Laravel 5 Route变量具有空间

Question

I have some code in a controller called SearchController and I redirect to a route with some variables that were defined. The city variable has the spaces removed and a dash added for when the city has two words(ex:Des Moines). That would return "des-moines". I did this because in the URL it was showing up as "des+monies". But after changing that. The route does seem to know what to do or it breaks. So how can I tell the route that the {city} can also be things like "des-moines" instead of having "des+moines". Or is there a better way of doing this.

Url I want(but breaks and gets error):

www.domain.com/des-moines-ia-provider1-50301

SearchController(cut down version):

$city =  strtolower(preg_replace('/\s+/', '-', $data[0]->City));
$state = strtolower($data[0]->State);
$provider = strtolower($data[0]->{'Provider Name'});
$zipcode = $data[0]->{'Zip Code'};  

return redirect()->route('search.provider1',[$city,$state,$zipcode])->with('data',$data);

Routes:

Route::get('{city}-{state}-provider1-{zipcode}',['uses' => 'PagesController@provider1','as' => 'search.provider1']);

Error:

NotFoundHttpException in RouteCollection.php line 161:

What you could do is replacing in your routes separator that won't be used in in city/state/zipcode.

Maybe:

Route::get('{city}/{state}/provider1/{zipcode}',['uses' => 'PagesController@provider1','as' => 'search.provider1']);

would be better? I suppose / is not used in city/state and zipcode
