Selenium Python FirefoxWebDriver处理打开保存对话框

代码如下(网上示例)：

#profile = webdriver.FirefoxProfile(r"C:\Users\Skyyj\AppData\Roaming\Mozilla\Firefox\Profiles\1rzh6139.default")

profile = webdriver.FirefoxProfile()

##设置成0代表下载到浏览器默认下载路径；设置成2则可以保存到指定目录

profile.set_preference("browser.download.folderList", 2)

#这里设置与否不影响，没有发现有什么影响。

#profile.set_preference("browser.download.manager.showWhenStarting", False)

profile.set_preference("browser.download.dir", r"c:\Down")

profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")

#这里设置与否没有发现有什么影响

#profile.set_preference("browser.helperApps.alwaysAsk.force", False);

self.driver = webdriver.Firefox(profile)

自己写的实例(Environment:Python3.6.5+Selenium+PyCharm+Firefox61+FirefoxDriver)：

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

import time,os

profile = webdriver.FirefoxProfile()

#save the file to directory=E:\sli\CIFS2

profile.set_preference("browser.download.dir", r"E:\sli\CIFS2")

profile.set_preference("browser.download.folderList", 2)

profile.set_preference("browser.download.manager.showWhenStarting", False)

#download .zip file

profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/zip")

#driver = webdriver.Firefox(firefox_profile=profile)

driver = webdriver.Firefox(profile)

driver.get("http://10.49.5.8:8080/RLink/login.jsp")

driver.maximize_window()

# -----------------------------------Login Steps----------------------------------------------

# input user name

driver.find_element_by_id("j_username").send_keys("1")

time.sleep(1)

# input password

driver.find_element_by_id("j_password").send_keys("1")

time.sleep(1)

# click "Log in" button

driver.find_element_by_id("buttonSubmit").click()

time.sleep(1)

# -----------------------------------Download Steps----------------------------------------------

time.sleep(2)

# -----------------------------------Logout Steps----------------------------------------------

time.sleep(1)

# click "Log Out"

driver.find_element_by_xpath("//div[text()='Log Out']").click()

time.sleep(1)

# click "Yes" on confirm dialog

driver.find_element_by_xpath('/html/body/div[9]/div/div/div/div[3]/div/div[2]/button[1]').click()

# click "No" on confirm dialog

#driver.find_element_by_xpath('/html/body/div[9]/div/div/div/div[3]/div/div[2]/button[2]').click()

time.sleep(1)

driver.quit()
