Google保存Google的附件

Question

基本上，我要做的是把收到的电子邮件中的所有附件放到google的一个文件夹中(大部分是.PDF)。但它说，我不能超过500个附加的文件与搜索功能，我必须使用一个叫做pageToken的东西，我不知道如何应用到我的代码。因此，我需要一些建议或指导，或者一些例子来做这件事。

​

function saveGmailtoGoogleDrive() {

  const folderId = '1apaQJjDSK-bNfd3ZgiFqK23cE7SCPqoB'; //Google Drive Folder

  const searchQuery = 'label:unread has:attachment'; //Filter

  const threads = GmailApp.search(searchQuery, 0, 500);

  

  threads.forEach(thread => {
    const messages = thread.getMessages();
    messages.forEach(message => {

      const attachments = message.getAttachments({
          includeInlineImages: false,
          includeAttachments: true
          
      });

      attachments.forEach(attachment => {

        // Insert the attachment to google drive folder

        Drive.Files.insert(
          {
            title: attachment.getName(),
            mimeType: attachment.getContentType(),
            parents: [{ id: folderId }]
          },
          attachment.copyBlob()
        );
      });
    });
  });
};

search(query, start, max)方法的参数是query, start, max。max的当前最大值是500。当此值结束时，会发生像Argument max cannot exceed 500.这样的错误。start是搜索的起始位置。所以我想这可以用来实现你的目标。当这反映在您的脚本中时，如下所示。

修改脚本：

发自：

const threads = GmailApp.search(searchQuery, 0, 500);

至：

let [start, end] = [0, 500];
let threads = [];
do {
  const t = GmailApp.search(searchQuery, start, end);
  start += end;
  threads = [...threads, ...t];
} while (threads.length == start);

• 通过这一修改，您可以在threads中检索超过500封电子邮件。
