Revel框架安装

官网：http://revel.github.io/tutorial/index.html
中文社区：http://www.gorevel.cn/

一、安装Revel框架
   下载Revel框架源码，将其源码放入%GOPATH%src/github.com/revel/revel目录下，然后在%GOPATH%src目录下进行编译操作：
   编译：go build github.com/revel/revel
   结果报错，如下：
   src\github.com\revel\revel\revel.go:17:2: cannot find package "github.com/ag
   torre/gocolorize" in any of:
   D:\Go\src\github.com\agtorre\gocolorize (from $GOROOT)
   D:\GO_WorkSpace\src\github.com\agtorre\gocolorize (from $GOPATH)
   src\github.com\revel\revel\compress.go:13:2: cannot find package "github.com
   /klauspost/compress/gzip" in any of:
   D:\Go\src\github.com\klauspost\compress\gzip (from $GOROOT)
   D:\GO_WorkSpace\src\github.com\klauspost\compress\gzip (from $GOPATH
   )
   src\github.com\revel\revel\compress.go:14:2: cannot find package "github.com
   /klauspost/compress/zlib" in any of:
   D:\Go\src\github.com\klauspost\compress\zlib (from $GOROOT)
    D:\GO_WorkSpace\src\github.com\klauspost\compress\zlib (from $GOPATH
   )
   src\github.com\revel\revel\i18n.go:15:2: cannot find package "github.com/rev
   el/config" in any of:
    D:\Go\src\github.com\revel\config (from $GOROOT)
    D:\GO_WorkSpace\src\github.com\revel\config (from $GOPATH)
   src\github.com\revel\revel\router.go:18:2: cannot find package "github.com/r
   evel/pathtree" in any of:
   D:\Go\src\github.com\revel\pathtree (from $GOROOT)
   D:\GO_WorkSpace\src\github.com\revel\pathtree (from $GOPATH)
   import cycle not allowed
   package github.com/revel/revel
   imports golang.org/x/net/websocket
   imports golang.org/x/net/websocket
   src\golang.org\x\net\websocket\watcher.go:13:2: cannot find package "gopkg.i
   n/fsnotify.v1" in any of:
   D:\Go\src\gopkg.in\fsnotify.v1 (from $GOROOT)
    D:\GO_WorkSpace\src\gopkg.in\fsnotify.v1 (from $GOPATH)

   根据错误信息，分别下载以下包：
   github.com/agtorre/gocolorize
   github.com/klauspost/compress
   github.com/revel/config
   github.com/revel/pathtree
   golang.org/x/net
   gopkg.in/fsnotify.v1

   将各个包的源码放在相应的路径下。然后再次执行：
       go build github.com/revel/revel
   编译成功

二、安装Revel命令行工具
   下载Revel命令行工具源码，将其源码放入%GOPATH%src/github.com/revel/cmd目录下，然后在%GOPATH%src目录下进行编译操作：
   编译： go build github.com/revel/cmd/revel
   结果报错，如下：
   D:\GO_WorkSpace\src\github.com\revel\cmd\revel\test.go:19:2: cannot find package        "github.com/revel/modules/testrunner/app/controllers" in any of:
    D:\Go\src\github.com\revel\modules\testrunner\app\controllers (from $GOROOT)

D:\GO_WorkSpace\src\github.com\revel\modules\testrunner\app\controllers (from $GOPATH)

   根据错误信息，下载以下包：
   github.com/revel/modules
   将其源码放在相应的路径下。然后再次执行：
       go build github.com/revel/cmd/revel
   编译成功

三、创建 Revel 应用
   重启命令行工具，然后在%GOPATH%src目录下创建 Revel 应用。
   命令：
       revel new MyRevelApp
       revel run MyRevelApp

四、打开浏览器访问 http://localhost:9000
   默认监听9000端口。

五、Revel指令
   1、revel
   在命令行输入`revel`，得到所有revel指令的说明：
       usage: revel command [arguments]

The commands are:

            new create a skeleton Revel application
            run run a Revel application
            build build a Revel application (e.g. for deployment)
           package package a Revel application (e.g. for deployment)
           clean clean a Revel application's temp files
           test run all tests from the command-line
           version displays the Revel Framework and Go version

       Use "revel help [command]" for more information.

   2、revel help [command]
   revel help [command]用于获取相关指令的帮助说明。例：

   在命令行输入`revel help new`，得到所有关于new指令的说明：
       usage: revel new [path] [skeleton]

New creates a few files to get a new Revel application running quickly.

It puts all of the files in the given import path, taking the final element in
the path to be the app name.

Skeleton is an optional argument, provided as an import path

For example:

revel new import/path/helloworld

           revel new import/path/helloworld import/path/skeleton

六、Revel框架的MVC模式概念
   MVC（模型-视图-控制器）：
       模型：描述基本的数据对象，特定的查询和更新逻辑。
       视图：一些模板，用于将数据呈现给用户。
       控制器：执行用户的请求，准备用户所需的数据，并指定模板进行渲染。

七、Revel路由配置
   在Conf目录下的routes文件进行配置
