php - 是否可以从 Google Play 获取应用程序的下载次数？

Question

我正在尝试获取已上传到 Google Play 的应用程序的下载次数。

我正在寻找一个 API(或类似的东西)，它可以通过用户身份验证为我检索下载次数。我不想要第三方应用程序(如 AppAnnie)。

如果它可以在 PHP 上运行，那就太好了，我发现有一个库，我认为它是我能找到的最接近从 Google 应用程序获取数据的 API。

Google APIs Client Library for PHP

但我找不到任何提及 Google Play 的应用程序。

有没有什么方法可以下载具有身份验证 key 的特定应用程序？

提前致谢!

使用 google-play-scraper获取应用程序信息的库如下:

示例:

$app = $scraper->getApp('com.mojang.minecraftpe');

结果:

array (
  'id' => 'com.mojang.minecraftpe',
  'url' => 'https://play.google.com/store/apps/details?id=com.mojang.minecraftpe',
  'image' => 'https://lh3.googleusercontent.com/30koN0eGl-LHqvUZrCj9HT4qVPQdvN508p2wuhaWUnqKeCp6nrs9QW8v6IVGvGNauA=w300',
  'title' => 'Minecraft: Pocket Edition',
  'author' => 'Mojang',
  'author_link' => 'https://play.google.com/store/apps/developer?id=Mojang',
  'categories' => array (
    'Arcade',
    'Creativity',
  ),
  'price' => '$6.99',
  'screenshots' => array (
    'https://lh3.googleusercontent.com/VkLE0e0EDuRID6jdTE97cC8BomcDReJtZOem9Jlb14jw9O7ytAGvE-2pLqvoSJ7w3IdK=h310',
    'https://lh3.googleusercontent.com/28b1vxJQe916wOaSVB4CmcnDujk8M2SNaCwqtQ4cUS0wYKYn9kCYeqxX0uyI2X-nQv0=h310',
    // [...]
  ),
  'description' => 'Our latest free update includes the Nether and all its inhabitants[...]',
  'description_html' => 'Our latest free update includes the Nether and all its inhabitants[...]',
  'rating' => 4.4726405143737793,
  'votes' => 1136962,
  'last_updated' => 'October 22, 2015',
  'size' => 'Varies with device',
  'downloads' => '10,000,000 - 50,000,000',
  'version' => 'Varies with device',
  'supported_os' => 'Varies with device',
  'content_rating' => 'Everyone 10+',
  'whatsnew' => 'Build, explore and survive on the go with Minecraft: Pocket Edition[...]',
  'video_link' => 'https://www.youtube.com/embed/D2Z9oKTzzrM?ps=play&vq=large&rel=0&autohide=1&showinfo=0&autoplay=1',
  'video_image' => 'https://i.ytimg.com/vi/D2Z9oKTzzrM/hqdefault.jpg',
)

编辑:轻松获取下载计数如下:

echo $app['downloads']; // Outputs: '10,000,000 - 50,000,000'

或者如果你想要左边的值:

$matches = null;
$returnValue = preg_match('/.*(?= -)/', '10,000,000 - 50,000,000', $matches);
echo $matches[0]; // Outputs: '10,000,000'

或者如果你想要正确的值:

$matches = null;
$returnValue = preg_match('/(?<=- ).*/', '10,000,000 - 50,000,000', $matches);
echo $matches[0]; // Outputs: '50,000,000'

然后使用以下方法轻松地将其转换为整数:

$count = null;
$returnValue = (int)preg_replace('/,/', '', $matches[0], -1, $count);
echo $returnValue; // Outputs: 10000000 or 50000000
