You are getting empty response because PHP have some security restrictions against PUT. But Laravel have a workaround for this.
So, to solve this you have to send a POSTrequest from Postman instead, with a POSTparam __methodwith value PUT. And it should work.
您得到的是空响应，因为 PHP 对PUT. 但是 Laravel 有一个解决方法。
因此，要解决此问题，您必须改为POST从 Postman发送请求，并使用值为的POST参数。它应该工作。__methodPUT

Laravel cheats because html forms only support GET and POST, but it does understand a real PUT/PATCH request.
Laravel 会作弊，因为 html 表单只支持 GET 和 POST，但它确实理解真正的 PUT/PATCH 请求。
The problem looks like lies in Symfony it can't parse the data if it's multipart/form-data, as an alternative try using x-www-form-urlencoded content disposition.
问题似乎出在 Symfony 中，如果它是 multipart/form-data，则无法解析数据，作为替代尝试使用 x-www-form-urlencoded content disposition。

public function putUpdate(Request $request, $id){
print_r($request->all()); exit;
}
And change route too,
也改变路线，
Route::put('vehicletypes/{id}','API\VehicletypeController@putUpdate');

Why nobody is giving clear explanation at first put method field of
为什么没有人首先给出明确的解释 put 方法字段
{{method_field('put')}}
as your router uri is that is displayed using command
因为您的路由器 uri 是使用命令显示的
php artisan router:list
of update method is put/patch so first add
更新方法是 put/patch 所以首先添加
{{method_field('put')}}
and field in your form should be the same
和表单中的字段应该相同
<form action="{{route('posts.update',$post->id)}}" method="post">
after adding the csrf_toke form will be working. and final shape would be as below of form.
添加 csrf_toke 表单后将起作用。最终形状如下表所示。
<form action="{{route('posts.update',$post->id)}}" method="post" >
{{method_field('put')}}
<input type="hidden" name="_token" value="{{csrf_token()}}">
<!-- Name input-->
<div class="form-group">
<label class="col-md-3 control-label" for="name">Title</label>
<div class="col-md-9">
<input id="name" name="title" type="text" value="{{$post->title}}" class="form-control">
</div>
</div>
<!-- Message body -->
<div class="form-group">
<label class="col-md-3 control-label" for="body">
Body</label><br>
<div class="col-md-9">
<textarea class="form-control" id="message" name="body" rows="5">
{{$post->body}}
</textarea>
</div>
</div>
<!-- Form actions -->
<div class="form-group">
<div class="col-md-9 text-right col-md-offset-3">
<button type="submit" class="btn btn-success btn-lg">Update</button>
<a href="{{Route('posts.index')}}" type="button" class="btn btn-primary btn-lg">Cancel</a>
</div>
</div>
</form>

Checked "x-www-form-urlencoded" instead of "form-data" under body tab in the Postman, the put methood will work as well...
在 Postman 的 body 选项卡下检查了“x-www-form-urlencoded”而不是“form-data”，put 方法也可以工作......

Following link will resolve the issue to get the request form data plus the images.
If you are working on Laravel, you can easily parse and bind the form params in the \Illuminate\Http\Request Instance
以下链接将解决获取请求表数据和图像的问题。
如果您正在使用 Laravel，您可以轻松解析和绑定 \Illuminate\Http\Request Instance 中的表单参数
Simply just get the ParseInputStream Class from the link below:
Class ParseInputStream.php
只需从下面的链接中获取 ParseInputStream 类：
Class ParseInputStream.php
Create another Validation Rule Class in Laravel optional but not required,
在 Laravel 中创建另一个验证规则类可选但不是必需的，
class NoteUpdateRequest extends Request {
public function all($keys = null)
{
if(strtolower($this->getMethod())=='put' && preg_match('/multipart\/form-data/', $this->headers->get('Content-Type')) or
preg_match('/multipart\/form-data/', $this->headers->get('content-type')))
{
$result = [];
new ParseInputStream($result);
$result = array_merge($result, $this->route()->parameters());
$this->request->add($result);
}
return parent::all($keys);
}
public function rules()
{
dd($this->all());
return [
'noteId' => 'required|integer|exists:notes,id',
'title' => 'required|string|max:200',
'note' => 'required|string|min:10|max:2000'
];
}
}
I hope it resolved what you want to achieve, using PUT or PATCH method along with Form Params
我希望它解决了您想要实现的目标，使用 PUT 或 PATCH 方法以及 Form Params
