Middleware
The middleware package contains functions that are used as middleware on the server side.
Getting Started
package main
import (
"fmt"
"net/http"
"github.com/gromey/proto-rest/logger"
"github.com/gromey/proto-rest/middleware"
)
func main() {
handlerFunc := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
if _, err := fmt.Fprintln(w, "Hello World!"); err != nil {
panic(err)
}
})
http.Handle("/example/", handlerFunc)
h := middleware.Sequencer(
http.DefaultServeMux,
middleware.DumpHttp(logger.LevelTrace),
middleware.Timer(logger.LevelInfo),
middleware.PanicCatcher,
)
if err := http.ListenAndServe(":8080", h); err != nil {
panic(err)
}
}

AllowCORS sets headers for CORS mechanism supports secure.
func DumpHttp ¶ added in v0.0.3
DumpHttp dumps the HTTP request and response, and prints out with logFunc.
func PanicCatcher ¶
PanicCatcher handles panics in http.HandlerFunc.
Types ¶
type CORSOptions ¶ added in v0.0.3
type CORSOptions struct {
AllowedOrigins []string // The origins that the server allows.
AllowMethods []string // List of methods that the server allows.
AllowHeaders []string // List of headers that the server allows.
MaxAge int // Tells the browser how long (in seconds) to cache the response to the preflight request.
AllowCredentials bool // Allow browsers to expose the response to the external JavaScript code.
}
