python-selenium-动作链拖拽；cookies处理

1:动作链拖拽

导入动作链需要的包

from selenium.webdriver import ActionChains

具体步骤

    #1:创建动作链对象,并绑定给浏览器
    action = ActionChains(driver)
    # 2:点击并长按指定标签
    action.click_and_hold(div)
    # perform:使动作链对象立即执行  move_by_offset(x,y)->方向坐标,传入像素
    action.move_by_offset(260, 1).perform()
    # 释放鼠标
    ActionChains(driver).release().perform()

具体代码

from selenium import webdriver
import time
from selenium.webdriver.common.by import By
# 动作链
from selenium.webdriver import ActionChains

driver = webdriver.Chrome()
driver.get("https://www.runoob.com/try/try.php?filename=jqueryui-api-droppable")
driver.implicitly_wait(30)
# 要定位的元素在iframe里面,所以要先进去iframe里
# 进入框架
driver.switch_to.frame(driver.find_element(By.ID, 'iframeResult'))
div = driver.find_element(By.XPATH, '//*[@id="draggable"]')  # 原位置
"""开始动作链---滑动"""


def demo_01():
    """方法1"""
    # 方法1:方法一移动滑块，此方法一瞬间移动过去，不建议使用
    # 执行拖动或者时滑动操作,基于动作链的实现

    # 1:创建动作链对象,并绑定给浏览器
    action = ActionChains(driver)
    # 2:点击并长按指定标签
    action.click_and_hold(div)
    # perform:使动作链对象立即执行  move_by_offset(x,y)->方向坐标,传入像素
    action.move_by_offset(260, 1).perform()
    # #释放动作链对象
    # action.release()
    # 释放鼠标
    ActionChains(driver).release().perform()
    # 切换到弹窗视角
    alert = driver.switch_to.alert
    print(f"弹窗的title是:{alert.text}")
    # 点击确定
    alert.accept()


def demo_02():
    """方法二"""
    # 方法二：按照偏移量进行移动，此刻移动滑块是水平向右移动
    # 创建动作链对象, 并绑定给浏览器,点击并长按指定标签,perform:使动作链对象立即执行
    ActionChains(driver).click_and_hold(div).perform()
    # 偏移量的计算是目标位置x轴的值减去要移动的滑块的x轴的值
    Target = driver.find_element(By.XPATH, '//*[@id="droppable"]')  # 目标值
    source = driver.find_element(By.XPATH, '//*[@id="draggable"]')  # 原位置
    offset = Target.location["x"] - source.location["x"]
    i = 0
    # 模拟缓慢的滑动
    while i <= offset:
        #time.sleep(0.1)   #x的像素不能传的太大,否则补捉不到了
        ActionChains(driver).move_by_offset(10, 0).perform()
        i += 10
    # 释放鼠标
    ActionChains(driver).release().perform()
    # 切换到弹窗视角
    alert = driver.switch_to.alert
    print(f"弹窗的title是:{alert.text}")
    # 点击确定
    alert.accept()
demo_02()
time.sleep(100)

2:selenium关于cookies的处理     

有时候网站需要检查我们的cookies,在遇到了cookies是变化的,复杂的我们不像使用js逆向来处理.

这时候selenium是一个不错的选择

1:我们需要先点击浏览器的开发者工具

 2:name是cookies的键;value是cookies的值

 3:通过的方式来获取cookies,但是发现他的格式不对

json_cookies=driver.get_cookies()
    print(json_cookies)

推荐js格式化代码的网站

https://www.qianbo.com.cn/Tool/Beautify/Js-Formatter.html

4:通过代码把cookies变为字典的形式

 json_cookies=driver.get_cookies()
    dic={}
    for i in json_cookies:
        dic[i["name"]]=i["value"]
    return dic

 这时候cookies的形式为字典

注意:不能直接放在请求头里面,因为他现在是字典的形式

        'Cookie':cookies
    }
    resp=requests.get(url=url,headers=headers).text

"""不能这么写"""

应该将cookies直接放在request里面

  url="https://user.17k.com/ck/author/shelf?page=1&appKey=2406394919"
    headers={
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36",
        
    }
    resp=requests.get(url=url,headers=headers,cookies=cookies).text
