Ошибка получения файла PDF в локальном хранилище

Question

Я получаю строку base64 файла PDF в контроллере. Когда я сохраняю его в локальном хранилище, он показывает ошибку поврежденного PDF (не декодированного). Как я могу решить эту проблему? Может кто-нибудь выяснить?

Answer 1

Пожалуйста, попробуйте это решение для обновлений, оно определенно должно работать для вас.

$pdf = $request->get('pdf_file');
$id = $request->get('user_id');

$data = explode( ',', $pdf);

# Decode the Base64 string, making sure that it contains only valid characters
$bin = base64_decode($data[1], true);    


$file_name = time() . '-test.pdf';
$path = public_path() . '/images/users/' . $file_name;


# Write the PDF contents to a local file
file_put_contents($path, $bin);

Answer 2

 $pdf = $request->get('pdf_file');
 $id = $request->get('user_id');

 $array_1 = explode(";", $pdf);
 $array_2 = explode(",", array_1[1]);
 $data = base64_decode($array_2[1]);

 $file_name = time() . '-test.pdf';
 $path = public_path() . '/images/users/' . $file_name;

 file_put_contents($path, $data);

Попробуйте этот кусок кода. Сложно объяснить взрыв в формате base64 с помощью записи, поэтому, если вы просто dd();, вам это будет очень ясно.
