Python的验证码识别，模拟ajax请求，爬取优酷会员（滑稽）

首先想写一个爬取一个网站的优酷会员分享，但是是要输入验证码。
首先，我用谷歌分析其验证码的请求。

然后拼接url 去访问发现做了限制

那么应该是做了检测对请求头。
复制刷新验证码图片的请求头。自己构造个请求，并写出图片

def getyzm():
    headers={
    'Accept-Encoding':'gzip, deflate, sdch',
    'Accept-Language':'zh-CN,zh;q=0.8',
    'Connection':'keep-alive',
    #Cookie:PHPSESSID=d763fd34e25925880c490955de8e0f2c
    'Host':'vip.cengfan6.com',
    'Referer':'http://vip.cengfan6.com/y/',
    'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.75 Safari/537.36',
    'X-Requested-With':'XMLHttpRequest'
    }
    i =random.randint(1,999999)
    print(i)
    url='http://vip.cengfan6.com/y/../code.php?s=%i' %i
    html = requests.get(url,headers=headers)
    #写出图片
    with open('yzm.png','wb') as f:
        f.write(html.content)

然后就是验证码识别了。开始用的pyteeser。真不是很好安装（苦笑）

太麻烦了，然后用的 pytesseract

测试

import pytesseract
from PIL import Image

image = Image.open('c:/yzm.png')
code = pytesseract.image_to_string(image)
print(code)

啊，识别出了英文。我的是数字啊orz

想了下要么看下机器学习训练下。啊，我不会啊，要学！

先用人工的把（伤心）

#识别验证码
def viewyzm():
    print('please input yanzhengma')
    time.sleep(2)
    image = Image.open('yzm.png')
    image.show()
    yzm = raw_input(u'关闭图片才能输入')
    print(yzm)
getyzm()
viewyzm()

后面又遇到了ajax请求。
谷歌看到请求
很有意思的是，刷新页面请求的是历史记录，先获取之前获取的账号密码。
我写了两个函数，一个是请求新的账号密码和请求历史记录的账号密码。
网站做了限制，只能获取5个。我做了代理还是只能5个。what？不是对ip做了限制？

def  get_vip():
    #请求，但是没有解密，可以在历史记录中获取获取到的vip账号
    headers={
    'Accept-Encoding':'gzip, deflate, sdch',
    'Accept-Language':'zh-CN,zh;q=0.8',
    'Connection':'keep-alive',
    #'Cookie':PHPSESSID=d3a9d9a7a9ad9fee71a9588773388ead
    'Host':'vip.cengfan6.com',
    'Referer':'http://vip.cengfan6.com/y/',
    'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.75 Safari/537.36',
    'X-Requested-With':'XMLHttpRequest'
    }
    proxies={
        '117.90.6.65':9000
    }
    vip_url='http://vip.cengfan6.com/ajax.php?code=%s &typename=2' %viewyzm()
    viphtml  = requests.get(vip_url,headers=headers,proxies=proxies)
    print(viphtml.content)
def get_host_vip():
    proxies={
        '117.90.6.65':9000
    }
    vip_url= 'http://vip.cengfan6.com/ajax_jilu.php?viptype=2'
    viphtml  = requests.get(vip_url,proxies=proxies)
    vips =re.findall('
优酷（土豆）帐号：(.+?)密码：(.+?)
',viphtml.content)
    for vip in vips:
        print(vip[0]+":"+vip[1])

应该是我设置代理的方式有误。
不过5个也是够的。我经常用这个网站的会员。手动滑稽

真的不是为了这个获取会员而做的。主要想多写些东西。不写就容易忘。
