Web Article Summarization using Dify API

Overview

This project implements a web article summarization tool using the Dify API. Given a URL, the script fetches the content and summarizes it automatically. The API request is made using Python's requests library.

Features

• Sends a URL to the Dify API for summarization.
• Retrieves and displays the summarized content.
• Uses API authentication via an API key.
• Supports blocking and streaming response modes.

Prerequisites

Ensure you have the following installed:

• Python 3.8+
• requests library

Install Dependencies

pip install requests

Usage

1. Set Up API Key and Endpoint

Modify the script with your Dify API key and the URL you want to summarize:

url = "https://api.dify.ai/v1/workflows/run"
api_key = "your_api_key"  # Replace with your API Key

2. Run the Script

Execute the script to send a request and receive a summary:

python summarize.py

3. Expected Output

Upon successful execution, the script will return the summarized content:

成功取得摘要:
<summary_text>

If the request fails, the script will output the error message and HTTP status code.

Code Explanation

API Request Configuration

The script sets up an HTTP POST request to the Dify API with authentication headers:

headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json"
}

Sending the Request

The script sends the URL to the API for processing:

payload = {
    "inputs": {"url": url_to_summarize},
    "response_mode": "blocking",
    "user": "unique_user_id"
}
response = requests.post(url, headers=headers, json=payload)

Handling the Response

If successful, the summarized text is extracted and printed:

if response.status_code == 200:
    result = response.json()
    summary = result['data']['outputs']
    print("成功取得摘要:", summary)
else:
    print(f"請求失敗，狀態碼: {response.status_code}，訊息: {response.text}")

Notes

• Ensure you replace your_api_key with a valid Dify API key.
• The API supports different response modes (blocking or streaming). Adjust response_mode as needed.
• If summarization fails, verify that the provided URL is accessible and contains valid content.
