发送带有图像的Google文档作为HTML格式的邮件正文不再起作用

而且，我和你也有过同样的情况.在本例中，我使用了一种变通方法.此解决方法的流程如下所示.

1. 从导出的HTML数据中检索Base64数据.
2. 将每个Base64数据创建为图像文件.
3. 从图像文件中检索超链接.
4. 用检索到的超链接替换HTML数据中的Base64数据.

当这个流反映在您的脚本中时，它将如下所示.

示例脚本1:

在此示例中，图像文件是公开共享的，并使用这些图像的webContent Links.

在测试此脚本之前，请设置为tempFolderId.

function sendGoogleDocAsHTML1() {
  var docId = "GOOGLE_DOCS_ID";
  var destinatario = "xxxxxx@gmail.com";
  var oggetto = "SUBJECT";

  var url = "https://docs.google.com/document/d/" + docId + "/export?format=html";
  var param = {
    method: "get",
    headers: { "Authorization": "Bearer " + ScriptApp.getOAuthToken() },
    muteHttpExceptions: true,
  };

  // --- I modified the below script.
  var tempFolderId = "###"; // Please set the folder ID of the folder for putting the images.
  var folder = DriveApp.getFolderById(tempFolderId);
  var html = UrlFetchApp.fetch(url, param).getContentText();
  [...html.matchAll(/src\="(data:image.*?)"/g)].forEach(([, e], i) => {
    var [mimeType, data] = e.split(",");
    var temp = folder.createFile(Utilities.newBlob(Utilities.base64Decode(data), mimeType, `image${i + 1}`));
    temp.setSharing(DriveApp.Access.ANYONE_WITH_LINK, DriveApp.Permission.VIEW);
    var url = `https://drive.google.com/uc?export=download&id=${temp.getId()}`;
    html = html.replace(e, url);
  });
  // ---

  var raw = Utilities.base64EncodeWebSafe("Subject: " + oggetto + "\r\n" +
    "To: " + destinatario + "\r\n" +
    "Content-Type: text/html; charset=UTF-8\r\n\r\n" +
    html + "\r\n\r\n");
  var message = Gmail.newMessage();
  message.raw = raw;
  var sentMsg = Gmail.Users.Messages.send(message, 'me');
}

示例脚本2:

在此示例中，使用了图像的缩略图链接.

在测试此脚本之前，请设置为tempFolderId. And also, please enable Drive API at Advanced Google services. In this case, the image files are not required to be publicly shared.

function sendGoogleDocAsHTML2() {
  var docId = "GOOGLE_DOCS_ID";
  var destinatario = "xxxxxx@gmail.com";
  var oggetto = "SUBJECT";

  var url = "https://docs.google.com/document/d/" + docId + "/export?format=html";
  var param = {
    method: "get",
    headers: { "Authorization": "Bearer " + ScriptApp.getOAuthToken() },
    muteHttpExceptions: true,
  };

  // --- I modified the below script.
  var tempFolderId = "###"; // Please set the folder ID of the folder for putting the images.
  var folder = DriveApp.getFolderById(tempFolderId);
  var html = UrlFetchApp.fetch(url, param).getContentText();
  [...html.matchAll(/src\="(data:image.*?)"/g)].forEach(([, e], i) => {
    var [mimeType, data] = e.split(",");
    var temp = folder.createFile(Utilities.newBlob(Utilities.base64Decode(data), mimeType, `image${i + 1}`));
    var url = Drive.Files.get(temp.getId()).thumbnailLink.replace("=s220", "=s1000");
    html = html.replace(e, url);
  });
  // ---

  var raw = Utilities.base64EncodeWebSafe("Subject: " + oggetto + "\r\n" +
    "To: " + destinatario + "\r\n" +
    "Content-Type: text/html; charset=UTF-8\r\n\r\n" +
    html + "\r\n\r\n");
  var message = Gmail.newMessage();
  message.raw = raw;
  var sentMsg = Gmail.Users.Messages.send(message, 'me');
}

注:

• 在此解决方法中，只有图像会替换为超链接.不幸的是，该图纸不能使用.请注意这一点.
