Go語言之高級篇beego框架安裝與使用

 

一、beego框架

1、beego框架簡介

beego 是一個快速開發 Go 應用的 HTTP 框架，他可以用來快速開發 API、Web 及后端服務等各種應用，是一個 RESTful 的框架，主要設計靈感來源於 tornado、sinatra 和 flask 這三個框架，但是結合了 Go 本身的一些特性（interface、struct 嵌入等）而設計的一個框架。

參考官網：https://beego.me/docs/intro/

 

2、beego 的執行邏輯

beego 是一個典型的 MVC 架構，它的執行邏輯如下圖所示：

3、beego 項目結構
一般的 beego 項目的目錄如下所示：

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

從上面的目錄結構我們可以看出來 M（models 目錄）、V（views 目錄）和 C（controllers 目錄）的結構， main.go 是入口文件。

 

4、beego框架安裝

go get github.com/astaxie/beego

參考：https://github.com/astaxie/beego

設置GoPATH路徑：

 

 

 5、bee工具

go get github.com/beego/bee

new命令是新建一個Web項目，我們在命令行下執行bee new<項目名>就可以創建一個新的項目。但是注意該命令必段在$GOPATH/src 下執行。

api 命令 是用來創建API應用的。

 

 安裝步驟：

#絕對路徑，運行：bee

#安裝bee
C:\Users\560140>go get github.com/beego/bee

#絕對路徑，運行：bee
C:\Users\560140>%GOPATH%/bin/bee

 6、beego創建項目

創建web項目： bee new WEB 

C:\Users\560140>bee new WEB
