the http handler executed twice?! #1298
Description
by shawn.hek:
i just write a simple program as follow:
import (
"http"
"fmt"
)
var counter int;
func handler(w http.ResponseWriter, r *http.Request) {
counter++
fmt.Printf("%d\n", counter)
}
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":12345", nil)
}
but the console output confused me--every time i open the url in the browser, it outputs
twice like
0
1 // 1st
2
3 // 2nd
and so on
