python的selenium"send_keys"与chrome驱动程序删除字符

Question

我在Windows 7中使用带有Python(https://pypi.python.org/pypi/selenium)的selenium包.当我尝试登录我的facebook帐户时,我使用send_keys命令,例如

elem = browser.find_element_by_name("email")
elem.send_keys(email);
elem = browser.find_element_by_name("pass")
elem.send_keys(password);

登录失败显然是因为第二个send_keys删除了密码的第一个字符(我通过直接将密码字符发送到电子邮件字段找到了这个.

这是怎么回事？为什么selenium不能像将密钥发送到输入字段那样简单？这是一种由Facebook编码的拒绝自动脚本的保护措施吗？

试图发送整个字母表得到这个:

abcdefghijklmnopqrstuvwxyzBCDFGIKLNOQSTWX

注意缺少多少个字符......

更新

显然这个问题与facebook无关,而与Chrome驱动程序无关.

如果我发送以下简单代码

browser = webdriver.Chrome()
browser.get("https://www.google.com") # Load page
elem = browser.find_element_by_name("q") # Find the query box
query= "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
elem.send_keys(query)

使用chrome驱动程序,我得到BCDFGIKLNOQSTWX注意A,E,H ... Y,Z是如何丢失使用firefox驱动程序(替换browser = webdriver.Chrome()为browser = webdriver.Firefox()我得到:ABCDEFGHIJKLMNOPQRSTUVWXYZ

在python中使用selenium Ide并导出测试用例

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

class Test1(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "https://www.facebook.com/"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_1(self):
        driver = self.driver
        driver.get(self.base_url + "/")
        driver.find_element_by_id("email").clear()
        driver.find_element_by_id("email").send_keys("username")
        driver.find_element_by_id("pass").clear()
        driver.find_element_by_id("pass").send_keys("password")
        driver.find_element_by_id("u_0_b").click()
        driver.find_element_by_xpath("//div[@id='u_ps_0_1_5']/div/div").click()
        driver.find_element_by_link_text("1 Requests").click()
        driver.find_element_by_id("globalContainer").click()

    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()
