	// Write a critical error message
	// This message should be handled differently
	// than the other ways of reporting.

	Debugf(format string, args ...any)
	// Write a test message, loglevel test
	Test(args ...any)
	Testf(format string, args ...any)
}

Default logger interface, can be used to set a logger on the request. This logger can be set in for example, the middleware, and then be used in the views by the request.

	Type string
	Text string
}

type Messages

type Messages []Message

func (*Messages) Decode

func (m *Messages) Decode(data string) error

func (Messages) Encode

func (m Messages) Encode() string

type Request

type Request struct {
	// Underlying http response writer.
	Response http.ResponseWriter

	// Underlying http request.
	Request *http.Request

	// Default data to be passed to any possible templates.
	Data *TemplateData

	// URL Parameters set inside of the router.
	URLParams URLParams

	// The request JSON object, which handles returning json responses.
	// This is mostly for semantic reasons.
	JSON *_json

	// Interfaces which can be set using the right middlewares.
	// These interfaces are not set by default, but can be set by middleware.
	User    User
	Session Session
	Logger  Logger
	URL     func(method, name string) routevars.URLFormatter
	// contains filtered or unexported fields
}

Default request to be passed around the router.

func NewRequest

func NewRequest(writer http.ResponseWriter, request *http.Request, params URLParams) *Request

Initialize a new request.

func (*Request) AddHeader

func (r *Request) AddHeader(name, value string)

Add a header.

func (*Request) DeleteCookie

func (r *Request) DeleteCookie(name string)

Delete cookies.

func (*Request) Error

func (r *Request) Error(code int, err string)

Raise an error.

func (*Request) Form

func (r *Request) Form() url.Values

Parse the form, and return the form values.

func (*Request) FormFileBuffer

func (r *Request) FormFileBuffer(name string) (*bytes.Buffer, error)

Get a form file as a buffer.

func (*Request) GetCookie

func (r *Request) GetCookie(name string) (*http.Cookie, error)

Get cookies.

func (*Request) GetData

func (r *Request) GetData(key string) interface{}

Get a data value.

func (*Request) GetHeader

func (r *Request) GetHeader(name string) string

Get a header.

func (*Request) IP

func (r *Request) IP() string

IP address of the request.

func (*Request) Method

func (r *Request) Method() string

Get the request method.

func (*Request) Next

func (r *Request) Next() string

Get the Next url. This is the url that was set in the session/cookies. This is used to redirect back to the same page.

func (*Request) ReSetNext

func (r *Request) ReSetNext()

Reset the next data.

func (*Request) Redirect

func (r *Request) Redirect(redirectURL string, statuscode int, next ...string)

Redirect to a URL. If the session is defined, the messages will be set in the session. If the `next` argument is given, it will be added to session, unless the session is not defined, the `next` parameter will be added to cookies. This means they will be carried across when rendering with request.Render(). This will be set again after the redirect, when rendering in the default Data. Optionally you could obtain this by calling request.Next().

func (*Request) Render

func (r *Request) Render(templateName string) error

Template configuration must be set before calling this function! See the templates package for more information.

func (*Request) RenderString

func (r *Request) RenderString(templateString string) error

Render a string as a template

type RequestConstraint

type RequestConstraint interface {
	*Request | *http.Request

	Get(key string) interface{}
	Exists(key string) bool
	Delete(key string)
	Destroy() error
	RenewToken() error
}

This interface will be set on the request, but is only useful if any middleware is using it. If no middleware has set it, it will remain unused.

	IsAuthenticated() bool

	// Check if the user is an administator
	IsAdmin() bool
}

Default request user interface. This interface is used to check if a user is authenticated. This interface is used by the LoginRequiredMiddleware and LogoutRequiredMiddleware. If you want to use these middlewares, you should implement this interface. And set the GetRequestUserFunc function to return a user.
