Functions

func Dir 

func Dir(root string, listDirectory bool) http.FileSystem

Dir returns a http.FileSystem that can be used by http.FileServer(). It is used internally in router.Static(). if listDirectory == true, then it works the same as http.Dir() otherwise it returns a filesystem that prevents http.FileServer() to list the directory files.

Types

type Accounts 

type Accounts map[string]string

Accounts defines a key/value for user/pass list of authorized logins.

type Context 

type Context struct {
	Request *http.Request
	Writer  ResponseWriter

	Params Params

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

	// Accepted defines a list of manually accepted formats for content negotiation.
	Accepted []string
	// contains filtered or unexported fields
}

Context is the most important part of gin. It allows us to pass variables between middleware, manage the flow, validate the JSON of a request and render a JSON response for example.

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(err *errx.Error)

AbortWithError calls `Abort()` and then `Error` internally. This method stops the chain, writes the status code and return a JSON body. It also sets the Content-Type as "application/json".

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) AbortWithStatusJSON 

func (c *Context) AbortWithStatusJSON(code int, jsonObj any)

AbortWithStatusJSON calls `Abort()` and then `JSON` internally. This method stops the chain, writes the status code and return a JSON body. It also sets the Content-Type as "application/json".

func (*Context) AddParam 

func (c *Context) AddParam(key, value string)

AddParam adds param to context and replaces path param key with given value for e2e testing purposes Example Route: "/user/:id" AddParam("id", 1) Result: "/user/1"

func (*Context) BindJSON added in v1.10.0 

func (c *Context) BindJSON(obj any) error

BindJSON decodes the json payload into the struct specified as a pointer. It will abort the request with HTTP 400 if any error occurs.

func (*Context) ClientIP 

func (c *Context) ClientIP() string

ClientIP implements one best effort algorithm to return the real client IP. It calls c.RemoteIP() under the hood, to check if the remote IP is a trusted proxy or not. If it is it will then try to parse the headers defined in Engine.RemoteIPHeaders (defaulting to [X-Forwarded-For, X-Real-Ip]). If the headers are not syntactically valid OR the remote IP does not correspond to a trusted proxy, the remote IP (coming from Request.RemoteAddr) is returned.

func (*Context) ContentType 

func (c *Context) ContentType() string

ContentType returns the Content-Type header of the request.

func (*Context) Cookie 

func (c *Context) Cookie(name string) (string, error)

func (*Context) Copy 

func (c *Context) Copy() *Context

Copy returns a copy of the current context that can be safely used outside the request's scope. This has to be used when the context has to be passed to a goroutine.

func (*Context) Deadline 

func (c *Context) Deadline() (deadline time.Time, ok bool)

Deadline returns that there is no deadline (ok==false) when c.Request has no Context.

func (*Context) DefaultPostForm 

func (c *Context) DefaultPostForm(key, defaultValue string) string

func (c *Context) DefaultQuery(key, defaultValue string) string

DefaultQuery returns the keyed url query value if it exists, otherwise it returns the specified defaultValue string. See: Query() and GetQuery() for further information. 

GET /?name=Manu&lastname=
c.DefaultQuery("name", "unknown") == "Manu"
c.DefaultQuery("id", "none") == "none"
c.DefaultQuery("lastname", "none") == ""

func (*Context) Done 

func (c *Context) Done() <-chan struct{}

Done returns nil (chan which will wait forever) when c.Request has no Context.

func (*Context) Err 

func (c *Context) Err() error

Err returns nil when c.Request has no Context.

func (*Context) Error 

func (c *Context) Error(err *errx.Error)

type Engine 

type Engine struct {

	// RedirectTrailingSlash enables automatic redirection if the current route can't be matched but a
	// handler for the path with (without) the trailing slash exists.
	// For example if /foo/ is requested but a route only exists for /foo, the
	// client is redirected to /foo with http status code 301 for GET requests
	// and 307 for all other request methods.
	RedirectTrailingSlash bool

	// RedirectFixedPath 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

	// HandleMethodNotAllowed if enabled, the router checks if another method is allowed for the
	// current route, if the current request can not be routed.

	UseRawPath bool

	// UnescapePathValues if true, the path value will be unescaped.

	// as url.Path gonna be used, which is already unescaped.
	UnescapePathValues bool

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

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).
