bee工具的使用及创建第一个项目

前提文章：beego的安装及配置参数说明-CSDN博客

提示：beego框架下项目需要再GOPATH/src下进行开发，我的GOPATH是C:\Users\leell\go

一、web项目创建

通过 bee new 创建web项目

C:\Users\leell\go\src>bee new beego-web
2024/01/15 21:40:04.553 [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.
2024/01/15 21:40:04 INFO     ▶ 0001 Generate new project support go modules.

2024/01/15 21:40:04 SUCCESS  ▶ 0003 New application successfully created!

beego-web 文件结构：

beego-web
├── conf
│   └── app.conf
├── controllers
│   └── default.go
├── main.go
├── models
├── routers
│   └── router.go

访问localhost:8080

二、api项目创建

通过 bee api 创建api项目

C:\Users\leell\go\src>bee api beego-api
2024/01/15 21:54:15.539 [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.

2024/01/15 21:54:15 SUCCESS  ▶ 0003 New API successfully created!

启动beego-web web服务

C:\Users\leell\go\src\beego-api>go mod tidy
go: finding module for package github.com/kr/text
go: found github.com/kr/text in github.com/kr/text v0.2.0C:\Users\leell\go\src\beego-api>bee run

生成的routers.go文件，更多路由设置参考文章：beego 路由设置 - 汇思班

func init() {ns := beego.NewNamespace("/v1",beego.NSNamespace("/object",beego.NSInclude(&controllers.ObjectController{},),),beego.NSNamespace("/user",beego.NSInclude(&controllers.UserController{},),),)beego.AddNamespace(ns)
}

当访问接口:

[root@k8s-master01 fastcms]# curl -X 'GET'  'http://192.168.10.101:8080/v1/user'   -H 'accept: application/json'
{"user_11111": {"Id": "user_11111","Username": "astaxie","Password": "11111","Profile": {"Gender": "male","Age": 20,"Address": "Singapore","Email": "astaxie@gmail.com"}}
}

三、bee项目打包

pack 目录用来发布应用的时候打包，会把项目打包成 zip 包，这样我们部署的时候直接把打包之后的项目上传，解压就可以部署了

C:\Users\leell\go\src\beego-web>bee pack
______
| ___ \
| |_/ /  ___   ___
| ___ \ / _ \ / _ \
| |_/ /|  __/|  __/
\____/  \___| \___| v2.1.0
2024/01/16 00:14:00 INFO     ▶ 0001 Packaging application on 'C:\Users\leell\go\src\beego-web'...
2024/01/16 00:14:00 INFO     ▶ 0002 Building application (beego-web)...
2024/01/16 00:14:00 INFO     ▶ 0003 Using: GOOS=windows GOARCH=amd64
2024/01/16 00:14:05 SUCCESS  ▶ 0004 Build Successful!
2024/01/16 00:14:05 INFO     ▶ 0005 Writing to output: C:\Users\leell\go\src\beego-web\beego-web.tar.gz
2024/01/16 00:14:05 INFO     ▶ 0006 Excluding relpath prefix: .
2024/01/16 00:14:05 INFO     ▶ 0007 Excluding relpath suffix: .go:.DS_Store:.tmp:go.mod:go.sum
2024/01/16 00:14:06 SUCCESS  ▶ 0008 Application packed!

会在beego-web目录下生成一个beego-web.tar.gz文件，文件列表：

views
static
conf
beego-web.exe

四、异常问题

刚开始访问http://192.168.10.101:8080/v1/user 出现下面的问题，排查了好久，都开始怀疑beego是否是个稳定的框架了。

结果发现可能是beego是v1版本，升级了v2就正常了

PS C:\Users\leell\go\src\beego-api> go get github.com/astaxie/beego/v2
go: module github.com/astaxie/beego@upgrade found (v1.12.3), but does not contain package github.com/astaxie/beego/v2

这样设计合理多了，里面的接口地址通过接口注解就能访问了，做过Java来写go没有注解确实还是希望有这种便捷的方式开发，看看下面接口注解方式是不是很nice了，完全很轻松实现restful api的请求方式。通过bee api生成的项目还有put、post、delete的请求方式，自行观看。

// @Title GetAll
// @Description get all Users
// @Success 200 {object} models.User
// @router / [get]
func (u *UserController) GetAll() {users := models.GetAllUsers()u.Data["json"] = usersu.ServeJSON()
}// @Title Get
// @Description get user by uid
// @Param	uid		path 	string	true		"The key for staticblock"
// @Success 200 {object} models.User
// @Failure 403 :uid is empty
// @router /:uid [get]
func (u *UserController) Get() {uid := u.GetString(":uid")if uid != "" {user, err := models.GetUser(uid)if err != nil {u.Data["json"] = err.Error()} else {u.Data["json"] = user}}u.ServeJSON()
}
