Types

type Context 

type Context struct {
	context.Context

	Request *http.Request
	Writer  ResponseWriter

	Params Params

	// Keys is a key/value pair exclusively for the context of each request.
	Keys map[string]interface{}

	Error error
	// 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) 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 (*Context) Bind 

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

func (*Context) ClientIP 

func (c *Context) ClientIP() string

ClientIP implements a best effort algorithm to return the real client IP, it parses X-Real-IP and X-Forwarded-For in order to work properly with reverse-proxies such us: nginx or haproxy. Use X-Forwarded-For before X-Real-Ip as nginx uses X-Real-Ip with the proxy's IP.

	// 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.

	// 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

	// #726 #755 If enabled, it will thrust some headers starting with
	// 'X-AppEngine...' for better integration with that PaaS.

	// 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

	// RemoveExtraSlash a parameter can be parsed from the URL even with extra slashes.
	// See the PR #1817 and issue #1644
	RemoveExtraSlash bool
	// contains filtered or unexported fields
