使用Selenium和Python搜索Google

Question

我无法通过Selenium进行简单的谷歌搜索,虽然我相信我做得对.我试图遵循Selenium文档,但我认为问题可能是由于python或selenium安装不当造成的.我有很少的蟒蛇知识.这是我的代码:

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

browser = webdriver.Firefox()
browser.get('http://www.google.com')

try:
    element = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID, "gbqfq")))
finally:
browser.quit()

search = browser.find_element_by_name('q')
search.send_keys("google search through python")

这就是终端输出.

finally无论是否有异常,您的 块都将被执行.所以 browser.quit()总是执行.

如果您只想搜索此脚本,将为您执行此操作.

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

browser = webdriver.Firefox()
browser.get('http://www.google.com')

search = browser.find_element_by_name('q')
search.send_keys("google search through python")
search.send_keys(Keys.RETURN) # hit return after you enter search text
time.sleep(5) # sleep for 5 seconds so you can see the results
browser.quit()
