Laravel 5 - VerifyCsrfToken.php 第 67 行中的 TokenMismatchException

Question

我正在尝试使用 Laravel 5.2

通过表单上传视频和图像

当只上传图片时，它可以正常工作，但是当我尝试上传视频时，它只会抛出 TokenMismatchException in VerifyCsrfToken.php line 67 错误。

我的表单确实有隐藏的 csrf_field {!! csrf_field() !!} 我的路线在 Route::group(['middleware' => ['web']], function () { }

我只是不明白为什么这不起作用。

表格：

    <form action="{{ url('admin-backend/video') }}" method="POST" enctype="multipart/form-data">
        {!! csrf_field() !!}
        <input type="text" class="form-control" name="name" placeholder="Name">
        <textarea name="description" class="form-control" rows="8"></textarea>
        <input type="submit" value="submit">
        <input type="file" class="form-control" name="video" />
        <input type="file" class="form-control" name="feature_image" />
        <input type="file" class="form-control" name="image_1" />
        <input type="file" class="form-control" name="image_2" />
        <input type="file" class="form-control" name="image_3" />
        <input type="file" class="form-control" name="image_4" />
        <input type="file" class="form-control" name="image_5" />
        <input type="file" class="form-control" name="image_6" />
    </form>

路线：

 Route::group(['middleware' => ['web']], function () {
    Route::get('/admin-backend', function () {
        return view('backend.admin.index');
    });

    Route::get('/admin-backend/video', 'adminVideoController@index');
    Route::get('/admin-backend/video/create', 'adminVideoController@create');
    Route::post('/admin-backend/video', 'adminVideoController@store');
    Route::get('/admin-backend/video/{id}', 'adminVideoController@show');
    Route::get('/admin-backend/video/{id}/edit', 'adminVideoController@edit');
    Route::put('/admin-backend/video/{id}', 'adminVideoController@update');
});

控制器 store() 方法：

public function store(Request $request)
{

    $fields = Video::prepareVideoUpload($request);

    $video = Video::create($fields);

    return view('backend.admin.videos.create');

}

视频模型：

protected $table = 'videos';

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = [
    'name','description','feature_image','image_1','image_2','image_3','image_4','image_5','image_6','video','created_at','updated_at'
];


/**
 * @param $request
 * @return array
 *
 * This function prepares the video upload by placing all relevant data into the $fields array.
 * It creates the necessary folder structure to place the images and video for each shoot
 *
 */
public static function prepareVideoUpload($request)
{
    $fields = []; //This will be used to store the information in the database instead of request
    $fields['name'] = $request['name'];
    $fields['description'] = $request['description'];


    $videoPath = public_path() . '/videos/' . substr(date("Y/m/d"),0,7); // videoPath looks like - /Applications/MAMP/htdocs/website/public/videos/2016/04
    $name = str_replace(' ', '-', $request['name']);
    $newVideoPath = $videoPath . '/' . $name;


    //if the folder is already created just make the new video name folder
    if( is_dir( $videoPath ) ) {
        mkdir($newVideoPath);
    }else{
        //create the folder structure /year/month/video-name
        mkdir($newVideoPath, 0777, true);
    }


    //Create the video and images folders for the individual shoot
    mkdir($newVideoPath . '/video');
    mkdir($newVideoPath . '/images');


    //If the video was uploaded successfully, move it to the images directory
    if ($request->hasFile('video') && $request->file('video')->isValid()) {
        $request->file('video')->move($newVideoPath . '/video',$request->file('video')->getClientOriginalName());
        $fields['video'] = 'videos/' . substr(date("Y/m/d"),0,7) . '/' . $name . '/video/' . $request->file('video')->getClientOriginalName();
    }


    //If the feature image was uploaded successfully, move it to the images directory
    if ($request->hasFile('feature_image') && $request->file('feature_image')->isValid()) {
        $request->file('feature_image')->move($newVideoPath . '/images',$request->file('feature_image')->getClientOriginalName());
        $fields['feature_image'] = 'videos/' . substr(date("Y/m/d"),0,7) . '/' . $name . '/images/' . $request->file('feature_image')->getClientOriginalName();

    }


    for($i=1;$i < 7; $i++){
        //If the image was uploaded successfully, move it to the images directory
        if ($request->hasFile('image_' . $i) && $request->file('image_' . $i)->isValid()) {
            $request->file('image_' . $i)->move($newVideoPath . '/images',$request->file('image_' . $i)->getClientOriginalName());
            $fields['image_' . $i] = 'videos/' . substr(date("Y/m/d"),0,7) . '/' . $name . '/images/' . $request->file('image_' . $i)->getClientOriginalName();
        }
    }

    return $fields;

}

到目前为止，我还没有进行任何验证，所以当我尝试在没有视频的情况下上传时，它可以工作并保存到文件夹中，并将文件夹路径输出到数据库中。但是，当我尝试用它上传视频时，它会引发错误。

我有点卡在这里，有人有什么想法吗？

Answer 1

我的猜测是您达到了 POST 数据的最大大小限制，这导致它只删除输入。

您可以将您的网络服务器和 php 调整到更高的限制，看看是否有帮助。

post_max_size 在 php.ini 中是一个不错的起点。
