Python 405在Django3中生成pdf时出错

我按照本教程生成PDF，效果很好

问题是，当我使用post请求生成pdf时，它会显示405错误。我正在使用post方法访问客户id以生成发票

这是我的GeneratePDF课程

class GeneratePDF(View):
    def get(self, request, *args, **kwargs):
        
            if request.method == 'POST':
                template = get_template('head/invoice.html')
                context = {
                "customer":"aaaa"
                }
                html = template.render(context)
                pdf = render_to_pdf('head/invoice.html', context)
                if pdf:
                    response = HttpResponse(pdf, content_type='application/pdf')
                    filename = "Invoice_%s.pdf" %("12341231")
                    content = "inline; filename='%s'" %(filename)
                    download = request.GET.get("download")
                if download:
                    content = "attachment; filename='%s'" %(filename)
                response['Content-Disposition'] = content
                return response
            
            template = get_template('head/invoice.html')
            context = {
                "customer":"aaaa"
            }
            html = template.render(context)
            pdf = render_to_pdf('head/invoice.html', context)
            if pdf:
                response = HttpResponse(pdf, content_type='application/pdf')
                filename = "Invoice_%s.pdf" %("12341231")
                content = "inline; filename='%s'" %(filename)
                download = request.GET.get("download")
                if download:
                    content = "attachment; filename='%s'" %(filename)
                response['Content-Disposition'] = content
                return response

我没有编辑任何其他文件

这是来自服务器的响应

Method Not Allowed (POST): /employee/customer_printbill/
Method Not Allowed: /employee/customer_printbill/

我是django的初学者，我无法解决这个问题。请帮帮我。

您正在混合基于函数和基于类的视图。您应该在基于类的视图中定义

post

方法，请求将被分派到该

post

方法。因此，您不需要在

get

方法中检查

request.method

是否为

POST

，因为

POST

请求将由

POST

方法处理。有关更多信息，请参阅。

谢谢您让我知道这一点。在get方法上检查request.method，我真傻
