Package errhttp provides errors and types that make dealing with HTTP response errors easier, for the Go programming language.
Online documentation, which includes examples, can be found at: http:https://godoc.org/github.com/reiver/go-errhttp
Here is an example of wrapping an error:
import "github.com/reiver/go-errhttp"
// ...
if err := something(); nil != err {
return errhttp.BadRequestWrap(err)
}
// ...
switch err.(type) {
case errhttp.BadRequest:
//@TODO
case errhttp.NotFound:
//@TODO
case errhttp.InternalServerError:
//@TODO
case errhttp.ClientError:
//@TODO
case errhttp.ServerError:
//@TODO
default:
//@TODO
}Here is an example of using one of the package global variable errors:
import "github.com/reiver/go-errhttp"
// ...
return errhttp.ErrBadRequest
// ...
switch err.(type) {
case errhttp.BadRequest:
//@TODO
case errhttp.NotFound:
//@TODO
case errhttp.InternalServerError:
//@TODO
case errhttp.ClientError:
//@TODO
case errhttp.ServerError:
//@TODO
default:
//@TODO
}Here is another example, where it used the .ErrHTTP() method to get the HTTP response status code:
import "github.com/reiver/go-errhttp"
// ...
return errhttp.ErrBadRequest
// ...
switch casted := err.(type) {
case errhttp.ClientError:
statuscode := casted.ErrHTTP()
http.Error(responsewriter, http.StatusText(statuscode), statuscode)
return
case errhttp.ServerError:
statuscode := casted.ErrHTTP()
http.Error(responsewriter, http.StatusText(statuscode), statuscode)
return
default:
//@TODO
