Which content-type(MIME type) to use for JSON data

Problem :

Your program sitting in your web server is pumping out JSON data. You need to set the correct header Content-Type or MIME type.

Which content-type should you use?

Solution :

For JSON:

Content-Type: application/json

Example data :

{ "Id": 1, "Name": "Boo", "Job": "CEO" }

For JSON-P and for passing a JavaScript object literal :

Content-Type: application/javascript

Example data :

functionCall({ "Id": 1, "Name": "Boo", "Job": "CEO" });

To set Header example in Golang :

w.Header().Set("Content-Type", "application/json")

w.Header().Set("Content-Type", "application/javascript")
