Slim 3 - isPost() 的替代品?

Slim 3 - replacement for isPost()?

在 Slim 2 中,我会这样做,

$app->map('/login', function () use ($app) {

    // Test for Post & make a cheap security check, to get avoid from bots
    if ($app->request()->isPost() && sizeof($app->request()->post()) >= 2) {

        //
    }

    // render login
    $app->render('login.twig');

})->via('GET','POST')->setName('login');

但在 Slim 3 中,

// Post the login form.
$app->post('/login', function (Request $request, Response $response, array $args) {

    // Get all post parameters:
    $allPostPutVars = $request->getParsedBody();

    // Test for Post & make a cheap security check, to get avoid from bots
    if ($request()->isPost() && sizeof($allPostPutVars) >= 2) {

        ///
    }

});

我收到这个错误,

Fatal error: Function name must be a string in C:...

显然 isPost() 已被弃用,那么我应该在 Slim 3 中使用什么来替代 isPost?

根据documentation and ,Slim 支持这些专有方法:

  • $request->isGet()
  • $request->isPost()
  • $request->isPut()
  • $request->isDelete()
  • $request->isHead()
  • $request->isPatch()
  • $request->isOptions()

这是一个用法示例:

<?php
require 'vendor/autoload.php';

use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\ResponseInterface;

$app = new \Slim\App;
$app->map(['GET', 'POST', 'PUT', 'DELETE', 'HEAD', 'PATCH', 'OPTIONS'], '/', function (ServerRequestInterface $request, ResponseInterface $response) {
    echo "isGet():" . $request->isGet() . "<br/>";
    echo "isPost():" . $request->isPost() . "<br/>";
    echo "isPut():" . $request->isPut() . "<br/>";
    echo "isDelete():" . $request->isDelete() . "<br/>";
    echo "isHead():" . $request->isHead() . "<br/>";
    echo "isPatch():" . $request->isPatch() . "<br/>";
    echo "isOptions():" . $request->isOptions() . "<br/>";

    return $response;
});

$app->run();

在 Slim 4 中,没有这样的帮助器,因此语法变得更长(就像很多 Slim 4 的东西):

$request->getMethod() === 'POST'
