Python硒PhantomJS代理

Question

这是我的代码：

from selenium import webdriver

proxylist=['58.12.12.12:80','69.12.12.12:80']
weblist=['https://www.google.com','https://www.facebook.com','https://www.yahoo.com','https://aol.com']
for s in range (len(proxylist)):
    service_args = ['--proxy=%s'%(proxylist[s]),'--proxy-type=socks5']
    driver = webdriver.PhantomJS('phantomjs.exe', service_args = service_args)
    for s in weblist:
        driver.get(s)

这个想法是浏览器首先将使用proxylist [0]转到那些站点。 如果proxylist [0]在网站[2]上超时，则proxylist [1]将继续对网站[3]进行处理。 我认为我应该使用try和，但不知道将它们放在哪里。 很高兴您提供了帮助！

Answer 1

尝试这样的事情。 基本上，我们要切换内部和外部循环并添加try / except

for s in weblist:
    for s in range (len(proxylist)):
        try

            service_args = ['--proxy=%s'%(proxylist[s]),'--proxy-type=socks5']
            driver = webdriver.PhantomJS('phantomjs.exe', service_args = service_args)
            driver.get(s)
            break
        except TimeOutException:
            print 'timed out'

Answer 2

尝试超时的尝试是这样的：

try:
    driver.set_page_load_timeout(1)
    driver.get("http://www.example.com")
except TimeoutException as ex:
    print("Exception has been thrown. " + str(ex))

对于您的代码，添加它就像：

from selenium import webdriver
from selenium.common.exceptions import TimeoutException

proxylist=['58.12.12.12:80','69.12.12.12:80']
weblist=['https://www.google.com','https://www.facebook.com','https://www.yahoo.com','https://aol.com']


def test():
    temp_count_proxy = 0
    driver_opened = 0
    for url in weblist:
        if temp_count_proxy > len(proxylist):
            print("Out of proxy")
            return

        if driver_opened == 0:
            service_args = ['--proxy={}'.format(proxylist[temp_count_proxy]),'--proxy-type=socks5']
            driver = webdriver.PhantomJS('phantomjs.exe', service_args = service_args)
            driver_opened = 1

        try:
            driver.set_page_load_timeout(2)
            driver.get(url)
        except TimeoutException as ex:
            driver.close()
            driver_opened = 0
            temp_count_proxy += 1
            continue

test()

请注意，好像无法获取一个URL一样，它将更改代理，并获取下一个URL（根据您的要求），但不会获取相同的URL。

如果您希望它在重试当前URL失败后更改代理，请使用以下命令：

from selenium import webdriver
from selenium.common.exceptions import TimeoutException

proxylist=['58.12.12.12:80','69.12.12.12:80']
weblist=['https://www.google.com','https://www.facebook.com','https://www.yahoo.com','https://aol.com']


def test():
    temp_count_proxy = 0
    driver_opened = 0
    for url in weblist:
        while True:

            if temp_count_proxy > len(proxylist):
                print("Out of proxy")
                return

            if driver_opened == 0:
                service_args = ['--proxy={}'.format(proxylist[temp_count_proxy]),'--proxy-type=socks5']
                driver = webdriver.PhantomJS('phantomjs.exe', service_args = service_args)
                driver_opened = 1

            try:
                driver.set_page_load_timeout(2)
                driver.get(url)
                # Your code to process here

            except TimeoutException as ex:
                driver.close()
                driver_opened = 0
                temp_count_proxy += 1
                continue

            break
