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()
