PHP React\ZMQ\Context 'ON' 方法不触发

Question

我正在尝试使用 php 实现 Web 套接字服务器。

我按照棘轮中的指示进行操作。但我无法将更改推送给客户。我明白问题是"ReactZMQContext"，对任何事件都没有反应。

正如我所料，这个组件应该对open、close、message和error事件做出反应。这是我的代码：

$loop   = ReactEventLoopFactory::create();
$pusher = new MyAppPusher;
// Listen for the web server to make a ZeroMQ push after an ajax request
$context = new ReactZMQContext( $loop );
$pull    = $context->getSocket( ZMQ::SOCKET_PULL );
$pull->bind( 'tcp://127.0.0.1:9021' ); // Binding to 127.0.0.1 means the only client that can connect is itself
$pull->on( 'open',    function( $msg ){ echo "open";    } );
$pull->on( 'close',   function( $msg ){ echo "close";   } );
$pull->on( 'message', function( $msg ){ echo "message"; } );
$pull->on( 'error',   function( $msg ){ echo "error";   } );
// Set up our WebSocket server for clients wanting real-time updates
$webSock = new ReactSocketServer( '0.0.0.0:8090', $loop ); // Binding to 0.0.0.0 means remotes can connect
$webServer = new RatchetServerIoServer(
new RatchetHttpHttpServer(
new RatchetWebSocketWsServer(
new RatchetWampWampServer(
$pusher
)
)
),
$webSock
);
$loop->run();

谢谢。

除非您还修改 ZeroMQ 基础架构设置的PUSH端，否则这将不起作用：

<?php
// post.php ???
// This all was here before  ;)
$entryData = array(
'category' => $_POST['category']
, 'title'    => $_POST['title']
, 'article'  => $_POST['article']
, 'when'     => time()
);
$pdo->prepare( "INSERT INTO blogs (title, article, category, published) VALUES (?, ?, ?, ?)" )
->execute( $entryData['title'], $entryData['article'], $entryData['category'], $entryData['when'] );

// This is our new stuff
$context = new ZMQContext();
$socket  = $context->getSocket( ZMQ::SOCKET_PUSH, 'my pusher' );
$socket->connect( "tcp://localhost:5555" );
//                                     ^^^^__________ MUST BECOME 9021 after your mod-s
$socket->send( json_encode( $entryData ) );

如果这不起作用，请检查根据记录的 ZeroMQ 本机 API 服务提供的所有错误状态(实际代码取决于您的本机 API 语言包装器/绑定(。

对于另一个级别的测试，可能有一组轻量级的测试来设置python中的简单环境：

import     zmq
aClk     = zmq.Stopwatch()
aContext = zmq.Context()
aTarget  = "tcp://127.0.0.1:9021" # <- ADJUST TO PULL-er side transport-class endpoint
aPushToProveZMQ_RTO = aContext.Socket( zmq.PUSH )
aPushToProveZMQ_RTO.setsockopt(        zmq.LINGER, 0 )
aPushToProveZMQ_RTO.connect(           aTarget )
aClk.start()
try:
print( "INF: infinite loop, sending messages [[[ Use Ctrl+C to break ]]]" )
while True:
aPushToProveZMQ_RTO.send( "aLoop RTT::({0:}[us])".format( aClk.stop() ) )
pass;                                                     aClk.start()
except:
pass
finally:
aPushToProveZMQ_RTO.close()
aContext.term()
print( "INF: a gracefull exit" )
