当我发送密钥时，Selenium 不会将文本复制到剪贴板

Question

这是几周前的工作，我正在测试的网站没有改变任何东西。有时它会突出显示我需要的文本，但不会将其复制到剪贴板，有时它会起作用；现在很少，但每次我写它时它都能正常工作，而且没有做 time.sleep()。不过，我现在开始收到一条错误消息。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

driver = webdriver.Firefox()
driver.get("http://www.speedyshare.com/")

driver.switch_to.frame(0)

upload_input = driver.find_element_by_css_selector(
"#selectfilebox input[type=file]")
upload_input.send_keys("/home/ro/Documents/Aaatrack.pdf")

upload_button = driver.find_element_by_link_text("Upload")
upload_button.click()

element = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.CLASS_NAME, "inpfilelink")))

elem = driver.find_element_by_class_name("inpfilelink")
elem.send_keys(Keys.CONTROL, "a")
time.sleep(3)
elem.send_keys(Keys.CONTROL, "c")

这是我有时会遇到的错误

我已经用 firebug 检查了该元素，它仍然存在同名。

Problems happens because when you hover over the Download link, an alert pops up and shows 立即按 CTRL + C 复制到剪贴板。

对我来说，下面的代码非常棒！-

它打印上传文档的网络共享链接并将复制的链接粘贴到下面的文本区域//*[@id='linklisttextarea']。所以它变成了四倍！

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

driver = webdriver.Firefox()
driver.get("http://www.speedyshare.com/")
driver.maximize_window()
driver.switch_to.frame(0)

upload_input = driver.find_element_by_css_selector(
"#selectfilebox input[type=file]")
upload_input.send_keys("C:\abc.pdf")

upload_button = driver.find_element_by_link_text("Upload")
upload_button.click()

element = WebDriverWait(driver, 100).until(EC.visibility_of_element_located((By.XPATH, "//*[@id='linklisttextarea']")))

elem = driver.find_element_by_xpath("//td[contains(text(),'Download Link:')]/following-sibling::td[1]/input")
share_lnk =elem.get_attribute('value')
print share_lnk
lnk = driver.find_element_by_xpath("//input[@class='inpfilelink']")
print "Your web linkk is %s"%(lnk.get_attribute('value'))
txt = driver.find_element_by_xpath("//*[@id='linklisttextarea']")
txt.send_keys(share_lnk)
txt.send_keys(share_lnk)
txt.send_keys(share_lnk)
txt.send_keys(share_lnk)
driver.quit()
