推荐答案

列表消息仅返回消息ID和线程ID，而不是全部内容(因为这可能是一封完整的电子邮件，可能很大，如25MB).因此，如果您需要所有这些信息，请在循环中调用messages.get().如果只需要标题如收件人"，发件人"，主题"，则可以调用messages.get(format = METADATA)，也可以使用您正在使用的语言.

List message just returns the message Ids and thread ids, not the full content (since that could be an entire email which could be huge like 25MB). So if you want certain info on all of them then call messages.get() in the loop. If you only want headers like To, From, Subject then you can call messages.get(format=METADATA), or however it looks in the language you're using.
