Content-Type...charset=X 和 Content-Encoding=X 有什么区别? [英] What is the difference between Content-Type...charset=X and Content-Encoding=X?

问题描述

两者之间有什么有效的区别

Is there any effective difference between

Content-Encoding: UTF-8
Content-Type: text/html; charset=utf-8

?

推荐答案

可选参数 charset 仅对基于文本的内容有意义(Content-Types 像 text/plain、text/html 等).并非所有消息都是文本.

Optional parameter charset makes sense only for text-based content (Content-Types like text/plain, text/html, and such). Not all messages are text.

Content-Encoding 表示整个正文已经以某种方式编码(通常是压缩的).此标头的典型值为 gzip 和 deflate.此消息的收件人应解码(例如 ungzip)正文以获取原始消息.

Content-Encoding means that the whole body has been encoded in some way (usually compressed). Typical values for this header are gzip and deflate. The recipient of this message should decode (e.g. ungzip) the body to get the original message.

我什至不确定 UTF-8 作为 Content-Encoding 的值是否有意义.

I'm not even sure if UTF-8 makes any sense as a value for the Content-Encoding.
