Types

type App

type App struct {
	Requests    []Path
	Handlers    HandlerMap
	Middlewares Handlers
	Prefix      string

	Routers RouterMap
	// contains filtered or unexported fields
}

App is the key struct of the package. App as a member of plugin entity contains the request and the corresponding handler. Prefix is the url prefix and MiddlewareList is for control flow.

func (*App) AppendReqAndResp

func (app *App) AppendReqAndResp(url, method string, handler []Handler)

AppendReqAndResp stores the request info and handle into app. support the route parameter. The route parameter will be recognized as wildcard store into the RegUrl of Path struct. For example:

/user/:id      => /user/(.*)
/user/:id/info => /user/(.*?)/info

The RegUrl will be used to recognize the incoming path and find the handler.

func (app *App) Group(prefix string, middleware ...Handler) *RouterGroup

Group add middlewares and prefix for App.

func (*App) HEAD

func (app *App) HEAD(url string, handler ...Handler) *App

HEAD is a shortcut for app.AppendReqAndResp(url, "head", handler).

func (*App) Name

func (app *App) Name(name string)

	UserValue map[string]interface{}
	// contains filtered or unexported fields
}

Context is the simplify version of web framework context. But it is important which will be used in plugins to custom the request and response. And adapter will help to transform the Context to the web framework`s context. It has three attributes. Request and response are belongs to net/http package. UserValue is the custom key-value store of context.

func NewContext
