Receiving HTTP header 406 error

问题

I am trying to invoke http://dbpedia.org/page/Los_Angeles in PHP with HTTP headers for an educational assignment I have been given. It must be this URL i.e. I am not allowed to use the JSON URL directly.

<?php
// Create a stream
$opts = array(
    'http'=>array(
    'method'=>"POST",
    'header'=>"Accept: application/json"
    )
);

$context = stream_context_create($opts);
$url = "http://dbpedia.org/page/Los_Angeles";
$data = file_get_contents($url,false,$context);
echo $data;
?>

I'm facing this error:

Warning: file_get_contents(http://dbpedia.org/page/Los_Angeles): failed to open stream: HTTP request failed! HTTP/1.1 406 Unacceptable.

Please help to get rid of this error. Note: I read about this error and found suggestions to use CURL. However, I don't want to go into installation of CURL. Kindly suggest using file_get_contents.

回答1:

406 says that application/json is not available.

From Wikipedia:

406 Not Acceptable The requested resource is only capable of generating content not acceptable according to the Accept headers sent in the request.

<?php
    $url = "http://dbpedia.org/page/Los_Angeles";
    $data = file_get_contents($url);
    echo $data;
?>
