Q: **How to retrieve `*http.Request` and `http.ResponseWriter` from `echo.Context`?**
|
|
|
|
- `http.Request` > `c.Request().(*standard.Request).Request`
|
|
- `http.ResponseWriter` > `c.Response()`
|
|
|
|
> Standard engine only

|
io.WriteString(w, "Handler!")
|
|
}
|
|
|
|
func main() {
|
|
e := echo.New()
|
|
e.GET("/", standard.WrapHandler(http.HandlerFunc(handler)))
|
|
e.Run(standard.New(":1323"))
|
|
}

|
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {

println("Middleware!")
|
|
h.ServeHTTP(w, r)
|
|
})
|
|
}
|
|
|
|
func main() {
|
|
e := echo.New()

e.Use(standard.WrapMiddleware(middleware))
|
|
e.GET("/", func(c echo.Context) error {
|
|
return c.String(http.StatusOK, "OK")
