【问题描述】：
我对图像或 mime 的整体验证有疑问。
这是我的代码：
$this->validate($request, [
'title' => 'required|max:50',
'content' => 'required|min:20',
'description' => 'required|max:140',
'file' => 'image'
]);
当我尝试上传任何文件时出现错误：
文件上传失败。
当我没有 image 标志时，一切正常。
我可以输入required 或max:5000 之类的内容。
我查看了文档，它应该可以工作，但它没有。
那我做错了什么？
编辑：
添加表格：
{!! Form::open(['method' => 'POST', 'action' => 'PostController@store', 'files' => 'true' ]) !!}
<div class="form-group">
{!! Form::label('title', 'Title:') !!}<br>
{!! Form::text('title', null, ['class' => 'form-control']) !!}
<small>Max 50 characters</small>
<br>
{!! Form::label('description', 'Description:') !!}<br>
{!! Form::textarea('description', null, ['class' => 'form-control', 'rows' => 2, 'cols' => 50]) !!}
<small>Max 140 characters</small>
<br>
{!! Form::label('content', 'Content:') !!}<br>
{!! Form::textarea('content', null, ['class' => 'form-control', 'id' =>'content', 'rows' => 8, 'cols' => 50]) !!}
<br>
{!! Form::label('file', 'Upload a thumbnail here:') !!} <br>
{!! Form::file('file', null, ['class' => 'form-control']) !!} <br>
<small>Only jpeg, png, bmp, gif, or svg</small>
</div>
{!! Form::submit(null, ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}
编辑 2：
添加了html：
<form method="POST" action="https://blog.luukwuijster.eu" accept-charset="UTF-8" enctype="multipart/form-data"><input name="_token" type="hidden" value="N72xyc8mmbdFGrS78sdhIqh25awN30AboL9ecqGm">
<div class="form-group">
<label for="title">Title:</label><br>
<input class="form-control" name="title" type="text" id="title">
<small>Max 50 characters</small>
<br>
<label for="description">Description:</label><br>
<textarea class="form-control" rows="2" cols="50" name="description" id="description"></textarea>
<small>Max 140 characters</small>
<br>
<label for="content">Content:</label><br>
<textarea class="form-control" id="content" rows="8" cols="50" name="content" style="display: none;"></textarea>
<br>
<label for="file">Upload a thumbnail here:</label> <br>
<input name="file" type="file" id="file"> <br>
<small>Only jpeg, png, bmp, gif, or svg</small>
</div>
<input class="btn btn-primary" type="submit">
</form>

添加了控制器

【问题讨论】：
-
你能把你的表格给我看看吗？
-
我已将其添加到帖子中。
-
我不知道这是否是一个问题，但可能是因为
'files' => 'true'（你在''中输入了true）。尝试更改为'files' => true、@Luuk Wuijster。向我展示您在网络源中获得的表单 -
不，这不起作用，我将 html 添加到帖子中
-
这是 FormRequest 验证还是在控制器内部？发布整个控制器或自定义表单请求将有助于故障排除。如果这是在控制器中，则应在 validate 方法中将 $request 更改为 $request->all()
