JSONP

Using JSONP to request data from a server in a different domain. Add callback to response body if the query parameter callback exists.

func main() {
  router := gin.Default()

  router.GET("/JSONP?callback=x", func(c *gin.Context) {
    data := map[string]interface{}{
      "foo": "bar",
    }

    //callback is x
    // Will output  :   x({\"foo\":\"bar\"})
    c.JSONP(http.StatusOK, data)
  })

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