英文:
How to add multiple groups to gin routing for api version inheritance?
问题
我目前正在使用Go + Gin开发一个API。
API应该包括一个版本字符串，例如字符串v1
http://127.0.0.1:3000/v1/user/get_username
这没有问题，因为我可以使用Gin创建一个组
v1 := router.Group("/v1")v1.GET("/user/get_username", modules.UserGetUsername)
但是...如果我启动一个新的API版本"v2"，并且函数UserGetUsername中的代码没有改变，我必须执行以下操作
v1 := router.Group("/v1")v1.GET("/user/get_username", modules.UserGetUsername)v2 := router.Group("/v2")v2.GET("/user/get_username", modules.UserGetUsername)
有没有更好的解决方案 - 也许像这样：
v1_v2 := router.Group("/v1").AnotherGroup("/v2")v1_v2.GET("/user/get_username", modules.UserGetUsername)
谢谢你的建议。

I'm currently working on a API with Go + Gin.
The API should include a version string, for example the string v1
http://127.0.0.1:3000/v1/user/get_username
That is no problem, because I can create a group with Gin
v1 := router.Group("/v1")v1.GET("/user/get_username", modules.UserGetUsername)
But... if I start a new API-Version "v2" and the code within the function UserGetUsername didn't changed I must do the following
v1 := router.Group("/v1")v1.GET("/user/get_username", modules.UserGetUsername)v2 := router.Group("/v2")v2.GET("/user/get_username", modules.UserGetUsername)
Is there a nicer solution for that - maybe something like that:
v1_v2 := router.Group("/v1").AnotherGroup("/v2")v1_v2.GET("/user/get_username", modules.UserGetUsername)
Thank you for your suggestions.

我不认为Gin提供这个功能，但编写起来很容易。
type GroupGroup struct {groups []*gin.RouterGroup}func NewGroupGroup(groups []*gin.RouterGroup) GroupGroup {return GroupGroup {groups,}}func (g *GroupGroup) handle(method string, path string, handler gin.HandlerFunc) {for _, group := range g.groups {group.Handle(method, path, handler)}}
然后，你可以这样使用：
v1 := router.Group("/v1")v2 := router.Group("/v2")g := NewGroupGroup([]*gin.RouterGroup { v1, v2 })g.handle(http.MethodGet, "hello", sayHello)g.handle(http.MethodPost, "goodbye", sayGoodbye)
英文:
I don’t think Gin provides this, but it looks easy to write.
type GroupGroup struct {groups []*gin.RouterGroup}func NewGroupGroup(groups []*gin.RouterGroup) GroupGroup {return GroupGroup {groups,}}func (g *GroupGroup) handle(method string, path string, handler gin.HandlerFunc) {for _, group := range g.groups {group.Handle(method, path, handler)}}
Then, you can use it like so :
v1 := router.Group("/v1")v2 := router.Group("/v2")g := NewGroupGroup([]*gin.RouterGroup { v1, v2 })g.handle(http.MethodGet, "hello", sayHello)g.handle(http.MethodPost, "goodbye", sayGoodbye)
