MaxPostSize is the maximum number of bytes that ParseBody reads from an http.Request.Body.

Functions

func ParseBody

func ParseBody(r *http.Request, v interface{}) (int, error)

ParseBody reads a JSON-encoded body from a http.Request and unmarshals it into the provided object.

func Render

func Render(w http.ResponseWriter, httpStatus int, v interface{})

Render writes a JSON-encoded object to a http.ResponseWriter, as well as a HTTP status code.

func RenderError

func RenderError(w http.ResponseWriter, httpStatus int, err error)

RenderError writes an error, wrapped in the Message field of a JSON-encoded object to a http.ResponseWriter, as well as a HTTP status code. If the status code is 0, RenderError tries to guess the proper HTTP status code from the error type.
