How to prevent Fiber from auto registerting HEAD routes?
问题
Fiber v2（https://gofiber.io/）会自动为每个GET路由添加一个HEAD路由。
有没有办法阻止这个行为？
我只想注册GET路由。实际上，我只想注册我明确添加的那些路由。
这个能做到吗？
英文:
Fiber v2 (https://gofiber.io/) automatically adds a HEAD route for each GET route.
Is it possible to prevent this?
I want only the GETs to be registered. Actually, I want to register only those routes I add explicitly.
Is it possible to do this?

查看(*App).Get的实现：
// Get为GET方法注册一个路由，该方法请求指定资源的表示形式。使用GET的请求应仅检索数据。
func (app *App) Get(path string, handlers ...Handler) Router {
return app.Head(path, handlers...).Add(MethodGet, path, handlers...)
}
以及(*Group).Get的实现：
// Get为GET方法注册一个路由，该方法请求指定资源的表示形式。使用GET的请求应仅检索数据。
func (grp *Group) Get(path string, handlers ...Handler) Router {
grp.Add(MethodHead, path, handlers...)
return grp.Add(MethodGet, path, handlers...)
}
无法阻止这种行为。您只能避免使用它们，并直接使用Add方法。例如，像这样注册一个GET路由：
app.Add(fiber.MethodGet, "/", func(c *fiber.Ctx) error {
return c.SendString("Hello, World!")
})
请注意，(*App).Use和(*Group).Use匹配所有HTTP动词。您可以像这样删除HEAD方法：
methods := make([]string, 0, len(fiber.DefaultMethods)-1)
for _, m := range fiber.DefaultMethods {
if m != fiber.MethodHead {
methods = append(methods, m)
}
}
app := fiber.New(fiber.Config{
RequestMethods: methods,
})
注意：每当注册一个HEAD路由时，它会引发panic，因为它不包含在RequestMethods中。
我不知道您为什么要这样做。也许更好的选择是使用一个中间件来拒绝所有的HEAD请求，像这样：
app.Use(func(c *fiber.Ctx) error {
if c.Method() == fiber.MethodHead {
c.Status(fiber.StatusMethodNotAllowed)
return nil
}
return c.Next()
})
英文:
See the implementation of (*App).Get:
// Get registers a route for GET methods that requests a representation
// of the specified resource. Requests using GET should only retrieve data.
func (app *App) Get(path string, handlers ...Handler) Router {
return app.Head(path, handlers...).Add(MethodGet, path, handlers...)
}
And (*Group).Get:
// Get registers a route for GET methods that requests a representation
// of the specified resource. Requests using GET should only retrieve data.
func (grp *Group) Get(path string, handlers ...Handler) Router {
grp.Add(MethodHead, path, handlers...)
return grp.Add(MethodGet, path, handlers...)
}
There is no way to prevent this behavior. All you can do is to avoid using them and use the Add method directly. For example, register a GET route like this:
app.Add(fiber.MethodGet, "/", func(c *fiber.Ctx) error {
return c.SendString("Hello, World!")
})
Please note that (*App).Use and (*Group).Use match all HTTP verbs. You can remove the HEAD method like this:
methods := make([]string, 0, len(fiber.DefaultMethods)-1)
for _, m := range fiber.DefaultMethods {
if m != fiber.MethodHead {
methods = append(methods, m)
}
}
app := fiber.New(fiber.Config{
RequestMethods: methods,
})
Note: it panics whenever a HEAD route is registered since it's not included in RequestMethods.
I don't know why you want to do this. Maybe a better choice is to use a middleware to reject all HEAD requests like this:
app.Use(func(c *fiber.Ctx) error {
if c.Method() == fiber.MethodHead {
c.Status(fiber.StatusMethodNotAllowed)
return nil
}
return c.Next()
})
