在我的控制器中,我有如下内容:
public function index()
{
$questions = Question::all();
return view('questions.index', compact('questions'));
}
不过,我希望我的ajax请求也能使用此路由。在这种情况下,我希望返回JSON。我正在考虑以下内容:
public function index()
{
$questions = Question::all();
return $this->render('questions.index', compact('questions'));
}
public function render($params)
{
if ($this->isAjax()) {
return Response::json($params);
} else {
return view('questions.index')->with($params);
}
}
顺便说一句,我还没有测试过这些,但希望你能明白。
然而,我想知道我是否可以更改内置视图(…)功能本身,以使事情变得更轻松。所以我只保留以下内容:
public function index()
{
$questions = Question::all();
// this function will detect the request and deal with it
// e.g. if header X-Requested-With=XMLHttpRequest/ isAjax()
return view('questions.index', compact('questions'));
}
这可能吗?
您可能想要进行自定义响应:
- 添加ResponseServiceProvider.php
namespace App'Providers;
use Request;
use Response;
use View;
use Illuminate'Support'ServiceProvider;
class ResponseServiceProvider extends ServiceProvider
{
/**
* Perform post-registration booting of services.
*
* @return void
*/
public function boot()
{
Response::macro('smart', function($view, $data) {
if (Request::ajax()) {
return Response::json($data);
} else {
return View::make($view, $data);
}
});
}
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
}
- 将"App''Providers''ResponseServiceProvider"添加到
config/app.php
中的提供商列表中:
'providers' => [
'App'Providers'ResponseMacroServiceProvider',
];
- 在控制器中使用新助手:
return Response::smart('questions.index', $data);
只需在索引方法本身中检查请求是否为Ajax请求。
public method index() {
$questions = Question::all();
if('Request::ajax())
return 'Response::json($questions);
else
return view('questions.index', compact('questions'));
}
使用Request::ajax()
,或注入请求对象:
use Illuminate'Http'Request;
class Controller {
public function index(Request $request)
{
$data = ['questions' => Question::all()];
if ($request->ajax()) {
return response()->json($data);
} else {
return view('questions.index')->with($data);
}
}
}
您的视图不应该知道任何关于HTTP请求/响应的信息。
我想简单的方法就是把一个方法放在父控制器类中:
use Illuminate'Routing'Controller as BaseController;
abstract class Controller extends BaseController {
...
protected function render($view, $data)
{
if (Request::ajax()) {
return Response::json($data);
} else {
return view($view, $data);
}
}
}
然后不执行view('questions.index, $data);
,而是执行$this->render('questions.index', $data);
