Laravel如何保存base64数据图片?

Laravel how to save the base64 data image?

我知道如何使用 type="file"

保存来自 HTML <form> 的普通文件

也许我可以做到 $request->file('avatar')->store('avatars');

其实我用的是一个Js包关于一个image upload & drop & crop

HTML / Blade

<form action="{{route('avatar.update')}}" method="POST" enctype="multipart/form-data" id="avatar">
<div class="slim rounded-2xl "
      data-label="Select your Avatar"
      data-size="400,400"
      data-ratio="1:1">
    <input type="file" name="avatar" >
</div>
<button type="submit"> Update </button>
</form>

当表单提交时选择了一张图片。

$request->file('avatar') = 空

因为我在提交的时候检查,input('avatar')会变成type="hidden",所以我可以用$request->file('avatar')

那么…… dd($request->all()); 我得到了



[
  "_token" => "od91HbEuWSbgx5gqfaNOeHQIC8qUBMumzf7u4Dvr",
  "avatar" => "{
      "server":null,
      "meta":{},
    
      "input":{"name":"ccc.png","type":"image/png","size":1412200,"width":2860,"height":1440,"field":null},
    
      "output":{"name":"ccc.png",
                "type":"image/png",
                "width":400,"height":400,
                "image":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUCC....etc"},
      
      "actions":{"rotation":null,"crop":{"x":710,"y":0,"height":1440,"width":1440,"type":"auto"},"size":{"width":400,"height":400},"filters":{"sharpen":0},"minSize":{"width":0,"height":0}}
    
    }"
]

我得到的这张图片是base64格式的?我怎样才能保存它?

我尝试 base64_decode 但没有用。 $avatar = base64_decode($request->input('avatar'));

解决了来自@gguney 的问题!

主要问题是忘记json_decode头像输入了!

控制器代码现在


        $image = json_decode($request->input('avatar'))->output->image;
        $imageName = time() . 'ava.png';

        $image = str_replace('data:image/png;base64,', '', $image);
        $image = str_replace(' ', '+', $image);
        Storage::disk('temp_avatar')->put($imageName, base64_decode($image));

这应该有效:

json_decode($request->input('avatar'))->output->image
