Laravel如何保存base64数据图像

Question

我知道如何使用type="file"从HTML <form>保存普通文件

也许我能做到$request->file('avatar')->store('avatars');

事实上，我使用了一个关于image upload & drop & crop的Js包

HTML/刀片

<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>

当表单与所选图像一起提交时。

$request->file('avatar')=空

因为我在提交时进行了检查，input('avatar')将更改为type="hidden"，所以我可以使用$request->file('avatar')

然后。。。。dd($request->all());我得到

[
"_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}}

}"
]

我知道这张图片是base64格式的吗？我该如何保存？

我试过base64_decode，但没用。$avatar = base64_decode($request->input('avatar'));

修复了@gguney的问题！

主要问题是我忘记了jsondecode化身输入！

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));

Answer 1

这应该有效：

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