Scrapy selenium 设置头部信息headers-------UA

1，PhantomJS

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium import webdriver
dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap['phantomjs.page.settings.userAgent'] = 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.75 Safari/537.36'
browser = webdriver.PhantomJS(desired_capabilities=dcap)
browser.save_screenshot('ctrip.png')(你可以截图下来看看你是不是正常访问页面数据)

2，Chrome

将上面的PhantomJS替换掉就可以。
