使用 selenium 启动 Chrome 浏览器

url = 'https://uland.taobao.com/sem/tbsearch?'

def get_driver(url):
    # 实例化一个启动参数对象
    options = webdriver.ChromeOptions()

    # 添加启动参数
    options.add_argument('--headless')  # *面模式

    # 禁用浏览器正在被自动化程序控制的提示
    # options.add_argument('--disable-infobars') # 新版已失效
    options.add_experimental_option("useAutomationExtension", False)  # 添加实验性质的设置参数
    options.add_experimental_option("excludeSwitches", ['enable-automation'])

    # 禁用图片加载
    prefs = {
        'profile.default_content_setting_values': {
            'images': 2
        }
    }

    options.add_experimental_option('prefs', prefs)

    driver = webdriver.Chrome(executable_path='./chromedriver.exe', options=options)
    driver.get(url)

    inputs = driver.find_element_by_id('J_search_key')
    inputs.send_keys('华为手机')

    search_btn = driver.find_element_by_css_selector('.submit')
    search_btn.click()
    return driver


driver = get_driver(url)

获取商品信息

def get_products(driver):
    items = driver.find_elements(By.XPATH, "//div//ul[@class='pc-search-items-list']/li")
    data = []
    for item in items:
        title = item.find_element_by_xpath(".//div/span[@class='title-text']").text
        price = item.find_element_by_xpath(".//div/span[@class='coupon-price-afterCoupon']").text
        store = item.find_element_by_xpath(".//div/div[@class='seller-name']").text
        sell = item.find_element_by_xpath(".//div/div[@class='sell-info']").text.split(' ')[-1]
        store_link = item.find_element_by_xpath("./a").get_attribute('href')
        data.append([title, price, store, sell, store_link])
    df = pd.DataFrame(data, columns=['title', 'price', 'store', 'sell', 'store_link'])
    save_df(df)

结果保存为csv

def save_df(df=None, path='./phone.csv'):
    if os.path.exists(path):
        df_exist = pd.read_csv(path, encoding='utf8', index_col=0)
        df = pd.concat([df_exist, df])
    df.to_csv(path, encoding='utf8')

获取下一页

def get_next_page(driver):
    driver.implicitly_wait(10)
    next_btn = driver.find_element_by_xpath(
        ".//span[@class='pc-search-page-item pc-search-page-item-after J_page-nav-item']")
    next_btn.click()

循环获取所有信息

def get_all_pages(driver, maxPage=4):
    try:
        current = int(unquote(driver.current_url).split('=')[-1])
    except:
        current = 0
    while current <= maxPage:
        get_products(driver)
        get_next_page(driver)
        driver.implicitly_wait(10)
        current = int(unquote(driver.current_url).split('=')[-1])

结果：
