domainCheck_go

what it can do

• auto check domain regist status
• auto update domain expiry time
• notice by email when a high value can be registed

require

require	version
go	1.11
GameEngine_go	v1.0.0
go-sql-driver/mysql	v1.4.1

how to start

1. clone repository

git clone [email protected]:coderguang/domainCheck_go.git domainCheck_go

2. import a null sql table to you mysql,sql file in sql/domain_info.sql

3. config your database and email infomation in config/config.json

{
    "Dburl":"localhost",  //your mysql database url
    "Dbport":"3306",  //database port
    "Dbuser":"test", //database user
    "Dbpwd":"test", //database password
    "Dbname":"domain", //database name
    "DoroutinesNum":5, //how many coroutine to check domain(only first run use)
    "EmailFrom":"",  //notice email from,empty mean wouldn't notice by email
    "EmailPwd":"", //notice email password
    "EmailTo":"[email protected]", //receiver 
    "Smtp":"smtps://smtp.exmail.qq.com", //smtp addr
    "SmtpPort":"465"  //smtp port
}

4. procedure for execution

go run main.go config/config.json

5. if no problem,the output message should like this:

enter any key ,it would show command,if first run,enter ["StartGenDataAndCheck"] to create domain file and start run,if not first run,just enter ["StartCheckByDb"] for scanner by database data. after enter ["StartGenDataAndCheck"],output message should like this

6. all log will write in log/xx-xx-xx.log

you can also get domain info in you database,like below:

status means:

const SG_WHOIS_STATUS_CHECK_FAILD int = -1   //receive domain server failed,will recheck in next time
const SG_WHOIS_STATUS_CAN_REGIST_NOW int = 0  //can registed now
const SG_WHOIS_STATUS_HAD_REGIST int = 1 //had been registed
const SG_WHOIS_STATUS_LIMIT_BY_GOVERNMENT int = 2 //govenment forbidden,if you search cn ,you will get this

7. others

1. now only will gen com、cn、net and pure num domains,if you want to change it ,you should modify code in src/genTxt/genTxt.go

unc CreateDominFile(fileName string) {
	path, err := sgfile.GetPath(fileName)
	if err != nil {
		sglog.Error("get path error,err=%s", err)
		sgthread.DelayExit(2)
	}
	sgfile.AutoMkDir(path)
	file, err := os.OpenFile(fileName, os.O_RDWR|os.O_CREATE, 0766)
	if err != nil {
		sglog.Error("open file error,err=%s", err)
		sgthread.DelayExit(2)
	}
	allList := []string{}
	allList = append(allList, numlist...)
	allList = append(allList, charlist...)
	//create all
	sum := 0
	tmpSum := createDomainFileAndWrite(allList, 1, file)
	sum += tmpSum
	tmpSum = createDomainFileAndWrite(allList, 2, file)
	sum += tmpSum
	tmpSum = createDomainFileAndWrite(allList, 3, file)
	sum += tmpSum
	//create only num
	tmpSum = createDomainFileAndWrite(numlist, 4, file)
	sum += tmpSum
	tmpSum = createDomainFileAndWrite(numlist, 5, file)
	sum += tmpSum

	//create only char
	tmpSum = createDomainFileAndWrite(charlist, 4, file)
	sum += tmpSum

	defer file.Close()
	sglog.Info("sum is %d", sum)
}

func createDomainFileAndWrite(srcList []string, num int, file *os.File) (sum int) {
	sglog.Info("now gen %s,num=%d", srcList, num)
	sum = 0
	result := []string{}
	sgalgorithm.GenPermutation(srcList, num, &result)
	zonelist := []string{"com", "cn", "net"} //modify domain
	for _, n := range result {
		for _, k := range zonelist {
			str := n + "." + k + "\n"
			file.Write([]byte(str))
			sum++
		}
	}
	sglog.Info("gen success total num=%d", sum)
	return
}

2. if you want to change high value domain rule ,you should modify code in src/sacnner/scanner.go

func HightValueNotice(result *sgwhois.Whois) {
	if sgwhois.IsHightValueDomainByName(result.Domain) {
		time_now := sgtime.New()
		if sgwhois.SG_WHOIS_STATUS_CAN_REGIST_NOW == result.IsRegist {
			domainCheckMail.SendMailNotice(result.Domain, "  can regist now")
			sglog.Info("luck domain ", result.Domain, " can regist now")
		} else if sgwhois.SG_WHOIS_STATUS_LIMIT_BY_GOVERNMENT != result.IsRegist && result.ExpiryDt.Before(time_now) {
			//SendMailNotice( domain, config, "  can regist "+result.ExpiryDtStr)
			sglog.Info("luck domain %s can regist at %s", result.Domain, result.ExpiryDtStr)
		}
	}
}
