新手:网页上有不同的文件,可以按如下方式下载: 1.右键单击文件链接 2.选择"保存链接为" 3.单击"保存"新窗口上的按钮。
我尝试了以下代码(前两个步骤),但它无效:
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys
import time
driver = webdriver.Chrome()
driver.maximize_window()
driver.get('www.example.com')
time.sleep(1)
driver.find_element_by_link_text("MarketFiles/").click()
actionChains = ActionChains(driver)
download_file = "Market_File1.csv"
link = driver.find_element_by_link_text(download_file)
actionChains.context_click(link).send_keys(Keys.ARROW_DOWN).send_keys(Keys.ARROW_DOWN).send_keys(Keys.ARROW_DOWN).send_keys(Keys.ARROW_DOWN).send_keys(Keys.RETURN).perform();
请建议如何使用这3个步骤下载文件。感谢

保存链接将打开无法通过selenium直接控制的系统对话框。
话虽如此,可以在配置文件中配置下载首选项,可以在启动浏览器时使用,在这种情况下,任何点击下载都会根据Chrome配置文件中的首选项保存文件
chromeOptions = webdriver.ChromeOptions()
prefs = {"download.default_directory" : "/some/path"}
chromeOptions.add_experimental_option("prefs",prefs)
chromedriver = "path/to/chromedriver.exe"
driver = webdriver.Chrome(executable_path=chromedriver, chrome_options=chromeOptions)
参考:https://sites.google.com/a/chromium.org/chromedriver/capabilities

根据java,您可以使用以下代码单击“保存为链接”,然后单击“在新窗口中保存”
try {
Robot bot = new Robot();
//location of link on your page
bot.mouseMove(5, 12);
//instigate right click of mouse
bot.mousePress(InputEvent.BUTTON1_MASK);
bot.mouseRelease(InputEvent.BUTTON1_MASK);
Thread.sleep(1000);
/*repeatedly press down arrow untill you reach save as link in context menu*/
bot.keyPress(KeyEvent.VK_DOWN);
Thread.sleep(1000);
bot.keyPress(KeyEvent.VK_DOWN);
Thread.sleep(1000);
bot.keyPress(KeyEvent.VK_DOWN);
Thread.sleep(1000);
bot.keyPress(KeyEvent.VK_DOWN);
//press enter to select save as link
Thread.sleep(1000);
//press enter to press save button on new window
bot.keyPress(KeyEvent.VK_ENTER);
Thread.sleep(1000);
bot.keyPress(KeyEvent.VK_ENTER);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
根据您的问题,您需要python代码,以便您可以使用此链接https://pypi.python.org/pypi/py_robot/0.1
