def create_qrcode(url, filename):  qr = qrcode.QRCode(    version=1,    #设置容错率为最高    error_correction=qrcode.ERROR_CORRECT_H,    box_size=10,    border=4,  )  qr.add_data(url)  qr.make(fit=True)   img = qr.make_image()  #设置二维码为彩色  img = img.convert("RGBA")  icon = Image.open('/Users/Jason/Desktop/qrcode/logo.png')  w, h = img.size  factor = 4  size_w = int(w / factor)  size_h = int(h / factor)  icon_w, icon_h = icon.size  if icon_w > size_w:    icon_w = size_w  if icon_h > size_h:    icon_h = size_h  icon = icon.resize((icon_w, icon_h), Image.ANTIALIAS)  w = int((w - icon_w) / 2)  h = int((h - icon_h) / 2)  icon = icon.convert("RGBA")  newimg = Image.new("RGBA", (icon_w + 8, icon_h + 8), (255, 255, 255))  img.paste(newimg, (w-4, h-4), newimg)   img.paste(icon, (w, h), icon)  img.save('/Users/Jason/Desktop/qrcode/' + filename + '.png', quality=100)
