selenimu学习二

1、上传文件

from selenium import webdriver
import time
import os

driver = webdriver.Chrome()
src_file = "file:///" + os.path.abspath("test.html")

driver.get(src_file)

while True:
    ele = driver.find_element_by_name("selenium_upload").send_keys(os.path.abspath("test.html"))
    time.sleep(5)

    driver.close()

　　

2、使用chrom浏览器器实现下载操作

# chrom浏览器实现下载操作
from selenium import webdriver

from time import sleep
options = webdriver.ChromeOptions()
prefs = {'profile.default_content_settings.popups': 0, 'download.default_directory': 'e:\'}
# profile.default_content_settings.popups:禁止弹出窗口
# download.default_directory:设置下载路径
options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome()
driver.get('https://pypi.org/project/selenium/#files')
driver.find_element_by_link_text('selenium-3.13.0.tar.gz').click()
sleep(13)
driver.quit()

　　

3、操作cookies

from selenium import webdriver

driver = webdriver.Chrome()

driver.get("https://www.cnblogs.com/")


# 1、获取所有的cookies信息
print(driver.get_cookies())

driver.add_cookie(
    {
        "name":"dsb",
        "value":"xsb"
    }
)

print(driver.get_cookies())

# 通过name属性删除单个cookie
driver.delete_cookie("dsb")

# 通过name属性查看单个cookie的信息
print(driver.get_cookie("dsb"))

# 删除所有的cookies
driver.delete_all_cookies()
print(driver.get_cookies())

driver.close()

　　

4、操作滚动条

操作滚动条
from selenium import webdriver
driver = webdriver.Chrome()

driver.get("https://www.baidu.com")

driver.find_element_by_id("kw").send_keys("selenium")
driver.find_element_by_id("su").click()

# top = "var q=document.documentElement.scrollTop={height}".format(height=10000)
top="var q=document.body.scrollTop=10000"
# middle = "var q=document.documentElement.scrollTop={height}".format(height=0)
middle="var q=document.body.scrollTop=0"

driver.execute_script(top)
import time
time.sleep(5)

driver.execute_script(middle)
time.sleep(5)
driver.close()

　　

5、截图

selenium实现截图
from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window()

driver.get("https://www.baidu.com")

try:
    driver.find_element_by_id("kw").send_keys("selenium")
except Exception as e:
    print(e)
else:
    driver.get_screenshot_as_file("kw.png")

finally:
    driver.close()
