Fiber是一个基于Express的 Web框架,建立在Go语言写的 最快的FasthttpHTTP引擎的基础上。皆在简化 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"
func main() {
app := fiber.New()
app.Get("/", func(c *fiber.Ctx) {
c.Send("Hello, World!")
})
app.Listen(3000)
}
⚙️ 安装
首先, 下载并安装Go。 1.11
或更高。
使用go get
命令完成安装:
export GO111MODULE=on
export GOPROXY=https://goproxy.cn
go get -u github.com/gofiber/fiber

🎯 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过程。 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可以以热烈和可信赖的欢迎方式迅速进入Go的世界。
Fiber 受 Internet上最流行的Web框架Expressjs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.js或类似工具),那么许多方法和原理对您来说似乎非常易懂。
👀 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存储库或访问我们的API文档 。
Routing
func main() {
app := fiber.New()
// GET /john
app.Get("/:name", func(c *fiber.Ctx) {
fmt.Printf("Hello %s!", c.Params("name"))
// => Hello john!
})
// GET /john
app.Get("/:name/:age?", func(c *fiber.Ctx) {
fmt.Printf("Name: %s, Age: %s", c.Params("name"), c.Params("age"))
// => Name: john, Age:
})
// GET /api/register
app.Get("/api*", func(c *fiber.Ctx) {
fmt.Printf("/api%s", c.Params("*"))
// => /api/register
})
app.Listen(3000)
}
Serve static files
https://fiber.wiki/application#static
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
app.Listen(3000)
}
Middleware & Next
https://fiber.wiki/routing#middleware https://fiber.wiki/context#next
func main() {
app := fiber.New()
// Match any route
app.Use(func(c *fiber.Ctx) {
fmt.Println("First middleware")
c.Next()
})
// Match all routes starting with /api
app.Use("/api", func(c *fiber.Ctx) {
fmt.Println("Second middleware")
c.Next()
})
// POST /api/register
app.Post("/api/register", func(c *fiber.Ctx) {
fmt.Println("Last middleware")
c.Send("Hello, World!")
})
app.Listen(3000)
}

Template engines
https://fiber.wiki/application#settings https://fiber.wiki/context#render
Supported engines:
func main() {
// You can setup template engine before initiation app:
app := fiber.New(&fiber.Settings{
TemplateEngine: "mustache",
TemplateFolder: "./views",
TemplateExtension: ".tmpl",
})
// OR after initiation app at any convenient location:
app.Settings.TemplateEngine = "mustache"
app.Settings.TemplateFolder = "./views"
app.Settings.TemplateExtension = ".tmpl"
// And now, you can call template `./views/home.tmpl` like this:
app.Get("/", func(c *fiber.Ctx) {
c.Render("home", fiber.Map{
"title": "Homepage",
"year": 1999,
})
})
// ...
}
Grouping routes into chains
https://fiber.wiki/application#group
func main() {
app := fiber.New()
// Root API route
api := app.Group("/api", cors()) // /api
// API v1 routes
v1 := api.Group("/v1", mysql()) // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
// API v2 routes
v2 := api.Group("/v2", mongodb()) // /api/v2
v2.Get("/list", handler) // /api/v2/list
v2.Get("/user", handler) // /api/v2/user
// ...
}
Middleware logger
https://fiber.wiki/middleware#logger
import (
"github.com/gofiber/fiber"
"github.com/gofiber/fiber/middleware"
)
func main() {
app := fiber.New()
// If you want to change default Logger config
loggerConfig := middleware.LoggerConfig{
Format: "${time} - ${method} ${path}\n",
TimeFormat: "Mon, 2 Jan 2006 15:04:05 MST",
}
// Middleware for Logger with config
app.Use(middleware.Logger(loggerConfig))
// ...
}
Cross-Origin Resource Sharing (CORS)
https://fiber.wiki/middleware#cors
CORS is a mechanism that uses additional HTTP headers to tell browsers to give a web application running at one origin, access to selected resources from a different origin. A web application executes a cross-origin HTTP request when it requests a resource that has a different origin (domain, protocol, or port) from its own.
import (
"github.com/gofiber/fiber"
"github.com/gofiber/fiber/middleware"
)
func main() {
app := fiber.New()
// Connect CORS for each route as middleware
app.Use(middleware.CORS())
app.Get("/", func(c *fiber.Ctx) {
c.Send("CORS is enabled!")
})
app.Listen(3000)
}
Check CORS by passing any domain in Origin
header:
curl -H "Origin: http://example.com" --verbose http://localhost:3000
Custom 404 response
func main() {
app := fiber.New()
app.Static("/public")
app.Get("/demo", func(c *fiber.Ctx) {
c.Send("This is a demo!")
})
app.Post("/register", func(c *fiber.Ctx) {
c.Send("Welcome!")
})
// Last middleware to match anything
app.Use(func(c *fiber.Ctx) {
c.SendStatus(404) // => 404 "Not Found"
})
app.Listen(3000)
}
JSON Response
https://fiber.wiki/context#json
type User struct {
Name string `json:"name"`
Age int `json:"age"`
}
func main() {
app := fiber.New()
app.Get("/user", func(c *fiber.Ctx) {
c.JSON(&User{"John", 20})
// {"name":"John", "age":20}
})
app.Get("/json", func(c *fiber.Ctx) {
c.JSON(&fiber.Map{
"success": true,
"message": "Hi John!",
})
// {"success":true, "message":"Hi John!"}
})
app.Listen(3000)
}
WebSocket support
https://fiber.wiki/application#websocket
func main() {
app := fiber.New()
app.WebSocket("/ws", func(c *fiber.Conn) {
for {
mt, msg, err := c.ReadMessage()
if err != nil {
log.Println("read:", err)
break
}
log.Printf("recovery: %s", msg)
err = c.WriteMessage(mt, msg)
if err != nil {
log.Println("write:", err)
break
}
}
})
// Listen on ws://localhost:3000/ws
app.Listen(3000)
}
Recover middleware
https://fiber.wiki/middleware#recover
package main
import (
"github.com/gofiber/fiber"
"github.com/gofiber/fiber/middleware"
)
func main() {
app := fiber.New()
app.Use(middleware.Recover(func(c *fiber.Ctx, err error) {
log.Println(err) // "Something went wrong!"
c.SendStatus(500) // Internal Server Error
})))
app.Get("/", func(c *fiber.Ctx) {
panic("Something went wrong!")
})
app.Listen(3000)
}
