selenium.webdriver中添加代理

Firefox中设置代理ip
　　method_1
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference(‘network.proxy.type’, 1)
profile.set_preference(‘network.proxy.http’, ‘127.0.0.1’)
profile.set_preference(‘network.proxy.http_port’, 17890) # int
profile.update_preferences()
driver = webdriver.Firefox(firefox_profile=profile)
driver.get(‘http://httpbin.org/ip‘)
　　method_2
from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy
from selenium.webdriver.common.proxy import ProxyType
proxy = Proxy(
{

‘proxyType’: ProxyType.MANUAL, # 用不用都行

‘httpProxy’: get_proxy_ip_port()
}
)
driver = webdriver.Firefox(proxy=proxy)
driver.get(‘http://httpbin.org/ip‘)
　　phantomjs中设置代理ip
　　方法一：太不优雅（还是看方法二吧）
　　在phantomjs中不能像上面的Firefox的method2一样传入proxy
　　phantomjs和Firefox均继承自WebDriver，父类WebDriver可以传入proxy
　　phantomjs在初始化WebDriver时就没有留proxy参数
　　所以可以像下图一样改一下phantomjs类的源码，就可以在phantomjs中传入proxy参数了

　　下面才是示例
from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy
from selenium.webdriver.common.proxy import ProxyType
proxy = Proxy(
{
‘proxyType’: ProxyType.MANUAL,
‘httpProxy’: get_proxy_ip_port()
}
)
driver = webdriver.PhantomJS(
executable_path=”/path/of/phantomjs”,
proxy=proxy
)
driver.get(‘http://httpbin.org/ip‘)
print driver.page_source
driver.close()
　　方法二：
from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy
from selenium.webdriver.common.proxy import ProxyType
proxy = Proxy(
{
‘proxyType’: ProxyType.MANUAL,
‘httpProxy’: ‘ip:port’ # 代理ip和端口
}
)

新建一个“期望技能”，哈哈

desired_capabilities = DesiredCapabilities.PHANTOMJS.copy()

把代理ip加入到技能中

proxy.add_to_capabilities(desired_capabilities)
driver = webdriver.PhantomJS(
executable_path=”/path/of/phantomjs”,
desired_capabilities=desired_capabilities
)
driver.get(‘http://httpbin.org/ip‘)
print driver.page_source
driver.close()
　　方法三（动态切换ip）：
from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy
from selenium.webdriver.common.proxy import ProxyType
proxy = Proxy(
{
‘proxyType’: ProxyType.MANUAL,
‘httpProxy’: ‘ip:port’ # 代理ip和端口
}
)

新建一个“期望技能”，哈哈

desired_capabilities = DesiredCapabilities.PHANTOMJS.copy()

把代理ip加入到技能中

proxy.add_to_capabilities(desired_capabilities)
driver = webdriver.PhantomJS(
executable_path=”/path/of/phantomjs”,
desired_capabilities=desired_capabilities
)

测试一下

driver.get(‘http://httpbin.org/ip‘)
print driver.page_source

现在开始切换ip

再新建一个ip

proxy = Proxy(
{
‘proxyType’: ProxyType.MANUAL,
‘httpProxy’: ‘ip:port’ # 代理ip和端口
}
)

再新建一个“期望技能”，（）

desired_capabilities = DesiredCapabilities.PHANTOMJS.copy()

把代理ip加入到技能中

proxy.add_to_capabilities(desired_capabilities)

新建一个会话，并把技能传入

driver.start_session(desired_capabilities)
driver.get(‘http://httpbin.org/ip‘)
print driver.page_source
driver.close()
