🧠 Ctx

Accepts

Checks, if the specified extensions or content types are acceptable.

info

Based on the request’s Accept HTTP header.

Signature
c.Accepts(types ...string)                 string
c.AcceptsCharsets(charsets ...string)      string
c.AcceptsEncodings(encodings ...string)    string
c.AcceptsLanguages(langs ...string)        string

Example
// Accept: text/*, application/json

app.Get("/", func(c *fiber.Ctx) {
  c.Accepts("html")             // "html"
  c.Accepts("text/html")        // "text/html"
  c.Accepts("json", "text")     // "json"
  c.Accepts("application/json") // "application/json"
  c.Accepts("image/png")        // ""
  c.Accepts("png")              // ""
})

Fiber provides similar functions for the other accept headers.

// Accept-Charset: utf-8, iso-8859-1;q=0.2
// Accept-Encoding: gzip, compress;q=0.2
// Accept-Language: en;q=0.8, nl, ru

app.Get("/", func(c *fiber.Ctx) {
  c.AcceptsCharsets("utf-16", "iso-8859-1") 
  // "iso-8859-1"

  c.AcceptsEncodings("compress", "br") 
  // "compress"

  c.AcceptsLanguages("pt", "nl", "ru") 
  // "nl"
})

Append

Appends the specified value to the HTTP response header field.

caution

If the header is not already set, it creates the header with the specified value.

Signature
c.Append(field, values ...string)

Example
app.Get("/", func(c *fiber.Ctx) {
  c.Append("Link", "http://google.com", "http://localhost")
  // => Link: http://localhost, http://google.com

  c.Append("Link", "Test")
  // => Link: http://localhost, http://google.com, Test
})

Attachment

Sets the HTTP response Content-Disposition header field to attachment.

Signature
c.Attachment(file ...string)

Example
app.Get("/", func(c *fiber.Ctx) {
  c.Attachment()
  // => Content-Disposition: attachment

  c.Attachment("./upload/images/logo.png")
  // => Content-Disposition: attachment; filename="logo.png"
  // => Content-Type: image/png
})

App

Returns the *App reference so you could easily access all application settings.

Signature
c.App() *App

Example
app.Get("/bodylimit", func(c *fiber.Ctx) {
  bodylimit := c.App().Settings.BodyLimit
  c.Send(bodylimit)
})

BaseURL

Returns the base URL (protocol + host) as a string.

Signature
c.BaseURL() string

Example
// GET https://example.com/page#chapter-1

app.Get("/", func(c *fiber.Ctx) {
  c.BaseURL() // https://example.com
})

Body

Returns the request body.

Signature
c.Body() string

Example
// curl -X POST http://localhost:8080 -d user=john

app.Post("/", func(c *fiber.Ctx) {
  // Get raw body from POST request:
  c.Body() // user=john
})

Returned value is only valid within the handler. Do not store any references.
Make copies or use the Immutable setting instead. Read more...

BodyParser

Binds the request body to a struct. BodyParser supports decoding query parameters and the following content types based on the Content-Type header:

application/json
application/xml
application/x-www-form-urlencoded
multipart/form-data

Signature
c.BodyParser(out interface{}) error

Example
// Field names should start with an uppercase letter
type Person struct {
    Name string `json:"name" xml:"name" form:"name"`
    Pass string `json:"pass" xml:"pass" form:"pass"`
}

app.Post("/", func(c *fiber.Ctx) {
        p := new(Person)

        if err := c.BodyParser(p); err != nil {
            log.Fatal(err)
        }

        log.Println(p.Name) // john
        log.Println(p.Pass) // doe
})
// Run tests with the following curl commands

// curl -X POST -H "Content-Type: application/json" --data "{\"name\":\"john\",\"pass\":\"doe\"}" localhost:3000

// curl -X POST -H "Content-Type: application/xml" --data "<login><name>john</name><pass>doe</pass></login>" localhost:3000

// curl -X POST -H "Content-Type: application/x-www-form-urlencoded" --data "name=john&pass=doe" localhost:3000

// curl -X POST -F name=john -F pass=doe http://localhost:3000

// curl -X POST "http://localhost:3000/?name=john&pass=doe"

ClearCookie

Expire a client cookie (or all cookies if left empty)

Signature
c.ClearCookie(key ...string)

Example
app.Get("/", func(c *fiber.Ctx) {
  // Clears all cookies:
  c.ClearCookie()

  // Expire specific cookie by name:
  c.ClearCookie("user")

  // Expire multiple cookies by names:
  c.ClearCookie("token", "session", "track_id", "version")
})

caution

Web browsers and other compliant clients will only clear the cookie if the given options are identical to those when creating the cookie, excluding expires and maxAge. ClearCookie will not set these values for you - a technique similar to the one shown below should be used to ensure your cookie is deleted.

Example
app.Get("/set", func(c *fiber.Ctx) {
    c.Cookie(&fiber.Cookie{
        Name:     "token",
        Value:    "randomvalue",
        Expires:  time.Now().Add(24 * time.Hour),
        HTTPOnly: true,
        SameSite: "lax",
    })
})

app.Get("/delete", func(c *fiber.Ctx) {
    c.Cookie(&fiber.Cookie{
        Name:     "token",
        // Set expiry date to the past
        Expires:  time.Now().Add(-(time.Hour * 2)),
        HTTPOnly: true,
        SameSite: "lax",
    })
})

Context

Returns context.Context that carries a deadline, a cancellation signal, and other values across API boundaries.

