Normally, JSON replaces special HTML characters with their unicode entities, e.g. < becomes \u003c. If you want to encode such characters literally, you can use PureJSON instead. This feature is unavailable in Go 1.6 and lower.

func main() {
	r := gin.Default()
	// Serves unicode entities
	r.GET("/json", func(c *gin.Context) {
		c.JSON(200, gin.H{
			"html": "<b>Hello, world!</b>",
	// Serves literal characters
	r.GET("/purejson", func(c *gin.Context) {
		c.PureJSON(200, gin.H{
			"html": "<b>Hello, world!</b>",
	// listen and serve on
