selenium 简单案例＜批量下载文件＞＜网页自动化点击上报＞

一、批量下载文件

网页分析

点击跳转到下载页面

python 复制代码

from selenium import webdriver
import time


def get_link_list():
    # 创建浏览器对象
    driver = webdriver.Chrome(
        executable_path=r'C:\Users\nlp_1\Desktop\chromedriver\chromedriver-win32\chromedriver.exe')
    url = 'https://www.tendacn.com/en/service/download-cata-11.html'
    driver.get(url)
    # 等待
    driver.implicitly_wait(10)
    css_elem = driver.find_elements_by_css_selector('.dr_file > a')
    link_list = []
    for link in css_elem:
        page_link = link.get_attribute('href')
        print(page_link)
        link_list.append(page_link)

    driver.close()
    driver.quit()
    return link_list

def get_download_links(link_list):
    download_link_list = []
    for i,link in enumerate(link_list):
        if i == 0:
            driver = webdriver.Chrome(
        executable_path=r'C:\Users\nlp_1\Desktop\chromedriver\chromedriver-win32\chromedriver.exe')
            driver.get(link)
        else:
            js = f'window.open("{link}")'
            driver.execute_script(js)
            # 每打开一个链接切换到该页面也就是最新的这个
            driver.switch_to.window(driver.window_handles[-1])
        download_elem = driver.find_element_by_css_selector('.downbtns > a')
        download_link = download_elem.get_attribute('href')
        download_link_list.append(download_link)
    totals = len(download_link_list)
    print(f'一共有{totals}个下载链接！')

    driver.quit()
    return download_link_list


def download_file(download_link_List):
    for i,doanload_link in enumerate(download_link_List):
        js = f'window.open("{doanload_link}")'
        driver.execute_script(js)
        print(30*'-')
        print(doanload_link)
        time.sleep(6)
        print(f'第{i + 1}个文件正在下载中......')


# 程序执行入口
if __name__ == '__main__':
    link_list = get_link_list()
    download_link_List = get_download_links(link_list)

    options = webdriver.ChromeOptions()
    options.add_argument('--ignore-certificate-errors')
    driver = webdriver.Chrome(options=options)

    download_file(download_link_List)

二、网页自动化点击上报

python 复制代码

# 指定账户名和密码登录
def login():
    # 随机点一下 ，以便显示登录页面
    driver.find_element_by_id('bodyMain').click()
    # id="username"是打开的网址中，账号登录的输入框，输入字符串"用户名"
    username = input('请输入你的用户名：')
    password = input('请输入你的密码：')
    print('登录中......')
    driver.find_element_by_id('username').send_keys(username)
    driver.find_element_by_id('password').send_keys(password)
    # id="submit"是点击登录， click() 是模拟点击
    driver.find_element_by_id("submit").click()
    time.sleep(2)
    print('登录成功\n')

python 复制代码

# 点击 风险分级管控
    driver.implicitly_wait(5)
    risk_grade_control = driver.find_element_by_link_text("风险分级管控")
    risk_grade_control.click()
    time.sleep(2)
    print('已点击【风险分级管】\n')

python 复制代码

# 点击 风险点隐患上报
    driver.implicitly_wait(5)
    xpth = driver.find_element_by_xpath("//div[@data-tid='e9c7735c77284173a243f8e47999ee8d']")
    xpth.click()
    time.sleep(2)
    print('已点击【风险点隐患上报】\n')

注意：可能点击 "风险点隐患上报" 右边页面是异步加载的找不到对应的文本按钮

python 复制代码

    # 重定向页面，确保操作的是当前窗口页面内容
    driver.switch_to.default_content()
    frame = driver.find_elements_by_tag_name('iframe')[0]
    driver.switch_to.frame(frame)
    time.sleep(1)
