调度触发器节点#

¥Schedule Trigger node

使用计划触发器节点按固定时间间隔和时间运行工作流。其工作方式类似于类 Unix 系统中的 Cron 软件实用程序。

¥Use the Schedule Trigger node to run workflows at fixed intervals and times. This works in a similar way to the Cron software utility in Unix-like systems.

You must activate the workflow

如果工作流使用“计划”节点作为触发器，请确保保存并激活该工作流。

¥If a workflow uses the Schedule node as a trigger, make sure that you save and activate the workflow.

Timezone settings

The node relies on the timezone setting. n8n uses either:

  1. The workflow timezone, if set. Refer to Workflow settings for more information.
  2. The n8n instance timezone, if the workflow timezone isn't set. The default is America/New York for self-hosted instances. n8n Cloud tries to detect the instance owner's timezone when they sign up, falling back to GMT as the default. Self-hosted users can change the instance setting using Environment variables. Cloud admins can change the instance timezone in the Admin dashboard.

节点参数#

¥Node parameters

添加触发规则以确定触发器何时运行。

¥Add Trigger Rules to determine when the trigger should run.

使用触发间隔选择触发的时间间隔单位。所有其他参数取决于你选择的间隔。选择以下选项：

¥Use the Trigger Interval to select the time interval unit of measure to schedule the trigger for. All other parameters depend on the interval you select. Choose from:

¥Seconds trigger interval

¥Minutes trigger interval

¥Hours trigger interval

¥Days trigger interval

¥Weeks trigger interval

¥Months trigger interval

¥Custom (Cron) interval

你可以添加多个触发规则，以便按不同的计划运行节点。

¥You can add multiple Trigger Rules to run the node on different schedules.

请参阅以下各节，了解有关配置每个触发间隔的更多详细信息。请参阅 模板和示例 以了解更多示例。

¥Refer to the sections below for more detail on configuring each Trigger Interval. Refer to Templates and examples for further examples.

秒触发间隔#

¥Seconds trigger interval

  • 触发间隔：输入每次工作流触发之间的间隔时间（秒数）。例如，如果你在此处输入 30，则触发器将每 30 秒运行一次。

¥Seconds Between Triggers: Enter the number of seconds between each workflow trigger. For example, if you enter 30 here, the trigger will run every 30 seconds.

分钟触发间隔#

¥Minutes trigger interval

  • 触发间隔分钟数：输入每次工作流触发之间的间隔时间（分钟数）。例如，如果你在此处输入 5，则触发器将每 5 分钟运行一次。

¥Minutes Between Triggers: Enter the number of minutes between each workflow trigger. For example, if you enter 5 here, the trigger will run every 5 minutes.

小时触发间隔#

¥Hours trigger interval

  • 触发间隔：输入每次工作流触发之间的小时数。

¥Hours Between Triggers: Enter the number of hours between each workflow trigger.

  • 触发分钟：输入触发节点运行时的分钟数（从 0 到 59）。

¥Trigger at Minute: Enter the minute past the hour to trigger the node when it runs, from 0 to 59.

例如，如果你输入 6“触发间隔小时数”，30“触发时间（分钟）”，则节点将每六小时运行一次，即每小时的 30 分。

¥For example, if you enter 6 Hours Between Triggers and 30 Trigger at Minute, the node will run every six hours at 30 minutes past the hour.

天触发间隔#

¥Days trigger interval

  • 触发间隔天数：输入每次工作流触发之间的天数。

¥Days Between Triggers: Enter the number of days between each workflow trigger.

  • 触发小时：选择触发节点的小时。

¥Trigger at Hour: Select the hour of the day to trigger the node.

  • 触发分钟：输入触发节点运行时的分钟数（从 0 到 59）。

¥Trigger at Minute: Enter the minute past the hour to trigger the node when it runs, from 0 to 59.

