How can I modify the template to return only specific parts of the address?

You can modify the get_location function in the template to parse the Google Maps API response and return only specific parts of the address. Here's an example:

python @app.post("/get_location") async def get_location(latitude: str = Form(...), longitude: str = Form(...)): # ... existing code ... location_data = response.json() if location_data['status'] == 'OK': address_components = location_data['results'][0]['address_components'] formatted_address = location_data['results'][0]['formatted_address'] return { "formatted_address": formatted_address, "street_number": next((component['long_name'] for component in address_components if 'street_number' in component['types']), None), "route": next((component['long_name'] for component in address_components if 'route' in component['types']), None), "locality": next((component['long_name'] for component in address_components if 'locality' in component['types']), None), "country": next((component['long_name'] for component in address_components if 'country' in component['types']), None) } else: raise HTTPException(status_code=400, detail="Unable to fetch location data")

This modification will return a structured object with specific address components.

How can I add error handling for invalid coordinates in the Google Reverse Geolocation template?

You can add input validation and error handling for invalid coordinates by modifying the get_location function. Here's an example:

```python from fastapi import FastAPI, Form, HTTPException from pydantic import BaseModel, validator from typing import Optional

class Coordinates(BaseModel): latitude: float longitude: float

   @validator('latitude')
   def validate_latitude(cls, v):
       if v < -90 or v > 90:
           raise ValueError('Latitude must be between -90 and 90')
       return v

   @validator('longitude')
   def validate_longitude(cls, v):
       if v < -180 or v > 180:
           raise ValueError('Longitude must be between -180 and 180')
       return v

@app.post("/get_location") async def get_location(coords: Coordinates): try: # Use coords.latitude and coords.longitude in your API call url = f"https://maps.googleapis.com/maps/api/geocode/json?latlng={coords.latitude},{coords.longitude}&key={google_maps_api_key}" # ... rest of the function ... except ValueError as e: raise HTTPException(status_code=400, detail=str(e)) ```

This modification adds input validation for the latitude and longitude values, ensuring they are within valid ranges before making the API call.
