下面的代码（几乎相同）在Linux下可以计算页面浏览量，但在Windows下可以将页面浏览量提高一倍。

有人能弄清楚为什么吗？

package main

import (
 "fmt"
    "http"
)

func main() {
    println("Running")
    http.HandleFunc("/", makeHomeHandler())
 http.ListenAndServe(":8080", nil)
}

// this version compiles and run OK under the Linux version of Golang
func makeHomeHandler() func(c *http.Conn, r *http.Request) {
    views := 1
    return func(c *http.Conn, r *http.Request) {
     fmt.Fprintf(c, "Counting %s, %d so far.", r.URL.Path[1:], views)
        views++
    }
}

/*
// this version compiles and run OK under the mingw version of Golang
// it uses a different argument type for the handler function,
// but the counter says "1 so far", then "3 so far", "5 so far", and so on.
func makeHomeHandler() func(c http.ResponseWriter, r *http.Request) {
    views := 1
    return func(c http.ResponseWriter, r *http.Request) {
     fmt.Fprintf(c, "Counting %s, %d so far.", r.URL.Path[1:], views)
        views++
    }
}
*/

在Mingw下：

http://localhost:8080/monkeys => Counting monkeys, 1 so far.
http://localhost:8080/monkeys => Counting monkeys, 3 so far.
http://localhost:8080/donkeys => Counting donkeys, 5 so far.

这可能是错误吗？

跟进：

实际上，如果我为另一个页面定义了其他处理程序，例如：

   http.HandleFunc("/test", testPageHandler)

Wich没有闭包，也没有增加任何东西，计数器无论如何都会增加，但是只有+1：

因此，仍然在Mingw的领导下：

http://localhost:8080/monkeys => Counting monkeys, 1 so far.
http://localhost:8080/monkeys => Counting monkeys, 3 so far.
http://localhost:8080/test   => Another handler function that does not increment "views"
http://localhost:8080/donkeys => Counting donkeys, 6 so far.

在Linux下，输出如下所示：

http://localhost:8080/monkeys => Counting monkeys, 1 so far.
http://localhost:8080/monkeys => Counting monkeys, 2 so far.
http://localhost:8080/test   => Another handler function that does not increment "views"
http://localhost:8080/donkeys => Counting donkeys, 3 so far.
