监控服务器的注册及登陆并邮件通知的代码（go / python）

首先列出Go语言版的，通过这个小工具对比了下，go的开发效率与python差不多，稍比python多了些代码。

package main

import (
    "encoding/json"
    "fmt"
    "io/ioutil"
    "net/http"
    "net/smtp"
    "reflect"
    "strconv"
    "strings"
    "time"
)

//报警接收email
var emails = [...]string{"56219693@qq.com", "hartnett@foxmail.com"}

//--------------------------------------------------------------------------------
//邮件发送函数
func SendMail(user, password, host, to, subject, body, mailtype string) error {
    hp := strings.Split(host, ":")
    auth := smtp.PlainAuth("", user, password, hp[0])
    var content_type string
    if mailtype == "html" {
        content_type = "Content-Type: text/" + mailtype + "; charset=UTF-8"
    } else {
        content_type = "Content-Type: text/plain" + "; charset=UTF-8"
    }
    msg := []byte("To: " + to + "
From: " + user + "<" + user + ">
Subject: " + subject + "
" + content_type + "

" + body)
    fmt.Println(string(msg))
    send_to := strings.Split(to, ";")
    err := smtp.SendMail(host, auth, user, send_to, msg)
    return err
}

//--------------------------------------------------------------------------------
//用户注册检查
func Check_register(platform_url, username, password string) (err error, ret string) {
    url := fmt.Sprintf("http://%s/api/register/?username=%s&password=%s", platform_url, username, password)
    response, err := http.Get(url)
    defer response.Body.Close()
    body, _ := ioutil.ReadAll(response.Body)
    return err, string(body)
}

//--------------------------------------------------------------------------------
//用户登陆检查
func Check_login(platform_url, username, password, login_server string) (err error, ret string) {
    url := fmt.Sprintf("http://%s/api/login/?username=%s&password=%s&login_server=%s&port=5051", platform_url, username, password, login_server)
    response, err := http.Get(url)
    defer response.Body.Close()
    body, _ := ioutil.ReadAll(response.Body)
    return err, string(body)
}

//--------------------------------------------------------------------------------
//主函数
func main() {
    username := strconv.Itoa(int(time.Now().Unix()))
    password := username
    platform_url := "www.xxxgame.com"
    login_server := "123.123.123.123"

    mail_host := "smtp.qq.com:25"
    mail_user := "1234567890@qq.com"
    mail_pass := "1234567890"

    url := fmt.Sprintf("http://%s/api/register/?username=%s&password=%s", platform_url, username, password)
    fmt.Println(url)

    //检查用户注册
    subject := fmt.Sprintf("X项目服务器[%s]注册用户成功", login_server)
    content := fmt.Sprintf("注册用户成功, 服务器IP：%s, 用户名：%s, 密码：%s", login_server, username, password)
    err, ret := Check_register(platform_url, username, password)
    var reg interface{}
    err = json.Unmarshal([]byte(ret), &reg)
    fmt.Println(err, reg)
    fmt.Println(reflect.TypeOf(reg))
    m := reg.(map[string]interface{})
    result := false
    for _, v := range m {
        switch vv := v.(type) {
        case bool:
            result = vv
        default:
        }
    }
    fmt.Println(result)
    if err == nil && result {
        for _, email := range emails {
            fmt.Println(email)
            fmt.Println(SendMail(mail_user, mail_pass, mail_host, email, subject, content, "txt"))
        }
    }

    //检查用户登陆
    subject = fmt.Sprintf("X项目服务器[%s]用户登陆成功", login_server)
    content = fmt.Sprintf("用户登陆成功, 服务器IP：%s, 用户名：%s, 密码：%s", login_server, username, password)
    err, ret = Check_login(platform_url, username, password, login_server)
    var log interface{}
    err = json.Unmarshal([]byte(ret), &log)
    fmt.Println(err, log)
    fmt.Println(reflect.TypeOf(reg))
    m = reg.(map[string]interface{})
    result = false
    for _, v := range m {
        switch vv := v.(type) {
        case bool:
            result = vv
        default:
        }
    }
    fmt.Println(result)
    if err == nil && result {
        for _, email := range emails {
            fmt.Println(email)
            fmt.Println(SendMail(mail_user, mail_pass, mail_host, email, subject, content, "txt"))
        }
    }

}
