体验下 Go 语言的魅力（初试）

上述为Donng所陈述（可以跳转到那里查看）

我就简单说一下怎末让他简单跑起来

首先就是你要有一个 go 的环境啦！

https://golang.google.cn/dl/   
// 去这个地方下载安装 go的环境
// windows： 后缀 msi
// linux： gz
// mac： pkg
//FreeBSD： gz
复制代码

ps：我是直接使用的 beego框架

go get github.com/astaxie/beego  // beego 框架
go get github.com/beego/bee  // bee 工具
复制代码

测试是否安装成功

控制台 cmd/powershell/vscode   输入  bee
// 下面是bee的功能
Bee is a Fast and Flexible tool for managing your Beego Web Application.

Usage:

    bee command [arguments]

The commands are:

    version     show the bee & beego version
    migrate     run database migrations
    api         create an api application base on beego framework
    bale        packs non-Go files to Go source files    
    new         create an application base on beego framework
    run         run the app which can hot compile
    pack        compress an beego project
    fix         Fixes your application by making it compatible with newer versions of Beego
    dlv         Start a debugging session using Delve
    dockerize   Generates a Dockerfile for your Beego application
    generate    Source code generator
    hprose      Creates an RPC application based on Hprose and Beego frameworks
    new         Creates a Beego application
    pack        Compresses a Beego application into a single file
    rs          Run customized scripts
    run         Run the application by starting a local development server
    server      serving static content over HTTP on port
    
Use bee help [command] for more information about a command.
复制代码

安装完之后 beego 提供了几种快速搭建方法如下

new命令：bee new myproject(name)

new 命令是新建一个 Web 项目，我们在命令行下执行  bee new <项目名> 就可以创建一个新的项目。但是注意该命令必须在  $GOPATH/src 下执行。最后会在  $GOPATH/src 相应目录下生成如下目录结构的项目：

bee new myproject
[INFO] Creating application...
/gopath/src/myproject/
/gopath/src/myproject/conf/
/gopath/src/myproject/controllers/
/gopath/src/myproject/models/
/gopath/src/myproject/static/
/gopath/src/myproject/static/js/
/gopath/src/myproject/static/css/
/gopath/src/myproject/static/img/
/gopath/src/myproject/views/
/gopath/src/myproject/conf/app.conf
/gopath/src/myproject/controllers/default.go
/gopath/src/myproject/views/index.tpl
/gopath/src/myproject/main.go

api命令：bee api apiproject(name)

上面的 new 命令是用来新建 Web 项目，不过很多用户使用 beego 来开发 API 应用。所以这个  api 命令就是用来创建 API 应用的，执行命令之后如下所示：

bee api apiproject
create app folder: /gopath/src/apiproject
create conf: /gopath/src/apiproject/conf
create controllers: /gopath/src/apiproject/controllers
create models: /gopath/src/apiproject/models
create tests: /gopath/src/apiproject/tests
create conf app.conf: /gopath/src/apiproject/conf/app.conf
create controllers default.go: /gopath/src/apiproject/controllers/default.go
create tests default.go: /gopath/src/apiproject/tests/default_test.go
create models object.go: /gopath/src/apiproject/models/object.go
create main.go: /gopath/src/apiproject/main.go
复制代码

apiproject
├── conf
│   └── app.conf
├── controllers
│   └── object.go
│   └── user.go
├── docs
│   └── doc.go
├── main.go
├── models
│   └── object.go
│   └── user.go
├── routers
│   └── router.go
└── tests
    └── default_test.go
复制代码

从上面的目录我们可以看到和 Web 项目相比，少了 static 和 views 目录，多了一个 test 模块，用来做单元测试的。

同时，该命令还支持一些自定义参数自动连接数据库创建相关 model 和 controller: bee api [appname] [-tables=""] [-driver=mysql] [-conn="root:<password>@tcp(127.0.0.1:3306)/test"] 如果 conn 参数为空则创建一个示例项目，否则将基于链接信息链接数据库创建项目。

启动命令：bee run

bee run

我们打开浏览器就可以看到效果 http://localhost:8080/ :
