Selenium之PhantomJS相关设置

设置PhantomJS请求头

默认情况下：

from selenium import webdriver
import time

driver = webdriver.PhantomJS()
driver.get('http://httpbin.org/user-agent')
print(driver.page_source)
driver.close()

设置User-Agent

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

user_agent = "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.3 Safari/537.36"

dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = user_agent
dcap["phantomjs.page.customHeaders.User-Agent"] = user_agent

driver = webdriver.PhantomJS(desired_capabilities=dcap)
driver.get('http://httpbin.org/user-agent')
print(driver.page_source)
driver.close()

User-Agent已经变成指定的内容

设置PhantomJS不加载图片

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

SERVICE_ARGS = ['--load-images=false', '--disk-cache=true','--ignore-ssl-errors=true']

driver = webdriver.PhantomJS(service_args=SERVICE_ARGS)
driver.get('https://www.baidu.com')
driver.save_screenshot('baidu.png')
driver.close()

SERVICE_ARGS 常用的参数
