json - 什么是正确的JSON内容类型？(What is the correct JSON content type?)

Question

I've been messing around with JSON for some time, just pushing it out as text and it hasn't hurt anybody (that I know of), but I'd like to start doing things properly.

(我一直在弄乱JSON一段时间，只是将其作为文本推出，并没有伤害任何人（据我所知），但是我想正确地做事。)

I have seen so many purported "standards" for the JSON content type:

application/json
application/x-javascript
text/javascript
text/x-javascript
text/x-json

But which one is correct, or best?

I gather that there are security and browser support issues varying between them.

I know there's a similar question, What MIME type if JSON is being returned by a REST API?

(我知道有一个类似的问题， 如果REST API返回JSON，则为哪种MIME类型？)
