The method of setting header in Selenium PhantomJs under Python

code

Not much to say, go directly to the code

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

def getSource(url):
   
    headers = {
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
        'Accept-Language': 'zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3',
        'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.104 Safari/537.36 Core/1.53.4882.400 QQBrowser/9.7.13059.400',
        'referer':'http://www.taobao.com'
    }
    #使用copy()防止修改原代码定义dict
    cap = DesiredCapabilities.PHANTOMJS.copy() 

    for key, value in headers.items():
        cap['phantomjs.page.customHeaders.{}'.format(key)] = value

    # 不载入图片，爬页面速度会快很多
    cap["phantomjs.page.settings.loadImages"] = False

    driver = webdriver.PhantomJS(desired_capabilities=cap)
    driver.get(encodeUrl(url))

Some blog posts mentioned that this method is used to set User-Agent, and it seems to be possible:

cap["phantomjs.page.settings.userAgent"] = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.104 Safari/537.36'

 

an examination

Visit the following URL, you can echo the data you requested to check whether the set header is valid:

For example, I use the above code to access this address, followed by two Experimental parameters:
