超薄 4 放置和删除表单提交

Question

如何在 Slim 4 中执行 PUT 和删除表单提交？我有以下路线：$group->get('/sites/create', SitesController::class . ':create')->setName('sites_create');$group->get('/sites/{id}/edit', SitesController::class . ':edit')->setName('sites_edit');$group->post('/sites', SitesController::class . ':createSubmit')->setName('sites_create_submit');$group->put('/sites', SitesController::class . ':editSubmit')->setName('sites_edit_submit');这是我的：<form action="/sites" method="POST">    <label for="name">Site name</label>    <input type="text" class="form-control" id="name" name="name">                     <input type="hidden" name="_METHOD" value="PUT">    <button type="submit">Submit</button></form>这就是我在Slim 3中会如何做到的。但它不会转到编辑提交方法，而是转到创建提交方法。如何使用这些方法提交？

根据 Slim 4 文档，您仍然可以使用请求正文中的参数或使用标头来覆盖表单方法。_METHODPOSTX-Http-Method-Override

重要的一点（来自文档）是你需要添加到你的应用才能覆盖表单方法。Slim\Middleware\MethodOverrideMiddleware

下面是一个完全有效的示例：

<?php

require __DIR__ . '/../vendor/autoload.php';

use Slim\Factory\AppFactory;

$app = AppFactory::create();

$app->addRoutingMiddleware();

$app->add(new Slim\Middleware\MethodOverrideMiddleware);

$app->get('/', function($request, $response){

    $form =<<<form

    <form action="/put" method="post">

        <input type="hidden" name="_METHOD" value="PUT"/>

        <button type="submit">Send PUT request</button>

    </form>

    <form action="/delete" method="post">

        <input type="hidden" name="_METHOD" value="DELETE"/>

        <button type="submit">Send DELETE request</button>

    </form>

form;

    $response->getBody()->write($form);

    return $response;

});

$app->put('/put', function($request, $response){

  $response->getBody()->write('The request method is: ' . $request->getMethod());

  return $response;

});

$app->delete('/delete', function($request, $response){

    $response->getBody()->write('The request method is: ' . $request->getMethod());

    return $response;

});

$app->run();
