在Python中使用代理运行Selenium Webdriver

问题描述

我正在尝试在Python中运行Selenium Webdriver脚本来执行一些基本任务.通过Selenium IDE接口运行机器人时，我可以使它运行正常(即:仅使GUI重复我的操作时).但是，当我将代码导出为Python脚本并尝试从命令行执行时，Firefox浏览器将打开，但无法访问起始URL(错误返回到命令行，程序停止).无论我尝试访问哪个网站，都在发生这种情况.

I am trying to run a Selenium Webdriver script in Python to do some basic tasks. I can get the robot to function perfectly when running it through the Selenium IDE inteface (ie: when simply getting the GUI to repeat my actions). However when I export the code as a Python script and try to execute it from the command line, the Firefox browser will open but cannot ever access the starting URL (an error is returned to command line and the program stops). This is happening me regardless of what website etc I am trying to access.

出于演示目的，我在此处包括了一个非常基本的代码.我认为我没有正确包含代码的代理部分，因为返回的错误似乎是由代理生成的.

I have included a very basic code here for demonstration purposes. I don't think that I have included the proxy section of the code correctly as the error being returned seems to be generated by the proxy.

任何帮助将不胜感激.

Any help would be hugely appreciated.

以下代码仅用于打开www.google.ie并搜索硒"一词.对我来说，它打开了一个空白的Firefox浏览器并停止.

The below code is simply meant to open www.google.ie and search for the word "selenium". For me it opens a blank firefox browser and stops.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
import unittest, time, re
from selenium.webdriver.common.proxy import *

class Testrobot2(unittest.TestCase):
    def setUp(self):

        myProxy = "http://149.215.113.110:70"

        proxy = Proxy({
        'proxyType': ProxyType.MANUAL,
        'httpProxy': myProxy,
        'ftpProxy': myProxy,
        'sslProxy': myProxy,
        'noProxy':''})

        self.driver = webdriver.Firefox(proxy=proxy)
        self.driver.implicitly_wait(30)
        self.base_url = "https://www.google.ie/"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_robot2(self):
        driver = self.driver
        driver.get(self.base_url + "/#gs_rn=17&gs_ri=psy-ab&suggest=p&cp=6&gs_id=ix&xhr=t&q=selenium&es_nrs=true&pf=p&output=search&sclient=psy-ab&oq=seleni&gs_l=&pbx=1&bav=on.2,or.r_qf.&bvm=bv.47883778,d.ZGU&fp=7c0d9024de9ac6ab&biw=592&bih=665")
        driver.find_element_by_id("gbqfq").clear()
        driver.find_element_by_id("gbqfq").send_keys("selenium")

    def is_element_present(self, how, what):
        try: self.driver.find_element(by=how, value=what)
        except NoSuchElementException, e: return False
        return True

    def is_alert_present(self):
        try: self.driver.switch_to_alert()
        except NoAlertPresentException, e: return False
        return True

    def close_alert_and_get_its_text(self):
        try:
            alert = self.driver.switch_to_alert()
            alert_text = alert.text
            if self.accept_next_alert:
                alert.accept()
            else:
                alert.dismiss()
            return alert_text
        finally: self.accept_next_alert = True

    def tearDown(self):
        self.driver.quit()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    unittest.main()

推荐答案

以这种方式为我工作(类似于@Amey和@ user4642224代码，但要短一点):

Works for me this way (similar to @Amey and @user4642224 code, but shorter a bit):

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

prox = Proxy()
prox.proxy_type = ProxyType.MANUAL
prox.http_proxy = "ip_addr:port"
prox.socks_proxy = "ip_addr:port"
prox.ssl_proxy = "ip_addr:port"

capabilities = webdriver.DesiredCapabilities.CHROME
prox.add_to_capabilities(capabilities)

driver = webdriver.Chrome(desired_capabilities=capabilities)
