Stomp::ack -- stomp_ack — Acknowledges consumption of a message
面向对象风格 (method):
$msg
[, array $headers
] )过程化风格:
$link
, mixed $msg
[, array $headers
] )Acknowledges consumption of a message from a subscription using client acknowledgment.
link
仅对过程化样式:由 stomp_connect() 返回的 stomp 连接标识符。
msg
The message/messageId to be acknowledged.
headers
关联数组包含附加的头信息(例如: receipt)。
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
Note:
A transaction header may be specified, indicating that the message acknowledgment should be part of the named transaction.
Stomp is inherently asynchronous. Synchronous communication can be implemented adding a receipt header. This will cause methods to not return anything until the server has acknowledged receipt of the message or until read timeout was reached.
Example #1 面向对象风格
<?php
$queue = '/queue/foo' ;
$msg = 'bar' ;
try {
$stomp = new Stomp ( 'tcp://localhost:61613' );
} catch( StompException $e ) {
die( 'Connection failed: ' . $e -> getMessage ());
}
$stomp -> send ( $queue , $msg );
$stomp -> subscribe ( $queue );
$frame = $stomp -> readFrame ();
if ( $frame -> body === $msg ) {
$stomp -> ack ( $frame );
}
$stomp -> unsubscribe ( $queue );
unset( $stomp );
?>
Example #2 过程化风格
<?php
$queue = '/queue/foo' ;
$msg = 'bar' ;
$link = stomp_connect ( 'ssl://localhost:61612' );
if (! $link ) {
die( 'Connection failed: ' . stomp_connect_error ());
}
stomp_begin ( $link , 't1' );
stomp_send ( $link , $queue , $msg , array( 'transaction' => 't1' ));
stomp_commit ( $link , 't1' );
stomp_subscribe ( $link , $queue );
$frame = stomp_read_frame ( $link );
if ( $frame [ 'body' ] === $msg ) {
stomp_ack ( $link , $frame [ 'headers' ][ 'message-id' ]);
}
stomp_unsubscribe ( $link , $queue );
stomp_close ( $link );
?>
