import ( "encoding/json" "fmt" ) 定义一个 map: go myMap := map[string]interface{}{ "name": "Alice", "age": 30, "city": "New York", "isStudent": false, } 使用json.Marshal 将map 转换为 JSON 字符串: go jsonData, err := json.Marshal(myMap) if err != nil { fmt.Print...

通过JSON 进行转换 先将map转换成JSON,再通过 JSON 转换成struct 操作有点繁琐 func TestMapToStructByJson(t *testing.T) { beforeMap := map[string]interface {}{ "id":"123", "user_name":"酒窝猪", "address":[]map[string]interface{}{{"address": "address01"}, {"address": "address02"}...
