Python采集网站随机header

采集的时候header需要变化否则很容易被网站发现。

其实有个python包可以搞这个 不过有点麻烦，先看这个吧

不废话直接代码：

import random

class UserAgent:
    def __init__(self):
        self.headers = [
            "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36",

        ]

    def get_random_agent(self):
        randdom_agent = random.choice(self.headers)
        return randdom_agent
        pass

    def get_random_header(self, header_url):
        headers = {"Referer": header_url,
                   'User-Agent': random.choice(self.headers)}
        return headers
        pass
