Functions

func GetHost

func GetHost[T RequestConstraint](r T) string

Types

type CSRFToken

type CSRFToken struct {
	Token string
}

func NewCSRFToken

func NewCSRFToken(token string) *CSRFToken

func (*CSRFToken) Input

func (ct *CSRFToken) Input() template.HTML

func (*CSRFToken) String

func (ct *CSRFToken) String() string

type JSONResponse

type JSONResponse struct {
	Next   string         `json:"next,omitempty"`
	Detail string         `json:"detail,omitempty"`
	Status ResponseStatus `json:"status"`
	Data   interface{}    `json:"data"`
}

Default json response which gets returned when using (j).Encode().

type Message

type Message struct {
	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 {
	Response  http.ResponseWriter
	Request   *http.Request
	Data      *TemplateData
	Session   Session
	URLParams URLParams

	User User
	JSON *_json
	// 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) 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) GetData

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

Get a data value.

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) 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) SetData

func (r *Request) SetData(key string, value interface{})

Set a data value.

func (*Request) Write

func (r *Request) Write(b []byte) (int, error)

Write to the response.

func (*Request) WriteString

func (r *Request) WriteString(s string) (int, error)

Write a string to the response.

type RequestConstraint

type RequestConstraint interface {
	*Request | *http.Request
}

This interface is used to retrieve the request host.

type ResponseStatus

type ResponseStatus string

const (
	ResponseStatusOK       ResponseStatus = "ok"
	ResponseStatusError    ResponseStatus = "error"
	ResponseStatusRedirect ResponseStatus = "redirect"
)

type Session

type Session interface {
	Set(key string, value interface{})
	Get(key string) interface{}
	Exists(key string) bool
	Delete(key string)
	Destroy() 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.

type TemplateData

type TemplateData struct {
	Data      map[string]any
	Messages  Messages
	CSRFToken *CSRFToken
	User      interface{}
	Next      string
}

func NewTemplateData

func NewTemplateData() *TemplateData

func (*TemplateData) AddMessage

func (td *TemplateData) AddMessage(messageType, message string)

func (*TemplateData) Delete

func (td *TemplateData) Delete(key string)

func (*TemplateData) Get

func (td *TemplateData) Get(key string) interface{}

func (*TemplateData) Has

func (td *TemplateData) Has(key string) bool

func (*TemplateData) Set

func (td *TemplateData) Set(key string, value interface{})

type URLParams

type URLParams map[string]string

func (URLParams) Get

func (u URLParams) Get(key string, def ...string) string

func (URLParams) GetInt

func (u URLParams) GetInt(key string, def ...int) int

func (URLParams) Has

func (u URLParams) Has(key string) bool

type User

type User interface {
	IsAuthenticated() 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.
