无法解压缩 Zip，然后使用 Google Apps 脚本解析 CSV

Question

尝试创建一个 Google Apps 脚本来读取来自特定电子邮件地址的电子邮件并将 CSV 文件的内容复制到 Google 工作表中。

问题是有时文件以 zip 附件的形式出现。我正在尝试在脚本中加入逻辑以解压缩 zip（如果它是 zip 附件），然后将数据发布到 Google 工作表。

当前收到以下错误消息：Cannot find function getDataAsString in object Blob。

任何关于让它与潜在的 zip 文件一起工作的想法/建议都会很棒。

你可以在下面找到我的完整代码：

function myFunction() {
    var threads = GmailApp.search("from:testemail@example.com");
    var message = threads[0].getMessages()[0];
    var attachment = message.getAttachments()[0];
    Logger.log(attachment.getContentType());
    // Is the attachment a CSV file
    if (attachment.getContentType() === "text/csv") {
        var sheet = SpreadsheetApp.getActiveSheet();
        var csvData = Utilities.parseCsv(attachment.getDataAsString(), ",");
      Logger.log("Found a CSV file");
        // Remember to clear the content of the sheet before importing new data
        sheet.clearContents().clearFormats();
        sheet.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);
    }
    if (attachment.getContentType() === "application/zip") {
        var sheet = SpreadsheetApp.getActiveSheet();
        var files = Utilities.unzip(attachment);
      Logger.log(files);
        var newDriveFile = DriveApp.createFile(files[0]);
        var csvData = Utilities.parseCsv(files.getDataAsString(), ",");
        Logger.log("Found a ZIP file");
        // Remember to clear the content of the sheet before importing new data
        sheet.clearContents().clearFormats();
        sheet.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);
    }
}

Utilities.unzip 将返回 blob 数组。因此，您需要在 blob 数组中引用特定的 blob。只需修改下面的代码sn-p即可。

var files = Utilities.unzip(attachment)[0];

此外，提及字符集是安全的，以便正确显示特殊字符。

var csvData = Utilities.parseCsv(attachment.getDataAsString('ISO-8859-1'), ",");

整个功能：

function exportData() {
    var threads = GmailApp.search("from:testemail@example.com");
    var message = threads[0].getMessages()[0];
    var attachment = message.getAttachments()[0];
    Logger.log(attachment.getContentType());
    // Is the attachment a CSV file
    if (attachment.getContentType() === "text/csv") {
        var sheet = SpreadsheetApp.getActiveSheet();
        var csvData = Utilities.parseCsv(attachment.getDataAsString('ISO-8859-1'), ",");
      Logger.log("Found a CSV file");
        // Remember to clear the content of the sheet before importing new data
        sheet.clearContents().clearFormats();
        sheet.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);
    }
    if (attachment.getContentType() === "application/zip") {
        var sheet = SpreadsheetApp.getActiveSheet();
        var files = Utilities.unzip(attachment)[0];
        var csvData = Utilities.parseCsv(files.getDataAsString('ISO-8859-1'), ",");
        Logger.log("Found a ZIP file");
        // Remember to clear the content of the sheet before importing new data
        sheet.clearContents().clearFormats();
        sheet.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);
    }
}
