Question

我正在尝试使用Selenium / BeautifulSoup对网页进行单元测试。我收到了一个错误，虽然我无法使用谷歌。

selenium.common.exceptions.WebDriverException: Message: ''

我使用的是便携版Firefox和代理。

import urllib2
from bs4 import BeautifulSoup
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 time
import sys

def getItemDivs(url):
    profile = webdriver.FirefoxProfile()
    profile.set_preference("general.useragent.override","Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/21.0")
    profile.set_preference("network.proxy.http", "proxy.example.com")

    ffbin = webdriver.firefox.firefox_binary.FirefoxBinary('C:\\FirefoxPortable\\App\\Firefox\\firefox.exe')

    # IT FAILS ON THE NEXT LINE
    driver=webdriver.Firefox(profile, firefox_binary=ffbin)
    driver.implicitly_wait(30)

    # THIS LINE CONTAINS A VALID COOKIE, BUT IT HAS BEEN REMOVED FOR THIS QUESTION.
    driver.add_cookie(<<mycookie>>)
    base_url = url
    verificationErrors = []
    accept_next_alert = True

    driver.get(base_url)
    scrap1 = driver.page_source
    soup = BeautifulSoup(scrap1)

这个问题类似于this one，但是，在这个问题中，他们首次请求成功。我没有成功。

什么可能导致此类异常但将消息留空？

Answer 1

问题在于我没有设置network.proxy.port。添加此行解决了问题：

profile.set_preference("network.proxy.port", "80")

Selenium WebDriverException中的空错误消息
