Django：使用render或render_to_response时添加响应头 [英] Django: Add response header when using render or render_to_response

问题描述

如何将响应标头添加到Django响应中？我有：

How do I add a response header to a Django response? I have:

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

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

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

推荐答案

分配的结果将 c 渲染为变量，设置标头，然后返回响应。

Assign the result of render to a variable, set the header, then return the response.

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

在大多数情况下，用户 render 比 render_to_response 。但是，如果您使用 render_to_response ，则可以使用相同的方法：

Most of the time, it is simpler to user render than render_to_response. However, if you are using render_to_response, the same approach will work:

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