A step-by-step guide on how to obtain 1688 product details

In today's Internet age, the ways and amounts of information available have exploded. Among them, product details, as an important source of information, are a necessary task for many people. As a well-known B2B platform in China, 1688 has a large amount of product information. This article will teach you how to obtain 1688 product details through simple steps.

1. Understand web page structure and data extraction

Before we begin, we first need to understand the page structure of the 1688 website. Product details on the 1688 website are usually organized in one or more HTML tags. We need to find the HTML tag that contains the product details and extract the required information from it.

2. Use Python crawler

In order to get product details, we need to use a programming language to automate the process. Python is a very beginner-friendly language, and there are many libraries to help you implement crawler functions.

3. Install the necessary libraries

In Python, you can use ​requests​the library to send HTTP requests and get web page content, and ​BeautifulSoup​the library to parse HTML and extract the required information. Both libraries can be installed with the following commands:

pip install requests beautifulsoup4

4. Write Python code

Now, you can start writing Python code to get product details. Here's a simple example:

import requests
from bs4 import BeautifulSoup

# 要爬取的商品URL
url = 'https://www.1688.com/product/544904595.html'

# 发送HTTP请求，获取网页内容
response = requests.get(url)

# 使用BeautifulSoup解析网页内容
soup = BeautifulSoup(response.text, 'html.parser')

# 找到要爬取的商品详情信息所在的HTML标签
product_info = soup.find('div', {'class': 'pro-desc'})

# 输出商品详情信息
print(product_info.text)

In this example, we first send an HTTP request to the specified URL to obtain the content of the web page. Then, we use BeautifulSoup to parse the HTML code of the web page and find the HTML tags containing product details. Finally, we output the text content in this tag.

5. Running code and debugging

Save the above code as a Python file (for example ​get_1688_product.py​) and run it in the terminal or command line:

python get_1688_product.py

After running, you will see the product details being output to the console. If you encounter a bug or problem, you can use debugging to resolve the issue. Make sure you have correctly installed the required libraries and have set the URL and other necessary parameters correctly. If the structure of the web page changes, the code may need to be adjusted to accommodate the new structure.

6. Precautions and Code of Ethics

When writing and using crawlers, be sure to comply with the following ethical guidelines and legal regulations:

1. Respect the website’s access restrictions and privacy policies. Do not access frequently or crawl too much data to avoid affecting the normal operation of the website.
2. Do not use crawlers to obtain sensitive personal information or trade secrets. Respect the privacy and intellectual property rights of others.
3. If the structure of your site changes, please update your code to adapt to the new structure. Don't use outdated or broken code to get data.
