用于PHP的Bing Image搜索API v5.0示例

Question

I'm trying, without success, to get some results using Bing's Image search API without HTTP/Request2.php component (as used in the official examples).

I understand that the only two required parameters to make a very primitive call are q which is the query string and the subscription key. The key must be sent using headers. After looking around I found this very simple example to send headers with PHP:

$sURL = "https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=cats";
$aHTTP = array(
    'Ocp-Apim-Subscription-Key' => 'xxxxxxx',
);
$context = stream_context_create($aHTTP);
$contents = file_get_contents($sURL, false, $context);

echo $contents;

But it does not output anything. Would you kindly help me with a very basic example of use of Bing's API?

Try using cURL

$sURL = "https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=cats";
$key = "xxxxxxx";


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $sURL); 
curl_setopt($ch, CURLOPT_TIMEOUT, '1'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 'ocp-apim-subscription-key:$key');
$content = curl_exec($ch);

echo $content;
