Python Selenium将照片上传到Facebook

Question

我已经尝试了很多次试图将照片上传到Facebook的文章。当我读了硒文档中的所有它说是

选择<input type="file">元素，并调用send_keys()方法传递文件路径，相对要么路径测试脚本，或绝对路径。

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

usr = "random@gmail.com" 
pwd = "randompassword" 

driver = webdriver.Firefox() 
# or you can use Chrome(executable_path="/usr/bin/chromedriver") 
driver.get("http://www.facebook.com/login") 
assert "Facebook" in driver.title 
elem = driver.find_element_by_id("email") 
elem.send_keys(usr) 
elem = driver.find_element_by_id("pass") 
elem.send_keys(pwd) 
elem.send_keys(Keys.RETURN) 
elem = driver.find_element_by_css_selector("#u_0_y") 
elem.send_keys("Hello Internet :) ") 
driver.find_element_by_css_selector("._11b").click() 

Answer 1

而不是使用css_selector，尽量使用XPath。
