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
```go
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")
}
```
## 🤖 性能
这些测试由[TechEmpower](https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=plaintext)和[Go Web](https://github.com/smallnest/go-web-framework-benchmark) 执行。如果要查看所有结果，请访问我们的[Wiki](https://docs.gofiber.io/benchmarks) 。
## ⚙️ 安装
首先， [下载](https://golang.org/dl/)并安装Go。 需要`1.14`或更高版本。
使用[`go get`](https://golang.org/cmd/go/#hdr-Add_dependencies_to_current_module_and_install_them)命令完成安装：
```bash
export GO111MODULE=on
export GOPROXY=https://goproxy.cn
go get github.com/gofiber/fiber/v2

## 💡 哲学
从[Node.js](https://nodejs.org/en/about/)切换到[Go](https://golang.org/doc/)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](https://github.com/gofiber/fiber/issues)和Discord [channel](https://gofiber.io/discord)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。

#### 📖 [**基础路由**](https://docs.gofiber.io/#basic-routing)
```go
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 👋!

### 模版引擎
📖 [配置](https://docs.gofiber.io/fiber#config)
📖 [模版引擎](https://github.com/gofiber/template)
📖 [渲染](https://docs.gofiber.io/context#render)
如果未设置模版引擎，则`Fiber`默认使用[html/template](https://golang.org/pkg/html/template/)。
如果您要执行部分模版或使用其他引擎，例如[amber](https://github.com/eknkc/amber)，[handlebars](https://github.com/aymerick/raymond)，[mustache](https://github.com/cbroglie/mustache)或者[pug](https://github.com/Joker/jade)等等...
请查看我们的[Template](https://github.com/gofiber/template)包，该包支持多个模版引擎。
```go
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](https://docs.gofiber.io/application#group)
```go
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](https://docs.gofiber.io/middleware/logger)
```go
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](https://docs.gofiber.io/middleware/cors)
```go
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：
```bash
curl -H "Origin: http://example.com" --verbose http://localhost:3000
```
### 自定义404响应
📖 [HTTP Methods](https://docs.gofiber.io/application#http-methods)
```go
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](https://docs.gofiber.io/ctx#json)
```go
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
📖 [Websocket](https://github.com/gofiber/websocket)
```go
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](https://docs.gofiber.io/middleware/recover)
```go
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"))
}
```
