4.浏览器伪装技术

 1.用户伪装

uapools = ["Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/17.17134",
]def ua(uapools):thisua = random.choice(uapools)print(thisua)headers = ('user-agent',thisua)opener = urllib.request.build_opener()opener.addheaders = [headers]urllib.request.install_opener(opener)

2.IPaddress伪装

1. 可以去爬一些免费的 IP

2. 自己去申请（稳定）

thisip = ippools.pop()
proxy = urllib.request.ProxyHandler({"http":thisip})
opener = urllib.request.build_opener(proxy,urllib.request.HTTPHandler)
urllib.request.install_openner(opener)

uapools = ["Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/17.17134",
]ippools = []
def update_ippools(ippools):passdef ua_ip_pools(uapools,iplist=ippools, parameter=0):thisip = ""#参数=0 ipself  参数=1 use ippoolsif (parameter == 0):thisip = "127.0.0.1:8888"elif (parameter == 1 ):if (len(iplist) == 0):update_ippools(iplist)thisip = random.choice(iplist)print('current ip:{}'.format(thisip))ippools.pop(ippools.index(thisip))proxy = urllib.request.ProxyHandler({"http":thisip})thisua = random.choice(uapools)headers = ("user-agent", thisua)opener = urllib.request.build_opener(proxy, urllib.request.HTTPHandler)opener.addheaders = [headers]urllib.request.install_opener(opener)
