Laravel验证允许图像或pdf

Question

我在Laravel中有一个文件输入，我希望它只允许图像或pdf。如何在控制器验证中执行此操作？

$validator = Validator::make($request->all(), [
    'image' => 'image',
]);

Answer 1

你应该make a MIME type validation：

$validator = Validator::make($request->all(), [
    'image' => 'mimes:jpeg,bmp,png,gif,svg,pdf',
]);

Answer 2

您可以针对不同的mime类型进行如下验证：

    $allowed_mimes = [
         image/gif,
         image/png,
         image/jpeg,
         image/bmp,
         image/webp,
         application/octet-stream, application/pkcs12,
         application/vnd.mspowerpoint,
         application/xhtml+xml,
         application/xml,
         application/pdf
    ];

$validator = Validator::make($request->all(), [
    'image' => $allowed_mimes,
]);
