基于Python实现IP摄像头访问的用户输入键值提取脚本开发问询

Here's a practical, easy-to-use script that does exactly what you need—takes a vehicle identifier, handles port input (or auto-maps if you predefine pairs), and opens the camera feed in your default browser.

Basic Version (Manual Port Input) #

This version prompts for both the vehicle ID and port, with basic validation to avoid invalid inputs breaking the flow:

import webbrowser

def launch_camera_feed():
    # Get vehicle identifier from user
    vehicle_id = input("Enter the vehicle identifier (e.g., truck22): ").strip()
    if not vehicle_id:
        print("Error: Vehicle identifier can't be empty!")
        return

    # Get and validate port number
    while True:
        port_input = input(f"Enter the port for {vehicle_id}: ").strip()
        if port_input.isdigit():
            port = int(port_input)
            if 1 <= port <= 65535:
                break
            else:
                print("Error: Port must be between 1 and 65535.")
        else:
            print("Error: Please enter a valid numeric port.")

    # Replace with your EC2 instance's public IP
    ec2_public_ip = "YOUR_EC2_PUBLIC_IP"
    camera_url = f"http://{ec2_public_ip}:{port}"

    # Open the URL in default browser
    print(f"Launching camera feed for {vehicle_id} at {camera_url}...")
    webbrowser.open(camera_url)

if __name__ == "__main__":
    launch_camera_feed()

Pro Version (Predefined Vehicle-Port Mapping) #

Since you have hundreds of cameras, manually entering ports every time will get tedious. This version uses a pre-configured dictionary to map vehicle IDs directly to ports—no more port typing:

import webbrowser

# Predefine your vehicle-port mappings here
CAMERA_PORT_MAP = {
    "truck22": 8001,
    "van15": 8002,
    "bus07": 8003,
    # Add all your vehicle-port pairs here
}

def launch_camera_feed():
    vehicle_id = input("Enter the vehicle identifier (e.g., truck22): ").strip()
    
    if vehicle_id not in CAMERA_PORT_MAP:
        print(f"Error: No port found for vehicle {vehicle_id}. Check your input or update the mapping.")
        return

    port = CAMERA_PORT_MAP[vehicle_id]
    ec2_public_ip = "YOUR_EC2_PUBLIC_IP"
    camera_url = f"http://{ec2_public_ip}:{port}"

    print(f"Launching camera feed for {vehicle_id} at {camera_url}...")
    webbrowser.open(camera_url)

if __name__ == "__main__":
    launch_camera_feed()

Quick Tips: #

• Replace YOUR_EC2_PUBLIC_IP with your actual EC2 instance's public IP (e.g., 1.2.3.4).
• The webbrowser module is part of Python's standard library—no extra packages to install.
• For the pro version, if maintaining a huge dictionary in code is messy, you can load the mapping from a CSV/JSON file instead. Just add a quick function to read the file and populate CAMERA_PORT_MAP.
