How can I modify the FastAPI OpenGraph Endpoint Viewer to include additional OpenGraph properties?

To include additional OpenGraph properties, you can modify the OpenGraphData model and the fetch_opengraph function. Here's an example of how to add the og:type property:

```python class OpenGraphData(BaseModel): url: HttpUrl title: str = None description: str = None image: HttpUrl = None og_type: str = None # Add this line

@app.post("/opengraph", response_class=HTMLResponse) async def fetch_opengraph(url: str): # ... existing code ... og_data.og_type = soup.find("meta", property="og:type")["content"] if soup.find("meta", property="og:type") else None # ... rest of the function ...

   # Don't forget to update the HTML template to display the new property

```

How can I implement error handling for invalid URLs in the FastAPI OpenGraph Endpoint Viewer?

You can implement error handling for invalid URLs by adding a try-except block in the fetch_opengraph function. Here's an example:

```python from fastapi import HTTPException import validators

@app.post("/opengraph", response_class=HTMLResponse) async def fetch_opengraph(url: str): if not validators.url(url): raise HTTPException(status_code=400, detail="Invalid URL format")

   try:
       response = requests.get(url, timeout=5)
       response.raise_for_status()
       # ... rest of the function ...
   except requests.exceptions.RequestException as e:
       logger.error(f"Error fetching URL: {str(e)}")
       raise HTTPException(status_code=400, detail=f"Error fetching URL: {str(e)}")

```

This modification adds URL validation and handles network-related errors, improving the robustness of the FastAPI OpenGraph Endpoint Viewer.

A tool for viewing FastAPI endpoints with OpenGraph metadata. If you see this on twitter, please improve and publish templates

Here's a step-by-step guide for using the FastAPI OpenGraph Endpoint Viewer template:

Introduction

The FastAPI OpenGraph Endpoint Viewer is a powerful tool that allows you to fetch and display OpenGraph metadata from any given URL. This template provides a simple web interface where users can input a URL and view the associated OpenGraph data, including title, description, and image.

Getting Started

  1. Click "Start with this Template" to begin using the FastAPI OpenGraph Endpoint Viewer in your Lazy project.

Test the Application

  1. Press the "Test" button to deploy and run the application. This will launch the Lazy CLI and start the FastAPI server.

  2. Once the deployment is complete, Lazy will provide you with two important links:

  3. The main application URL
  4. The FastAPI documentation URL (usually ending with /docs)

Using the Application

  1. Open the main application URL in your web browser. You'll see a simple interface with a form to enter a URL.

  2. Enter a valid URL into the input field and click "Fetch OpenGraph Data".

  3. The application will fetch the OpenGraph data for the provided URL and display it on the page, including:

  4. Title
  5. Description

  6. Image (if available)

  7. To try another URL, click the "Try another URL" link at the bottom of the results page.

Exploring the API

  1. If you want to interact with the API directly or explore its capabilities, open the FastAPI documentation URL provided by Lazy.

  2. In the documentation, you'll find two endpoints:

  3. GET /opengraph: Returns the HTML form for entering URLs

  4. POST /opengraph: Accepts a URL and returns the OpenGraph data

  5. You can test the POST endpoint directly from the FastAPI documentation page by clicking on the endpoint, then "Try it out", entering a URL, and clicking "Execute".

Integrating the App

This application can be used as a standalone tool or integrated into other projects that require OpenGraph data fetching. Here's a sample Python code snippet to demonstrate how you might use this API in another application:

```python import requests

api_url = "YOUR_LAZY_APP_URL/opengraph" target_url = "https://example.com"

response = requests.post(api_url, data={"url": target_url})

if response.status_code == 200: print("OpenGraph data:", response.text) else: print("Error fetching OpenGraph data") ```

Replace YOUR_LAZY_APP_URL with the actual URL provided by Lazy for your deployed application.

By following these steps, you'll have a fully functional OpenGraph data viewer and API running on the Lazy platform, ready to fetch and display metadata for any URL you provide.
