Django：使用render或render_to_response时添加响应头

Question

如何为Django响应添加响应头？我有：

response = HttpResponse()
response['Cache-Control'] = 'no-cache'

return render(request, "template.html", {}) 

# Alternately using render_to_response
# return render_to_response("template.html", {})

Answer 1

将render的结果分配给变量，设置标题，然后返回响应。

response = render(request, "template.html", {})
response['Cache-Control'] = 'no-cache'
return response

大多数情况下，用户render比render_to_response更简单。但是，如果您使用render_to_response，则相同的方法将起作用：

response = render_to_response("template.html", {})
response['Cache-Control'] = 'no-cache'
return response
