fauxpas
does http errors
- HTTP error classes more in line with Ruby/Python/Etc.
- An error class for each HTTP status in case a user wants to be specific to an HTTP status code, and general purpose handlers for any error
- Work with any of the major R http clients:
crul
,curl
,httr
, (maybeRCurl
later) - Provide flexiblity for what to do on an HTTP error, including custom functions and message templates

#> Error: Request-URI Too Long (HTTP 414).
#> - The server is refusing to service the request because the Request-URI is
#> longer than the server is willing to interpret. This rare condition is only likely
#> to occur when a client has improperly converted a POST request to a GET request
#> with long query information, when the client has descended into a URI black hole
#> of redirection (e.g., a redirected URI prefix that points to a suffix of itself),
#> or when the server is under attack by a client attempting to exploit security
#> holes present in some servers using fixed-length buffers for reading or
#> manipulating the Request-URI.

#> Error: Not Found (HTTP 404).
#> - The server has not found anything matching the Request-URI. No indication is
#> given of whether the condition is temporary or permanent. The 410 (Gone) status
#> code SHOULD be used if the server knows, through some internally configurable
#> mechanism, that an old resource is permanently unavailable and has no forwarding
#> address. #> This status code is commonly used when the server does not wish to
#> reveal exactly why the request has been refused, or when no other response is
#> applicable.

http405(res)
#> Error: Method Not Allowed (HTTP 405).
x <- HTTPMethodNotAllowed$new()
x$do_verbose(res)
#> Error: Method Not Allowed (HTTP 405).
#> - The method specified in the Request-Line is not allowed for the resource
#> identified by the Request-URI. The response MUST include an Allow header
#> containing a list of valid methods for the requested resource.
