Python 机械化随机用户代理

我试图让Mechanize在每次打开URL时都使用随机用户代理。 有人能为我指出正确的方向吗？我需要这样做我到处都找遍了，找不到推荐人

谢谢

这为您提供了一个示例用户代理参考。演示它的示例代码：

from random import choice
user_agents = ['Mozilla/5.0 (X11; U; Linux; i686; en-US; rv:1.6) Gecko Debian/1.6-7','Konqueror/3.0-rc4; (Konqueror/3.0-rc4; i686 Linux;;datecode)','Opera/9.52 (X11; Linux i686; U; en)']
random_user_agent = choice(user_agents)

您可以将上述链接中的任意数量的用户_代理包含到变量用户_代理中

现在只需在初始化过程中添加标题，将

随机用户代理

放入Mechanize中。

我在做网络爬虫时遇到了同样的问题，这就是我使用的解决方案：

class URLOpener():      
    def opener(self,user_agent):
        cj=cookielib.CookieJar()
        #Process Hadlers
        opener=urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
        opener.addheaders=[
                        ('User-Agent', user_agent),
                        ('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'),
                        ('Accept-Language', 'en-gb,en;q=0.5'),
                        ('Accept-Charset', 'ISO-8859-1,utf-8;q=0.7,*;q=0.7'),
                        ('Keep-Alive', '115'),
                        ('Connection', 'keep-alive'),
                        ('Cache-Control', 'max-age=0'),
                    ]
        return opener

    #Openers with different User-Agents
    def opener_list(self,f_path):
        #f_path is a path to the file that contains browsers
        f=open(f_path, 'r+')
        count=0
        user_agent_list=list()
        for line in f.xreadlines():
            count+=1
            user_agent_list.append(line[:-1])
        openers=[self.opener(user_agent) for user_agent in user_agent_list]
        return openers

我创建的文件也类似于：
