dingo-serializer-switch's Issues

laravel 5.2 使用中间件报错

环境：laravel 5.2
在 app/Http/Kernel.php 中定义了中间件。

protected $middleware = [
    \Liyu\Dingo\SerializerSwitch::class,
];

路由文件：

$api->version('v1', [
    'namespace' => 'App\Http\Controllers\Api',
    'middleware' => 'serializer:array',
], function($api) {});

访问接口时报错

使用中间件不生效

下载安装后，在 App\Http\kernel.php 文件中路由中加入该中间件，并在api路由中设置该中间件，发现返回的数据格式并没有改变，是什么原因呢？

没有分页时pagination返回null,有分页，但是没有上一页时previous也需要返回null

当分页中没有上一页时，previous需要返回null;没有下一页时,next需要返回null.
这样可以保持dingo api接口的完整性，调用api返回数据时因为格式固定了，只需判断有没有值即可，方便使用;
建议改为：

if ($currentPage > 1) {
    $pagination['links']['previous'] = $paginator->getUrl($currentPage - 1);
} else {
    if ($lastPage > 1 && $currentPage == 1) {
        $pagination['links']['previous'] = null;
    }
}

if ($currentPage < $lastPage) {
    $pagination['links']['next'] = $paginator->getUrl($currentPage + 1);
} else {
    if ($lastPage > 1 && $currentPage == $lastPage) {
        $pagination['links']['next'] = null;
    }
}

如下图所示，当是第一页并且有多页时，previous应为null，这样返回的分页格式固定不变，变的是数据和值。
