Format

Performs content-negotiation on the Accept HTTP header. It uses Accepts to select a proper format.

If the header is not specified or there is no proper format, text/plain is used. 

  1. func (c *Ctx) Format(body interface{}) error
  1. app.Get("/", func(c *fiber.Ctx) error {
  2.   // Accept: text/plain
  3.   c.Format("Hello, World!")
  4.   // => Hello, World!
  6.   // Accept: text/html
  7.   c.Format("Hello, World!")
  8.   // => <p>Hello, World!</p>
  10.   // Accept: application/json
  11.   c.Format("Hello, World!")
  12.   // => "Hello, World!"
  13.   // ..
  14. })
