beego实现用户未登录跳转到登录页面

主要涉及内容：

1. 自动路由
2. 过滤器
3. session控制
4. 表单请求数据处理

main.go

//这里应该加载 "github.com/astaxie/beego/context" 否则会加载src/context
//过滤器
var FilterUser = func(ctx *context.Context){
	_, ok := ctx.Input.Session("uid").(string)
	ok2 := strings.Contains(ctx.Request.RequestURI, "/login")
	if !ok && !ok2{
		ctx.Redirect(302, "/login/index")
	}
}

func main() {
	//注册过滤器
	beego.InsertFilter("/*", beego.BeforeRouter, FilterUser)
	//打开session
	beego.BConfig.WebConfig.Session.SessionOn = true
	setWebAutoRouter()
	beego.Run()
}

//注册自动路由
func setWebAutoRouter(){
	beego.AutoRouter(&controllers.TestController{})
	beego.AutoRouter(&controllers.LoginController{})
}

loginController.go

type LoginController struct{
	beego.Controller
}

type user struct {
	Id int `form:"-"`
	Name string `form:"username"`
	Age int `form:"age"`
	Email string
}

func (this *LoginController) Index(){
	//获取session值
	this.Data["uid"] = this.GetSession("uid")
	this.TplName = "login.html"
}

func (this *LoginController) Register(){
	u := user{}
	//处理表单提交的数据
	if err := this.ParseForm(&u); err != nil{
		fmt.Println(err)
	} else {
		//注册session值
		this.SetSession("uid", u.Name)
	}
	this.Data["uid"] = this.GetSession("uid")
	this.TplName = "login.html"
}

testController.go

type TestController struct{
	beego.Controller
}

func (this *TestController) Index(){
	paramMap := this.Ctx.Input.Params()
	//获取RESTFUL风格的参数
	//此时的URL为 localhost:8080/test/index/aaa/bbb
	this.Data["Website"] = paramMap["0"]		//aaa
	this.Data["Email"] = paramMap["1"]		//bbb

	v := this.GetSession("uid")
	this.Data["uid"] = v.(string)

	this.TplName = "test.html"
}
