我在Django中使用ReportLab生成一些pdf.我跟着并试验了给this question的答案,并意识到其中的双引号没有意义:
response['Content-Disposition'] = 'inline; filename=constant_"%s_%s".pdf'\
% ('foo','bar')
给出文件名constant_-foo_bar-.pdf
response['Content-Disposition'] = 'inline; filename=constant_%s_%s.pdf' \
% ('foo','bar')
给出文件名constant_foo_bar.pdf
为什么是这样?它只是与文件系统的slug-esque sanitisation有关吗?
解决方法:
从this question的研究看来,它实际上是浏览器进行编码/转义.我用cURL
来确认Django本身没有逃脱这些标题.首先,我设置了一个最小的测试视图:
# views.py
def index(request):
response = render(request, 'template.html')
response['Content-Disposition'] = 'inline; filename=constant"a_b".html'
return response
然后跑了:

查看标题:filename =常量“a_b”.html.报价仍在那里!
