hello world
also i write an app based on beego. you can get the code from:[beepkg](https://github.com/astaxie/beepkg)
A more complete example use of beego exists here:[beepkg](https://github.com/astaxie/beepkg)
in other way i has writing a tool to quick create an app based on beego. you can get the tools from [bee](https://github.com/astaxie/bee)

## Router
============
In beego, a route is a struct paired with a URL-matching pattern. The strcut has many method with the same name of http method to server the http request. Each route is associated with a block:
In beego, a route is a struct paired with a URL-matching pattern. The struct has many method with the same name of http method to serve the http response. Each route is associated with a block.
```go
beego.RegisterController("/", &controllers.MainController{})
beego.RegisterController("/admin", &admin.UserController{})
beego.RegisterController("/admin/index", &admin.ArticleController{})
beego.RegisterController("/admin/addpkg", &admin.AddController{})
```
You can specify custom regular expressions for routes:
```go
beego.RegisterController("/admin/editpkg/:id([0-9]+)", &admin.EditController{})
beego.RegisterController("/admin/delpkg/:id([0-9]+)", &admin.DelController{})
beego.RegisterController("/:pkg(.*)", &controllers.MainController{})
```
You can also create routes for static files:
beego.BeeApp.SetStaticPath("/static","/public")
this will serve any files in /static, including files in subdirectories. For example request `/static/logo.gif` or `/static/style/main.css` will server with the file in the path `/pulic/logo.gif` or `/public/style/main.css`

## Filters / Middleware
============
You can apply filters to routes, which is useful for enforcing security, redirects, etc.
You can, for example, filter all request to enforce some type of security:
```go
var FilterUser = func(w http.ResponseWriter, r *http.Request) {
if r.URL.User == nil || r.URL.User.Username() != "admin" {
http.Error(w, "", http.StatusUnauthorized)

You can also apply filters only when certain REST URL Parameters exist:

beego.RegisterController("/:id([0-9]+)", &admin.EditController{})
beego.FilterParam("id", func(rw http.ResponseWriter, r *http.Request) {

## Controller / Struct
============
you type a ChildStruct has anonymous type `beego.Controller`
To implement a beego Controller, embed the `beego.Controller` struct:
```go
type xxxController struct {
beego.Controller
}
the `beego.Controller` is `beego.ControllerInterface` has the follow method:
```
`beego.Controller` satisfieds the `beego.ControllerInterface` interface, which defines the following methods:

In the controller you needn't to call render function. beego will auto call this function after HTTP Method Call.
You can disable automatic invokation of autorender via the AutoRender Flag:

### layout
beego also support layout. beego's layout is like this:
beego supports layouts for views. For example:
```go
this.Layout = "admin/layout.html"
this.TplNames = "admin/add.tpl"
```
in the layout.html you must define the variable like this to show sub template's content:
In layout.html you must define the variable like this to show sub template's content:
{{.LayoutContent}}
beego first Parse the file TplNames defined, then get the content from the sub template to the data["LayoutContent"], at last Parse the layout file and show it.
beego first parses the TplNames files, renders their content, and appends it to data["LayoutContent"].
### template function
beego support users to define template function like this:
```go
func hello(in string)(out string){
out = in + "world"
return
}

You can use `beego.Controller.ServeJson` or `beego.Controller.ServeXml` for serializing to Json and Xml. I found myself constantly writing code to serialize, set content type, content length, etc. Feel free to use these functions to eliminate redundant code in your app.
Helper function for serving Json, sets content type to application/json:
```go
func (this *AddController) Get() {
mystruct := { ... }
routes.ServeJson(w, &mystruct)

Helper function for serving Xml, sets content type to application/xml:
