How to add language prefix in url in Gin?

Question

I want to add language prefix in url like localhost/en/someurl or localhost/de/someurl. I found this solution:

en := r.Group("/en")
{
    en.GET("/someurl", ...)
    ...
}
de := r.Group("/de")
{
    de.GET("/someurl", ...)
    ...
}

but it requires to repeat all routers and add new language will require another duplication. Can I avoid it with Gin?

Answer 1

How about using a path parameter instead?

r.Get("/:lang/someurl", ...)

In the handler you can then access the language:

func(c *gin.Context) {
    lang := c.Param("lang")

    // ...
}
