我的 php 不会做任何事情？使用联系人 API 共 google

Question

我正在尝试制作一个网站，您可以在其中从 gmail 导入联系人并将他们添加为网站内的朋友。现在我只想显示点击 <a> 的人的联系人。我遵循了一个教程，一切都应该有效，但事实并非如此。它确实在顶部显示了 <H2>，但没有显示实际上很重要的 <a>。我的 google 秘密和客户端 ID 是正确的，但我不想只显示它们。 google php API 的路径也是正确的，但我认为那里出了问题，因为它无法识别任何 php.

app.yaml:

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

handlers:

- url: .*
  script: response-callback.php

响应-callback.php：

<!DOCTYPE html>
<html><body>
<h2>ttest</h2>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

<script src="https://apis.google.com/js/client.js"></script>

Answer 1

首先，您是对的 - 从不显示您的客户端 ID 和密码。

关于您发布的内容，有很多事情不清楚，包括您如何确切地获取 google_code 会话变量集，但我建议按照以下几行进行调试：

查看 $result 的完整值。它可能会返回一个错误代码，这可能表明它没有加载联系人的原因。
仔细检查令牌 URL 端点。 https://developers.google.com/identity/protocols/OAuth2WebServer 说它应该是 https://www.googleapis.com/oauth2/v4/token，但我以前看到 URL 列出的不同，所以我不知道哪个是实际有效的。
确保您已在 Google Developers Console 中授权联系人 API，并确保在您通过授权 window 时，它会请求访问您的权限联系人。

Answer 2

您可以使用 var_dump() 来查看数组 google_contacts 是否已实际填充。把这个放在 main.php:

<?php
var_dump($google_contacts);
?>

如果您在 var_dump 中获得输出，您可以使用 html table 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>
