I'd be happy to help you with that! ??Introduction
As a Python enthusiast, I'm excited to share with you a project that combines the power of web scraping and WeChat bot development. Today, we'll explore how to create a free version of a WeChat PC-end robot using "Ghost Hand" (鬼手) and a Python-based web scraper to real-time forward articles or news.
What is Ghost Hand?
Ghost Hand is an open-source project that provides a free version of the WeChat PC-end robot. It allows you to create a bot that can interact with users, send messages, and even perform tasks such as sending news articles or updates. The best part? It's completely free and open-source! ??Setting up Ghost Hand
To get started, you'll need to download the Ghost Hand source code from GitHub. Once you have it, follow these steps:
1. Extract the zip file to a directory of your choice.
2. Open the `config.json` file in a text editor and update the `appid` and `appsecret` values with your own WeChat app credentials.
3. Run the `ghost_hand.py` script using Python (e.g., `python ghost_hand.py`).
4. Follow the prompts to set up your bot's name, description, and other settings.
Creating a Web Scraper
Now that we have our Ghost Hand bot set up, let's create a web scraper to fetch news articles in real-time. We'll use Python's `requests` and `BeautifulSoup` libraries for this task.
Here's an example code snippet:
```pythonimport requestsfrom bs4 import BeautifulSoup Define the URL of the news article you want to scrapeurl = " Send a GET request to the URLresponse = requests.get(url)
Parse the HTML content using BeautifulSoupsoup = BeautifulSoup(response.content, 'html.parser')
Extract the article title and texttitle = soup.find('h1', {'class': 'article-title'}).text.strip()
text = soup.find('div', {'class': 'article-text'}).text.strip()
Send the article to your WeChat bot using Ghost Hand's APIghost_hand_api.send_message(title + '
' + text)
```
Integrating the Web Scraper with Ghost Hand
To integrate our web scraper with Ghost Hand, we'll need to modify the `ghost_hand.py` script to call our web scraper function whenever a new message is received.
Here's an updated code snippet:
```pythonimport ghost_hand Define your WeChat app credentials and bot settingsappid = 'your_app_id'
appsecret = 'your_app_secret'
bot_name = 'Your Bot Name'
Create a Ghost Hand instance with the specified app credentials and bot settingsghost_hand_instance = ghost_hand.GhostHand(appid, appsecret, bot_name)
Define your web scraper functiondef scrape_news():
Call the web scraper code snippet we defined earlier title, text = scrape_article()
return title + '
' + text Set up a message handler to call our web scraper function whenever a new message is receivedghost_hand_instance.on_message += lambda msg: ghost_hand_api.send_message(scrape_news())
```
Conclusion
In this tutorial, we've explored how to create a free version of a WeChat PC-end robot using Ghost Hand and a Python-based web scraper. By integrating our web scraper with Ghost Hand's API, we can real-time forward news articles or updates to users. This project demonstrates the power of combining natural language processing (NLP) and machine learning (ML) techniques with web scraping and bot development.
