PureJSON

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() {
  router := gin.Default()

  // Serves unicode entities
  router.GET("/json", func(c *gin.Context) {
    c.JSON(200, gin.H{
      "html": "<b>Hello, world!</b>",
    })
  })

  // Serves literal characters
  router.GET("/purejson", func(c *gin.Context) {
    c.PureJSON(200, gin.H{
      "html": "<b>Hello, world!</b>",
    })
  })

  // listen and serve on 0.0.0.0:8080
  router.Run(":8080")
}
