Laravel中表单提交数据到另一页面，显示空白？？

Question

模板：

<form class="ui form {{ $errors->any() ? 'error' : '' }}" action="{{ url('book/store') }}" method="POST" enctype="multipart/form-data">    
           <div class="ui grid">
                <div class="four wide computer column">
                    <input type="file" name="book[cover]" class="dropify" data-default-file=""
                           data-allowed-file-extensions="jpg png jpeg"/>
                </div>
                <div class="twelve wide computer column">
                    {{ method_field('PUT') }}
                    {{ csrf_field() }}
                    @include('common.formmessage')
                    <div class="two fields">
                        <div class="field">
                            <label>图书名称</label>
                            <input type="text" name="book[title]" value="{{ old('title') }}" placeholder="请输入图书名称">
                        </div>
                        <div class="field">
                            <label>作者名称</label>
                            <input type="text" name="book[author]" value="{{ old('author') }}" placeholder="请输入作者姓名">
                        </div>
                    </div>
                    <div class="field">
                        <label>图书简介</label>
                        <textarea rows="4" name="book[desc]"></textarea>
                    </div>
                    <div class="field">
                        <div id="editor">
                            <p>在这里输入图书主要内容</p>
                        </div>
                    </div>
                    <button class="ui green button" type="submit">确认发布</button>
                    <a class="ui red button" href="javascript:history.back()">返回</a>
                    <textarea name="book[content]" id="content" style="display: none"></textarea>
                </div>
            </div>
        </form>

控制器：

 public function store(Request $request)
    {
        //
        $res = $request->input('book');
        var_dump($res);die;
        $data = $request->only([
            'title','author','desc','cover','content'
        ]);
        $file = $request->file('cover');
        if($file){
            $cover_path = $request->store('public/book');
            $data['cover']=Storage::url($cover_path);
        }
        Book::create($data);

        return back()->with('success','添加成功!');
    }

路由：

Route::get('/book/store','BookController@store');

Answer 1

路由定义的 get ，表单里是 POST ，肯定不行。
