Go HTTP 服务器最小示例

minimal_go_http_server.txt

package main

import (
    "fmt"
    "log"
    "net/http"
)

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello world!")
    })

    // log.Fatal 显示类似以下错误
    //  端口已被使用
    log.Fatal(http.ListenAndServe(":8080", nil))
}

package main

import (
    "fmt"
    "log"
    "net/http"
)

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello world!")
    })

    // log.Fatal 显示类似以下错误
    //  端口已被使用
    log.Fatal(http.ListenAndServe(":8080", nil))
}

将此文件保存为 Main.go，放在名为 GoHTTPServer 的目录中，运行 go build && ./GoHTTPServer。然后，在浏览器中打开 http://localhost:8080 自行查看结果。
