Functions ¶
func ErrorAndLog ¶ added in v0.107.53
func ErrorAndLog( ctx context.Context, l *slog.Logger, r *http.Request, w http.ResponseWriter, code int, format string, args ...any, )
ErrorAndLog writes a formatted HTTP error response and logs it at slog.LevelError level. l, r, and w must not be nil.
func UserAgent ¶ added in v0.107.14
func UserAgent() (ua string)
UserAgent returns the ID of the service as a User-Agent string. It can also be used as the value of the Server HTTP header.
func WriteJSONResponse ¶ added in v0.107.14
func WriteJSONResponse( ctx context.Context, l *slog.Logger, w http.ResponseWriter, r *http.Request, code int, resp any, )
WriteJSONResponse writes headers with the code, encodes resp into w, and logs any errors it encounters. r is used to get additional information from the request. l, w, and r must not be nil.
func WriteJSONResponseError ¶ added in v0.107.37
func WriteJSONResponseError( ctx context.Context, l *slog.Logger, w http.ResponseWriter, r *http.Request, err error, )
WriteJSONResponseError encodes err as a JSON error into w, and logs any errors it encounters. r is used to get additional information from the request. l, w, and r must not be nil.
func WriteJSONResponseOK ¶ added in v0.107.37
func WriteJSONResponseOK( ctx context.Context, l *slog.Logger, w http.ResponseWriter, r *http.Request, v any, )
WriteJSONResponseOK writes headers with the code 200 OK, encodes v into w, and logs any errors it encounters. r is used to get additional information from the request. l, w, and r must not be nil.
func WriteTextPlainDeprecated ¶ added in v0.107.14
func WriteTextPlainDeprecated( ctx context.Context, l *slog.Logger, w http.ResponseWriter, r *http.Request, ) (isPlainText bool)
WriteTextPlainDeprecated responds to the request with a message about deprecation and removal of a plain-text API if the request is made with the "text/plain" Content-Type. All arguments must not be nil.
Types ¶
type DefaultRegistrar ¶ added in v0.107.69
type DefaultRegistrar struct {
// contains filtered or unexported fields
}
DefaultRegistrar is an implementation of Registrar that registers handlers after applying a user-provided wrapper function.
func NewDefaultRegistrar ¶ added in v0.107.69
func NewDefaultRegistrar(mux *http.ServeMux, wrap WrapFunc) (r *DefaultRegistrar)
NewDefaultRegistrar returns a new properly initialized *DefaultRegistrar. mux and wrap must not be nil.
func (*DefaultRegistrar) Register ¶ added in v0.107.69
func (r *DefaultRegistrar) Register(method, path string, h http.HandlerFunc)
Register implements the Registrar interface.
type EmptyRegistrar ¶ added in v0.107.69
type EmptyRegistrar struct{}
EmptyRegistrar is an implementation of Registrar that does nothing.
func (EmptyRegistrar) Register ¶ added in v0.107.69
func (EmptyRegistrar) Register(_, _ string, _ http.HandlerFunc)
Register implements the Registrar interface.
type ErrorCode ¶ added in v0.107.37
type ErrorCode string
ErrorCode is the error code as used by the HTTP API. See the ErrorCode definition in the OpenAPI specification.
type HTTPAPIErrorResp ¶ added in v0.107.37
HTTPAPIErrorResp is the error response as used by the HTTP API. See the BadRequestResp, InternalServerErrorResp, and similar objects in the OpenAPI specification.
type JSONDuration ¶ added in v0.107.37
JSONDuration is a time.Duration that can be decoded from JSON and encoded into JSON according to our API conventions.
func (JSONDuration) MarshalJSON ¶ added in v0.107.37
func (d JSONDuration) MarshalJSON() (b []byte, err error)
MarshalJSON implements the json.Marshaler interface for JSONDuration. err is always nil.
func (*JSONDuration) UnmarshalJSON ¶ added in v0.107.37
func (d *JSONDuration) UnmarshalJSON(b []byte) (err error)
UnmarshalJSON implements the json.Marshaler interface for *JSONDuration.
type JSONTime ¶ added in v0.107.37
JSONTime is a time.Time that can be decoded from JSON and encoded into JSON according to our API conventions.
func (JSONTime) MarshalJSON ¶ added in v0.107.37
MarshalJSON implements the json.Marshaler interface for JSONTime. err is always nil.
func (*JSONTime) UnmarshalJSON ¶ added in v0.107.37
UnmarshalJSON implements the json.Marshaler interface for *JSONTime.
type RegisterFunc ¶ added in v0.107.10
type RegisterFunc func(method, url string, handler http.HandlerFunc)
RegisterFunc is the function that sets the handler to handle the URL for the method.
TODO(e.burkov, a.garipov): Get rid of it.
type Registrar ¶ added in v0.107.69
type Registrar interface {
Register(method, path string, h http.HandlerFunc)
}
Registrar registers an HTTP handler for a method and path.
TODO(s.chzhen): Implement [httputil.Router].
