Functions

func Recovery

func Recovery(log LogFunc) routing.Handler

Recovery returns a handler that handles panics and errors occurred while servicing an HTTP request.

The handler will recover from panics and render the recovered error or the error returned by a handler. If the error is not a routing.HTTPError, it will respond with http.StatusInternalServerError. Otherwise, it will use the status code of the HTTPError.

A log function can be provided to log a message whenever an error is handled. If nil, no message will be logged.

r.Use(fault.Recovery(log.Printf))

Types
