Question

我正在尝试使用Contacts API来检索点击response-callback.php底部的<a>的人的所有联系人。我正在使用Google App Engine，在GAE中我启用了Contacts API。我通过遵循教程得到了这段代码，所以我自己很难找到错误。我没有使用PHP或GAE或任何API。这也是我无法调试和检查某些值是否为空的原因。

当我启动网站时。我什么都没说。甚至不是我用来测试我是否可以达到响应-echback.php的回声，而H2也没有显示我只是得到一个完全白页。

的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>

响应callback.php：

<?php
session_start();

$test = 'WORKS!';

您可以使用var_dump（）查看数组google_contacts是否实际已填充。把它放在main.php中：

 <?php
var_dump($google_contacts);
?>

如果你在var_dump中得到一个输出，你可以使用一个html表和一个简单的foreach，如下所示：

<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>

</table>
