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

"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.

type Engine

type Engine struct {
	RouterGroup

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

	// 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

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