Gmail API会通过批量请求返回400 BadRequest

我正在尝试使用以下内容向gmail发出批量http请求（在带有Meteor / HTTP的服务器上）：

batchGetMessages = (accessToken, ids) => {
  let userId = 'me';
  let url = `https://www.googleapis.com/batch`;
  let boundary = `batch_message_request`;
  let body = ``;

  _.each(ids, (id) => {
    body = `${body}
    --${boundary}
    Content-Type: application/http

    GET /gmail/v1/users/${userId}/messages/${id.id}?format=metadata&fields=id%2Cpayload
    `
  });

  body = `${body}
    --${boundary}--`

  let options = {
    headers: {
      'Authorization': `Bearer ${accessToken}`,
      'Content-Type': `multipart/mixed; boundary="${boundary}"`,
    },
    content: body,
  };

  let data = HTTP.post(url, options);
  console.log('data: ', data);
}

身体的绳子看起来像这样：

--batch_message_request
Content-Type: application/http

GET /gmail/v1/users/me/messages/15375be281102d3d?format=metadata&fields=id%2Cpayload

--batch_message_request
Content-Type: application/http

GET /gmail/v1/users/me/messages/15366f87db6bdfeb?format=metadata&fields=id%2Cpayload

--batch_message_request
Content-Type: application/http

GET /gmail/v1/users/me/messages/15365d62f152dea2?format=metadata&fields=id%2Cpayload

--batch_message_request--

我的请求总是返回400 Bad Request错误 . 我已经检查了类似的问题，但还没有能够使这个工作：

任何帮助或建议将不胜感激 . 谢谢！

    好吧，400 BadRequest错误似乎是由字符串模板中的换行符空格引起的 . 删除空白使一切工作：

    ...
/* 
  the lack of whitespace is impotant in the folllowing string template:
*/
  _.each(ids, (id) => {
    body = `${body}
--${boundary}
Content-Type: application/http

GET /gmail/v1/users/${userId}/messages/${id.id}? format=metadata&fields=id%2Cpayload`
  });

  body = `${body}
--${boundary}--`;
...

    可能有一种更好的方法来维护代码缩进并消除空白，但我还没有找到它 .
