详解在selenium中设置代理ip方法

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()
