The libcurlĭocumentation explains what each option does. Options supported by your version of libcurl. Use the curl_options() function to get a list of the Handle_setopt(h, copypostfields = "moo=moomooo") AfterĬreating a handle object, we can set the libcurl options and http h <- new_handle(failonerror = TRUE)Ĭurl_fetch_memory('', handle = h) Error in curl_fetch_memory("", : The requested URL returned error: 404Ĭreating a new handle is done using new_handle.
