PHP file_get_contents“需要授权”

Question

I'm trying to fetch a file from a server that requires authentication. I have the following PHP code:

//Import categories
$url = "http://$username:$password@www.example.com";
$categoriesXML = file_get_contents($url);

var_dump($url . " > " . $categoriesXML);
return;

The output of this page is merely: string(22) "Authorization Required". I also tried with:

$context = stream_context_create(array('http' => array('header'  => "Authorization: Basic " . base64_encode("$username:$password"))));

$url = "http://www.example.com";
$categoriesXML = file_get_contents($url, false, $context);

var_dump($categoriesXML);
return;

I tried with cURL as well with the following code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

var_dump($output);
return;

The cURL returns a 301 code in the $info and the $output is empty. I'm a PHP/server newbie, what am I doing wrong?

Answer 1

The OP's problem was due to choosing the wrong HTTP auth mechanism. Setting CURLOPT_AUTH to CURLAUTH_BASIC or the more permissive CURLAUTH_ANY proved to solve the problem.
