Rich is a Python library for rich text and beautiful formatting in the terminal.

The Rich API makes it easy to add color and style to terminal output. Rich can also render pretty tables, progress bars, markdown, syntax highlighted source code, tracebacks, and more — out of the box.

pip install wifi-qrcode-generator

Python을 사용하여 Wi-Fi QR 코드를 생성하려면 qrcode 및 Pillow 라이브러리를 활용할 수 있습니다. Wi-Fi QR 코드의 데이터 형식은 다음과 같습니다:

import qrcode
from PIL import Image

def generate_wifi_qrcode(ssid, password, encryption="WPA", hidden=False, output_file="wifi_qrcode.png"):
    """
    Generates a Wi-Fi QR code and saves it as an image.
    
    :param ssid: The Wi-Fi network name (SSID)
    :param password: The Wi-Fi password
    :param encryption: Encryption type ('WPA', 'WEP', or 'nopass')
    :param hidden: Whether the network is hidden (True/False)
    :param output_file: Name of the output image file
    """
    # Format Wi-Fi QR code data
    wifi_data = f"WIFI:S:{ssid};T:{encryption};P:{password};H:{'true' if hidden else 'false'};;"
    
    # Generate QR code
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_L,
        box_size=10,
        border=4,
    )
    qr.add_data(wifi_data)
    qr.make(fit=True)

    # Create and save the QR code image
    img = qr.make_image(fill_color="black", back_color="white")
    img.save(output_file)
    print(f"Wi-Fi QR code saved as {output_file}")

    # Open and show the image
    img.show()

# Example usage
generate_wifi_qrcode(
    ssid="MyWiFiNetwork",
    password="MySecurePassword",
    encryption="WPA",  # WPA/WEP/nopass
    hidden=False,       # Hidden network? True/False
    output_file="wifi_qrcode.png"
)

코드 설명

1. Wi-Fi QR 코드 형식:
   • WIFI:S:<SSID>;T:<WPA/WEP/nopass>;P:<Password>;H:<Hidden (true/false)>;;
     • S: Wi-Fi 이름 (SSID)
     • T: 암호화 방식 (WPA, WEP, nopass)
     • P: 비밀번호
     • H: 네트워크 숨김 여부 (true 또는 false)
2. QR 코드 생성:
   • **qrcode.QRCode**를 사용하여 데이터를 추가하고 이미지를 생성.
   • QR 코드는 기본적으로 검은색 fill_color와 흰색 back_color를 사용하여 생성.
3. 결과 저장 및 표시:
   • 생성된 QR 코드를 wifi_qrcode.png로 저장.
   • **img.show()**를 사용하여 시스템 기본 이미지 뷰어에서 표시.

결과

• wifi_qrcode.png 파일이 생성됩니다.
• QR 코드를 스캔하면 자동으로 Wi-Fi 네트워크에 연결할 수 있습니다.
