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

这样就可以动态生成二维码了。
