php - 必应搜索 API 演示密钥是否有任何限制？

Question

Bing Search API（图像）演示密钥是否有任何限制？在测试页面（https://azure.microsoft.com/ru-ru/services/cognitive-services/bing-image-search-api/）上，搜索短语会产生很多结果，但在我的脚本中有根本没有结果。这是脚本本身：

function getImages($query) {
    $query = str_replace(' ', '+', $query);
    $url = 'https://api.cognitive.microsoft.com/bing/v7.0/images/search?q=' . $query . '&safesearch=strict';
    $curl = curl_init();

    curl_setopt($curl, CURLOPT_URL, $url); 
    curl_setopt($curl, CURLOPT_TIMEOUT, '1'); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'Content-Type: multipart/form-data',
        'Ocp-Apim-Subscription-Key: KEY'
    ));

    $result = curl_exec($curl);
    $result = json_decode($result, true);

    return $result['value'];
}
