cURL with Perl

[rottmanj]

I am working on a revamp of a previous application that I have written in coldfusion. The application deals with RETS data. The issue that I am having is with using the curl option HTTP_AUTH and CURLAUTH_DIGEST .

When attempting to authenticate against the server. No matter what I try, my authentication always fails. I have made sure to validate the auth information.

In my testings, I have also verified that curl can authenticate via the command line option.

Here is my current testing code base.

 
my $curl= new WWW::Curl::easy;
$curl->setopt(CURLOPT_VERBOSE,1); 
$curl->setopt(CURLOPT_HTTPAUTH,CURLAUTH_ANY);  
$curl->setopt(CURLOPT_USERPWD, '$user:$pass'); 
$curl->setopt(CURLOPT_URL, $site);
my $retcode = $curl->perform;
 
print $retcode;
 

This is the error I receive back.

I would check, without using your script, that you can log into the website first. The error "Unauthoriz ed" is telling me you cannot.

I have already verified that I am able to log in. The Unauthorized is part of the ResponseHeaders that I receive back.

Using single quotes around variables will block the substitution of those variables(will be considered literal string). Change:

$curl->setopt(CURLOPT_USERPWD, '$user:$pass'); 
 

to

$curl->setopt(CURLOPT_USERPWD, "$user:$pass"); 
 

That's how this line should be, though this may/may not solve your issue.

I am having a heck of a time getting this to work. Every example that I have found uses pretty much what I have here.

At first glance it looks like it is trying to use Basic auth, but I know for a fact that this server uses digest auth.

As I have said before.

Verified that server uses Digest auth
Verified username and password
Verified that URI
Tried with '$user:$pass' and "$user:$pas s"

Any help with this would be greatly appreciated.

Here is the output that I get from my app.