Signature

c.Context() context.Context

Set cookie

Signature

c.Cookie(*Cookie)

type Cookie struct {
    Name     string
    Value    string
    Path     string
    Domain   string
    Expires  time.Time
    Secure   bool
    HTTPOnly bool
    SameSite string // lax, strict, none
}

Example
app.Get("/", func(c *fiber.Ctx) {
  // Create cookie
  cookie := new(fiber.Cookie)
  cookie.Name = "john"
  cookie.Value = "doe"
  cookie.Expires = time.Now().Add(24 * time.Hour)

  // Set cookie
  c.Cookie(cookie)
})

Cookies

Get cookie value by key, you could pass an optional default value that will be returned if the cookie key does not exist.

Signatures

c.Cookies(key string, defaultValue ...string) string

Example
app.Get("/", func(c *fiber.Ctx) {
  // Get cookie by key:
  c.Cookies("name")         // "john"
  c.Cookies("empty", "doe") // "doe"
})

Returned value is only valid within the handler. Do not store any references.
Make copies or use the Immutable setting instead. Read more...

Download

Transfers the file from path as an attachment.

Typically, browsers will prompt the user to download. By default, the Content-Disposition header filename= parameter is the file path (this typically appears in the browser dialog).

Override this default with the filename parameter.

Signature
c.Download(path, filename ...string) error

Example
app.Get("/", func(c *fiber.Ctx) {
  if err := c.Download("./files/report-12345.pdf"); err != nil {
    c.Next(err) // Pass err to fiber
  }
  // => Download report-12345.pdf

    c.Next(err) // Pass err to fiber
  }
  // => Download report.pdf
})

Fasthttp

You can still access and use all Fasthttp methods and properties.

Signature

info

Please read the Fasthttp Documentation for more information.

Example

app.Get("/", func(c *fiber.Ctx) {

    c.Status(500).Send(c.Error())
  })
  app.Listen(1337)
}

Format

Performs content-negotiation on the Accept HTTP header. It uses Accepts to select a proper format.

info

If the header is not specified or there is no proper format, text/plain is used.

  if err == nil {
    // Save file to root directory:
    c.SaveFile(file, fmt.Sprintf("./%s", file.Filename))
  }
})

JSON also sets the content header to application/json.

Signature
c.JSON(v interface{}) error

Example
type SomeStruct struct {
  Name string
  Age  uint8
}

app.Get("/json", func(c *fiber.Ctx) {
  // Create data struct:
  data := SomeStruct{
    Name: "Grame",
    Age:  20,
  }

  if err := c.JSON(data); err != nil {
    c.Status(500).Send(err)
    return
  }
  // => Content-Type: application/json

    return
  }
  // => Content-Type: application/json
  // => "{"name": "Grame", "age": 20}"
})

JSONP

Sends a JSON response with JSONP support. This method is identical to JSON, except that it opts-in to JSONP callback support. By default, the callback name is simply callback.

Override this by passing a named string in the method.

Signature
c.JSONP(v interface{}, callback ...string) error

Example
type SomeStruct struct {
  name string
  age  uint8
}

app.Get("/", func(c *fiber.Ctx) {
  // Create data struct:
  data := SomeStruct{
    name: "Grame",
    age:  20,
  }

  c.JSONP(data)
  // => callback({"name": "Grame", "age": 20})

  //       <http://api.example.com/users?page=5>; rel="last"
})

Locals

A method that stores variables scoped to the request and, therefore, are available only to the routes that match the request.

tip

This is useful if you want to pass some specific data to the next middleware.

Signature
c.Locals(key string, value ...interface{}) interface{}

app.Use(func(c *fiber.Ctx) {
  c.Locals("user", "admin")
  c.Next()
})

app.Get("/admin", func(c *fiber.Ctx) {
  if c.Locals("user") == "admin" {

  } else {
    c.SendStatus(403) // => 403 Forbidden
  }
})

Optionally, you could override the method by passing a string.

Signature
c.Method(override ...string) string

Example
app.Post("/", func(c *fiber.Ctx) {
  c.Method() // "POST"
})

MultipartForm

Signature
c.MultipartForm() (*multipart.Form, error)

Example
app.Post("/", func(c *fiber.Ctx) {
  // Parse the multipart form:
  if form, err := c.MultipartForm(); err == nil {
    // => *multipart.Form

    if token := form.Value["token"]; len(token) > 0 {
      // Get key value:
      fmt.Println(token[0])
    }

    // Get all files from "documents" key:
    files := form.File["documents"]
    // => []*multipart.FileHeader

    // Loop through files:
    for _, file := range files {
      fmt.Println(file.Filename, file.Size, file.Header["Content-Type"][0])
      // => "tutorial.pdf" 360641 "application/pdf"

      // Save the files to disk:
      c.SaveFile(file, fmt.Sprintf("./%s", file.Filename))
    }
  }
})

When Next is called, it executes the next method in the stack that matches the current route. You can pass an error struct within the method that will end the chaining and call the error handler.

Signature
c.Next(err ...error)

Example
app.Get("/", func(c *fiber.Ctx) {
  fmt.Println("1st route!")
  c.Next()
})

app.Get("*", func(c *fiber.Ctx) {
  fmt.Println("2nd route!")
