# Method Overriding Middleware 方法重寫的中間件 The Method Overidding Middleware enables you to use the`X-Http-Method-Override`request header or the request body parameter`_METHOD`to override an incoming request’s method. The middleware should be placed after the routing middleware has been added. > 覆蓋中間件的方法允許您使用`X-Http-Method-Override`請求頭或請求體參數`_METHOD`來覆蓋傳入請求的方法。 > > 應該在添加路由中間件之后放置中間件。 ## Usage ~~~php <?php use Slim\Factory\AppFactory; use Slim\Middleware\MethodOverrideMiddleware; require __DIR__ . '/../vendor/autoload.php'; $app = AppFactory::create(); //在添加MethodOverrideMiddleware之前添加路由中間件，以便在完成路由之前覆蓋該方法 // Add RoutingMiddleware before we add the MethodOverrideMiddleware so the method is overrode before routing is done $app->addRoutingMiddleware(); //添加MethodOverride中間件 // Add MethodOverride middleware $methodOverrideMiddleware = new MethodOverrideMiddleware(); $app->add($methodOverrideMiddleware); // ... $app->run(); ~~~
