async-http-php
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., (*1)
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:, (*2)
$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:, (*3)
$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();
