代理localhost上的cURL返回访问被拒绝

Question

I'm trying to access a .php file from another .php using cURL .

Both are on localhost and I'm using a proxy .

THE PROBLEM

If I try to access using postman or direct on the browser, the desired file returns correctly.

However, everytime that I try to access this file from another .php file using cURL , and passing all the proxy and auth values, it gives me the following:

Access Denied (authentication_failed)

Your credentials could not be authenticated: "Credentials are missing.". You will not be permitted access until your credentials can be verified. This is typically caused by an incorrect username and/or password, but could also be caused by network problems.

For assistance, contact your network support team.

Her is my cURL:

$curl = curl_init();

curl_setopt_array($curl,array(
    CURLOPT_PROXY => "proxy.myspecificproxy.com.br",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_URL => "localhost/MyDesiredFile.php?param=test&mail=test%40test.com",
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_PROXYUSERPWD => "myuser:mypassword123",
    CURLOPT_PROXYPORT => "8080",
    CURLOPT_PROXYTYPE => 'HTTP',
));


$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

Any ideas?

EDIT :

Beyond trying to access via postman or browser, if I cURL directly from the command line, it works too.

EDIT

Tried to disable the proxy for local addresses , but no change in the result.

Answer 1

Is there a redirect involved? Remember that cURL doesn't follow redirects unless you tell it to, by passing the --location flag.

Does it work if you run it from the command line? Try that, and try passing --verbose and --include to see the returned headers.

Update your code as below

$curl = curl_init();

curl_setopt_array($curl,array(
    CURLOPT_PROXY => "proxy.myspecificproxy.com.br",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_URL => "localhost/MyDesiredFile.php?param=test&mail=test%40test.com",
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_PROXYUSERPWD => "myuser:mypassword123",
    CURLOPT_PROXYPORT => "8080",
    CURLOPT_PROXYTYPE => 'HTTP',
));


$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

<?php
$curl = curl_init();

curl_setopt_array($curl,array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_URL => "http://localhost/",
    CURLOPT_FOLLOWLOCATION => true,
));


$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

Looks like it was a misconfiguration in the privileges.

I contacted the support team of the company and the problem was solved.
