Changing default header for JSON data in Gin

I've noticed that using Gin to return a response like this:

c.JSON(http.StatusOK, jsonData)

automatically creates the following header:

application/json; charset=utf-8

Is it possible to modify the header somehow to just return

application/json

I'd rather take this approach than splitting the string at the ;

1. Modify the source code to remove the ; charset=utf-8 string, or

2. Have a wrapper function which manually sets Content-Type before the gin.Context.JSON call:

    func JSON(c *gin.Context, code int, obj interface{}) {
        c.Header("Content-Type", "application/json")
        c.JSON(code, obj)
    }
   
    // ...
   
    JSON(c, http.StatusOK, jsonData)
   

You can add new headers in the request like this :

c.Request.Header.Add("x-request-id", requestID)
