Syntax issue in curl for getting a file from http site
Hi All
I am using curl in my client environment. We need to pull a file from the libraries site. All the files are having perticular URL which can be used to get the files. Only issue is, when we fire that command , it will take to authentication page 1st. once authentication is succed, it will redirected back to that file location.
when i fire this command
** apended "a" before http to avoid making that a URL in this blog
its showing
location is the authentication site and finally comming out as
Connection #0 to host XXXXXXXXX left intact
Can you please let me know what alternative i can try to acomplish this?
--Thanks in advance

curlopt_followlocation
CURLOPT_FOLLOWLOCATION(3) curl_easy_setopt options CURLOPT_FOLLOWLOCATION(3)NAME
CURLOPT_FOLLOWLOCATION - follow HTTP 3xx redirects
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FOLLOWLOCATION, long enable);
DESCRIPTION
A long parameter set to 1 tells the library to follow any Location: header that the server sends as part of a HTTP header in a 3xx
response. The Location: header can specify a relative or an absolute URL to follow.
libcurl will issue another request for the new URL and follow new Location: headers all the way until no more such headers are returned.
CURLOPT_MAXREDIRS(3) can be used to limit the number of redirects libcurl will follow.
libcurl limits what protocols it automatically follows to. The accepted protocols are set with CURLOPT_REDIR_PROTOCOLS(3). By default
libcurl will allow all protocols on redirect except those disabled for security reasons: Since 7.19.4 FILE and SCP are disabled, and since
7.40.0 SMB and SMBS are also disabled.
When following a Location:, the 3xx response code that redirected it also dictates which request method it will use in the subsequent
request: For 301, 302 and 303 responses libcurl will switch method to GET unless CURLOPT_POSTREDIR(3) instructs libcurl otherwise. All
other 3xx codes will make libcurl send the same method again.
For users who think the existing location following is too naive, too simple or just lacks features, it is very easy to instead implement
your own redirect follow logic with the use of curl_easy_getinfo(3)'s CURLINFO_REDIRECT_URL(3) option instead of using CURLOPT_FOLLOWLOCA-
TION(3).
DEFAULT
0, disabled
PROTOCOLS
HTTP(S)
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* example.com is redirected, so we tell libcurl to follow redirection */
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
curl_easy_perform(curl);
}
AVAILABILITY
Along with HTTP
RETURN VALUE
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
