当她发现文本发生变化，从一个循环中走出时，我的程序每隔20秒检查一次网站上Rebody的文本更改和她包含在循环中的IP地址已经不可能了，因为无休止的goroutine已经开始写入所有发现的ip地址的信息，我已经无法进入验证。我需要以某种方式在验证时停止goroutine，检查并再次启动。 怎么做？ 代码：
func main() {
url := os.Args[1]
for {
time.Sleep(time.Second * 20) /* check every 20 seconds */
req, err := http.Get(url)
if err != nil {
fmt.Println("error 404")
} else {
defer req.Body.Close()
simple_match_body, io_err := ioutil.ReadAll(req.Body)
if io_err != nil {
fmt.Println("[Info] [IO.Fatal.Method.Read] IO-Error reading body... retry")
continue
} else {
check_rebody := regexp.MustCompile("Rebody")
match_result := check_rebody.FindAll(simple_match_body, -1)
for _, tq := range match_result {
query_response := fmt.Sprintf("%s", tq)
fmt.Println(query_response)
}
if len(match_result) == 0 {
fmt.Println("'Rebody' not found!")
} else {
fmt.Println("'Rebody' - found!", req.Body)
}
check_url := regexp.MustCompile(`((25[0-5]|2[0-4]\d|[01]?\d\d?)\.){3}(25[0-5]|2[0-4]\d|[01]?\d\d?)`) // теперь подставляется регулярное выражение для поиска ip адресов
match_result_a := check_url.FindAll(simple_match_body, -1)
for _, dddd := range match_result_a {
def_url := fmt.Sprintf("http://"+"%s", dddd)
for i := 0; i < 2; i++ {
go HTTPRequests(def_url, 80)
}
fmt.Println(def_url)
}
if len(match_result_a) == 0 {
fmt.Println("Url is found!", check_url)
} else {
fmt.Println("Url not found!", req.Body)
}
}
}
}
}
func HTTPRequests(url string, port int) {
for {
flags_http, s_err := http.Get(url)
if s_err != nil {
fmt.Println("error 404")
} else {
fmt.Println("request has been send: ", flags_http.Body, flags_http.Header)
}
time.Sleep(time.Second * 5)
http_recheck, ss_err := http.Get(url)
if ss_err != nil {
fmt.Println("ss err")
} else {
defer http_recheck.Body.Close()
simple_match_body, io_err := ioutil.ReadAll(http_recheck.Body)
if io_err != nil {
fmt.Println("error")
} else {
check_word := regexp.MustCompile("None")
match_result := check_word.FindAll(simple_match_body, -1)
for _, tq := range match_result {
query := fmt.Sprintf("%s", tq)
fmt.Println(query)
}
if len(match_result) == 0 {
fmt.Println("ip not found")
} else {
fmt.Println("ip found.", http_recheck.Body)
}
}
}
}
}
