谷歌Apps脚本自动复制的Excel转换到谷歌片之间表

Question

我是新来的编码游戏，学习如何通过一天一天的代码。最近我迷上到谷歌应用程序脚本，学习做一个简单的数据库。我试图解码和重码的剧本，但我无法得到它的工作。这本该是excel的从原来的excel文件转换和替代现有的谷歌，而不是纸的剧本只是转换和复制成片的许多版本（1,2,3）。

// Convert the user's stored excel files to google spreadsheets based on the specified directories.
// There are quota limits on the maximum conversions per day: consumer @gmail = 250.
function convertCollection1() 
{
  var user = Session.getActiveUser(); // Used for ownership testing.
  var origin = DriveApp.getFolderById("1dPsDfoqMQLCokZK4RN0C0VRzaRATr9AN");
  var dest = DriveApp.getFolderById("1M6lDfc_xEkR4w61pUOG4P5AXmSGF1hGy");

  // Index the filenames of owned Google Sheets files as object keys (which are hashed).
  // This avoids needing to search and do multiple string comparisons.
  // It takes around 100-200 ms per iteration to advance the iterator, check if the file
  // should be cached, and insert the key-value pair. Depending on the magnitude of
  // the task, this may need to be done separately, and loaded from a storage device instead.
  // Note that there are quota limits on queries per second - 1000 per 100 sec:
  // If the sequence is too large and the loop too fast, Utilities.sleep() usage will be needed.
  var gsi = dest.getFilesByType(MimeType.GOOGLE_SHEETS), gsNames = {};
  while (gsi.hasNext())
  {
    var file = gsi.next();
    if(file.getOwner().getEmail() == user.getEmail())
      gsNames[file.getName()] = true;
  }

  // Find and convert any unconverted .xls, .xlsx files in the given directories.
  var exceltypes = [MimeType.MICROSOFT_EXCEL, MimeType.MICROSOFT_EXCEL_LEGACY];
  for(var mt = 0; mt < exceltypes.length; ++mt)
  {
    var efi = origin.getFilesByType(exceltypes[mt]);
    while (efi.hasNext())
    {
      var file = efi.next();
      // Perform conversions only for owned files that don't have owned gs equivalents.
      // If an excel file does not have gs file with the same name, gsNames[ ... ] will be undefined, and !undefined -> true
      // If an excel file does have a gs file with the same name, gsNames[ ... ] will be true, and !true -> false
      if(file.getOwner().getEmail() == user.getEmail() && !gsNames[file.getName()]
      {
        Drive.Files.insert (
          {title: file.getName(), parents: [{"id": dest.getId()}]},
          file.getBlob(),
          {convert: true}
        );
        // Do not convert any more spreadsheets with this same name.
        gsNames[file.getName()] = true;
      }
    }
  }
}

脚本的逻辑是即期。不过，也有在功能.getName()和Drive.Files.insertyou使用才造成了代码的意外行为微妙的滋扰。

folder.getName()获取文件，其中包括的.xls /扩展的.xlsx的全名。但是，当您转换与Drive.Files.insert这些文件的扩展名被删除。所以，你的gsNames对象有没有扩展，但是当代码试图访问使用!gsNames[file.getName()]它具有文件扩展名的特定元素的文件名。它总是返回undefined，这为真。

因此，你将需要删除的文件扩展名试图检查相同的文件已经转换了。删除文件扩展名正则表达式是无耻地从here复制。你的逻辑将被修改，如下所示：

if(file.getOwner().getEmail() == user.getEmail() && !gsNames[file.getName().replace(/\.[^/.]+$/, "")])

您的文件中的代码将是：

function convertCollection1() 
{
  var user = Session.getActiveUser(); // Used for ownership testing.1aJcbdGhwliTs_CZ-3ZUvQmGRDzBM7fv9
  var origin = DriveApp.getFolderById("1dPsDfoqMQLCokZK4RN0C0VRzaRATr9AN");
  var dest = DriveApp.getFolderById("1M6lDfc_xEkR4w61pUOG4P5AXmSGF1hGy");

  // Index the filenames of owned Google Sheets files as object keys (which are hashed).
  // This avoids needing to search and do multiple string comparisons.
  // It takes around 100-200 ms per iteration to advance the iterator, check if the file
  // should be cached, and insert the key-value pair. Depending on the magnitude of
  // the task, this may need to be done separately, and loaded from a storage device instead.
  // Note that there are quota limits on queries per second - 1000 per 100 sec:
  // If the sequence is too large and the loop too fast, Utilities.sleep() usage will be needed.
  var gsi = dest.getFilesByType(MimeType.GOOGLE_SHEETS), gsNames = {};
  while (gsi.hasNext())
  {
    var file = gsi.next();
    if(file.getOwner().getEmail() == user.getEmail())
      gsNames[file.getName()] = true;

    Logger.log(JSON.stringify(gsNames))
  }

  // Find and convert any unconverted .xls, .xlsx files in the given directories.
  var exceltypes = [MimeType.MICROSOFT_EXCEL, MimeType.MICROSOFT_EXCEL_LEGACY];
  for(var mt = 0; mt < exceltypes.length; ++mt)
  {
    var efi = origin.getFilesByType(exceltypes[mt]);
    while (efi.hasNext())
    {
      var file = efi.next();
      // Perform conversions only for owned files that don't have owned gs equivalents.
      // If an excel file does not have gs file with the same name, gsNames[ ... ] will be undefined, and !undefined -> true
      // If an excel file does have a gs file with the same name, gsNames[ ... ] will be true, and !true -> false
      if(file.getOwner().getEmail() == user.getEmail() && !gsNames[file.getName().replace(/\.[^/.]+$/, "")])
      {
        Drive.Files.insert (
          {title: file.getName(), parents: [{"id": dest.getId()}]},
          file.getBlob(),
          {convert: true}
        );
        // Do not convert any more spreadsheets with this same name.
        gsNames[file.getName()] = true;
      }
    }
  }
  Logger.log(JSON.stringify(gsNames))
}

注意使用Logger.log()的，用这个在未来以确定哪些程序可能正在访问VS你觉得它在做什么。

干杯!
