前序
好感人的程序员礼物，甩饼的女朋友都感动哭惹
数据准备
1.爬虫下载每日告白图片
2.爬取解析每日天气数据
3.SMTP发送给自己女朋友
4.把python代码做成脚本，发布至服务器，设置每日定时发送
1.爬虫下告白图片
这里使用（https://www.douban.com/photos/album/157693223/?m_start=0）提供的表白图片
代码：
import requests
from lxml import etree
import os
import time
def write_name(name): #将所有下载的图片名保存到一个txt
with open('picLibs/name.txt','a') as f:
text =name+'\n'
f.write(text)
print(name+' 输入到txt成功！')
if __name__ == '__main__':
if not os.path.exists('./picLibs'): #创建图片存储文件夹
os.mkdir('./picLibs')
url = 'https://www.douban.com/photos/album/157693223/?m_start=' #爬取图片的url
headers = { #规避反robot协议
'Connection': 'Keep-Alive',
'User-Agent': 'Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)',
}
for i in range(18):
real_url = ''
real_url = url+str(i*17)
page_text = requests.get(url=real_url,headers=headers).text
tree = etree.HTML(page_text)
url_list = tree.xpath('//*[@id="content"]/div[3]/div[1]/div[2]/div/a/img/@src')
for image in url_list:
img_name = image.split('/')[-1] #获取文件名
img_data = requests.get(url=image, headers=headers).content
img_path = 'picLibs/' + img_name #拼接图片存储路径
write_name(img_name)
with open(img_path, 'wb') as fp: #二进制写入本地
fp.write(img_data)
print(img_name, '下载成功！！！')
time.sleep(1) #主线程休眠一秒，规避检测
print('全部下载完成！')
爬取下来就是这样
2.爬取解析每日天气数据
因为甩饼女票在湘潭，所以拿湘潭举例，换城市只需要换URL的城市编码就好
爬取的数据来源于：中国天气网 http://www.weather.com.cn/weather1d/101250201.shtml
可以看到中国天气网，温度模块、生活指数模块的数据，对我们比较有用
经过抓包分析后，还能发现这两个模块的数据是静态加载出来的，这就很nice了，直接用xpath解析就好
3.SMTP发送给自己女朋友
4.把python代码做成脚本，发布至服务器，设置每日定时发送
直接上代码吧
