beego 简介

beego 是一个快速开发 Go 应用的 HTTP 框架，他可以用来快速开发 API、Web 及后端服务等各种应用，是一个 RESTful 的框架，主要设计灵感来源于 tornado、sinatra 和 flask 这三个框架，但是结合了 Go 本身的一些特性（interface、struct 嵌入等）而设计的一个框架。

beego 安装

go get github.com/astaxie/beego

bee工具

go get github.com/beego/bee

1.new 命令（PC）

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

2.api 命令（App）

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

3.run 命令

我们在开发 Go 项目的时候最大的问题是经常需要自己手动去编译再运行，bee run 命令是监控 beego 的项目，通过 fsnotify监控文件系统。但是注意该命令必须在$GOPATH/src/appname下执行。
