如何在php Slim框架中添加参数？

Question

我使用Slim框架作为调用API的背景。

我已经配置了composer.json文件：

{
  "require": {
     "slim/slim": "^2.6",
     "slim/middleware": "*"
  },
  "autoload": {
      "psr-4": {"App\\Controller\\": "server/controllers/"}
  }
}

和index.php文件：

<?php
 require 'vendor/autoload.php';
 $configs = array(  'mode'=>'development',
                'debug'=>true, 
                'log.enabled' => true,
                'templates.path' => './templates',
                'cookies.secret_key' => 'secret'
            );
$app = new \Slim\Slim($configs);

$app->get('/login', function() use ($app) {
    $app->render('login.php');
});

$app->post('/login', function() use ($app) {
   $process= new App\Controller\MiddleProcess();
   // process request to call API 
   $process->transferRequest();
});

$app->run();
?>

我在目录server/controllers/有一个文件MiddleProcess.php ：

<?php
namespace App\Controller;
class MiddleProcess {
 public $url = 'http://api.com/';
 function transferRequest() {
     $app = \Slim\Slim::getInstance();
     $post_datas = $app->request->post();
     $token = $app->getCookie('token');
     $url = $this->url.'/login';
     // How can I add param: `$token` and change 'url', then continue to call API here
     // example: http://api.com/login?access_token=$token

 }
} 
 ?>

如何更改url请求并添加参数access_token 。 然后继续调用API？

Answer 1

使用苗条的redirect方法。

//first merge any existing get params with our token param and build the query string.
$query_string = http_build_query(array_merge($app->request->get(),['access_token'=>$token]));
//call app redirect
$app->redirect($url.'?'.$query_string));
