我想使用Windows任务计划程序(如cron作业)定期运行CodeIgniter控制器。我使用this方法使用任务调度程序运行独立的php文件,但未能在CodeIgniter控制器上实现此功能。
这是我的控制器:
<?php
defined("BASEPATH") OR exit("No direct script access allowed");
class Cron_test extends CI_Controller {
public $file;
public $path;
public function __construct()
{
parent::__construct();
$this->load->helper("file");
$this->load->helper("directory");
$this->path = "application" . DIRECTORY_SEPARATOR . "cron_test" . DIRECTORY_SEPARATOR;
$this->file = $this->path . "cron.txt";
}
public function index()
{
$date = date("Y:m:d h:i:s");
$data = $date . " --- Cron test from CI";
$this->write_file($data);
}
public function write_file($data)
{
write_file($this->file, $data . "\n", "a");
}
}
我想定期运行index()
方法。
任何帮助都将受到高度赞赏。

将write_file()设置为私有或受保护的方法,以禁止从浏览器中使用它。在服务器上设置crontab(如果是Linux,或者是Windows服务器时间表)。使用$path
的完整路径(即$this->path = APPPATH . "cron_test" . DIRECTORY_SEPARATOR;
)。使用仔细检查以查看是否发出了cli请求。
类似的东西:
<?php
defined("BASEPATH") OR exit("No direct script access allowed");
class Cron_test extends CI_Controller
{
public $file;
public $path;
public function __construct()
{
parent::__construct();
$this->load->helper("file");
$this->load->helper("directory");
$this->path = APPPATH . "cron_test" . DIRECTORY_SEPARATOR;
$this->file = $this->path . "cron.txt";
}
public function index()
{
if ($this->is_cli_request())
{
$date = date("Y:m:d h:i:s");
$data = $date . " --- Cron test from CI";
$this->write_file($data);
}
else
{
exit;
}
}
private function write_file($data)
{
write_file($this->file, $data . "\n", "a");
}
}
然后,在您的服务器上设置crontab。这看起来像是:
* 12 * * * /var/www/html/index.php cli/Cron_test
