def download_file(request):   
    
    # Text file  
    #response = HttpResponse(mimetype='text/plain')   #定义输出格式为txt                                
    #response['Content-Disposition'] = 'attachment; filename=my.txt'   #规定文件名字 
　　
　　
    #给txt写入内容           
    #response.write("aa/n")  
    #response.write("bb")   
     
    # PDF file

    from reportlab.pdfgen import canvas     
    response = HttpResponse(mimetype='application/pdf')  
    response['Content-Disposition'] = 'attachment; filename=somefilename.pdf'  
    p = canvas.Canvas(response)  
    p.drawString(100, 100, "Hello world.")  
    p.showPage()  
    p.save()  
            
    return response
