这篇文章主要介绍了Python django框架输入汉字，数字，字符转成二维码实现详解,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

模块必备：Python环境 + pillow + qrcode 模块

核心代码<br>import qrcode qr = qrcode.QRCode(      version=2,      error_correction=qrcode.constants.ERROR_CORRECT_L,      box_size=20,      border=4,    )qr.add_data('你要生成的文件')qr.make(fit=True)img = qr.make_image()# 只需要改成自己的路径img.save('text.png')　　<br># img.save('/Users/admin/PycharmProjects/str_code/statics/assets/png/'+'text.png'）

django views函数代码！路由自己设置就可以。

from django.shortcuts import render # Create your views here.  import qrcode# python-qrcode是个用来生成二维码图片的第三方模块，依赖于 PIL 模块和 qrcode 库。  def str_decode_code(request):  print(request.method)  if request.method == 'GET':    return render(request,'index.html')  if request.method== 'POST':    text = request.POST.get('message')    print(text)     qr = qrcode.QRCode(      version=2,      error_correction=qrcode.constants.ERROR_CORRECT_L,      box_size=20,      border=4,    )    qr.add_data(text)    qr.make(fit=True)    img = qr.make_image()    # 只需要改成自己的路径    img.save('/Users/admin/PycharmProjects/str_code/statics/assets/png/'+'text.png')    return render(request,'en_index.html',{'mgs':text})

这样就可以动态生成二维码了。
