django生成文件txt、pdf（在生成 PDF 文件之前，需要安装 ReportLab 库）

from django.http import HttpResponse

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  
    #在生成 PDF 文件之前，需要安装 ReportLab 库
    #http://code.djangoproject.com/svn/django/branches/0.95-bugfixes/docs/outputting_pdf.txt
    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
