Question

我发现此脚本运行正常，只是它不会从最近的电子邮件中提取数据，而只会从第一封电子邮件中提取数据。如果有人可以帮助我将其配置为在拉出.csv附件后删除电子邮件，那将是完美的选择。

谢谢！

function importCSVFromGmail() { 
  //gets first(latest) message with set label
  var threads = GmailApp.getUserLabelByName('South Loop Report').getThreads(0,1);     
  var message = threads[0].getMessages()[0];
  var attachment = message.getAttachments()[0];

  // Is the attachment a CSV file
  attachment.setContentTypeFromExtension();
  if (attachment.getContentType() === "text/csv") {                            
    var ss = SpreadsheetApp.getActive();
    var sh = ss.getSheetByName("Sheet1");
    //parses content of csv to array
    var dataString = attachment.getDataAsString();
    var csvData = CSVToArray(dataString);

    // Remember to clear the content of the sheet before importing new data
    sh.clearContents().clearFormats();                                         
    //pastes array to sheet
    var lastRowValue = sh.getLastRow();
    for (var i = 0; i < csvData.length; i++) {
       sh.getRange(i+lastRowValue+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
    } 
  }

  //marks the Gmail message as read and unstars it (Filter sets a star)
  message.markRead();                                                          
  message.unstar();                                                            

}

//The code formats the code so it can be entered into the Google Script

function CSVToArray( strData, strDelimiter ){ 
  // Check to see if the delimiter is defined. If not,
  // then default to comma.
  strDelimiter = (strDelimiter || ",");

  // Create a regular expression to parse the CSV values.
  var objPattern = new RegExp(
    (
      // Delimiters.
      "(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +


      // Quoted fields.
      "(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +


      // Standard fields.
      "([^\"\\" + strDelimiter + "\\r\\n]*))"
    ),
    "gi"
  );


  // Create an array to hold our data. Give the array
  // a default empty first row.
  var arrData = [[]];

  // Create an array to hold our individual pattern
  // matching groups.
  var arrMatches = null;

  // Keep looping over the regular expression matches
  // until we can no longer find a match.
  while (arrMatches = objPattern.exec( strData )){

    // Get the delimiter that was found.
    var strMatchedDelimiter = arrMatches[ 1 ];

    // Check to see if the given delimiter has a length
    // (is not the start of string) and if it matches
    // field delimiter. If id does not, then we know
    // that this delimiter is a row delimiter.
    if (
      strMatchedDelimiter.length &&
      (strMatchedDelimiter != strDelimiter)
    ){

      // Since we have reached a new row of data,
      // add an empty row to our data array.
      arrData.push( [] );

    }

    // Now that we have our delimiter out of the way,
    // let's check to see which kind of value we
    // captured (quoted or unquoted).
    if (arrMatches[ 2 ]){

      // We found a quoted value. When we capture
      // this value, unescape any double quotes.
      var strMatchedValue = arrMatches[ 2 ].replace(
        new RegExp( "\"\"", "g" ),
        "\""
      );

    } else {

      // We found a non-quoted value.
      var strMatchedValue = arrMatches[ 3 ];

    }

    // Now that we have our value string, let's add
    // it to the data array.
    arrData[ arrData.length - 1 ].push( strMatchedValue );
  }

  // Return the parsed data.
  return( arrData );
  var label = GmailApp.getUserLabelByName("South Loop Report");
  label.deleteLabel();
  // Move the first message in your inbox to trash
  var firstThread = GmailApp.getInboxThreads(0,1)[0];
  var firstMessage = firstThread.getMessages()[0];
  GmailApp.moveMessageToTrash(firstMessage);
}

同样，代码正常工作，我只需要它在处理csv文件后就删除电子邮件，因此我可以为其运行自动触发器以每5分钟从新电子邮件中提取附件。

谢谢！

您的脚本有效。对于此脚本，您想添加一个删除消息的功能。
- 您要删除函数importCSVFromGmail中最后一个消息。

如果我的理解是正确的，那么该修改如何？

修改后的脚本：

请在函数importCSVFromGmail中添加以下脚本，如下所示。使用此功能时，please enable Gmail API at Advanced Google services.

从：

  message.markRead();
  message.unstar();

}

至：

  message.markRead();
  message.unstar();
  Gmail.Users.Messages.remove("me", message.getId()); // Added

}

注意：

在此修改中，消息被完全删除。因此，在运行脚本时，请注意这一点。我建议使用示例消息进行测试。
在CSVToArray的功能中，return( arrData );不会运行return( arrData );下面的脚本。请注意这一点。
