Types

type Context 

type Context struct {
	Request *http.Request
	Writer  ResponseWriter

	Params Params

	Keys map[string]interface{}

	Accepted []string

	Errors errorMsgs
	// contains filtered or unexported fields
}

func (*Context) Abort 

func (c *Context) Abort()

Abort prevents pending handlers from being called. Note that this will not stop the current handler. Let's say you have an authorization middleware that validates that the current request is authorized. If the authorization fails (ex: the password does not match), call Abort to ensure the remaining handlers for this request are not called.

func (*Context) AbortWithError 

func (c *Context) AbortWithError(code int, err error) *Error

AbortWithError calls `AbortWithStatus()` and `Error()` internally. This method stops the chain, writes the status code and pushes the specified error to `c.Errors`. See Context.Error() for more details.

func (*Context) AbortWithStatus 

func (c *Context) AbortWithStatus(code int)

AbortWithStatus calls `Abort()` and writes the headers with the specified status code. For example, a failed attempt to authenticate a request could use: context.AbortWithStatus(401).

func (c *Context) Bind(obj interface{}) error

Bind checks the Content-Type to select a binding engine automatically, Depending the "Content-Type" header different bindings are used: 

"application/json" --> JSON binding
"application/xml"  --> XML binding

otherwise --> returns an error. It parses the request's body as JSON if Content-Type == "application/json" using JSON or XML as a JSON input. It decodes the json payload into the struct specified as a pointer. It writes a 400 error and sets Content-Type header "text/plain" in the response if input is not valid.

	// client is redirected to /foo with http status code 301 for GET requests
	// and 307 for all other request methods.
	RedirectTrailingSlash bool

	// If enabled, the router tries to fix the current request path, if no
	// handle is registered for it.
	// First superfluous path elements like ../ or // are removed.
	// Afterwards the router does a case-insensitive lookup of the cleaned path.
	// If a handle can be found for this route, the router makes a redirection
	// to the corrected path with status code 301 for GET requests and 307 for
	// all other request methods.
	// For example /FOO and /..//Foo could be redirected to /foo.
	// RedirectTrailingSlash is independent of this option.
	RedirectFixedPath bool

	// If enabled, the router checks if another method is allowed for the
	// current route, if the current request can not be routed.
	// If this is the case, the request is answered with 'Method Not Allowed'
	// and HTTP status code 405.
	// If no other Method is allowed, the request is delegated to the NotFound
	// handler.
	HandleMethodNotAllowed bool
	ForwardedByClientIP    bool

	// 'X-AppEngine...' for better integration with that PaaS.
	AppEngine bool

	// If enabled, the url.RawPath will be used to find parameters.
	UseRawPath bool

	// If true, the path value will be unescaped.
	// If UseRawPath is false (by default), the UnescapePathValues effectively is true,
	// as url.Path gonna be used, which is already unescaped.
	UnescapePathValues bool

	// Value of 'maxMemory' param that is given to http.Request's ParseMultipartForm
	// method call.
	MaxMultipartMemory int64

	FuncMap template.FuncMap

type RouteInfo 

type RouteInfo struct {
	Method      string
	Path        string
	Handler     string
	HandlerFunc HandlerFunc
}

RouteInfo represents a request route's specification which contains method and path and its handler.

type RouterGroup 

type RouterGroup struct {
	Handlers HandlersChain
	// contains filtered or unexported fields
}

RouterGroup is used internally to configure router, a RouterGroup is associated with a prefix and an array of handlers (middleware).

func (*RouterGroup) Any 

func (group *RouterGroup) Any(relativePath string, handlers ...HandlerFunc) IRoutes

Any registers a route that matches all the HTTP methods. GET, POST, PUT, PATCH, HEAD, OPTIONS, DELETE, CONNECT, TRACE.

func (*RouterGroup) BasePath 

func (group *RouterGroup) BasePath() string

BasePath returns the base path of router group. For example, if v := router.Group("/rest/n/v1/api"), v.BasePath() is "/rest/n/v1/api".

func (*RouterGroup) DELETE 

func (group *RouterGroup) DELETE(relativePath string, handlers ...HandlerFunc) IRoutes

DELETE is a shortcut for router.Handle("DELETE", path, handle).

func (*RouterGroup) GET 

func (group *RouterGroup) GET(relativePath string, handlers ...HandlerFunc) IRoutes

GET is a shortcut for router.Handle("GET", path, handle).

func (*RouterGroup) Group 

func (group *RouterGroup) Group(relativePath string, handlers ...HandlerFunc) *RouterGroup

Group creates a new router group. You should add all the routes that have common middlewares or the same path prefix. For example, all the routes that use a common middleware for authorization could be grouped.

func (*RouterGroup) HEAD 

func (group *RouterGroup) HEAD(relativePath string, handlers ...HandlerFunc) IRoutes

HEAD is a shortcut for router.Handle("HEAD", path, handle).

func (*RouterGroup) Handle 

func (group *RouterGroup) Handle(httpMethod, relativePath string, handlers ...HandlerFunc) IRoutes

Handle registers a new request handle and middleware with the given path and method. The last handler should be the real handler, the other ones should be middleware that can and should be shared among different routes. See the example code in GitHub.

For GET, POST, PUT, PATCH and DELETE requests the respective shortcut functions can be used.

This function is intended for bulk loading and to allow the usage of less frequently used, non-standardized or custom methods (e.g. for internal communication with a proxy).

func (*RouterGroup) OPTIONS 

func (group *RouterGroup) OPTIONS(relativePath string, handlers ...HandlerFunc) IRoutes

OPTIONS is a shortcut for router.Handle("OPTIONS", path, handle).

func (*RouterGroup) PATCH 

func (group *RouterGroup) PATCH(relativePath string, handlers ...HandlerFunc) IRoutes

PATCH is a shortcut for router.Handle("PATCH", path, handle).

func (*RouterGroup) POST 

func (group *RouterGroup) POST(relativePath string, handlers ...HandlerFunc) IRoutes

POST is a shortcut for router.Handle("POST", path, handle).

func (*RouterGroup) PUT 

func (group *RouterGroup) PUT(relativePath string, handlers ...HandlerFunc) IRoutes

PUT is a shortcut for router.Handle("PUT", path, handle).

func (*RouterGroup) Static 

func (group *RouterGroup) Static(relativePath, root string) IRoutes

Static serves files from the given file system root. Internally a http.FileServer is used, therefore http.NotFound is used instead of the Router's NotFound handler. To use the operating system's file system implementation, use : 

router.Static("/static", "/var/www")

func (*RouterGroup) StaticFS 

func (group *RouterGroup) StaticFS(relativePath string, fs http.FileSystem) IRoutes

StaticFS works just like `Static()` but a custom `http.FileSystem` can be used instead. Gin by default user: gin.Dir()

func (*RouterGroup) StaticFile 

func (group *RouterGroup) StaticFile(relativePath, filepath string) IRoutes

StaticFile registers a single route in order to serve a single file of the local filesystem. router.StaticFile("favicon.ico", "./resources/favicon.ico")

func (*RouterGroup) Use 

func (group *RouterGroup) Use(middleware ...HandlerFunc) IRoutes

Use adds middleware to the group, see example code in GitHub.

type RoutesInfo 

type RoutesInfo []RouteInfo

RoutesInfo defines a RouteInfo array.
