Question

我试图使用无头浏览器。但是，当我尝试.sendkeys到xpath选择器时，我一直收到错误。

from selenium import webdriver
import time
from selenium.webdriver.common.keys import Keys
import time



driver=webdriver.PhantomJS("C:\\Users\\ikhan\\AppData\\Local\\Programs\\Python\\Python36-32\\selenium\\webdriver\\phantomjs.exe")
driver.maximize_window()
driver.set_page_load_timeout(30)
driver.implicitly_wait(20)
driver.get("https://google.com")
driver.find_element_by_xpath('''//*[@id="lst-ib"]''').send_keys("anish")
driver.find_element_by_xpath('''//*[@id="lst-ib"]''').send_keys(Keys.RETURN)

driver.close()

我收到以下错误：

    Traceback (most recent call last):

Screenshot: available via screen

我尝试使用Chrome浏览器使用此代码，它运行正常。我也尝试过使用id选择器。

要找到Google搜索框，请按以下方式使用name定位器：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.PhantomJS(executable_path="C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe")
driver.get("https://google.com")
google_search = driver.find_element_by_name("q")
google_search.send_keys("anish")
google_search.send_keys(Keys.RETURN)
print("Google Search Complete")
