我为我的项目创建了一个加载 Google Weather API 的元素。在本地它工作得很好。当我上传它并把它交给我的朋友尝试时，问题就出现了。

元素的代码如下

<?php
Configure::write('debug', 2);

$xml = simplexml_load_file('http://www.google.com/ig/api?weather=name_city');
$information = $xml->xpath("/xml_api_reply/weather/forecast_information");
$current = $xml->xpath("/xml_api_reply/weather/current_conditions");
$forecast_list = $xml->xpath("/xml_api_reply/weather/forecast_conditions");

?>
<html>
<head>
<title>Google Weather API</title>
</head>
<body>
<h1><?= print $information[0]->city['data']; ?></h1>
<h2>Today's weather</h2>
<div class="weather">
<?php $icon_today = (string) $current[0]->condition['data'];?>

<?php echo $this->Html->image('tick/'.$icon_today.'.png');?>
        <span class="condition">
        <?= $current[0]->temp_c['data'] ?>&deg; C,

        </span>
 </div>
<h2>Forecast</h2>
    <? foreach ($forecast_list as $forecast) : ?>
    <div class="weather">
    <?php $icon = (string) $forecast->condition['data'];?>
      <?php echo $this->Html->image('tick/'.$icon.'.png',array('width' => '45'));?>

        <div><?= $forecast->day_of_week['data']; ?></div>
        <span class="condition">
        <?php
        $low = (int) $forecast->low['data'];
        $high = (int) $forecast->high['data'];
        $low_celsius = (int) (($low - 32) * (5/9));
        $high_celsius = (int)(($high - 32) * (5/9));
        ?>
            <?= $low_celsius ?>&deg; C - <?= $high_celsius ?>&deg; C,
            <?= $forecast->condition['data'] ?>
        </span>
 </div>
<? endforeach ?>
</body>
</html>

当我上传它时，我收到了这些消息

name_city具有实际价值。当我在另一台计算机上尝试时，其他类型的错误（例如$forecast->day_of_week['data']未被识别为有效变量）。似乎在线版本无法从 Google Weather 接收数据，因此结果为空。谁能告诉我该怎么做？

Google 计划关闭 iGoogle 和相关 API。从 8 月 27 日起已停止响应天气 API。您可以使用wunderground.com的 api

当前对您正在使用的 Google Weather API 有间歇性的 403 Forbidden 响应。请参阅Google Weather API 403 错误

403 响应可能导致您在结果的第一行中看到空文档。现在在本地和服务器上再次重新运行代码，看看问题是否是间歇性的。

间歇性 403 响应的原因未知，但自 2012 年 8 月 7 日以来一直存在问题，这是您发布此问题的时间。
