先创建一个beego项目  
项目结构  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JqMjAxNzIxMTgxMQ_size_16_color_FFFFFF_t_70]  
1.conf  
这个目录做一些配置，项目名称、不同运行环境端口、数据库用户名、密码、端口，开启调试等

appname = myapp1
    runmode = dev
    [dev]
    httpport=8080
    [prod]
    httpport=8081
    [test]
    httpport = 8082
    mysqladdr="127.0.0.1
    mysqlport=9090
    mysqluser=root
    mysqlpassword=123456
    copyrequestbody=true

2.路由配置  
controller的名称、方式为get还是post  
router.go

package routers
    
    import (
    	"github.com/astaxie/beego"
    	"myapp1/controllers"
    )
    
    
    func init() {
    
        beego.Router("/index", &controllers.MainController{},"post:Post")
        beego.Router("/",&controllers.MainController{},"get:Get;post:Post")
    	beego.Router("/index1",&controllers.MainController{},"get:Get")
    	beego.Router("/index2",&controllers.MainController{},"*:Get")
        beego.Router("/test",&controllers.TestControler{},"get:Get;post:Post")
        beego.Router("/test_input",&controllers.Test_InputController{},"get:Get;post:Post")
        beego.Router("/test_login",&controllers.Test_loginController{},"get:Login;post:Post")
        beego.Router("/testModel",&controllers.Test_ModelController{},"get:Get;post:Post")
    	beego.Router("/testModel2",&controllers.TestModel2Controller{},"get:Get;post:Post")
        beego.Router("/login",&controllers.LoginController{},"get:Get;post:Post")
    }

3.models层：数据处理  
最常用的是操作数据库  
user.go

package models
    
    import (
    	"fmt"
    	"github.com/astaxie/beego/orm"
    	_ "github.com/go-sql-driver/mysql"
    )
    
    type Users struct{
    	Id int
    	Username string
    	Password string
    }
    var db orm.Ormer
    func init(){
    	//开启调试模式
    	orm.Debug=true
    	//获取数据库
    	orm.RegisterDataBase("default","mysql","root:123456@tcp(127.0.0.1:3306)/testgo?charset=utf8",30)
    	orm.RegisterModel(new(Users))
    	db=orm.NewOrm()
    	fmt.Println("init success")
    }
    func AddUsers(users *Users) (int64,error){
    
    	fmt.Println(users.Username,users.Password)
    
    
    	//id,err:=db.InsertOrUpdate(users)
    	id,err:=db.Insert(users)
    	fmt.Println(id,err)
    	if err!=nil{
    		db.Rollback()
    	}
    	return id,err
    }
    func ReadAllUser() []Users{
    	var users []Users
    	qb,_:=orm.NewQueryBuilder("mysql")
    	qb.Select("*").From("users")
    	sql:=qb.String()
    	db.Raw(sql).QueryRows(&users)
    	return users
    }

4.controller层  
这里调用models层方法返回数据，在通过数据方式传递给view层，并指明tpl模板，是view层和models层的桥梁  
login.tpl

package controllers
    
    import (
    	"github.com/astaxie/beego"
    	"myapp1/models"
    )
    
    type LoginController struct {
    	beego.Controller
    }
    func (c *LoginController) Get(){
    	c.Data["website"]="https://www.baidu.com"
    	c.Data["isDisplay"]=false
    	c.Data["content1"]="content1"
    	c.Data["content2"]="content2"
    	users:=models.ReadAllUser()
    
    	c.Data["users"]=users
    	c.Data["len"]= len(users)
    	c.TplName="login.tpl"
    }

5.view层，接受controller传递的数据，显示到网页  
login.tpl

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
        <style>
    
            body{
                //background-color: #00FFFF;
            }
    
        </style>
    </head>
    <body>
        <form action="" method="post">
            用户名:<input type="text" name="username"/><br>
            密码:<input type="password"  name="password"/><br>
            <input type="submit" value="登录">
    
    
        </form><br>
        <div>
    
    
            <a href="{
       {.website}}">{
       {.website}}}</a>
        </div>
        <div>
            {
       {if .isDisplay}}
                <em>{
       {.content1}}</em>
            {
       {else}}
                <em>{
       {.content2}}</em>
            {
       {end}}
            <h2>Users表</h2>
            <table border="1">
    
            <tr><th>Id</th><th>username</th><th>Password</th></tr>
    
    
    
            {
       {range .users}}
                <tr> <td>{
       {.Id}}</td><td>{
       {.Username}}</td><td>{
       {.Password}}</td></tr>
    
            {
       {end}}
            </table>
    
    
    
    
        </div>
    </body>
    </html>

运行结果如下
