Future of HTTP in CakePHP
- 1. The Future of HTTP In CakePHP
- 3. Request & Response Added in 2.0.0
- 8. HTTP in PHP is :(
- 9. $_POST Only works for POST methods and url-encoded data.
- 11. Request URI Hard to find.
- 12. File Uploads A pretty big mess.
- 14. Not Invented Here Every framework has their own HTTP stack
- 15. No Shared Solutions Sharing is caring
- 16. What do other languages do?
- 17. Python Web Server Gateway Interface
- 18. Ruby Rack
- 19. Go-Lang http module in stdlib
- 20. Common Traits All these platforms have a single implementation.
- 21. PSR-7
- 23. Requests
- 24. Immutable All PSR7 objects are immutable*
- 25. // Read a header as text $value = $request->getHeaderLine(‘Content-Type’); // Read header as an array $value = $request->getHeader(‘Content-Type’); // Read all the headers $headers = $request->getHeaders(); Reading Headers
- 26. // Get an array of cookie values. $cookies = $request->getCookieParams(); // Get a list of UploadedFile objects $files = $request->getUploadedFiles(); // Read the file data. $files[0]->getStream(); $files[0]->getSize(); $files[0]->getClientFileName(); // Move the file. $files[0]->moveTo($targetPath); Cookies & Files
- 27. // Get the URI $uri = $request->getUri(); // Read data out of the URI. $path = $uri->getPath(); $query = $uri->getQuery(); $host = $uri->getHost(); URL data
- 28. // Get the application base dir $base = $request->getAttribute(‘base’); // Get the application webroot $webroot = $request->getAttribute(‘webroot’); // Get the routing parameters $params = $request->getAttribute(‘params’); Request Attributes
- 29. Responses
- 30. Also Immutable
- 31. // Bodies are also Streams. $body = new Stream(‘php://memory'); $body->write(‘{“ok”:true}’); // Build up a response. $res->withHeader(‘Content-Type’, ‘application/json’) ->withStatus(204) ->withBody($body); Building Responses
- 32. Middleware
- 36. 1. Must accept a Request, Response and ‘next’ 2. Must return a Response, or call ‘next’ 3. No more Rules. Middleware Rules
- 38. $middleware = new CakeHttpMiddlewareStack(); // Catch any exceptions in the lower layers. $middleware->push(new ErrorHandlerMiddleware()); // Handle plugin/theme assets $middleware->push(new AssetMiddleware()); // Apply routing $middleware->push(new RoutingMiddleware()); // Apply CORS at the first middleware $middleware->prepend(new CorsMiddleware()); Setup Middleware
- 39. // Using closures $wow = function ($req, $res, $next) { $res = $res->withHeader(‘X-Wow’, ‘Wow’); return $next($req, $res); }; // Add to a middleware stack $middleware->push($wow); Middleware
- 40. class WowMiddleware { public function __invoke($res, $req, $next) { $res = $res->withHeader(‘X-Wow’, ‘Wow’); return $next($req, $res); } } // Add to a middleware stack $middleware->push(new WowMiddleware()); Middleware
- 41. HttpClient
- 42. $client = new CakeHttpClient(); $res = $client->get(‘http://cakephp.org'); // Use PSR7 methods. $status = $res->getStatusCode(); $contentType = $res->getHeaderLine(‘Content-Type’); $body = $res->getBody()->getContents(); Client Example
- 43. Fully backwards compatible Client Responses still support the current interface.
- 45. Sounds Nice, but is upgrading going to suck?
- 46. Nope It should be painless really.
- 47. Timeline Now 3.3 - Fall 2016 3.4 - Early 2017 4.0 - ?
- 48. PSR-7 in 3.3.0 Opt-in stack that replaces DispatcherFilters
- 49. require dirname(__DIR__) . '/vendor/autoload.php'; use CakeHttpServer; use AppApplication; // Bind your application to the server. $app = new Application(dirname(__DIR__) . ‘/config'); $server = new Server($app); // Run the request/response and emit the response $server->emit($server->run()); index.php of the future
- 50. class Application extends BaseApplication { public function middleware($middleware) { // Catch any exceptions in the lower layers. $middleware->push(new ErrorHandlerMiddleware()); // Handle plugin/theme assets $middleware->push(new AssetMiddleware()); // Apply routing $middleware->push(new RoutingMiddleware()); return $middleware; } } Application Class
- 51. 3.4.0 NetworkRequest will implement PSR7
- 52. Future 3.x.0 Runtime errors on deprecated methods.
- 53. 4.0.0 Clean up. Remove deprecations.
- 54. In Review 1. PSR7 middleware is coming as an opt-in feature for 3.3.0 2. New applications will default to the new HTTP stack in 3.3.0 3. Controllers will have access to PSR7 methods in 3.4.0 4. Runtime deprecations will be introduced in a future 3.x 5. The code you write today will continue to work until 4.0.0.
