使用file_get_contents发布登录-不卷曲

Question

One site requires login for three variables: username, password and token. This data is sent via POST.

token is also sent through a section.

I have all three variables, and I want to log in via file_get_contents.

How can that data be sent and the authentication is successful?

    function file_post_contents()
{

    $url = 'http://site.com/auth.php?' . session_name() . '=' . session_id();

    $login = 'jhon';
    $senha = 'doe';

    $token = '123456';  
    $_SESSION["token"] = $token;

    $postdata = http_build_query(
        array(
            'login' => $login,
            'senha' => $senha,
            'token' => $token, 
                            $_SESSION["token"] => $token
        )
    );

    $opts = array('http' =>
        array(
            'method'  => 'POST',
            'header'  => 'Content-type: application/x-www-form-urlencoded',
            'content' => $postdata
        )
    );

    if($login && $senha)
    {
        $opts['http']['header'] = ("Authorization: Basic " . base64_encode("$login:$senha"));
    }

    $context = stream_context_create($opts);
    return file_get_contents($url, false, $context);
}

Modified code. It does not work.

    function file_post_contents()
{

    $url = 'http://site.com/auth.php?' . session_name() . '=' . session_id();

    $login = 'jhon';
    $senha = 'doe';

    $token = '123456';  
    $_SESSION["token"] = $token;

    $postdata = http_build_query(
        array(
            'login' => $login,
            'senha' => $senha,
            'token' => $token
            //, $_SESSION["token"] => $token
        )
    );

    $opts = array('http' =>
        array(
            'method'  => 'POST',
            'header'  => 'Content-type: application/x-www-form-urlencoded'
             . "\r\n" . "Authorization: Basic " . base64_encode("$login:$senha"). "\r\n",
            'content' => $postdata
        )
    );


    $context = stream_context_create($opts);
    return file_get_contents($url, false, $context);
}

Answer 1

Your headers might be set wrong, try adding \\r\\n like so

$opts = array('http' =>
        array(
            'method'  => 'POST',
            'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
            'content' => $postdata
        )
    );

and later down the code

$opts['http']['header'] = $opts['http']['header'] . "Authorization: Basic " . base64_encode("$login:$senha") . "\\r\\n";

Answer 2

You're overriding $opts['http']['header'] with the Basic auth. You're not adding it to the Content-type, you're replacing Content-type with it.
