该结构中的所有内容外，所有内容都正确编组。
有什么建议吗？
答案 0 :(得分：1)
使用struct标签将JSON字段名称映射到struct字段名称。
您的许多结构字段都是小写的，因此未导出，这意味着encoding / json包无法访问/编组。看看http://golang.org/pkg/reflect/#StructTag（JSON包将匹配“描述”和“描述”，但是 - 小写已经匹配）
你也最好（为了可读性/添加标签的能力）将你的结构分成单独的项目，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：
e.g。
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
}
