//控制器

   $postdata = file_get_contents("php://input");
   $request = json_decode($postdata,true);
   $location = $request['location'];
   if(empty($location) != true){
           $tourists = User::where('block','0')
                       ->where('location', $location)
                       ->orderBy('updated_at', 'desc')
                       ->get();                 
   }else{
           $tourists = User::where('block','0')

推荐答案

这Laravel的版本，您使用的？如果打开调试，什么是500错误给出的消息？

Which version of Laravel are you using? If you turn on debugging, what is the message given for the 500 error?

我的猜测是，你的请求变量的位置指标未设置。 Laravel提供检索请求输入，已经占指标这可能会或可能不会进行设置，所以你应该使用它。

My guess would be that the 'location' index of your request variable is not set. Laravel provides a much better way of retrieving the request input, which already accounts for indexes which may or may not be set, so you should use that.

总之，假设你在Laravel 5+，这样做在你的控制器：

Anyway, assuming you're on Laravel 5+, do this in your controller:

public function touristsData()
{
    $query = User::where('block','0');

    if (request()->has('location')) {
        $query->where('location', request('location'));
    }

    $tourists = $query->orderBy('updated_at', 'desc')->get();

    return view('frontend.data.touristsData', compact('tourists'));
}

和同样的事情，但对于Laravel 4.2：

And the same thing, but for Laravel 4.2:

public function touristsData()
{
    $query = User::where('block','0');

    if (Input::has('location')) {
        $query->where('location', Input::get('location'));
    }

    $tourists = $query->orderBy('updated_at', 'desc')->get();

    return View::make('frontend.data.touristsData', compact('tourists'));
}
