JSONP

Sends a JSON response with JSONP support. This method is identical to JSON, except that it opts-in to JSONP callback support. By default, the callback name is simply callback.

Override this by passing a named string in the method.

  1. func (c *Ctx) JSONP(data interface{}, callback ...string) error
  1. type SomeStruct struct {
  2.   name string
  3.   age  uint8
  4. }
  6. app.Get("/", func(c *fiber.Ctx) error {
  7.   // Create data struct:
  8.   data := SomeStruct{
  9.     name: "Grame",
  10.     age:  20,
  11.   }
  13.   return c.JSONP(data)
  14.   // => callback({"name": "Grame", "age": 20})
  16.   return c.JSONP(data, "customFunc")
  17.   // => customFunc({"name": "Grame", "age": 20})
  18. })
