一、Beego

Beego用于在Go中快速开发企业应用程序，包括RESTful API、web应用程序和后端服务。

Beego 源码地址

Beego 官方站点

Beego 官方说明

Beego的特性

  • RESTful支持
  • MVC架构
  • 模块化
  • 自动API文档
  • 注释路由
  • 命名空间
  • 开发工具集合
  • Full stack for Web & API

Beego的模块

  • orm，对象关系映射
  • session，会话
  • logs，日志
  • config，配置
  • cache，缓存

1、创建Beego项目

Go Web--Go Module

Beego 官方说明

1.1、命令行方式创建项目

Go 复制代码 
D:\GO_workspace_web>md test_beego

D:\GO_workspace_web>cd test_beego

D:\GO_workspace_web\test_beego>go mod init test_beego
go: creating new go.mod: module test_beego

D:\GO_workspace_web\test_beego>

下载并安装beego/v2

Go 复制代码 
D:\GO_workspace_web\test_beego>go get github.com/beego/beego/v2@latest

D:\GO_workspace_web\test_beego>

下面使用GoLand软件打开新建的项目

编写main.go

Go 复制代码 
package main

import "github.com/beego/beego/v2/server/web"

func main() {
	web.Run()
}

启动项目

测试：http://localhost:8080/

看到上面页面说明beego项目启动成功

1.2、使用bee工具

D:\GO_workspace_web\test_beego>

在bee命令安装:GOPATH/bin中，保证GOPATH/bin位于系统环境变量path中

bash 复制代码 
D:\GO_workspace_web\test_beego>go env GOPATH
C:\Users\Administrator\go

For Go 1.18 and newer Go versions run:

Go 复制代码 
go install github.com/beego/bee/v2@latest

And then:

Go 复制代码 
bee version

D:\GO_workspace_web\test_beego>bee version

使用bee工具创建项目

1、bee api，创建API应用

Go 复制代码 
D:\GO_workspace_web\test_beego>cd ..

D:\GO_workspace_web>bee api test_beego1
2023/08/17 00:21:38.410 [D]  init global config instance failed. If you do not use this, just ignore it.  open conf/app.conf: The system cannot find the path specified.

D:\GO_workspace_web>

与 web 相比，不需要 html、css、js这些前端资源的响应，仅仅是业务逻辑，和数据的响应。是我们需要的典型的API功能！

2、bee new 命令会自动创建beego 的go mod项目。

同时会初始化基础的目录结构！

Go 复制代码

D:\GO_workspace_web>

web项目，比 api项目增加 views（html模板）和static（css，image，js）静态资源相关给目录。

运行应用前，保证全部的包被安装：

bee run 命令会利用 fsnotify 监控文件系统，若文件改动时，可以实时重新编译运行。

2、Admin管理后台

Beego 内置了管理后台，用于监视和统计应用信息，默认关闭。通过配置控制：

修改main.go文件

Go 复制代码 
package main

import (
	beego "github.com/beego/beego/v2/server/web"
	_ "test_beego2/routers"
)

func main() {
	// 是否开启Admin
	beego.BConfig.Listen.EnableAdmin = true
	// Admin监听的地址和端口
	beego.BConfig.Listen.AdminAddr = "localhost"
	beego.BConfig.Listen.AdminPort = 8088
	beego.Run()
}

访问：http://localhost:8088/

支持：

Requests statistics， 请求统计信息
性能分析

  • lookup goroutine，goroutine 信息
  • lookup heap，堆栈信息
  • lookup threadcreate，线程创建信息
  • lookup block，阻塞信息
  • get cpuprof，CPU的pprof
  • get memprof，Memory的pprof
  • gc summary，GC 概要

健康检查
任务
配置状态

  • configs, 配置
  • routers, 路由
  • filters, 过滤器

Web framework-Gin

人必须要成长！

如今一道为尊，万道相和，几乎很难破。最可怕的是苍穹！
