客户端将文件发送到服务器。它看起来像这样：
array:1 [▼
"file" => array:5 [▼
"name" => "MMM1(one row).TXT"
"type" => "application/octet-stream"
"tmp_name" => "/tmp/phpaKnJzE"
"error" => 0
"size" => 1365
]
]
如果要进行以下操作：
dd($_FILES);
我试图像处理这样的文件：
foreach ($_FILES["file"] as $file) {
$file->store('tests');
$file->getClientOriginalName();
}
但它对我不起作用。
它有一个错误：
在数组
上调用成员函数getClientOriginalName（）$this->file->getClientOriginalName()

如果您要上传图片，那么您也可以使用intervention/image套餐。
使用它，您还可以进行基本的图像处理。
在您的控制器发布操作中执行以下操作：
use Intervention\Image\Facades\Image;
if($request->hasFile('image')){
$image = \Image::make( $request->file( 'image' ) );
$image->save( storage_path('images/'. $request->file('image')->getClientOriginalName()));
}
