我目前正在使用GoFiber V2创建golang api。
我在Mongo数据库中有以下音乐轨道的文档结构:

目前我有以下结构体的轨道在我的Golang模型:
type Track struct {
ID primitive.ObjectID `bson:"_id, omitempty" json:"_id"`
TrackTitle string `bson:"track_title" json:"track_title"`
ArtistId string `bson:"artist_id" json:"artist_id"`
ArtistName string `bson:"artist_name" json:"artist_name"`
AlbumTitle string `bson:"album_title" json:"album_title"`
Composer string `bson:"composer" json:"composer"`
Publisher string `bson:"publisher" json:"publisher"`
Description string `bson:"description" json:"description"`
Duration string `bson:"duration" json:"duration"`
UrlPath string `bson:"url_path" json:"url_path"`
VocalType string `bson:"vocal_type" json:"vocal_type"`
BeatsPerMinute string `bson:"beats_per_minute" json:"beats_per_minute"`
FilePathCompressed string `bson:"file_path_compressed" json:"bfile_path_compressed"`
FilePathUncompressed string `bson:"file_path_uncompressed" json:"file_path_uncompressed"`
PreviewURL string `bson:"preview_url" json:"preview_url"`
Genres []interface{} `bson:"genres" json:"genres"`
GenresKeys []interface{} `bson:"genres_keys" json:"genres_keys"`
Moods []interface{} `bson:"moods" json:"moods"`
Styles []interface{} `bson:"styles" json:"styles"`
Instruments []interface{} `bson:"instruments" json:"instruments"`
Keywords []interface{} `bson:"keywords" json:"keywords"`
SoundsLike []interface{} `bson:"sounds_like" json:"sounds_like"`
ResemblesSong []interface{} `bson:"resembles_song" json:"resembles_song"`
LastModified int `bson:"last_modified" json:"last_modified"`
VariationCount int `bson:"variation_count" json:"variation_count"`
}
目前所有的文档字段都被正确地解码为JSON，但是我现在在如何构造嵌入的"变量"上陷入了僵局。字段(注意变量中有变量)。嵌入变量的结构是一个没有键的对象，而是一个动态的mongo ID字符串。
我已经尝试实现自定义结构和接口类型，但无济于事。
如果有人以前遇到过这个问题，请提供任何帮助。
我建议尽可能避免使用interface{}(或any)，使用具体类型。例如:genres是字符串数组，Go中使用[]string。
对于variations.variations字段，您可以使用map,string键和描述其元素的结构类型。
