Hi,
when using curl's URL functions, is it possible to validate the URL?
In the documentation of curl_url_set() it says:
"CURLUPART_URL
... The string must point to a correctly formatted "RFC 3986+" URL or be
a NULL pointer."
What exactly does "RFC 3986+" mean? And what happens if the URL string
is not a correct "RFC 3986+" URL?
Consider the following test program:
--------------------------------------------------
#include <stdio.h>
#include <curl/curl.h>
static
void
validate_url(CURLU *url_handle, const char *url)
{
int rc = curl_url_set(url_handle, CURLUPART_URL, url, 0);
printf("URL '%s': rc %d\n", url, rc);
}
int
main(void)
{
CURLU *url_handle = curl_url();
/* Valid URL: */
validate_url(url_handle,
"https://curl.haxx.se/libcurl/c/curl_url_set.html";);
/* Invalid because of '<' and '>': */
validate_url(url_handle, "https://curl.haxx.se/<invalid>");
/* Invalid percent-escaped sequence: */
validate_url(url_handle, "https://curl.haxx.se/%XY";);
curl_url_cleanup(url_handle);
return 0;
}
-----------------------------------------------------
While the first URL is valid, I consider the second and third one
invalid. But curl_url_set() returns CURLUE_OK for them. Is this expected?
