西部世界 1080P高清下載和自動提醒后續新出的#
1、主要思路是，通過高清源頭的網站提供的資源，爬取后，通過迅雷實現自動下載，
然后后續新出的，比如下周1更新后，腳本會自動捕捉后發郵件通知，并自動下載。
2、代碼：
# -*- coding: utf-8 -*-
# python 3.5.2
# 測試系統，Win10
# Author:Van
# 實現《西部世界》有更新后自動下載，以及郵件通知
# V1.01
# 修改@href提取方法，因源頭網站變更
# 請把對應的帳號密碼修改成自己的

html = requests.get(url).content.decode('utf-8')
# lxml
selector = etree.HTML(html)
real_link = []
# to be easy, try 'starts-with' , very useful in this case :)
HDTV = selector.xpath('//a[starts-with(@title, "HDTV-1080P")]/text()')
for each in HDTV:
print(each)
# the site modified the magnet link position with adding the span
# we should use: following-sibling function to catch it :)
href = selector.xpath('//a[starts-with(@title, "HDTV-1080P")]/following-sibling::span/a/@href')
print()
print('目前有 %d 集西部世界' %len(href))
print()
for each in href:
# split to get the right magnet link
each = 'magnet' + each.split('magnet')[-1]

if __name__ == '__main__':
# download the exiting series of WestWorld
# send_email('最新更新磁鏈接：'+ str(real_link))
for i in real_link:
addTasktoXunlei(i, course_infos=None)
# to get the later WestWorld for each hour
while 1:
if new_href():
send_email('所有的下載地址（磁鏈接）：'+ str(real_link))
new_download()
time.sleep(15)
# wait for an hour
temp_link = real_link
print(temp_link)
print('神劇很好看吧，親，耐心等下一集！~！')
3、代碼分析，其中用到了deepcopy，這個功能很有用，并配合了2個數組的差集，使得可以規避定時器，而讓腳本直接比較temp_link的內容，而撲捉到網站有新的更新了。另外，在地址識別的時候，一開始用.xpath 沒顯示內容，有點奇怪，后來根據特性，使用了strats_with識別了內容。另外，原始的郵件發送函數，是一個接收人，如果要多發，則receiver的格式為list，并修改 msg['To'] = ','.join(receiver)
4、郵件的作用是可以利用微信綁定來推送，相對短信，更覺方便。
5、感謝：
@陌 提供了163發送email的代碼
@何方 提供了高清網站源
@其他人，交流了細節
6、可改進點：
郵件的地址內容顯示的是一個列表，有待改進。
