Day03---元素交互操作

一、自动打开京东搜索蜘蛛侠和龙珠

from selenium import webdriver  # 用来驱动浏览器的
from selenium.webdriver import ActionChains  # 破解滑动验证码的时候用的 可以拖动图片
from selenium.webdriver.common.keys import Keys  # 键盘按键操作
import time


driver=webdriver.Chrome()

try:
    driver.implicitly_wait(10)
    driver.get('http://www.jd.com/')
    time.sleep(5)

    # 点击、清除
    input = driver.find_element_by_id('key')
    input.send_keys('蜘蛛侠')


    # 通过class查找搜索按钮
    search = driver.find_element_by_class_name('button')
    search.click()  # 点击搜素按钮

    time.sleep(3)

    input2 = driver.find_element_by_id('key')
    input2.clear() # 清空输入框

    time.sleep(1)

    input2.send_keys('龙珠')
    input2.send_keys(Keys.ENTER)

    time.sleep(10)

finally:
    driver.close()

二、自动破解滑动验证码

from selenium import webdriver  # 用来驱动浏览器的
from selenium.webdriver import ActionChains  # 破解滑动验证码的时候用的 可以拖动图片
from selenium.webdriver.common.keys import Keys  # 键盘按键操作
import time


driver=webdriver.Chrome()

try:
    driver.implicitly_wait(10)
    driver.get('http://www.runoob.com/try/try.php?filename=jqueryui-api-droppable')
    time.sleep(5)

    # 遗弃方法
    driver.switch_to.frame('iframeResult')
    time.sleep(1)


    # 起始方块id：draggable
    source = driver.find_element_by_id('draggable')

    # 目标方块id：droppable
    target = driver.find_element_by_id('droppable')


    # 方式一：秒移
    # 起始方块瞬间移动到目标方块中
    # 拟定好一个动作，需要调用执行方法perform
    # action.drag_and_drop(source,target).perform()
    #
    # time.sleep(10)


    print(source.size)      # 大小
    print(source.tag_name)  # 标签名
    print(source.text)      # 文本
    print(source.location)  # 坐标轴

    # 找到滑动距离
    distance = target.location['x'] - source.location['x']

    # 按住起始滑块
    ActionChains(driver).click_and_hold(source).perform()

    # 方式二：一点一点移
    s=0
    while s<distance:
        ActionChains(driver).move_by_offset(xoffset=2,yoffset=0).perform()
        s += 2

        time.sleep(0.1)

    # 松开起始滑块
    ActionChains(driver).release().perform()

    time.sleep(10)


finally:
    driver.close()

三、执行js代码

# 执行js代码
from selenium import webdriver  # 用来驱动浏览器的
import time

driver = webdriver.Chrome()

try:
    driver.implicitly_wait(10)

    driver.get('http://www.baidu.com/')

    driver.execute_script(
        '''
        alert("湖人总冠军")
       '''
    )

    time.sleep(10)
finally:
    driver.close()

四、模拟浏览器的前进和后退

# 模拟浏览器的前进后退

import time
from selenium import webdriver

browser = webdriver.Chrome()
browser.get('http://www.baidu.com/')
browser.get('http://www.taobao.com/')
browser.get('http://www.sina.com.cn/')

# 回退
browser.back()

time.sleep(3)

# 前进
browser.forward()

time.sleep(3)


browser.close()

五、京东搜索蜘蛛侠，并且列出相关商品的详细信息（初级版）

'''初级版'''
import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys  # 键盘按键操作

driver = webdriver.Chrome()

try:
    driver.implicitly_wait(10)
    # 往京东发送请求
    driver.get('http://www.jd.com/')

    input_tag = driver.find_element_by_id('key')
    input_tag.send_keys('蜘蛛侠')
    input_tag.send_keys(Keys.ENTER)

    time.sleep(5)

    good_list = driver.find_elements_by_class_name('gl-item')
    for good in good_list:
        # print(good)

        # 商品名称
        good_name = good.find_element_by_css_selector('.p-name em').text
        # print(good_name)


        # 商品链接详情页
        good_url = good.find_element_by_css_selector('.p-name a').get_attribute('href')
        # print(good_url)


        # 商品价格
        good_price = good.find_element_by_class_name('p-price').text
        # print(good_price)


        # 商品的评价条数
        good_commit = good.find_element_by_class_name('p-commit').text
        # print(good_comit)

        good_content = f'''
        商品名称：{good_name}
        商品链接：{good_url}
        商品价格：{good_price}
        商品评价条数：{good_commit}
        \n
        '''

        print(good_content)

        with open('jd.txt', 'a',encoding='utf-8')as f:
            f.write(good_content)

    print('商品写入成功！')

finally:
    driver.close()

六、京东搜索蜘蛛侠，并且列出相关商品的详细信息（狂暴版）

'''狂暴版'''

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

def get_good(driver):
    num=1
    try:
        time.sleep(10)

        # 下拉滑动5000px
        js_code='''
            window.scrollTo(0,5000)
        '''
        driver.execute_script(js_code)

        # 等待5秒，待商品数据加载
        time.sleep(10)
        good_list = driver.find_elements_by_class_name('gl-item')
        for good in good_list:
            # 商品名称
            good_name = good.find_element_by_css_selector('.p-name em').text

            # 商品链接
            good_url = good.find_element_by_css_selector('.p-name a').get_attribute('href')

            # 商品价格
            good_price = good.find_element_by_class_name('p-price').text
