这篇文章给大家分享的是有关Python中django框架输入汉字，数字，字符生成二维码的示例分析的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
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}) 前段代码
