超过最大执行时间

Question

这是我的代码：

1. 复制电子表格并将其转储到 gdrive 文件夹（复制数量取决于我的配置文件中的员工数量）。 截至目前，我有 800 多名员工。
2. 复制后，gdrive 文件夹中的每个电子表格都会发布到 html。 （我在这里使用了一个循环）
3. 获取每个电子表格的 pubHTML 链接并将其放入我的配置文件中。

当我在第 3 步部分获取 pubHTML 并将其放入我的配置文件时，我得到了超出的最大执行时间。

我的代码按预期工作。 我想避免执行错误的最大限制。

  function replicateCards() {
  var ss = SpreadsheetApp.openById('configfile--xxxx');
  var copyCard = SpreadsheetApp.openById('replicateCard-xxxx');
  var getID = DriveApp.getFileById(copyCard.getId())
  var card = copyCard.getSheetByName("Card");
  var mastersheet = ss.getSheetByName("Mastersheet");
  var getLastRow = mastersheet.getLastRow();
  var destinationFolder = DriveApp.getFolderById('gdrivefolder-xxxx');
  var changeColorToGrayList = card.getRangeList(['C7', 'E7', 'G7', 'I7', 'K7', 'M7', 'O7', 'Q7',
                                                 'C9', 'E9', 'G9', 'I9', 'K9', 'M9', 'O9', 'Q9',

  var setValueToZero = card.getRangeList(['C8', 'E8', 'G8', 'I8', 'K8', 'M8', 'O8', 'Q8',

      SpreadsheetApp.flush();
    } catch (err) {
      Logger.log(err);
    }
  }
}

只运行一次代码，不会出现超出最大执行时间的错误。 有什么建议么？

下面的代码是根据我以前使用的代码修改的。 像这样的方法允许您完全执行一个单独无法在执行时间限制内完成的批处理。 通过了解批处理中的单个操作需要多长时间，您可以在达到该限制之前将进度保存在属性中，并以编程方式创建触发器以恢复处理。

您需要做一些事情才能使其工作：

1. 您需要修改我的getEmployees_() function 以准确地从您的配置文件中获取员工。
2. 正如我在评论中提到的，您需要重构代码，以便可以为单个员工执行复制。 该代码应在我的replicateForEmployee_() function 中为 go。
3. 运行determineTimes() function 以查看获取员工和文件复制需要多长时间。
4. 在replicate() function 中插入determineTimes()的结果。

determineTimes()的 output 将在“执行”页面（查看 > 执行）中可见。 展开执行行，您将看到如图所示的持续时间。

/**
 * Get all of the employees in the sheet. Assumes row in the sheet is one employee. Adjust the range as needed.

function getEmployees_() {
  var source = SpreadsheetApp.openById("configfile--xxxx");

}
