WP-Cron

以下操作钩子可供使用,从 WP-Cron 内部调用:

gatographql__execute_query

此钩子接收以下参数(按此顺序):

#必填?参数说明
1$query要执行的 GraphQL Query
2$variablesGraphQL 变量
3$operationName要执行的操作名称
4$executeAsUser执行 Query 时登录的用户
5$schemaConfigurationIDOrSlug执行 Query 时应用的 Schema 配置 ID(整数)或 slug(字符串)。传入 null 将使用默认值,传入 -1 表示「不使用 Schema 配置」

当 Query 需要已登录用户时(例如执行 mutation),需要使用 $executeAsUser 参数:

  • 若已提供,具有指定 ID(整数)或用户名(字符串)的用户将在执行 GraphQL Query 前立即登录,执行完毕后立即登出。
  • 若未提供,执行 Query 时将不会有用户登录。

gatographql__execute_persisted_query

此钩子接收以下参数(按此顺序):

#必填?参数说明
1$persistedQueryIDOrSlugPersisted Query 的 ID(整数)或 slug(字符串)
2$variablesGraphQL 变量
3$operationName要执行的操作名称
4$executeAsUser执行 Query 时登录的用户

请注意,要应用的 Schema 配置已在 persisted query 内部选定。

示例

以下 WP-Cron 事件执行钩子 gatographql__execute_persisted_query,发送每日邮件,显示站点新增评论数:

  • 过去 24 小时内
  • 过去 1 年内
  • 本月初至今
  • 本年初至今

我们创建一个 slug 为 "daily-stats-by-email-number-of-comments" 的 Persisted Query,内容如下:

query CountComments {
  DATE_ISO8601: _env(name: DATE_ISO8601) @remove
 
  timeToday: _time
  dateToday: _date(format: $__DATE_ISO8601, timestamp: $__timeToday)
  
  timeYesterday: _intSubtract(subtract: 86400, from: $__timeToday)
  dateYesterday: _date(format: $__DATE_ISO8601, timestamp: $__timeYesterday)
  
  time1YearAgo: _intSubtract(subtract: 31536000, from: $__timeToday)
  date1YearAgo: _date(format: $__DATE_ISO8601, timestamp: $__time1YearAgo)
 
  timeBegOfThisMonth: _makeTime(hour: 0, minute: 0, second: 0, day: 1)
  dateBegOfThisMonth: _date(format: $__DATE_ISO8601, timestamp: $__timeBegOfThisMonth)
 
  timeBegOfThisYear: _makeTime(hour: 0, minute: 0, second: 0, month: 1, day: 1)
  dateBegOfThisYear: _date(format: $__DATE_ISO8601, timestamp: $__timeBegOfThisYear)
  
  commentsAddedInLast24Hs: commentCount(filter: { dateQuery: { after: $__dateYesterday } } )
    @export(as: "commentsAddedInLast24Hs")
  commentsAddedInLast1Year: commentCount(filter: { dateQuery: { after: $__date1YearAgo } } )
    @export(as: "commentsAddedInLast1Year")
  commentsAddedSinceBegOfThisMonth: commentCount(filter: { dateQuery: { after: $__dateBegOfThisMonth } } )
    @export(as: "commentsAddedSinceBegOfThisMonth")
  commentsAddedSinceBegOfThisYear: commentCount(filter: { dateQuery: { after: $__dateBegOfThisYear } } )
    @export(as: "commentsAddedSinceBegOfThisYear")
}
 
query CreateEmailMessage @depends(on: "CountComments") {
  emailMessageTemplate: _strConvertMarkdownToHTML(
    text: """
 
This is the number of comments added to the site:
 
| Period | # Comments added |
| --- | --- |
| **In the last 24 hs**: | {$commentsAddedInLast24Hs} |
| **In the last 365 days**: | {$commentsAddedInLast1Year} |
| **Since begginning of this month**: | {$commentsAddedSinceBegOfThisMonth} |
| **Since begginning of this year**: | {$commentsAddedSinceBegOfThisYear} |
 
    """
  )
  emailMessage: _strReplaceMultiple(
    search: [
      "{$commentsAddedInLast24Hs}",
      "{$commentsAddedInLast1Year}",
      "{$commentsAddedSinceBegOfThisMonth}",
      "{$commentsAddedSinceBegOfThisYear}"
    ],
    replaceWith: [
      $commentsAddedInLast24Hs,
      $commentsAddedInLast1Year,
      $commentsAddedSinceBegOfThisMonth,
      $commentsAddedSinceBegOfThisYear
    ],
    in: $__emailMessageTemplate
  )
    @export(as: "emailMessage")
}
 
mutation SendDailyStatsByEmailNumberOfComments(
  $to: [String!]!
)
  @depends(on: "CreateEmailMessage")
{
  _sendEmail(
    input: {
      to: $to
      subject: "Daily stats: Number of new comments"
      messageAs: {
        html: $emailMessage
      }
    }
  ) {
    status
  }
}

然后,通过 PHP 调度 WP-Cron 事件:

\wp_schedule_event(
  time(),
  'daily',
  'gatographql__execute_persisted_query',
  [
    'daily-stats-by-email-number-of-comments',
    [
      'to' => ['admin@yoursite.com']
    ],
    'SendDailyStatsByEmailNumberOfComments',
    1 // This is the admin user's ID
  ]
);

或使用 WP-Crontrol 插件:

  • 事件类型: Standard cron event
  • 钩子名称: gatographql__execute_persisted_query
  • 参数: ["daily-stats-by-email-number-of-comments",{"to":["admin@yoursite.com"]},"SendDailyStatsByEmailNumberOfComments",1]
  • 重复频率: Once Daily
