JSON使用哪种内容类型标头? " application/json; charset = utf-8"或"application/json"? [英] What content type header to use for JSON? "application/json; charset=utf-8 " or "application/json"?

问题描述

似乎JSON默认编码为UTF-8，Spring MVC默认返回application/json; charset=utf-8，这很难更改.

It seems that the JSON default encoding is UTF-8 and Spring MVC returns application/json; charset=utf-8 by default, which is hard to change.

推荐答案

根据 RFC 4627

JSON文本应以Unicode编码.默认编码为UTF-8.

JSON text SHALL be encoded in Unicode. The default encoding is UTF-8.

继续描述如何检测不同的UTF- *编码，这表明不支持其他编码.

It goes on to describe how the different UTF-* encoding are to be detecting, suggesting that no other encodings are supported.

此处的"SHALL"表示绝对要求(请参见 RFC 2119 ).

"SHALL" represents an absolute requirement here (see RFC 2119).

确实没有理由将非UTF编码与JSON一起使用(因为任何可以处理JSON的东西都可以绝对处理UTF-8).

And there really is no reason to use a non-UTF encoding with JSON (as anything that can handle JSON can definitely handle UTF-8).
