Laravel：上传 64base 图片而不是普通图片

问题描述

我有一个使用 React 和 Laravel 的应用程序，用于上传图片。 我正在使用 Laravel Image Intervention package。

在测试我的 API 时，正常图像的上传工作正常。

使用 React，用户可以从他的电脑中选择一个图像并进行裁剪，然后他会看到预览为生成的裁剪 64base 图像。

我想将生成的 64base 图像上传到我的数据库而不是普通图像，该怎么做？

Fileupload controller

 public function Store(Request $request)
    {
 $this->validate($request,[
 'filename' => 'image|required|mimes:jpeg,png,jpg,gif,svg'
 ]);
 $originalImage= $request->file('filename');
 $thumbnailImage = Image::make($originalImage);
 
 // Define upload path
 $originalPath = public_path('/images/');
 
 // Save Orginal Image
 $thumbnailImage->save($originalPath.time().$originalImage->getClientOriginalName());
 
 // Save In Database
 $imagemodel= new Photo();
 $imagemodel->photo_name=time().$originalImage->getClientOriginalName();
 $imagemodel->save();
 
 return back()->with('success','Image Upload successful');
 
    }

解决方法

这个应该可以用

可能的替代方案：

$folderPath = "images/";

$image_parts = explode(";base64,",$request->file('file'));
$image_type_aux = explode("image/",$image_parts[0]);
$image_type = $image_type_aux[1];
$image_base64 = base64_decode($image_parts[1]);
$file = $folderPath . uniqid() . '. '.$image_type;

// file_put_contents($file,$image_base64);
Storage::put($file,$image_base64);
