Golang url.Parse总是返回无效的控制字符URL

Question

I'm trying to scrape some site using proxy that i get from free-proxy-list.net and apply it in my local http request using Golang, but when i parse the proxy using url.Parse() always return Invalid Control Character URL

func getProxy() *url.URL {
    proxyUrl := "https://www.proxy-list.download/api/v1/get?type=http&country=US"
    client := &http.Client{}
    req, err := http.NewRequest("GET", proxyUrl, nil)
    resp, err := client.Do(req)
    if err != nil {
        fmt.Println("Error proxy ", err)
    }
    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        fmt.Println("Error response body", err)
    }
    details := string(body)
    temp := strings.Split(details, "
")
    fmt.Println("http://" + temp[rand.Intn(30)])
    checkProxy, err := url.Parse("http://" + temp[rand.Intn(10)])
    if err != nil {
        fmt.Println("Bad proxy URL", err)
    }

    return checkProxy
}

proxyUrl := "https://www.proxy-list.download/api/v1/get?type=http&country=US"

The content of this URL are lines in the format ip:port ´, i.e. the line delimiter is `, (DOS/Windows style).

temp := strings.Split(details, "
")

This splits the content by , i.e. the UNIX style line delimiter. This leaves the from the DOS line delimiter in the string, resulting in ip:port.

... always return Invalid Control Character URL

It is the remaining in the line it is complaining about.
