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() {
r := gin.Default()
r.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
r.Run(":8080")
}
