Laravel 5 干预中的图像验证

感谢@maytham为我指出了正确的方向.

我发现图像干预本身不会进行任何验证.所有图像验证都必须在将其传递给图像干预进行上传之前完成.由于Laravel内置了image和mime类型的验证器，这使得图像验证非常容易.这就是我现在所拥有的，在将文件输入传递给图像干预之前，我首先验证文件输入.

Validator Check Before Processing Intervention Image Class:

 Route::post('/upload', function()
 {
    $postData = $request->only('file');
    $file = $postData['file'];

    // Build the input for validation
    $fileArray = array('image' => $file);

    // Tell the validator that this file should be an image
    $rules = array(
      'image' => 'mimes:jpeg,jpg,png,gif|required|max:10000' // max 10000kb
    );

    // Now pass the input and rules into the validator
    $validator = Validator::make($fileArray, $rules);

    // Check to see if validation fails or passes
    if ($validator->fails())
    {
          // Redirect or return json to frontend with a helpful message to inform the user 
          // that the provided file was not an adequate type
          return response()->json(['error' => $validator->errors()->getMessages()], 400);
    } else
    {
        // Store the File Now
        // read image from temporary file
        Image::make($file)->resize(300, 200)->save('foo.jpg');
    };
 });

希望这能帮上忙.
