Laravel - Response

In Laravel, the Response class is used to build HTTP responses that can be sent back to the client. It is part of the Illuminate HTTP package and provides a convenient way to work with HTTP responses. Here are some common operations and features related to the Response class in Laravel:

Creating Responses:

You can create responses using various methods. For example, you can use the response helper function or the Response facade:

use Illuminate\Support\Facades\Response;

// Using the response helper function
$response = response('Hello, World!');

// Using the Response facade
$response = Response::make('Hello, World!');
 

Sending JSON Responses:

You can easily send JSON responses using the json method:

return response()->json(['key' => 'value']);
 

Setting Status Code:

You can set the HTTP status code for the response:

return response('Not Found', 404);
 

Attaching Headers:

You can attach headers to the response:

return response('Hello')->header('Content-Type', 'text/plain');
 

Redirecting:

You can create redirects using the redirect method:

return redirect('new-url');
 

Attaching Cookies:

As mentioned earlier, you can attach cookies to the response:

return response('Hello')->cookie('username', 'john_doe', 30);
 

File Downloads:

You can force the user's browser to download a file:

return response()->download($pathToFile);
 

Views and HTML Responses:

You can return HTML content or views as responses:

return response()->view('welcome');
 

Response Macros:

You can extend the Response class with your own macros for custom functionality:

use Illuminate\Support\Facades\Response;

Response::macro('uppercase', function ($value) {
    return response(strtoupper($value));
});

// Usage
return response()->uppercase('hello');
 

Response Instances:

You can manipulate response instances using various methods, such as with, withErrors, and header:

return response('Hello')->with('key', 'value')->withErrors(['error' => 'Something went wrong']);