例如，如果你输入 2“触发间隔天数”，15“触发时间（分钟）”，则节点将每两天上午 9:15 运行一次。

¥For example, if you enter 2 Days Between Triggers, 9am for Trigger at Hour, and 15 Trigger at Minute, the node will run every two days at 9:15am.

触发间隔（周）#

¥Weeks trigger interval

  • 周间隔触发器：输入每个工作流触发器之间的周数。

¥Weeks Between Triggers: Enter the number of weeks between each workflow trigger.

  • 工作日触发：选择要触发节点的星期几。

¥Trigger on Weekdays: Select the day(s) of the week you want to trigger the node.

  • 触发小时：选择触发节点的小时。

¥Trigger at Hour: Select the hour of the day to trigger the node.

  • 触发分钟：输入触发节点运行时的分钟数（从 0 到 59）。

¥Trigger at Minute: Enter the minute past the hour to trigger the node when it runs, from 0 to 59.

例如，如果你输入“2 周触发间隔”、“周一触发”、“下午 3 点触发（每小时）”和“30 分钟触发”，则节点将每两周的周一下午 3:30 运行一次。

¥For example, if you enter 2 Weeks Between Triggers, Monday for Trigger on Weekdays, 3pm for Trigger at Hour, and 30 Trigger at Minute, the node will run every two weeks on Monday at 3:30 PM.

月触发间隔#

¥Months trigger interval

  • 触发间隔月数：输入每次工作流触发之间的间隔时间（月数）。

¥Months Between Triggers: Enter the number of months between each workflow trigger.

  • 每月特定日期触发：输入触发日期的日期，从 1 到 31。如果某个月份没有这一天，则该节点不会触发。例如，如果你在此处输入 30，则节点在二月份不会触发。

¥Trigger at Day of Month: Enter the day of the month the day should trigger at, from 1 to 31. If a month doesn't have this day, the node won't trigger. For example, if you enter 30 here, the node won't trigger in February.

  • 触发小时：选择触发节点的小时。

¥Trigger at Hour: Select the hour of the day to trigger the node.

  • 触发分钟：输入触发节点运行时的分钟数（从 0 到 59）。

¥Trigger at Minute: Enter the minute past the hour to trigger the node when it runs, from 0 to 59.

例如，如果你输入 3“触发间隔月数”，28“触发时间（日）”，0“触发时间（分钟）”，则节点将每季度在每月 28 日上午 9:00 运行一次。

¥For example, if you enter 3 Months Between Triggers, 28 Trigger at Day of Month, 9am for Trigger at Hour, and 0 Trigger at Minute, the node will run each quarter on the 28th day of the month at 9:00 AM.

自定义（Cron）间隔#

¥Custom (Cron) interval

输入自定义 cron 表达式以设置触发器的计划。

¥Enter a custom cron Expression to set the schedule for the trigger.

要生成 Cron 表达式，你可以使用 crontab 专家。将你使用 crontab guru 生成的 Cron 表达式粘贴到 n8n 的“表达式”字段中。

¥To generate a Cron expression, you can use crontab guru. Paste the Cron expression that you generated using crontab guru in the Expression field in n8n.

Using variables in the Cron expression

虽然可以在计划触发器中使用变量，但它们的值仅在工作流激活时才会计算。如果在工作流激活后更改设置中的变量值，这些更改不会影响 cron 计划。要重新评估变量，请将工作流设置为“非活动”，然后再将其切换回“活动”。

¥While variables can be used in the scheduled trigger, their values only get evaluated when the workflow is activated. If you alter a variable's value in the settings after a workflow is activated, the changes won't alter the cron schedule. To re-evaluate the variable, set the workflow to Inactive and then back to Active again

为什么 Cron 表达式中有六个星号#

¥Why there are six asterisks in the Cron expression

Cron 表达式中的第六个星号表示秒数。此项设置是可选的。即使你未设置秒数，此节点也会执行。

¥The sixth asterisk in the Cron expression represents seconds. Setting this is optional. The node will execute even if you don't set the value for seconds.
