修身PHP和服務器發送的事件（SSE）

Question

背景見here：

搭配修身我怎麼發送到同一請求多個響應，而無需退出應用程序？

Answer 1

我使用超薄API版本2和我添加的服務器發送的事件，以我現有的API是這樣的：

在index.php文件：

$app = new \Slim\Slim(); 

// other code 
.... 

// this is the route I want to use for the event stream 
$app->get('/psoback/eventstream', 
      function() use ($app) 
      { 
       require_once('event.php'); 
       $app->eventstream = new ServerSentEventHandler(); 
      } 
     ); 

// here goes the rest of my api definitions 
... 

$app->run(); 

if(isset($app->eventstream)) 
{ 
    $app->eventstream->Run(); 
} 

event.php看起來是這樣的： （例如從https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events）

<?php 
class ServerSentEventHandler 
{ 
    function __construct() 
    { 

    } 

    function Run() 
    { 
     header('Content-Type: text/event-stream'); 
     header('Cache-Control: no-cache'); 
     $counter = rand(1, 10); 
     while (1) 
     { 
      // Every second, sent a "ping" event. 

      echo "event: ping\n"; 
      $curDate = date(DATE_ISO8601); 
      echo 'data: {"time": "' . $curDate . '"}'; 
      echo "\n\n"; 

      // Send a simple message at random intervals. 

      $counter--; 

      if (!$counter) 
      { 
      echo 'data: This is a message at time ' . $curDate . "\n\n"; 
      $counter = rand(1, 10); 
      } 

      ob_end_flush(); 
      flush(); 
      sleep(1); 
     } 
    } 
}; 
?>
