Laravel Responses and views

Base response

Direct response string
Route::get (' example/test20 ', function () {
Return ' Hello World ';
});
Customizing HTTP Responses
Route::get (' example/test21 ', function () {
return Response::make (' content not present ', 404);
});
Response View
Route::get (' example/test22 ', function () {
Return Response::view (' test22 ');
});
Add a cookie to a response
Route::get (' example/test23 ', function () {
Return Response::view (' test22 ')->withcookie (' Cookie::make (' key '), ' This is value ');

Response redirection

Response redirection
Route::get (' Example/test24 ', function () {
Return redirect::to (' example/test21 ')->with (' username ', ' xiaoming ');
});
REDIRECT with data
Route::get (' Example/test25 ', function () {
The With method writes the data to the session and obtains the data through the Session::get method.
Return redirect::to (' example/test21 ')->with (' username ', ' xiaoming ');
});
Redirect to named Route
return Redirect::route (' login ');
Redirect values named routes with named arguments
return Redirect::route (' profile ', array (' user ' = 1));
Redirect to the specified controller method
Return redirect::action (' Homecontroller@index ');
Redirect to the specified controller method and can take the parameter
Return redirect::action (' Usercontroller@profile ', array (' user ' = 1));

Response View

Responding to views and passing parameters
Route::get (' Example/test30 ', function () {
The first way
Return View::make (' Test30 ', Array (' name ' = ' xiaoming '));
The second way
Return View::make (' Test30 ')->with (' name ', ' xiaoming2 ');
The Third Way
Return View::make (' Test30 ')->withname (' Xiaoming3 ');
Fourth Way, note: share the same data in all views
View::share (' name ', ' Steve ');
});
Passing in a child view in a view
Route::get (' Example/test31 ', function () {
$data = Array (' name ' = ' John ');
The child view is placed in the app/views/child/child_view.php, and you can pass the variable to it
Return View::make (' Test30 ')->with ($data)->nest (' Child ', ' Child.child_view ', $data);
});

View component or view synthesizer

If you want the view to be created, you can define the view component by tying the specified data:

View::composer (' Profile ', function ($view)
{
$view->with (' Count ', User::count ());
});

To add multiple views to a view component:

View::composer (Array (' Profile ', ' dashboard '), function ($view)
{
$view->with (' Count ', User::count ());
});

If you are using class-based view components:

View::composer (' profile ', ' profilecomposer ');

The view component class is created like this:

Class Profilecomposer {
Public function Compose ($view)
{
$view->with (' Count ', User::count ());
}
}

Special response

Creating a JSON response
return Response::json (Array (' name ' = ' Steve ', ' state ' = ' CA '));
Create JSONP response
return Response::json (Array (' name ' = ' Steve ', ' state ' = ' CA ') ')->setcallback (Input::get (' callback '));
File Download response
Return Response::d ownload ($pathToFile);
Return Response::d ownload ($pathToFile, $name, $headers);
Note: The class library Symfony httpfoundation that manages file downloads requires the file name to be ASCII encoded.

Response macros, using Response::macro to customize responses

Response::macro (' Caps ', function ($value)
{
Return Response::make (Strtoupper ($value));
});

The macro method accepts two parameters, one specifying the macro name and one closure. When a macro of that name is called through the Response class, the closure is executed:

return response::caps (' foo ');

You can define macros in the files in the App/start directory. Alternatively, you can organize your macro with a separate file and include the file in a start file.
