Handler path
Context.Path()
returns the registered path for a handler, it can be used in the middleware for logging purpose.
Example
e.Use(func(c *echo.Context) error {
println(c.Path()) // Prints `/users/:name`
return nil
})
e.Get("/users/:name", func(c *echo.Context) error) {
return c.String(http.StatusOK, name)
})
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
