Automated Timed Purchase Script for Taobao Using Python and Selenium

The author describes a personal motivation: during a Double‑11 flash sale, his girlfriend missed the discount because she was slow, so he decided to write an automated timed‑purchase script.

Step 1

The script will launch a browser, go to Taobao, stay in the shopping cart, and wait for the purchase time to automatically buy and pay.

Step 2

Import the required modules: a datetime module for the target time and Selenium for browser automation.

<code>import datetime  # module</code>
<code>now = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f')</code>
<code>import time</code>
<code># Full‑automation Python code</code>
<code>from selenium import webdriver</code>

Step 3

Open Google Chrome and navigate to www.taobao.com , then click the login button to reach the shopping cart.

Code:

<code>times = "2021-11-04 21:00:00.00000000"</code>
<code>browser = webdriver.Chrome()</code>
<code>browser.get("https://www.taobao.com")</code>
<code>time.sleep(3)  # click</code>
<code>browser.find_element_by_link_text("亲，请登录").click()</code>

Because storing account credentials in the script is insecure, the author uses manual QR‑code login.

<code>print(f"请尽快扫码登录")</code>
<code>time.sleep(10)</code>
<code>browser.get("https://cart.taobao.com/cart.htm")</code>
<code>time.sleep(3)</code>

Step 4

After entering the cart, the script waits for the flash‑sale time, selects all items, and proceeds to checkout.

<code># Select all items in the cart</code>
<code>while True:</code>
<code>    try:</code>
<code>        if browser.find_element_by_id("J_SelectAll1"):</code>
<code>            browser.find_element_by_id("J_SelectAll1").click()</code>
<code>            break</code>
<code>    except:</code>
<code>        print(f"找不到购买按钮")</code>

<code># Get current time and compare with target</code>
<code>now = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f')</code>
<code>print(now)</code>
<code>if now > times:</code>
<code>    # Click the checkout button</code>
<code>    while True:</code>
<code>        try:</code>
<code>            if browser.find_element_by_link_text("结 算"):</code>
<code>                print("here")</code>
<code>                browser.find_element_by_link_text("结 算").click()</code>
<code>                print(f"主人,程序锁定商品,结算成功")</code>
<code>                break</code>
<code>        except:</code>
<code>            pass</code>

<code>    # Click the submit order button</code>
<code>    while True:</code>
<code>        try:</code>
<code>            if browser.find_element_by_link_text('提交订单'):</code>
<code>                browser.find_element_by_link_text('提交订单').click()</code>
<code>                print(f"抢购成功，请尽快付款")</code>
<code>        except:</code>
<code>            print(f"主人,我已帮你抢到商品啦,您来支付吧")</code>
<code>            break</code>
<code>        time.sleep(0.01)</code>

The script assumes the desired items are already in the cart; when the specified time arrives, it selects all, proceeds through checkout, and attempts to submit the order.
