Revel controller profile

Custom Controller is a directly or indirectly *revel.Controller struct.

Typical usage:

type AppController struct {
  *revel.Controller
}

*revel.Controller must be the first embedded type in your custom struct

revel.Controller is used in the context of the request, which contains request and response data, please go to the godoc for the full content, here is a definition (and the definition of the secondary type):

type Controller struct {
    Name          string          // 控制器名称, 比如： "Application"
    Type          *ControllerType // 控制器类型描述
    MethodType    *MethodType     // 控制器方法描述
    AppController interface{}     // 控制器实例

    Request  *Request
    Response *Response
    Result   Result

    Flash      Flash                  // 用户 cookie, 在请求之后清空
    Session    Session                // Session, 保存在cookie中，签名。
    Params     *Params                // URL和表单中的参数(包扩 multipart).
    Args       map[string]interface{} // 每个请求的暂存空间
    RenderArgs map[string]interface{} // 传递给模板的参数
    Validation *Validation            // 数据验证帮助器
}

// 统一的请求参数包装
// 包括:
// - URL 查询字符串
// - Form 表单字段
// - File 文件上传
type Params struct {
    url.Values
    Files map[string][]*multipart.FileHeader
}

type Request struct {
    *http.Request
    ContentType string
}

type Response struct {
    Status      int
    ContentType string
    Headers     http.Header
    Cookies     []*http.Cookie

    Out http.ResponseWriter
}

As part of HTTP request processing, Revel instantiates a controller and sets up revel.Controller embeds properties, so Revel does not share instances between requests, and the controller is independent for the processing of each request.
