Question

当我点击main.php中的<a>导入联系人时，我点击谷歌的接受，所以我允许他们查看我的联系人。然后当我回到自己的页面时...它根本没有显示任何联系人。我想这是因为我没有回复任何联系，但我不知道如何。

的app.yaml：

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

handlers:
- url: /.*
  script: main.php

main.php：

    <!DOCTYPE html>
    <html>

    <head>
    </head>

    <body>
    <h2>Hi!</h2>

    <?php include('response-callback.php');?>

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

    </body>

    </html>

响应callback.php;

<?php

Answer 1

代码执行的最后一件事就是设置＆＃39; $ google_contacts = $ return＆＃39;，因此您可以使用$ google_contacts数组对您的应用做一些有用的事情，例如显示它。 blog where this code originated并未提及代码示例显示任何内容，只是它是如何检索联系人的示例。

Answer 2

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>

我的网站不会显示任何联系人？
