问题描述
我基于 symfony2 的应用程序必须在不同的时刻和不同的频率做一些独立的工作.例如，发送简讯、编辑报告...
My application based on symfony2 has to do some standalone jobs at differents moments and differents frequencies. For exemple, sending newsletter, editing report ...
我希望能够从应用程序添加/编辑每个任务我的任务将非常接近 cron 作业，并且将包括调用特定的 url.
I want to be able to add/edit each task from the applicationMy task would be very close to cron jobs and will consist to call a specific url.
我考虑创建一个 cron 作业，每半小时或十分钟启动一个脚本.这个脚本只做一个 curl 命令女巫得到一个 docronjob 动作.这个 docronjobaction 位于 symfony 内部，负责获取所有任务并启动它必须执行的任务.
I think about creating a cron job that launch a script every half hour, or ten minutes. this script only do a curl command witch get a docronjob action. This docronjobaction is inside symfony and is responsible to get all the task and launch the one it has to.
- 有没有更简洁的方法来实现这一目标?
- 在文档中我如何启动其他操作?
- 如何将整个控制器的时间限制设置为 0?
- 是否已经存在执行此操作的捆绑包?
推荐答案
听起来您正在将任务计划存储在数据库中.没问题.为每一种不同类型的任务(例如发送时事通讯、保存报告)创建一个服务来完成任务.然后向这个服务添加一个标签(比如 twig.extension，但是你自己的)，所以你有一个类似于 TaskChain 的东西，它知道所有的任务.
It sounds you are storing your schedule of tasks in the database. No problem. For every different type of task (eg. sending newsletter, save reports) create a service, which does the task. Then add to this services a tag (like twig.extension, but your own), so you have something like a TaskChain, which knows all the tasks.
为了执行创建一个控制台命令，它从数据库，加载任务链，并执行任务.这个控制台命令可以简单地从 cronjob 中调用，而无需将其暴露给网络.事实上，您是通过 php-cli 而不是从浏览器调用此命令，标准时间限制是无限的.执行时不应涉及控制器.
For executing create a console command, which retrieves the schedule from the database, loads the TaskChain, and executes the tasks. This console command can be simply called from a cronjob without exposing it to the web. In fact your are calling this command via the php-cli and not from a browser, the standard time limit is unlimited. No controllers should be involved for executing.
这应该全部组织在一个额外的 TaskBundle 中.
This should be all organized in an extra TaskBundle.
