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})

{#      function submsg(){#}

  </body>
 
</html>

这样就可以动态生成二维码了。
