go json解析问题 大牛们帮帮忙

```go package main import ( "encoding/json" "fmt" ) //定义结构体 type Animal struct { Code int `json:"code"` Data smmsData `json:"data"` Subcode int `json:"subcode"` } type smmsData struct { Song smmsong `json:"song"` } type smmsong struct { Count int `json:"count"` Itemlist ltemlistong `json:"itemlist"` Name string `json:"name"` Order int `json:"order"` Type int `json:"type"` } type ltemlistong []struct { Albummid string `json:"albummid"` Docid string `json:"docid"` Id string `json:"id"` Mid string `json:"mid"` Name string `json:"name"` Singer string `json:"singer"` } func main() { //建立json jsonBlob := `{ "code":0, "data":{ "song":{ "count":2, "itemlist":[{ "albummid":"001ZaCQY2OxVMg", "docid":"4960718353595419009", "id":"108041208", "mid":"000lH7Do3X6Aot", "name":"雪阳", "singer":"鹿予" },{ "albummid":"001ZaCQY2OxVMg", "docid":"4277524965976373789", "id":"107195477", "mid":"0004snbm3ZMeFz", "name":"雪阳花", "singer":"林爽"}], "name":"单曲", "order":0, "type":1}}, "subcode":0 }` var animals Animal //定义结构体 json.Unmarshal([]byte(jsonBlob), &animals) //json解析 //打印数据 fmt.Println(animals.Code) fmt.Println(animals.Data) fmt.Println(animals.Data.Song.Count) //遍历itemlist里的数据 for _, k := range animals.Data.Song.Itemlist { fmt.Println(k.Albummid) fmt.Println(k.Docid) fmt.Println(k.Id) fmt.Println(k.Mid) fmt.Println(k.Name) fmt.Println(k.Singer) } //打印数据 fmt.Println(animals.Data.Song.Name) fmt.Println(animals.Data.Song.Order) fmt.Println(animals.Data.Song.Type) } ```

看看你结构体怎么定义的

你这全是小写的，首字母请大写，golang是支持嵌套的
