![]() ![]() The R bindings will automatically do some type checking and coercion Option names are notĭocumentation to set options of the correct type. 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. Option to TRUE in the handle of the request. If you do want the curl_fetch_* functions toĪutomatically raise an error, you should set the FAILONERROR "The requested URL /CRAN_mirrorZ.csv was not found on this server." unlink('mirrors.csv') Need to implement such application logic yourself and check if the Using curl_fetch_memory or curl_fetch_disk you If the request was completed but returned a non-200 status code. Important to realize that these do not raise an error ![]() When using any of the curl_fetch_* functions it is However it is quite complex and requires careful specification of The system allows for running many concurrent non-blocking requests. Out <- multi_run(pool = pool) done: : HTTP: 200 The callback functions get triggered when each ![]() When we call multi_run(), all scheduled requests are "report-to: Ĭurl_fetch_multi('', done = cb, pool = pool) attr(*, "names")= chr "redirect" "namelookup" "connect" "pretransfer". Which waits for the request to complete and returns a list with allĬontent (data, headers, status, timings) of the server response. The curl_fetch_memory function is a blocking interface ![]()
