python 的requests如何使用代理，,headers.py

headers.py

import randomfirst_num = random.randint(55, 62)third_num = random.randint(0, 3200)fourth_num = random.randint(0, 140)class FakeChromeUA:    os_type = [                ‘(Windows NT 6.1; WOW64)‘, ‘(Windows NT 10.0; WOW64)‘, ‘(X11; Linux x86_64)‘,                ‘(Macintosh; Intel Mac OS X 10_12_6)‘               ]    chrome_version = ‘Chrome/{}.0.{}.{}‘.format(first_num, third_num, fourth_num)    @classmethod    def get_ua(cls):        return ‘ ‘.join([‘Mozilla/5.0‘, random.choice(cls.os_type), ‘AppleWebKit/537.36‘,                         ‘(KHTML, like Gecko)‘, cls.chrome_version, ‘Safari/537.36‘]                        )headers = {    ‘User-Agent‘: FakeChromeUA.get_ua(),    ‘Accept-Encoding‘: ‘gzip, deflate, sdch‘,    ‘Accept-Language‘: ‘zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3‘,    ‘Accept‘: ‘text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8‘,    ‘Connection‘: ‘keep-alive‘}

　　1.首选定义session

import requestssession=requests.Session()

2.proxy的格式

proxies的格式如下

用户名username、 密码password、 代理地址hogehoge.proxy.jp、 端口号8080

proxy_dict = {    "http": "http://username:[email protected]:8080/",    "https": "http://username:[email protected]:8080/"}

3.接上开始设置headers和url

url="http://www.baidu.cpom"headers=headers(headers.py的字典)req=session.get(url,headers=headers,proxies=proxy_dict)
