Samples

Normal task

php tests/normal_api_task.php

<?php
require_once __DIR__ . '/../vendor/autoload.php';

\Tarth\Tool\Redis::setCacheServer('127.0.0.1:6379');
\Tarth\Tool\Redis::setQueueServer('127.0.0.1:6379');

$task = \Tarth\Tool\Task::createApiTask('http://alleria.mcp.wap.grid.sina.com.cn/test/normal');
echo \Tarth\Tool\Task::exec();

Timer task

php tests/timer_task.php

<?php
require_once __DIR__ . '/../vendor/autoload.php';

$task = \Tarth\Tool\Task::createApiTask('http://alleria.mcp.wap.grid.sina.com.cn/test/normal?case=timer&time=' . time());
$task->runAfter(100);

echo \Tarth\Tool\Task::exec();

Multi task

php tests/multi_task.php

<?php
require_once __DIR__ . '/../vendor/autoload.php';

$task = \Tarth\Tool\Task::createApiTask('http://alleria.mcp.wap.grid.sina.com.cn/test/normal?case=atom&index=1&date=' . date('YmdHis'));
$task = \Tarth\Tool\Task::createApiTask('http://alleria.mcp.wap.grid.sina.com.cn/test/normal?case=atom&index=2&date=' . date('YmdHis'));
echo \Tarth\Tool\Task::exec();

Atom task

php tests/atom_task.php

<?php
require_once __DIR__ . '/../vendor/autoload.php';

$task = \Tarth\Tool\Task::createApiTask('http://alleria.mcp.wap.grid.sina.com.cn/test/normal?case=atom&index=1&date=' . date('YmdHis'));
$task = \Tarth\Tool\Task::createApiTask('http://alleria.mcp.wap.grid.sina.com.cn/test/normal?case=atom&index=2&date=' . date('YmdHis'));
$task = \Tarth\Tool\Task::atomTask();
$task->runAfter(600)->canClose();

echo \Tarth\Tool\Task::exec();
