一个用Go语言编写的受Express启发的Web框架。
Fiber是一个基于Fasthttp(Go最快的HTTP引擎)构建的Go Web框架。它旨在简化零内存分配和性能的情况,以便快速开发。
package main
import (
"log"
"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"))
}
强大的路由
为您的应用程序设置路由从未如此简单!类似Express的路线定义易于理解和使用。
app.Get("/", func (c *fiber.Ctx) error {
return c.SendString("GET request")
})
app.Get("/:param", func (c *fiber.Ctx) error {
return c.SendString("param: " + c.Params("param"))
})
app.Post("/", func (c *fiber.Ctx) error {
return c.SendString("POST request")
})
服务静态文件
通过定义静态路由轻松地为您的静态HTML,CSS和JavaScript文件提供服务。您也可以在同一路径上提供多个目录的内容!
app.Static("/", "./public")
// => http://localhost:3000/hello.html
// => http://localhost:3000/js/jquery.js
// => http://localhost:3000/css/style.css
// serve from multiple directories
app.Static("/", "./files")
极限表现
由于Fiber建立在Fasthttp之上,因此您的应用程序将享受无与伦比的性能!
基准图支持API
Fiber是在Go中构建REST API的理想选择。接收和发送数据既快速又简单!
app.Get("/api/posts", func (c *fiber.Ctx) error {
posts := getPosts() // your logic
if len(posts) == 0 {
return c.Status(404).JSON(&fiber.Map{
"success": false,
"error": "There are no posts!",
})
}
return c.JSON(&fiber.Map{
"success": true,
"posts": posts,
})
})
灵活的中间件支持
从许多现有的中间件中进行选择,或者创建自己的中间件!在它们到达您的控制器之前,可以使用它们来验证和处理您应用中的某些请求。
package main
import (
"log"
"github.com/gofiber/fiber/v2"
"github.com/gofiber/fiber/v2/middleware/cors"
)
func main() {
app := fiber.New()
app.Use(cors.New())
app.Use(func (c *fiber.Ctx) error {
if c.Is("json") {
return c.Next()
}
return c.SendString("Only JSON allowed!")
})
app.Get("/", func(c *fiber.Ctx) error {
return c.JSON(fiber.Map{
"message": "Hello World",
})
})
log.Fatal(app.Listen(":3000"))
}
低内存占用
Fiber的低内存占用量使您能够实现功能,而不必担心应用程序将使用多少内存。这使您可以专注于应用程序及其业务逻辑,而不是技术细节。
模板引擎
是否要在Fiber应用程序中使用其他模板引擎?别再害怕了!由于使用了模板中间件,Fiber支持多个模板引擎,例如Handlebars和Pug 。
package main
import (
"log"
"github.com/gofiber/fiber/v2"
"github.com/gofiber/template/html"
)
func main() {
app := fiber.New(fiber.Config{
Views: html.New("./views", ".html"),
})
app.Get("/", func(c *fiber.Ctx) error {
return c.Render("index", fiber.Map{
"Title": "Hello, World!",
})
})
log.Fatal(app.Listen(":3000"))
}
WebSocket支持
在您的Fiber应用程序中使用WebSockets的强大功能!保证性能和可扩展性,以构建快速的交互式用户体验。
app.Get("/ws", websocket.New(func(c *websocket.Conn) {
// Websocket logic
for {
mtype, msg, err := c.ReadMessage()
if err != nil {
break
}
log.Printf("Read: %s", msg)
err = c.WriteMessage(mtype, msg)
if err != nil {
break
}
}
log.Println("Error:", err)
}))
速率限制器
使用Fiber,将重复请求限制为公共API和端点非常简单。
Internal Middleware
Here is a list of middleware that are included within the Fiber framework.
Middleware | Description |
---|---|
basicauth | Basic auth middleware provides an HTTP basic authentication. 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. |
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. |
timeout | Adds a max time for a request and forwards to ErrorHandler if it is exceeded. |
🧬 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! |
helmet | Helps secure your apps by setting various HTTP headers. |
jwt | JWT returns a JSON Web Token (JWT) auth middleware. |
keyauth | Key auth middleware provides a key based authentication. |
rewrite | Rewrite middleware rewrites the URL path based on provided rules. It can be helpful for backward compatibility or just creating cleaner and more descriptive links. |
session | This session middleware is build on top of fasthttp/session by @savsgio MIT. Special thanks to @thomasvvugt for helping with this middleware. |
template | This package contains 8 template engines that can be used with Fiber v1.10.x Go version 1.13 or higher is required. |
websocket | Based on Fasthttp WebSocket for Fiber with Locals support! |
