【问题描述】:
我正在使用 Laravel 5.6 让用户上传他们的个人资料照片。在生产中,我遇到了一些返回错误的案例
无法从给定的二进制数据初始化。
最近 2,000 个用户上传的内容中有 5 个错误 (0.25%)。很低,但这些用户是我想保留的重要用户。
我使用 Dropzone 作为前端,仅通过 Ajax Post 将图像数据发送到控制器。
这里是控制器:
public function savePhotos(Request $request) {
if(!$_FILES["file"]["error"]){
$file = $request->file('file');
$ext = $file->getClientOriginalExtension();
$filename = Auth::user()->id . '.' . $ext;
$filePathAndName = 'uploaded/'.$filename;
Storage::disk('original_images')->put($filePathAndName, file_get_contents($file -> getRealPath()));
//generate thumbnail
try{
$img = Image::make(Storage::disk('original_images')->get($filePathAndName));
$img->orientate()->fit(200, 240);
$newImg=Image::canvas(200, 240, '#ffffff')->encode('jpg',75); //create a blank image 200x240 px with white background
$newImg->insert($img, 'center'); //paste resized img to new blank image
Storage::disk('thumb_images')->put($filePathAndName, (string) $newImg->encode());
} catch (ErrorException $e) {}
}
}
错误发生在Image::make() 处,即使它在try catch 块中。我检查了所有上传的文件,这里有2个错误。
-
部分入门级安卓手机上传0字节图片。
-
iPhone (iOS13/Safari) 上传图像,我可以从服务器下载它们,并在我的 Windows 机器上查看。但是 Laravel 不知何故无法处理它们,并返回上述错误。
对于那些从 iPhone 上传的图片,我无法分享它们,因为它是上传者的面部。不能违反隐私法。相反,我可以分享 exif。两者都是 .JPEG。
