如何使用通讯录API检索所有Google联系人？

Question

我正在尝试使用Contacts API来检索单击response-callback.php底部的<a>的人员的所有联系人。 我正在使用Google App Engine，并且在GAE中启用了Contacts API。 我通过遵循教程获得了此代码，因此很难自己发现错误。 我没有使用PHP或GAE或任何API。 这也是为什么我无法调试并检查某些值是否为空的原因。

当我启动网站时。 我什么也没显示。 甚至我用来测试是否可以到达response-callback.php的回声，或者H2都没有显示我只是得到了一个完全白页。

app.yaml：

application: csimporttest
version: 1
runtime: php55
api_version: 1
threadsafe: yes

handlers:

- url: /
  script: main.php;

main.php：

<!DOCTYPE html>
<html>

<head>
</head>

<body>
<h2>Hi! Stackoverflow!</h2>
<?php include'response-callback.php';
echo "response-callback file: " $test; 
?>

</body>

</html>

response-callback.php：

<?php
session_start();

require_once 'google-api-php-client/src/autoload.php';

$test = 'WORKS!'; 

$google_client_id = 'SECRET';
$google_client_secret = 'SECRET';
$google_redirect_uri = 'SECRET';

//setup new google client
$client = new Google_Client();
$client -> setApplicationName('csimporttest');
$client -> setClientid($google_client_id);
$client -> setClientSecret($google_client_secret);
$client -> setRedirectUri($google_redirect_uri);
$client -> setAccessType('online');

$client -> setScopes('https://www.googleapis.com/auth/contacts.readonly');

$googleImportUrl = $client -> createAuthUrl();
function curl($url, $post = "") {
 $curl = curl_init();
 $userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';
 curl_setopt($curl, CURLOPT_URL, $url);
 //The URL to fetch. This can also be set when initializing a session with curl_init().
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
 //TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
 curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 5);
 //The number of seconds to wait while trying to connect.
 if ($post != "") {
 curl_setopt($curl, CURLOPT_POST, 5);
 curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
 }
 curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
 //The contents of the "User-Agent: " header to be used in a HTTP request.
 curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE);
 //To follow any "Location: " header that the server sends as part of the HTTP header.
 curl_setopt($curl, CURLOPT_AUTOREFERER, TRUE);
 //To automatically set the Referer: field in requests where it follows a Location: redirect.
 curl_setopt($curl, CURLOPT_TIMEOUT, 10);
 //The maximum number of seconds to allow cURL functions to execute.
 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
 //To stop cURL from verifying the peer's certificate.
 $contents = curl_exec($curl);
 curl_close($curl);
 return $contents;

if(isset($_SESSION['google_code'])) {
 $auth_code = $_SESSION['google_code'];
 $max_results = 200;
    $fields=array(

    $xmlresponse =  curl($url);
    $contacts = json_decode($xmlresponse,true);

 $return = array();
 if (!empty($contacts['feed']['entry'])) {
 foreach($contacts['feed']['entry'] as $contact) {
           //retrieve Name and email address  
 $return[] = array (
 'name'=> $contact['title']['$t'],
 'email' => $contact['gd$email'][0]['address'],
 );
 } 
 }

 $google_contacts = $return;

 unset($_SESSION['google_code']);

}
?>
<a href="<?php echo $googleImportUrl; ?>"> Import google contacts </a>

您可以使用var_dump（）查看google_contacts数组是否真正被填充。 把它放在main.php中：

 <?php
var_dump($google_contacts);
?>

如果在var_dump中获得输出，则可以使用html表和简单的foreach，请看下面：

<table border='1' class="table table-striped table-condensed">
<thead>
<tr>
    <th>Naam </th>
    <th>Email </th>
</tr>
</thead>
<tbody>
<?php
foreach ($google_contacts as $contacts){
    echo'<tr>';
    echo'<td>'. $contacts['name']."</td>";
    echo'<td>'. $contacts['email'].'</td>';
    echo'</tr>';
}
?>
</tbody>
