推荐答案

简单：你没有。



这些标头是HTTP语法的一部分。如果你删除它们，你的回复将不再有效。



超文本传输​​协议 - 维基百科 [ ^ ]

HTTP标题字段列表 - 维基百科 [ ^ ]



您可以更改 Cache-Control ， Expires 和 Pragma 通过设置 CacheControl [ ^ ]属性回复。



响应格式化程序将设置 Content-Type 和 Content-Length 标头。它们无法更改或删除，因为这会破坏响应。



日期会自动设置，并且无法更改或删除。

Simple: You don't.

Those headers are part of the HTTP grammar. If you removed them, your response would no longer be valid.

Hypertext Transfer Protocol - Wikipedia[^]
List of HTTP header fields - Wikipedia[^]

You can change the Cache-Control, Expires and Pragma headers by setting the CacheControl[^] property on the response.

The Content-Type and Content-Length headers will be set by the response formatter. They cannot be changed or removed, since that would break the response.

The Date is set automatically, and cannot be changed or removed.
