Echo advocates centralized HTTP error handling by returning error from middleware or handlers.
- Log errors from a unified location
- Send customized HTTP responses
For example, when basic auth middleware finds invalid credentials it returns
401 - Unauthorized
error, aborting the current HTTP request.
package main
import (
"net/http"
"github.com/labstack/echo"
)
func main() {
e := echo.New()
e.Use(func(next echo.HandlerFunc) echo.HandlerFunc {
return func(c echo.Context) error {
// Extract the credentials from HTTP request header and perform a security
// check
// For invalid credentials
return echo.NewHTTPError(http.StatusUnauthorized)
// For valid credentials call next
// return next(c)
}
})
e.GET("/", welcome)
e.Logger.Fatal(e.Start(":1323"))
}
func welcome(c echo.Context) error {
return c.String(http.StatusOK, "Welcome!")
}
