Question

这是我的网址

url(r'download/$', views.DownloadView.serve_pdf, name="pdfdata-ddl" )

这是我的观点

class DownloadView():

    def serve_pdf(request):
        #pdf_data = magically_create_pdf()

        response = HttpResponse(mimetype='application/pdf')
        response['Content-Disposition'] = 'attachment; filename="/test/angular.pdf"'
        return response

错误就是这个

unbound method serve_pdf() must be called with DownloadView instance as first argument (got WSGIRequest instance instead)

Answer 1

您需要传入self作为方法的第一个参数：

class DownloadView(object):
    def serve_pdf(self, request):
        #pdf_data = magically_create_pdf()

        response = HttpResponse(mimetype='application/pdf')
        response['Content-Disposition'] = 'attachment; filename="/test/angular.pdf"'
        return response

[编辑] 抱歉，我忘了提及你还需要在URL定义中实例化该类：

url(r'download/$', views.DownloadView().serve_pdf, name="pdfdata-ddl" )

要使用Python创建PDF，请查看Pisa。
