使用第三方庫qrcode或者MyQr給自己的博客網(wǎng)址快速生成二維碼，一鍵分享，文中含有詳細示例代碼，有需要的朋友可以借鑒參考下，希望能夠有所幫助

前期準備

qrcode

下載地址：

qrcode · PyPI

QR Code image generator

https://pypi.org/project/qrcode/

使用簡介：

import qrcode
qr = qrcode.QRCode(
    version=5,
    error_correction=qrcode.constants.ERROR_CORRECT_L,
    box_size=10,
    border=4,
)
qr.add_data('https://blog.csdn.net/boysoft2002/article/details/120213715')
qr.make(fit=True)
img = qr.make_image(fill_color="black", back_color="white")

MyQR

下載地址：

MyQR · PyPI

https://pypi.org/project/MyQR/

使用簡介：

from MyQR import myqr
myqr.run(words = 'https://blog.csdn.net/boysoft2002/article/details/120257133',
         save_name = 'qrcode.jpg'
         ) 
#生成帶背景圖片的二維碼
myqr.run(words = 'https://blog.csdn.net/boysoft2002/article/details/120242318',
         picture = r'background.jpg',  #支持動態(tài)gif作背景
         colorized = True,　# True：彩色，F(xiàn)alse：黑白
         save_name = 'qrcode.png'
         )

安裝第三方庫

如下二選一安裝都可以，若存在其它依賴庫請一并安裝：

D:\>pip install qrcode

代碼

以qrcode為例，快速生成博客的二維碼（粘貼自己的網(wǎng)址到urls變量中，文章標題非必須項）。
