Beego框架学习（二）

摘要：本节主要是关于post请求获取数据以及起来格式数据渲染方式（json、xml等）

2、Post请求

//获取请求消息

//router.go
beego.Router("/add_user",&controllers.UserController)


//user.html
<form action="add_user" method="post">
     用户名：<input type="text" name="user_name">
     密码：<input type="password" name="password">
     <input type="sumbit" value="提交">
</form>


//user.go
func (u *UserController) Post(){
    user := u.GetString("user_name")
    passwd := u.GetString("password")
    fmt.Println(user)
    fmt.Println(passwd)
    u.Ctx.WriteString("提交成功")
}

----------------------------------------------------------------------------

//form表单解析到结构体

//router.go
beego.Router("/add_user",&controllers.UserController)


//user.html
<form action="add_user" method="post">
     用户名：<input type="text" name="user_name">
     密码：<input type="password" name="password">
     <input type="sumbit" value="提交">
</form>


//user.go
type student struct{
    Id int
    Name string `form:"user_name"`
    Password string `form:"password"`
}

func (u *UserController) Post(){
    student := Student{}
    u.ParseForm(&student)
    
    fmt.Println(student.Name)
    fmt.Println(student.Password)
    u.Ctx.WriteString("提交成功")
}

----------------------------------------------------------------------------

//获取ajax数据
//router.go
beego.Router("/add_user_ajax",&controllers.UserController)


//user.html
<form id="add_user">
     用户名：<input type="text" id="user_name">
     密码：<input type="password" id="password">
     <input type="button" value="提交">
</form>


//user.go
type student struct{
    Id int
    Name string `form:"user_name"`
    Password string `form:"password"`
}

func (u *UserController) Post(){
    student := Student{}
    u.ParseForm(&student)
    
    fmt.Println(student.Name)
    fmt.Println(student.Password)
    u.Ctx.WriteString("提交成功")
}

二、其他格式数据渲染方法

1、json格式：会设置 content-type 为 application/json

type TestController struct {
    beego.Controller

}

type Person struct {
    Id int
    Name string
    Gender string
}

func (g *TestController)Get()  {
    test_data := Person{Id:123,Name:"zhiliao",Gender:"男"}
    g.Data["json"] = &test_data 
    fmt.Println(test_data)
    g.ServeJSON()
    //g.TplName = "test.html"
}

2、xml格式：会设置 content-type 为 application/xml

test_data := Person{Id:123,Name:"zhiliao",Gender:"男"}
g.Data["xml"] = &test_data                        
g.ServeXML()

3、jsonp格式：会设置 content-type 为 application/javascript

test_data := Person{Id:123,Name:"zhiliao",Gender:"男"}
g.Data["jsonp"] = &test_data                  
g.ServeJSONP()

4、yaml格式：会以文件传输的方式，yaml就是键值对

test_data := Person{Id:123,Name:"zhiliao",Gender:"男"}
g.Data["yaml"] = &test_data
g.ServeYAML()
