HTTPSQS (HTTP Simple Queue Service) is a Simple Queue Service Based on http get/POST requests.

Install and use the PHP queue service HTTPSQS

The Queue is also known as the First In First Out table (First In First Out), that is, the elements that First enter the Queue are extracted from the Queue. One end of the element is called the "head of the team", and the other end of the element is called the "end of the team ". Message Queue can be used to process data transmission and storage asynchronously. When you insert data frequently into the database and submit data frequently to the search engine, Message Queue can be used for asynchronous insertion. In addition, you can also put slow processing logic and limited number of concurrent processing logic in the background through message queues for processing, such as FLV video conversion, sending SMS messages, and sending email, that is, asynchronous requests are implemented.

HTTPSQS has the following features:

● Very simple, based on the http get/POST protocol. PHP, Java, Perl, Shell, Python, Ruby, and other programming languages that support HTTP protocol can be called.
● Very fast. The speed of inbound and outbound queues exceeds 10000 times/second.
● High concurrency, supporting tens of thousands of concurrent connections, C10K is not a problem.
● Supports multiple queues.
● A single queue supports up to 1 billion queues.
● Low memory consumption, massive data storage, and storage of dozens of GB of data requires less than MB of physical memory buffer.
● You can easily modify the maximum number of queues for a single queue without stopping the service.
● You can view the status of a queue in real time (including the inbound queue location, outbound queue location, number of unread queues, and maximum number of queues ).
● You can view the content of the specified queue ID (queue point), including the content of the queue that has not been output or has been output.
● Multi-character set encoding is supported when you view queue content.
● The Source Code cannot exceed 800 lines, which is suitable for secondary development.

HTTPSQS usage example:

// Generate a statement
Public function create_dzd ()
{
$ Sl_id = I ('get. sl_id ', '', 'intval ');
$ Sl_uid = I ('get. sl_uid ', '', 'intval ');

$ This-> send_task-> startTrans (); // start the transaction

$ Data ['st _ params '] = $ sl_id;
$ Data ['st _ seller_id '] = $ sl_uid;
$ Data ['st _ type'] = 3;
$ Data ['st _ add_time '] = time ();
$ Data ['st _ success '] = 1; // 1 generate a statement in the background
$ Data ['st _ is_compelete'] = 0;
$ Data ['st _ ip'] = get_client_ip (1 );
$ Id = $ this-> send_task-> add ($ data );
If ($ id ){
$ Httpsqs = $ this-> getHttpsqs ();
$ Name = self: EXPORT_RECORD;
$ Rs = $ httpsqs-> put ($ name, $ id );
If ($ rs ){
$ This-> send_task-> commit ();
$ This-> ajaxReturn (array ('code' => 0, 'msg '=>' generation started! '));
} Else {
$ This-> send_task-> rollback ();
$ This-> ajaxReturn (array ('code' => 2, 'msg '=> 'Statement generation failed '));
}
} Else {
$ This-> ajaxReturn (array ('code' => 3, 'msg '=> 'Statement generation failed '));
}
}

This is a queue application that generates statement, enters the queue, and writes records to a table record. Another java script reads the queue for processing and updating records.

HTTPSQS is encapsulated in a class and called as follows:

// Initialize the queue service
Private function getHttpsqs ()
{
Import ("COM. Httpsqs ");
$ Httpsqs = new Httpsqs ("192.168.1.8", 1218, "dafadsfasfsadfsa", 'utf-8 ');
Return $ httpsqs;
}
However, to use HTTPSQS, a queue server must be installed with the queue service.

The above initialization queue also specifies an ip address and port to connect to the Queue Server to perform queue operations.
