file_get_contents默认使用哪个HTTP版本？

Question

Recently, one of our service providers sent this update to their service:

using the HTTP 1.0 protocol:
API calls will return HTTP/1.0 400 Bad Request ... should update their code to HTTP 1.1 and include the Host header in the API request.

Does PHP's file_get_contents() do all that by default?

Answer 1

You can pass a stream_context to file_get_contents like the code below:

<?php
// Create a stream
$opts = array(
  'http'=>array(
    'method'=>"GET",
    'header'=>"Accept-language: en
" .
              "Cookie: foo=bar
"
  )
);

$context = stream_context_create($opts);

// Open the file using the HTTP headers set above
$file = file_get_contents('http://www.example.com/', false, $context);
?>

You can find more in the PHP manual at: http://us.php.net/file_get_contents

Hope it helps.
