新增一个goods路由
controllers
// controllers/goods.go
package controllers
import (
beego "github.com/beego/beego/v2/server/web"
)
type GoodsController struct {
beego.Controller
}
func (c *GoodsController) Get() {
c.Data["Website"] = "beego.me"
c.Data["Email"] = "astaxie@gmail.com"
c.TplName = "goods.tpl"
}
router
//routers/router.go
package routers
import (
"beegodemo01/controllers"
beego "github.com/beego/beego/v2/server/web"
)
func init() {
beego.Router("/", &controllers.MainController{})
beego.Router("/goods", &controllers.GoodsController{})
}
view
//views/goods.tpl

get传参
// routers/router.go
beego.Router("/article/edit", &controllers.ArticleController{},"get:EditArticle")
// controllers/article.go
func (c *ArticleController) EditArticle() {
// 获取get传值
id := c.GetString("id")
c.Ctx.WriteString("修改新闻--"+id)
}
post 传值
router
// routers/router.go
beego.Router("/user/edit", &controllers.UserController{},"get:EditUser")
beego.Router("/user/doEdit", &controllers.UserController{},"post:DoEditUser")
controllers
//controllers/user.go
func (c *UserController) EditUser() {
c.TplName = "userEdit.html"
}
type User struct {
Username string `form:"username" json:"username"`
Password string `form:"password" json:"password"`
Hobby []string `form:"hobby" json:"h"`
}
func (c *UserController) DoEditUser() {
u := User{}
if err := c.ParseForm(&u); err != nil{
c.Ctx.WriteString("post提交失败")
return
}
fmt.Printf("%#v",u)
c.Ctx.WriteString("解析post数据成功")
}
view
// views/userEdit.html
<form action="/user/doEdit" method="post">
<div>
<span>id</span>
<input type="text" name='id'>
</div>
<div>
<span>用户名</span>
<input type="text" name='username'>
</div>
<div>
<span>密码</span>
<input type="password" name="password">
</div>
<div>
<span>爱好</span>
<input type="checkbox" value=1 id='label1' name='hobby'><label for='lable1'>吃饭</label>
<input type="checkbox" value=2 id='label2' name='hobby'><label for='lable2'>睡觉</label>
<input type="checkbox" value=3 id='label3' name='hobby'><label for='lable3'>打豆豆</label>
</div>
<input type="submit" value='提交'>
</form>
返回json数据
router
//routers/router.go
beego.Router("/user/getUser", &controllers.UserController{},"get:GetUser")
controllers
//controllers/user.go
type User struct {
Username string `form:"username" json:"username"`
Password string `form:"password" json:"password"`
Hobby []string `form:"hobby" json:"h"`
}
func (c *UserController) GetUser() {
u := User{
Username:"张三",
Password:"123456",
Hobby:[]string{"1","2"},
}
c.Data["json"] = u
c.ServeJSON()
}
map 的值实现空接口
c.Data["json"] = map[string]interface{}{"code":500,"msg":"评论出错，请重试"}
c.ServeJSON()
config配置
配置文件设置，获取
// conf/app.conf
mysqluser = "aaa"
admin ="admin","lisi"
// controllers/default.go
mysqluser,err := beego.AppConfig.String("mysqluser")
if err != nil{
return
}
fmt.Print(mysqluser)
admin,err := beego.AppConfig.Strings("admin")
if err != nil{
return
}
fmt.Printf("%v %T",admin,admin)
set get
beego.AppConfig.Set("redisuser","admin666")
redisuser,err := beego.AppConfig.String("redisuser")
if err != nil{
return
}
fmt.Print(redisuser)
cookie
// controllers/default.go
c.Ctx.SetCookie("username","aa")
// controllers/goods.go
username := c.Ctx.GetCookie("username")
c.Data["username"] = username
日志log
beego1.x有beego.ingo，2.0没有

func main() {
logs.Info("hello, world-------11")
logs.SetLogger("file",`{"filename":"logs/test.log"}`)
beego.Run()
}
日志文件
