Fiber Go 🐮 Request Methods

These are how you access client request data.

🚀General Request Info

• ctx.Method() []byte → HTTP method (GET, POST, etc.)
• ctx.Path() []byte → Request path (e.g. /users/123)
• ctx.RequestURI() []byte → Full request URI
• ctx.Host() []byte → Host header
• ctx.RemoteAddr() net.Addr → Client IP + port
• ctx.RemoteIP() net.IP → Just the client IP

⭐Query & Params

• ctx.QueryArgs() *fasthttp.Args → All query string args (?foo=bar)
• ctx.QueryArgs().Peek("foo") → []byte value for foo
• ctx.UserValue("param") → Path parameter (if you use a router like fasthttprouter)

⭐Headers

• ctx.Request.Header (struct with methods):
• .Peek("Header-Name") []byte
• .ContentType() []byte
• .UserAgent() []byte
• .Referer() []byte
• .Cookie("name") []byte

⭐Body

• ctx.PostBody() []byte → Raw body
• ctx.FormValue("key") []byte → Form field (works with application/x-www-form-urlencoded)
• ctx.MultipartForm() (*multipart.Form, error) → File uploads / multipart form
• ctx.IsBodyStream() → Whether body is a streaming input

Response — w methods

These control what gets sent back.

😁Headers & Status

• ctx.SetStatusCode(code int) → Set status (200, 404, etc.)
• ctx.Response.Header.Set("Header", "value")
• ctx.Response.Header.SetContentType("application/json")
• ctx.Response.Header.SetCanonical([]byte("X-Header"), []byte("val"))
• ctx.Response.Header.SetCookie(cookie *fasthttp.Cookie)

🐼 Body Writing

• ctx.SetBody([]byte)
• ctx.SetBodyString(string)
• ctx.SetBodyStream(r io.Reader, size int)
• ctx.Write([]byte) → Writes to response (append-style)
• ctx.WriteString(string)
• ctx.SendFile("path/to/file") → Serve static files

👉 Redirects

• ctx.Redirect(uri string, statusCode int)
• ctx.RedirectBytes(uri []byte, statusCode int)

⚙️ Utility & Middleware Helpers

• ctx.Next() → (if using middleware chains, e.g. in fasthttprouter)
• ctx.Done() → Context cancellation
• ctx.Time() → Request start timestamp
• ctx.Response.Reset() → Clear response
• ctx.Request.Reset() → Clear request

✅ Quick Example

Simple API using Go with Fiber

func main() {
  app := fiber.New()

  api := app.Group("/api", middleware) // /api

  v1 := api.Group("/v1", middleware)   // /api/v1
  v1.Get("/list", handler)             // /api/v1/list
  v1.Get("/user", handler)             // /api/v1/user

  v2 := api.Group("/v2", middleware)   // /api/v2
  v2.Get("/list", handler)             // /api/v2/list
  v2.Get("/user", handler)             // /api/v2/user

  log.Fatal(app.Listen(":3000"))
}
