Go web开发框架 Baa
**
Baa
** 一个简单高效的Go web开发框架。主要有路由、中间件，依赖注入和HTTP上下文构成。
Baa 不使用 ``反射``和``正则``，没有魔法的实现。
**快速上手**
**安装：**
<pre class="brush:cpp; toolbar: true; auto-links: false;">go get -u gopkg.in/baa.v1</pre>
**示例：**
<pre class="brush:cpp; toolbar: true; auto-links: false;">package main
import (
"gopkg.in/baa.v1"
)
func main() {
app := baa.New()
app.Get("/", func(c *baa.Context) {
c.String(200, "Hello World!")
})
app.Run(":1323")
}</pre>
**
特性
**
*
支持静态路由、参数路由、组路由（前缀路由/命名空间）和路由命名
*
路由支持链式操作
*
路由支持文件/目录服务
*
支持中间件和链式操作
*
支持依赖注入*
*
支持JSON/JSONP/XML/HTML格式输出
*
统一的HTTP错误处理
*
统一的日志处理
*
支持任意更换模板引擎（实现baa.Renderer接口即可）
**

**性能测试**
和快速的Echo框架对比 [Echo](https://github.com/labstack/echo)
**> 注意：**
[Echo](https://github.com/labstack/echo) 在V2版本中使用了fasthttp，我们这里使用 [Echo V1](https://github.com/labstack/echo/releases/tag/v1.4) 测试。
**
路由测试
**
使用 [go-http-routing-benchmark] (https://github.com/safeie/go-http-routing-benchmark) 测试, 2016-02-27 更新.

HTTP测试
**
Baa:
<pre class="brush:cpp; toolbar: true; auto-links: false;">package main
import (
"github.com/baa-middleware/logger"
"github.com/baa-middleware/recovery"
"gopkg.in/baa.v1"
)
func hello(c *baa.Context) {
c.String(200, "Hello, World!\n")
}
func main() {
b := baa.New()
b.Use(logger.Logger())
b.Use(recovery.Recovery())
b.Get("/", hello)
b.Run(":8001")
}</pre>
Echo:
<pre class="brush:cpp; toolbar: true; auto-links: false;">package main
import (
"github.com/labstack/echo"
mw "github.com/labstack/echo/middleware"
)
// Handler
func hello(c *echo.Context) error {
return c.String(200, "Hello, World!\n")
}
func main() {
// Echo instance
e := echo.New()
// Middleware
e.Use(mw.Logger())
// Routes
e.Get("/", hello)
// Start server
e.Run(":8001")
}</pre>
**
测试结果:

> Baa 在http中的表现还稍稍比 Echo 好一些。
