Load Balancer example from quickstart keeps getting 404 not found #61

Quantisan · 2014-08-03T16:28:54Z

I'm trying the load balancer example to reach https://www.google.com (i.e. single upstream node) from localhost. Such that when I do,

curl localhost:8000

It should return the page from Google. The problem is that I keep getting a 404 not found. Any idea please?

$ curl "http://localhost:8000/"

Here is my code.

    "time"

    "github.com/mailgun/vulcan/endpoint"

    "github.com/mailgun/vulcan/location/httploc"
    "github.com/mailgun/vulcan/route"
)

var PORT string = os.Getenv("PORT")
var smtpServers = []string{"https://www.google.com"}

func NewBalancer(servers []string) loadbalance.LoadBalancer {
    // Create a round robin load balancer with some endpoints
    rr, err := roundrobin.NewRoundRobin()
    if err != nil {
        log.Fatalf("Error: %s", err)
    }

    for _, s := range servers {
        rr.AddEndpoint(endpoint.MustParseUrl(s))
    }

    return rr
}

func main() {
    rr := NewBalancer(smtpServers)

    // Create a http location with the load balancer we've just added
    loc, err := httploc.NewLocation("loc1", rr)
    if err != nil {
        log.Fatalf("Error: %s", err)
    }

    // Create a proxy server that routes all requests to "loc1"
    proxy, err := vulcan.NewProxy(&route.ConstRouter{Location: loc})
    if err != nil {
        log.Fatalf("Error: %s", err)
    }

    // Proxy acts as http handler:
    server := &http.Server{
        Addr:           ":" + PORT,
        Handler:        proxy,
        ReadTimeout:    10 * time.Second,
        WriteTimeout:   10 * time.Second,
        MaxHeaderBytes: 1 << 20,
    }
    log.Println("Listening on port " + PORT)
    server.ListenAndServe()
    if err != nil {
        log.Panic(err)
    }
