Fiber是一个受到Express启发的Web框架,建立在Go语言写的最快的FasthttpHTTP引擎的基础上。旨在简化 零内存分配和提高性能,以便快速开发。
⚡️ 快速入门
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 👋!")
})
app.Listen(":3000")
}

⚙️ 安装
Make sure you have Go installed (download). Version 1.14
or higher is required.
Initialize your project by creating a folder and then running go mod init github.com/your/repo
(learn more) inside the folder. Then install Fiber with the go get
command:
go get -u github.com/gofiber/fiber/v2
🎯 特点
💡 哲学
从Node.js切换到Go的新gopher
在开始构建Web
应用程序或微服务之前正在应对学习曲线。 Fiber
作为一个Web 框架 ,是按照极简主义的思想并遵循UNIX 方式创建的,因此新的gopher
可以在热烈和可信赖的欢迎中迅速进入Go
的世界。
Fiber
受到了互联网上最流行的Web
框架Express
的启发 。我们结合了Express
的易用性和Go
的原始性能 。如果您曾经在Node.js
上实现过Web
应用程序(使用 Express 或类似工具),那么许多方法和原理对您来说应该非常易懂。
我们关注 整个互联网 用户在issues和 Discord channel的消息,为了创建一个迅速,灵活以及友好的Go web
框架,满足任何任务,最后期限和开发者技能。就像Express
在JavaScript
世界中一样。
👀 示例
下面列出了一些常见示例。如果您想查看更多代码示例,请访问我们的Recipes代码库或API 文档 。
📖 基础路由
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) // => ✋ register
})
log.Fatal(app.Listen(":3000"))
}
📖 静态文件服务
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"))
}
📖 中间件和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"))
}

模版引擎
如果未设置模版引擎,则Fiber
默认使用html/template。
如果您要执行部分模版或使用其他引擎,例如amber,handlebars,mustache或者pug等等...
请查看我们的Template包,该包支持多个模版引擎。
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"))
}
组合路由链
📖 路由分组
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
// ...
}
日志中间件
📖 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"))
}
跨域资源共享(CORS)中间件
📖 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"))
}
通过在请求头中设置Origin
传递任何域来检查 CORS:
curl -H "Origin: http://example.com" --verbose http://localhost:3000
自定义 404 响应
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 响应
📖 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"))
}
升级到 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
}
恢复(panic)中间件
📖 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.

cache | Intercept and cache responses |
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 |
proxy | Allows you to proxy requests to a multiple servers |
requestid | Adds a requestid to every request. |
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 |
---|---|
