    function shortenUrl($longUrl)
    {
        // initialize the cURL connection
        $ch = curl_init(
            sprintf('%s/url?key=%s', GOOGLE_ENDPOINT, GOOGLE_API_KEY)
        );

        // tell cURL to return the data rather than outputting it
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        // create the data to be encoded into JSON
        $requestData = array(

        );

        curl_setopt($ch, CURLOPT_POST, true);

        // set the form content type for JSON data
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));

        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($requestData));

我想我找到了解决问题的方法.由于您要连接到使用SSL的URL,因此您需要在代码中为CURL添加一些额外的参数.请尝试以下方法:

<?php
    define('GOOGLE_API_KEY', 'GoogleApiKey');
    define('GOOGLE_ENDPOINT', 'https://www.googleapis.com/urlshortener/v1');

    function shortenUrl($longUrl)
    {
        // initialize the cURL connection
        $ch = curl_init(
            sprintf('%s/url?key=%s', GOOGLE_ENDPOINT, GOOGLE_API_KEY)
        );

        // tell cURL to return the data rather than outputting it
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        // create the data to be encoded into JSON
        $requestData = array(
            'longUrl' => $longUrl
        );

        // change the request type to POST
        curl_setopt($ch, CURLOPT_POST, true);

        // set the form content type for JSON data
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));

        // set the post body to encoded JSON data
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($requestData));

        // extra parameters for working with SSL URL's; eypeon (stackoverflow)
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

        // perform the request
        $result = curl_exec($ch);
        curl_close($ch);

        // decode and return the JSON response
        return json_decode($result, true);
    }
    if (isset($_POST['url'])) {  
    $url = $_POST['url'];
    $response = shortenUrl('$url');

    echo sprintf(
        $response['longUrl'],
        $response['id']
     );
 }
?>
