使用Ruby IMAP在两个日期之间搜索

Question

我是Ruby的新手，我试图在早上9点到上午11点之间返回电子邮件的数量。

例如。

@received_today = imap.search(["SINCE", @today.strftime("%d-%b-%Y-%H"):"BEFORE", @today.strftime("%d-%b-%Y-%H")]).count.to_s 

我知道这是错误的，但这是我最接近的猜测如何做到这一点。任何帮助将不胜感激。

Answer 1

也许是这样的：

require 'date' 
start_time = Net::IMAP.format_datetime(DateTime.strptime("09:00", "%H:%M")) 
end_time = Net::IMAP.format_datetime(DateTime.strptime("11:00", "%H:%M")) 
@received_today = imap.search(["SINCE", start_time, "BEFORE", end_time ]).count 

UPDATE： 尝试＃2 :)

由于IMAP SEARCH命令忽略自从和前条件的部分时间这应该工作：

require 'date' 

today = Net::IMAP.format_date(Date.today) 

start_time = DateTime.strptime("09:00", "%H:%M") 
end_time = DateTime.strptime("11:00", "%H:%M") 

@received_today = imap.search(["ON", today]) # get sequence nums of todays emails 

# fetch the INTERNALDATE-s and count the ones in the timeframe 
count = imap.fetch(@received_today, "INTERNALDATE").count{ |data| 
    time = DateTime.parse(data.attr["INTERNALDATE"]) 
    time.between? start_time, end_time 
}
