README
An Async HTTP client based on curl_mulit* which is really simple and fast.
This project is a teaching experiment and I don't suggest to use it in a production environment, even though it is stable.
You can try to use guzzle.
Description
- If you want to use ssl or something else when you request a website, you can just realize a task class and extends the AbstractTask class.
- You can register a handler using Task object, when the response is usable the Async class will call the handler to handle the response.
- It will also return the response if it is handled by the handler or not.
- The longer the requests execute, the more time it will save.
example code:
$async = new \Jenner\Http\Async(); $task = \Jenner\Http\Task::createGet("http://www.baidu.com"); $async->attach($task, "baidu"); $task2 = \Jenner\Http\Task::createGet("http://www.sina.com"); $async->attach($task2, "sina"); $task3 = \Jenner\Http\Task::createGet("http://www.qq.com"); $async->attach($task3, "qq"); /** * you can do something here before receive the http responses * eg. query data from mysql or redis. */ $async-start(); while(true){ // nonblock if(!$async->isDone()){ echo "I am running" . PHP_EOL; sleep(1); continue; } $result = $async->execute(); print_r($result); break; } /** * or you just call execute. it will block the process until all tasks are done. * $result = $async->execute(); * print_r($result); */
use promise:
$async = new \Jenner\Http\Async(); $task = \Jenner\Http\Task::createGet("http://www.baidu.com"); $promise = $async->attach($task, "baidu"); $promise->then( function ($data) { echo 'success:' . var_export($data, true) . PHP_EOL; }, function ($data) { echo 'error:' . var_export($data, true) . PHP_EOL; } ); $async->execute();
