Data URI包提供了一种从数据URI字符串创建文件或将文件转换为数据URI字符串的接口。它提供了一个对象，作为将原始字符串或文件转换为数据URI的桥梁。

用法

数据URI对象提供了从文件路径或HTTP URL创建对象的方法

• 从路径创建

// We assume file exists at path specified below
$path = __DIR__ . 'storage/file.txt';
$object = \Drewlabs\DataURI\DataURI::create($path);

// Converting $object to data uri string
$uri = $object->__toString();
// or using type casting
$uri = (string)$object;

• 从HTTP URL创建

$url = 'https://i.picsum.photos/id/237/200/300.jpg?hmac=TmmQSbShHz9CdQm0NkEjx1Dyh_Y984R9LpNrpvH2D_U';
$object = \Drewlabs\DataURI\DataURI::createFromURL($url);

// Converting $object to data uri string
$uri = $object->__toString();
// or using type casting
$uri = (string)$object;

• 从URI字符串创建

该包附带了一个解析类，可以将URI字符串转换为二进制文件或文本文件，这些文件可以写入存储。

$uri = 'data:application/vnd.openxmlformats-officedocument.wordprocessingml.document;base64,UEsDBBQABgAIAAAAIQCQyAt3kAEAADEHAAATAAgCW0NvbnRlbnRfVHlwZXNdLnhtbCCiBAIooAACAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAC0lUlrwzAQhe+F/geja4mV9FBKiZNDl2MbaAu9KtI4EdWGNNn...';

$parser = new \Drewlabs\DataURI\Parser();
$object = $parser->parse($uri); // Creates instance of \Drewlabs\DataURI\DataURI

API

• getContent()

返回存储在{@see \Drewlabs\DataURI\DataURI}对象内部的编码的二进制内容。

• getMimeType()

返回文件MIME类型。目前支持常用Web MIME类型。

• isBinary()

如果URI信息是二进制内容，则返回true。

• getExtension()

使用MIME类型猜测文件扩展名。
