什麼是正確的JSON內容類型？

問題：

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. 我一直在弄亂JSON一段時間，只是將其做爲文本推出，並無傷害任何人（據我所知），可是我想正確地作事。

I have seen so many purported "standards" for the JSON content type: 我見過這麼多的所謂的「標準」爲JSON內容類型：

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

But which one is correct, or best? 可是哪個是正確的，仍是最好的？ I gather that there are security and browser support issues varying between them. 我發如今它們之間存在安全性和瀏覽器支持問題。

I know there's a similar question, What MIME type if JSON is being returned by a REST API? 我知道有一個相似的問題， 若是REST API返回JSON，則爲哪一種MIME類型？ , but I'd like a slightly more targeted answer. ，但我想要一個更有針對性的答案。
