在 Scrapy 文档中,有以下示例说明如何在 Scrapy 中使用经过身份验证的会话与登录数据:

class LoginSpider(BaseSpider):
name = 'example.com'
start_urls = ['http://www.example.com/users/login.php']

def parse(self, response):
    return [FormRequest.from_response(response,
                formdata={'username': 'john', 'password': 'secret'},
                callback=self.after_login)]

def after_login(self, response):
    # check login succeed before going on
    if "authentication failed" in response.body:
        self.log("Login failed", level=log.ERROR)
        return

    # continue scraping with authenticated session...

但是有没有办法使用证书登录来进行此身份验证?
