CURLOPT_HEADER returns 401

Posted on 2014-09-25
Last Modified: 2014-10-01
I need to get the location header. From what I've read, this should be as simple as

curl_setopt($c, CURLOPT_HEADER, true);
curl_setopt($c, CURLOPT_FOLLOWLOCATION, false);

Open in new window

If I don't include those two options, the curl request works fine, but I'm not able to get the location header.

If I do include those two options, then I get a 401 error.

The Location that is being returned should be a URL that does require an additional login. What am I doing wrong?

The 401 code isn't an error. It's just the code that tells the browser to prompt for authentication. Are you looking for a URL that happens AFTER login?

By themselves, these two instructions don't tell us much.  What is the URL you're making the request to?  Why are you telling cURL not to follow the location headers?

In generating the needed information for a response, I figured out my issue. I wasn't thinking about previous requests. Looking too much at the trees to see the forest.

I have to make a call to get a session token and then use that session token to make my PUT call. Since I wasn't parsing out the headers from the previous request, I wasn't successfully grabbing the session token. Everything is working now.

The issue was a previous request. I didn't have enough information in the question to allow others to provide an answer and once I got that information, I was able to find the solution.
