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, (maybe RCurl later)
  • Provide flexiblity for what to do on an HTTP error, including custom functions and message templates

CRAN version


Dev version


use with crul

cli <- HttpClient$new("https://httpbin.org/status/414")
res <- cli$get()
#> Error: Request-URI Too Long (HTTP 414).
#> Error: Request-URI Too Long (HTTP 414).
x <- HTTPRequestURITooLong$new()
#> 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.

use with curl

h <- curl::new_handle()
resp <- curl::curl_fetch_memory("https://httpbin.org/status/404", h)
#> Error: Not Found (HTTP 404).
#> Error: Not Found (HTTP 404).
x <- HTTPNotFound$new()
#> 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.

use with httr

res <- GET("https://httpbin.org/status/405")
#> Error: Method Not Allowed (HTTP 405).
x <- HTTPMethodNotAllowed$new()
#> 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.
