Fiber是移植NodeJS的Express框架改以Go語言編寫。本套件基於Fasthttp，Fasthttp有不分配記憶體空間和Request Pool的特性，在網路效能方面有著顯著的效能。

⚡️ 快速入門

package main

import "github.com/gofiber/fiber/v2"

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

	app.Get("/", func(c *fiber.Ctx) error {
		return c.SendString("Hello, World 👋!")
	})

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

💡 理念

不少Node.js的工程師跳到Go必須學習一些知識，因此做了一個跟Express一樣的Fiber省這些麻煩。設計還是照原本的極簡主義還有遵循UNIX慣例，因此新手們可以無痛迅速進入Go的世界。

Fiber 受到 網路上最流行的Web框架ExpressJS啟發，結合Express的易用性和Go的高效能。若你之前用過Node.js寫Web應用(使用ExpressJS/Koa或類似工具)，那你已經上手了。

有什麼問題請發issues或加入Discord channel討論，我們想要創造快速、彈性、友善的社群給任何人使用！就像Express那樣。

👀 範例

以下是一些常見範例。

更多程式碼在範例專案中或直接看API文件。

📖 Basic Routing

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

	// GET /john
	app.Get("/:name", func(c *fiber.Ctx) error {
		msg := fmt.Sprintf("Hello, %s 👋!", c.Params("name"))
		return c.SendString(msg) // => Hello john 👋!
	})

	// GET /john/75
	app.Get("/:name/:age/:gender?", func(c *fiber.Ctx) error {
		msg := fmt.Sprintf("👴 %s is %s years old", c.Params("name"), c.Params("age"))
		return c.SendString(msg) // => 👴 john is 75 years old
	})

	// GET /dictionary.txt
	app.Get("/:file.:ext", func(c *fiber.Ctx) error {
		msg := fmt.Sprintf("📃 %s.%s", c.Params("file"), c.Params("ext"))
		return c.SendString(msg) // => 📃 dictionary.txt
	})

	// GET /flights/LAX-SFO
	app.Get("/flights/:from-:to", func(c *fiber.Ctx) error {
		msg := fmt.Sprintf("💸 From: %s, To: %s", c.Params("from"), c.Params("to"))
		return c.SendString(msg) // => 💸 From: LAX, To: SFO
	})

	// GET /api/register
	app.Get("/api/*", func(c *fiber.Ctx) error {
		msg := fmt.Sprintf("✋ %s", c.Params("*"))
		return c.SendString(msg) // => ✋ /api/register
	})

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

📖 Serving Static Files

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

	app.Static("/", "./public")
	// => http://localhost:3000/js/script.js
	// => http://localhost:3000/css/style.css

	app.Static("/prefix", "./public")
	// => http://localhost:3000/prefix/js/script.js
	// => http://localhost:3000/prefix/css/style.css

	app.Static("*", "./public/index.html")
	// => http://localhost:3000/any/path/shows/index/html

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

📖 Middleware & Next

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

	// Match any route
	app.Use(func(c *fiber.Ctx) error {
		fmt.Println("🥇 First handler")
		return c.Next()
	})

	// Match all routes starting with /api
	app.Use("/api", func(c *fiber.Ctx) error {
		fmt.Println("🥈 Second handler")
		return c.Next()
	})

	// GET /api/register
	app.Get("/api/list", func(c *fiber.Ctx) error {
		fmt.Println("🥉 Last handler")
		return c.SendString("Hello, World 👋!")
	})

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

界面引擎

📖 設定 📖 引擎 📖 渲染

當不指定樣板引擎時Fiber預設用html/template。

如果你想要執行部份或用別的樣板引擎amber、handlebars、mustache、pug之類…請參考符合多樣板引擎的樣板套件。

package main

import (
	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/template/pug"
)

func main() {
	// You can setup Views engine before initiation app:
	app := fiber.New(fiber.Config{
		Views: pug.New("./views", ".pug"),
	})

	// And now, you can call template `./views/home.pug` like this:
	app.Get("/", func(c *fiber.Ctx) error {
		return c.Render("home", fiber.Map{
			"title": "Homepage",
			"year":  1999,
		})
	})

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

Grouping routes into chains

📖 Group

func middleware(c *fiber.Ctx) error {
	fmt.Println("Don't mind me!")
	return c.Next()
}

func handler(c *fiber.Ctx) error {
	return c.SendString(c.Path())
}

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

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

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

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

	// ...
}

中介器logger

📖 Logger

package main

import (
	"log"

	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/fiber/v2/middleware/logger"
)

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

	app.Use(logger.New())

	// ...

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

跨網域資源共享 (CORS)

📖 CORS

import (
	"log"

	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/fiber/v2/middleware/cors"
)

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

	app.Use(cors.New())

	// ...

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

在Origin header中放網域來檢查CORS:

curl -H "Origin: http://example.com" --verbose http://localhost:3000

客制404回應

📖 HTTP Methods

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

	app.Static("/", "./public")

	app.Get("/demo", func(c *fiber.Ctx) error {
		return c.SendString("This is a demo!")
	})

	app.Post("/register", func(c *fiber.Ctx) error {
		return c.SendString("Welcome!")
	})

	// Last middleware to match anything
	app.Use(func(c *fiber.Ctx) error {
		return c.SendStatus(404)
		// => 404 "Not Found"
	})

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

JSON 回應

📖 JSON

type User struct {
	Name string `json:"name"`
	Age  int    `json:"age"`
}

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

	app.Get("/user", func(c *fiber.Ctx) error {
		return c.JSON(&User{"John", 20})
		// => {"name":"John", "age":20}
	})

	app.Get("/json", func(c *fiber.Ctx) error {
		return c.JSON(fiber.Map{
			"success": true,
			"message": "Hi John!",
		})
		// => {"success":true, "message":"Hi John!"}
	})

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

WebSocket 升級

📖 Websocket

import (
    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/websocket"
)

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

  app.Get("/ws", websocket.New(func(c *websocket.Conn) {
    for {
      mt, msg, err := c.ReadMessage()
      if err != nil {
        log.Println("read:", err)
        break
      }
      log.Printf("recv: %s", msg)
      err = c.WriteMessage(mt, msg)
      if err != nil {
        log.Println("write:", err)
        break
      }
    }
  }))

  log.Fatal(app.Listen(":3000"))
  // ws://localhost:3000/ws
}

Recover 中介器

📖 Recover

import (
	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/fiber/recover"
)

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

	app.Use(recover.New())

	app.Get("/", func(c *fiber.Ctx) error {
		panic("normally this would crash your app")
	})

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

🧬 Internal Middleware

Here is a list of middleware that are included within the Fiber framework.

It calls the next handler for valid credentials and 401 Unauthorized for missing or invalid credentials. | | compress | Compression middleware for Fiber, it supports deflate, gzip and brotli by default. | | cors | Enable cross-origin resource sharing CORS with various options. | | csrf | Protect from CSRF exploits. | | filesystem | FileSystem middleware for Fiber, special thanks and credits to Alireza Salary | | favicon | Ignore favicon from logs or serve from memory if a file path is provided. | | limiter | Rate-limiting middleware for Fiber. Use to limit repeated requests to public APIs and/or endpoints such as password reset. | | logger | HTTP request/response logger. | | pprof | Special thanks to Matthew Lee @mthli | | recover | Recover middleware recovers from panics anywhere in the stack chain and handles the control to the centralized ErrorHandler. |

🧬 External Middleware

List of externally hosted middleware modules and maintained by the Fiber team.

Middleware	Description
adaptor	Converter for net/http handlers to/from Fiber request handlers, special thanks to @arsmn!
