🔄 Redirect

The redirect methods are used to redirect the context (request) to a different URL or route.

Redirect Methods​

To​

Redirects to the URL derived from the specified path, with a specified status, a positive integer that corresponds to an HTTP status code.

info

If not specified, status defaults to 302 Found.

Signature
func (r *Redirect) To(location string) error
Example
app.Get("/coffee", func(c fiber.Ctx) error {
  // => HTTP - GET 301 /teapot 
  return c.Redirect().Status(fiber.StatusMovedPermanently).To("/teapot")
})

app.Get("/teapot", func(c fiber.Ctx) error {
  return c.Status(fiber.StatusTeapot).Send("🍵 short and stout 🍵")
})
More examples
app.Get("/", func(c fiber.Ctx) error {
  // => HTTP - GET 302 /foo/bar 
  return c.Redirect().To("/foo/bar")
  // => HTTP - GET 302 ../login
  return c.Redirect().To("../login")
  // => HTTP - GET 302 http://example.com
  return c.Redirect().To("http://example.com")
  // => HTTP - GET 301 https://example.com
  return c.Redirect().Status(301).To("http://example.com")
})

Route​

Redirects to a specific route along with the parameters and queries.

info

If you want to send queries and params to a route, you must use the RedirectConfig struct.

Signature
func (r *Redirect) Route(name string, config ...RedirectConfig) error
Example
app.Get("/", func(c fiber.Ctx) error {
  // /user/fiber
  return c.Redirect().Route("user", fiber.RedirectConfig{
    Params: fiber.Map{
      "name": "fiber",
    },
  })
})

app.Get("/with-queries", func(c fiber.Ctx) error {
  // /user/fiber?data[0][name]=john&data[0][age]=10&test=doe
  return c.Redirect().Route("user", fiber.RedirectConfig{
    Params: fiber.Map{
      "name": "fiber",
    },
    Queries: map[string]string{
      "data[0][name]": "john",
      "data[0][age]":  "10",
      "test":          "doe",
    },
  })
})

app.Get("/user/:name", func(c fiber.Ctx) error {
  return c.SendString(c.Params("name"))
}).Name("user")

Back​

Redirects back to the referer URL. It redirects to a fallback URL if the referer header doesn't exist, with a specified status, a positive integer that corresponds to an HTTP status code.

info

If not specified, status defaults to 302 Found.

Signature
func (r *Redirect) Back(fallback string) error
Example
app.Get("/", func(c fiber.Ctx) error {
  return c.SendString("Home page")
})

app.Get("/test", func(c fiber.Ctx) error {
  c.Set("Content-Type", "text/html")
  return c.SendString(`<a href="/back">Back</a>`)
})

app.Get("/back", func(c fiber.Ctx) error {
  return c.Redirect().Back("/")
})

Controls​

info

Methods are chainable.

Status​

Sets the HTTP status code for the redirect.

info

It is used in conjunction with To, Route, and Back methods.

Signature
func (r *Redirect) Status(status int) *Redirect
Example
app.Get("/coffee", func(c fiber.Ctx) error {
  // => HTTP - GET 301 /teapot 
  return c.Redirect().Status(fiber.StatusMovedPermanently).To("/teapot")
})

RedirectConfig​

Sets the configuration for the redirect.

info

It is used in conjunction with the Route method.

Definition
// RedirectConfig is a config to use with Redirect().Route()
type RedirectConfig struct {
  Params  fiber.Map         // Route parameters
  Queries map[string]string // Query map
}

Flash Message​

Similar to Laravel, we can flash a message and retrieve it in the next request.

Messages​

Get flash messages. Check With for more information.

Signature
func (r *Redirect) Messages() map[string]string
Example
app.Get("/", func(c fiber.Ctx) error {
  messages := c.Redirect().Messages()
  return c.JSON(messages)
})

Message​

Get a flash message by key. Check With for more information.

Signature
func (r *Redirect) Message(key string) *Redirect
Example
app.Get("/", func(c fiber.Ctx) error {
  message := c.Redirect().Message("status")
  return c.SendString(message)
})

OldInputs​

Get old input data. Check WithInput for more information.

Signature
func (r *Redirect) OldInputs() map[string]string
Example
app.Get("/", func(c fiber.Ctx) error {
  oldInputs := c.Redirect().OldInputs()
  return c.JSON(oldInputs)
})

OldInput​

Get old input data by key. Check WithInput for more information.

Signature
func (r *Redirect) OldInput(key string) string
Example
app.Get("/name", func(c fiber.Ctx) error {
  oldInput := c.Redirect().OldInput("name")
  return c.SendString(oldInput)
})

With​

You can send flash messages by using With().

Signature
func (r *Redirect) With(key, value string) *Redirect
Example
app.Get("/login", func(c fiber.Ctx) error {
  return c.Redirect().With("status", "Logged in successfully").To("/")
})

app.Get("/", func(c fiber.Ctx) error {
  // => Logged in successfully
  return c.SendString(c.Redirect().Message("status"))
})

WithInput​

You can send input data by using WithInput(). They will be sent as a cookie.

This method can send form, multipart form, or query data to the redirected route depending on the request content type.

Signature
func (r *Redirect) WithInput() *Redirect
Example
// curl -X POST http://localhost:3000/login -d "name=John"
app.Post("/login", func(c fiber.Ctx) error {
  return c.Redirect().WithInput().Route("name")
})

app.Get("/name", func(c fiber.Ctx) error {
  // => John
  return c.SendString(c.Redirect().OldInput("name"))
}).Name("name")
