php-nsq,php-nsq: php-nsq php-nsq 是nsq的php客户端，采用c扩展编写，性能和稳定性

php-nsq

NSQ client for php7 . QQ Group : 616063018

intall :

Dependencies: libevent (apt-get install libevent-dev ,yum install libevent-devel)

pecl install nsq

or:

1. sudo phpize

2. ./configure

3. make

4. make install

add in your php.ini:

extension = nsq.so;

Tips:

if has the error "configure: error: Cannot find libevent headers" you should run :

./configure --with-php-config=/usr/local/php-7.2.12/bin/php-config --with-libevent-path=/usr/local/libevent-2.1.8-stable/

Example for pub:

// Normal publish

$nsqdAddr = array(

"127.0.0.1:4150",

"127.0.0.1:4154"

);

$nsq = new Nsq();

$isTrue = $nsq->connectNsqd($nsqdAddr);

for($i = 0; $i < 10000; $i++){

$nsq->publish("test", "nihao");

}

$nsq->closeNsqdConnection();

// Deferred publish

//function : deferredPublish(string topic,string message, int millisecond);

//millisecond default : [0 < millisecond < 3600000]

$deferred = new Nsq();

$isTrue = $deferred->connectNsqd($nsqdAddr);

for($i = 0; $i < 20; $i++){

$deferred->deferredPublish("test", "message daly", 3000);

}

$deferred->closeNsqdConnection();

Example for sub:

//sub

$nsq_lookupd = new NsqLookupd("127.0.0.1:4161"); //the nsqlookupd http addr

$nsq = new Nsq();

$config = array(

"topic" => "test",

"channel" => "struggle",

"rdy" => 2, //optional , default 1

"connect_num" => 1, //optional , default 1

"retry_delay_time" => 5000, //optional, default 0 , if run callback failed, after 5000 msec, message will be retried

"auto_finish" => true, //default true

);

$nsq->subscribe($nsq_lookupd, $config, function($msg,$bev){

echo $msg->payload."\n";

echo $msg->attempts."\n";

echo $msg->messageId."\n";

echo $msg->timestamp."\n";

});

Nsq Object

connectNsqd($nsqdAddrArr)

publish use, You can also use it for health check;

closeNsqdConnection()

close connecNsqd's socket

publish($topic,$msg)

deferredPublish($topic,$msg,$msec)

subscribe($nsq_lookupd,$config,$callback)

conn_timeout = 100

connection timeout for connectNsqd() in milliseconds

Message Object

The following properties and methods are available on Message objects produced by a Reader

instance.

timestamp

Numeric timestamp for the Message provided by nsqd.

attempts

The number of attempts that have been made to process this message.

messageId

The opaque string id for the Message provided by nsqd.

payload

The message payload as a Buffer object.

finish($bev,$msg->messageId)

Finish the message as successful.

touch($bev,$msg->messageId)

Tell nsqd that you want extra time to process the message. It extends the

soft timeout by the normal timeout amount.

Tips :

If you need some variable in callback ,you should use 'use' :

$nsq->subscribe($nsq_lookupd, $config, function($msg,$bev) use ($you_variable){

echo $msg->payload;

});

Requeue/Retry -- if you whant to retry your message when callback have something wrong, just throw any Exception , example:

$nsq->subscribe($nsq_lookupd, $config, function($msg){

try{

echo $msg->payload . " " . "attempts:".$msg->attempts."\n";

//do something

}catch(Exception $e){

if($msg->attempts < 3){

//the message will be retried after you configure retry_delay_time

throw new Exception("");

}else{

echo $e->getMessage();

return;

}

}

});

If you want to increase your message timeout and heartbeats time ,Two steps are needed:

#1 when nsqd startup you should set command line option:

nsqd --lookupd-tcp-address=127.0.0.1:4160 --max-heartbeat-interval=1m30s --msg-timeout=10m30s

#2 And , you should use identify config. For details, see the identify example file.

If your have strong consuming ability ,you can add you rdy num and connect num

If your execution time is more than 1 minute, you should use 'touch()' function

Do not support calling publish or deferredPublish in subscribe function, please use nsqd's HTTP interface.
