Go语言之高级篇beego框架安装与使用

一、beego框架

1、beego框架简介

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。

参考官网：https://beego.me/docs/intro/

2、beego 的执行逻辑

beego 是一个典型的 MVC 架构，它的执行逻辑如下图所示：

3、beego 项目结构
一般的 beego 项目的目录如下所示：

├── conf
│ └── app.conf
├── controllers
│ ├── admin
│ └── default.go
├── main.go
├── models
│ └── models.go
├── static
│ ├── css
│ ├── ico
│ ├── img
│ └── js
└── views
├── admin
└── index.tpl

从上面的目录结构我们可以看出来 M（models 目录）、V（views 目录）和 C（controllers 目录）的结构， main.go 是入口文件。

4、beego框架安装

go get github.com/astaxie/beego

参考：https://github.com/astaxie/beego

设置GoPATH路径：

5、bee工具

go get github.com/beego/bee

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。但是注意该命令必段在$GOPATH/src 下执行。

api 命令是用来创建API应用的。

安装步骤：

#绝对路径，运行：bee

#安装bee
C:Users560140>go get github.com/beego/bee

#绝对路径，运行：bee
C:Users560140>%GOPATH%/bin/bee
