Slim how to take the post data from a form with file upload?

如何使用slim获取post数据。我有一个像这样的函数调用

$this->app->post("/post/create", array($this, "createPost"));我想从PHP HTML表单获得的帖子数据。我接受了这样的请求

$request = 'Slim'Slim::getInstance()->request();

并获取如下的post数据

$userId = $_POST["user"];
$content = $_POST["content"];
$datetime = $_POST["date"];
$filename = $_FILES["image"]["name"];
$type = $_FILES["image"]["type"];
$size = $_FILES["image"]["size"];
$filetmpname = $_FILES["image"]["tmp_name"];

这是正确的做法吗?

如果您使用Slim你可以这样做:

$app->post('/users', function ($request, $response) {
   $formDataArry = $request->getParsedBody();
    // do something with formDataArry 
});

你可以这样做:

$this->app = new 'Slim'Slim();
$this->app->post("/post/create", function () {
    $userId = $this->app->request->post('user');
    // or
    $allPostVars = $this->app->request->post();
    $userId = $allPostVars['user'];
    //...
});

如果你不想使用匿名函数("在PHP 5.4.0之前不可能使用$this from anonymous function ")，我认为你可以这样做:

$this->app->post("/post/create", 'createPost');

function createPost() {
        $userId = $this->app->request->post('user');
        //...
}

如果你使用Slim 3:

<?php
namespace Vendor'Product'Classes;
use Psr'Http'Message'ServerRequestInterface as Request;
use Psr'Http'Message'ResponseInterface as Response;
class LoginController
{
  public function loginUser(Request $request, Response $response)
  {
        $username = $request->getParam('username');
        $password = $request->getParam('password');
        // Logic to validate login ommited.
  }
}
