Answer 1

这样做的一种方法是首先列出消息：

GET https://www.googleapis.com/gmail/v1/users/me/messages

<强>响应：

{
 "messages": [
  {
   "id": "14f60b097be71757",
   "threadId": "14f60b097be71757"
  },
  {
   "id": "14f603ead78aff97",
   "threadId": "14f603ead78aff97"
  }, ...

然后，获取您想要的消息，并只询问Message-Id - 标题：

format = metadata
metadataHeaders = Message-Id

GET https://www.googleapis.com/gmail/v1/users/me/messages/14f60b097be71757?format=metadata&metadataHeaders=Message-Id
