Laravel's $request->file()doesn't return the actual file content. It returns an instance of the UploadedFile-class.
Laravel$request->file()不会返回实际的文件内容。它返回UploadedFile-class 的一个实例。
You need to load the actual file to be able to convert it:
您需要加载实际文件才能对其进行转换：
$image = base64_encode(file_get_contents($request->file('image')->pat??h()));

It worked for me in the following way:
它以以下方式对我有用：
$image = base64_encode(file_get_contents($request->file('image')));
I eliminated this part ->pat??h();
我删除了这部分 ->pat??h();

$image = base64_encode(file_get_contents($request->file('image')));
$image = base64_encode(file_get_contents($request->file('image')));
Works also for me.
也适用于我。
