利用 Python django 框架 输入汉字，数字，字符，等。。转成二维码！

　　模块必备：Python环境 + pillow  + qrcode 模块

　　

核心代码
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')　　
# 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。
