beego实现用户未登录跳转到登录页面[go语言]

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"
}
