x$do_verbose(res)
#> 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)

x <- HTTPNotFound$new()
x$do_verbose(resp)
#> 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.

library("httr")
res <- GET("https://httpbin.org/status/405")
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.
