它是如何工作的？

Sioner Metadata Extractor 可以在运行完全指定的秒数（稍后解释）之前，快速运行搜索以获取指定的数据，并获取这些数据而无需使用 JavaScript，从而节省其执行时间。为此，只需将您想要获取的数据作为第一个验证的必需参数 #4 传递即可。

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, null, null, ['website', 'title', 'image', 'description']);

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);

但如果这样没有发生，它将使用 JavaScript 运行浏览器以获取数据。默认运行时间为 3 秒，但您可以通过设置参数 #2 来更改此值。

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, 2.5); //2.5 seconds

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);

我们默认获取 200x200 的 og:image，如果找不到，则返回下一个比该尺寸更大的图像。如果没有匹配项，则返回最大的。但您也可以设置这些值。

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, null, [250,300]); //250 width, 300 height

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);

这样，您可以传递您想要的参数并构建您想要的方式。观看

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, 5, [500,100], ['website', 'title', 'image', 'description']);

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);
