Types

type Context

type Context interface {
	context.Context

	Request() *http.Request
	ResponseWriter() http.ResponseWriter
	RequestId() string

	Next()
	Abort() // 终止。如果授权失败（例如：密码不匹配），请调用Abort以确保不调用此请求的其余处理程序
	AbortWithStatus(code int)
	AbortWithStatusJSON(code int, jsonObj interface{})
	IsAborted() bool // 判断当前context是否已终止

	Param(key string) string
	Query(key string) string
	PostForm(key string) string
	FormFile(name string) (*multipart.FileHeader, error)
	MultipartForm() (*multipart.Form, error)
	SaveUploadedFile(file *multipart.FileHeader, dst string) error
	Bind(obj interface{}, bindType ...string) error
	ContentType() string

	Set(key string, value interface{})
	Get(key string) (value interface{}, exists bool)
	GetString(key string) (s string)
	GetBool(key string) (b bool)
	GetInt64(key string) (i64 int64)

	Status(code int)
	GetStatus() int
	Header(key, value string)
	GetHeader(key string) string
	SetCookie(cookie *http.Cookie)
	GetCookie(name string) (string, error)
	Redirect(code int, location string)
}

type Handler

type Handler func(Context)

type Reader

type Reader struct {
	ContentType   string
	ContentLength int64
	Reader        io.Reader
	Headers       map[string]string
}

Reader contains the IO reader and its length, and custom ContentType and other headers.

func (Reader) Render

func (r Reader) Render(w http.ResponseWriter) (err error)

Render (Reader) writes data with custom ContentType and headers.

func (Reader) WriteContentType

func (r Reader) WriteContentType(w http.ResponseWriter)

WriteContentType (Reader) writes custom ContentType.

type Render

type Render interface {
	// Render writes data with custom ContentType.
	Render(http.ResponseWriter) error
	// WriteContentType writes custom ContentType.
	WriteContentType(w http.ResponseWriter)
}

Render interface is to be implemented by JSON, XML, HTML, YAML and so on.
