Path parameter

Path parameter can be retrieved either by name Context.Param(name string) string or by index Context.P(i int) string. Getting parameter by index gives a slightly better performance.

Example

e.Get("/users/:name", func(c *echo.Context) error {
	// By name
	name := c.Param("name")

	// By index
	name := c.P(0)

	return c.String(http.StatusOK, name)
})

$ curl http://localhost:1323/users/joe

Query parameter

Query parameter can be retrieved by name using Context.Query(name string).

Example

e.Get("/users", func(c *echo.Context) error {
	name := c.Query("name")
	return c.String(http.StatusOK, name)
})

$ curl -G -d "name=joe" http://localhost:1323/users

Form parameter

Form parameter can be retrieved by name using Context.Form(name string).

Example

e.Post("/users", func(c *echo.Context) error {
	name := c.Form("name")
	return c.String(http.StatusOK, name)
})

$ curl -d "name=joe" http://localhost:1323/users
