如何使用Contacts API檢索所有Google聯繫人？

我試圖使用Contacts API來檢索點擊Response-callback.php底部的<a>的人的所有聯繫人。我正在使用Google App Engine，並且在GAE中啓用了聯繫人API。我通過遵循一個教程得到了這段代碼，所以很難自己發現錯誤。我沒有使用PHP或GAE或任何API。這也是爲什麼我無法調試並檢查某些值是否爲空值的原因。如何使用Contacts API檢索所有Google聯繫人？

當我啓動網站。我什麼都沒有顯示。甚至沒有我使用的回聲來測試我是否可以訪問response-callback.php，H2也沒有顯示我只是獲得了一個完全白頁。

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>

響應callback.php：

全白頁？那將是_White死亡屏幕_。請參閱[此問題]（http://stackoverflow.com/questions/2914127/white-screen-of-death）的答案以獲取可能的解決方案。 –

您可以使用的var_dump（），看是否數組google_contacts實際上是填充的。將這個在main.php：

<?php 
var_dump($google_contacts); 
?>

如果你在的var_dump的輸出，你可以使用HTML表格和一個簡單的foreach，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> 

</table>
