前阵子网上看到有人写爬取妹子图的派森代码，于是乎我也想写一个教程，确切地说我也想看妹子，哈哈哈，开个玩笑,不过很多教程都是调用的第三方模块，今天就给大家开开荤，使用原生库来爬，并且扩展实现了图片鉴定，图片去重等操作，经过了爬站验证，稳如老狗，我已经爬了几万张了,只要你硬盘够大。
作者忠告：我们是研究技术的，请勿沉迷，沉迷伤身，营养跟不上 O(∩_∩)O~
今天就来个最简单的吧，网站走起 https://www.meitulu.com/ 先分析页面结构，图片URL每次递增，从第二个开始。
Python 多线程实现爬取妹子图
前端，被一个 img标签包起来 <img src="https://mtl.gzhuibei.com/images/img/10431/5.jpg" alt= 直接正则匹配

先来生成页面链接，代码如下
# 传入参数,对页面进行拼接并返回列表
def SplicingPage(page,start,end):
url = []
for each in range(start,end):
temporary = page.format(each)
url.append(temporary)
return url
# 通过内置库,获取到页面的URL源代码
def GetPageURL(page):
head = GetUserAgent(page)
req = request.Request(url=page,headers=head,method="GET")
respon = request.urlopen(req,timeout=3)
if respon.status == 200:
html = respon.read().decode("utf-8")
return html
page_list = SplicingPage(str(args.url),2,100)
for item in page_list:
respon = GetPageURL(str(item))
subject = re.findall('<img src="([^"]+\.jpg)"',respon,re.S)
for each in subject:
img_name = each.split("/")[-1]
img_type = each.split("/")[-1].split(".")[1]
save_name = str(random.randint(1111111,99999999)) + "." + img_type
print("[+] 原始名称: {} 保存为: {} 路径: {}".format(img_name,save_name,each))

Python 多线程实现爬取妹子图
运行结果，就是这样，同学们，都把裤子给我穿上！好好学习！
Python 多线程实现爬取妹子图
接着我们来扩展一个知识点，如何使用Python实现自动鉴别图片，鉴别黄色图片的思路是，讲图片中的每一个位读入内存然后将皮肤颜色填充为白色，将衣服填充为黑色，计算出整个人物的像素大小，然后计算身体颜色与衣服的比例，如果超出预定义的范围则认为是黄图，这是基本的原理，实现起来需要各种算法的支持，Python有一个库可以实现 pip install Pillow porndetective 鉴别代码如下。
Python 多线程实现爬取妹子图
>>> from porndetective import PornDetective
>>> test=PornDetective("c://1.jpg")
>>> test.parse()
c://1.jpg JPEG 1600×2400: result=True message='Porn Pic!!'
<porndetective.PornDetective object at 0x0000021ACBA0EFD0>
>>>
>>> test=PornDetective("c://2.jpg")
>>> test.parse()
c://2.jpg JPEG 1620×2430: result=False message='Total skin percentage lower than 15 (12.51)'
<porndetective.PornDetective object at 0x0000021ACBA5F5E0>
>>> test.result
False
Python 多线程实现爬取妹子图
他这个库使用的算法有一些问题，如果照这样来分析，那肚皮舞之类的都会被鉴别为黄图，而且一般都会使用机器学习识别率更高，这种硬编码的方式一般的还可以，如果更加深入的鉴别根本做不到，是不是黄图，不能只从暴露皮肤方面判断，还要综合考量，姿势，暴露尺度，衣服类型，等各方面，不过这也够用，如果想要在海量图片中筛选出比较优质的资源,你可以这样来写。
from PIL import Image
import os
from porndetective import PornDetective
if __name__ == "__main__":
img_dic = os.listdir("./meizitu/")
for each in img_dic:
img = Image.open("./meizitu/{}".format(each))
width = img.size[0] # 宽度
height = img.size[1] # 高度
img = img.resize((int(width*0.3), int(height*0.3)), Image.ANTIALIAS)
img.save("image.jpg")
test = PornDetective("./image.jpg")
test.parse()
if test.result == True:
print("{} 图片大赞,自动为你保留.".format(each))
else:
print("----> {} 图片正常,自动清除,节约空间,存着真的是浪费资源老铁".format(each))
os.remove("./meizitu/"+str(each))
Python 多线程实现爬取妹子图
妹子图去重，代码如下，这个代码我写了好一阵子，一开始没思路，后来才想到的，其原理是利用CRC32算法，计算图片hash值，比对hash值，并将目录与hash关联，最后定位到目录，只删除多余的图片，保留其中的一张，这里给出思路代码。
import zlib,os
def Find_Repeat_File(file_path,file_type):
Catalogue = os.listdir(file_path)
CatalogueDict = {} # 查询字典,方便后期查询键值对对应参数
for each in Catalogue:
path = (file_path + each)
if os.path.splitext(path)[1] == file_type:
with open(path,"rb") as fp:
crc32 = zlib.crc32(fp.read())
# print(" 文件名: {} CRC32校验: {}".format(path,str(crc32)))
CatalogueDict[each] = str(crc32)
CatalogueList = []
for value in CatalogueDict.values():
# 该过程实现提取字典中的crc32特征组合成列表 CatalogueList
CatalogueList.append(value)
CountDict = {}
for each in CatalogueList:
# 该过程用于存储文件特征与特征重复次数,放入 CountDict
CountDict[each] = CatalogueList.count(each)
RepeatFileFeatures = []
for key,value in CountDict.items():
# 循环查找字典中的数据,如果value大于1就存入 RepeatFileFeatures
if value > 1:
print("[-] 文件特征: {} 重复次数: {}".format(key,value))
RepeatFileFeatures.append(key)
for key,value in CatalogueDict.items():
if value == "1926471896":
print(" 重复文件所在目录: {}".format(file_path + key))
if __name__ == "__main__":
Find_Repeat_File("D://python/",".jpg?imageMogr2/format/png/interlace/0|watermark/2/text/eHVlbml4aWFuZy5jb20/font/bXN5aGJkLnR0Zg/fontsize/20/fill/IzY2NjY2Ng/dissolve/80/gravity/northeast/dx/10/dy/10")

Python 多线程实现爬取妹子图
经过爬站，之后我们得到了几万张妹子图，但是如果我们想看其中的一个妹子的写真，肿么办？ 接下来登场的是AI人脸识别军团，通过简单地机器学习，识别特定人脸，来筛选我们想要看的妹子图。
