Question

我想为使用代理创建带有选项true / false的简单函数。这是我的实际代码：

var torProxy string = "socks5://127.0.0.1:9050"

func getPage(webUrl string, useProxy bool) {
    torProxyUrl, err := url.Parse(torProxy)
    if err != nil {
        log.Fatal("Error parsing Tor proxy URL:", torProxy, ".", err)
    }

    transport := &http.Transport{
        DisableKeepAlives: true,
    }
    torTransport := &http.Transport{Proxy: http.ProxyURL(torProxyUrl)}
    client := &http.Client{Transport: transport, Timeout: time.Second * 5}
    if useProxy {
        client = &http.Client{Transport: torTransport, Timeout: time.Second * 5}
    }

    // Make request
    resp, err := client.Get(webUrl)
    if err != nil {
        log.Fatal("Error making GET request.", err)
    }
    defer resp.Body.Close()

    // Read response
    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        log.Fatal("Error reading body of response.", err)
    }
    log.Println(string(body))
    log.Println("Return status code:", resp.StatusCode)
}

func main() {
    getPage("getPage", false)
}

当我执行我的代码时，返回此错误：2018/04/19 08:28:25 Error making GET request.Get getPage: unsupported protocol scheme "" exit status 1我错了吗？

您在通话中传递的网址无效。变化

func main() {
    getPage("getPage", false)
}

到

func main() {
    const urlStr = 'https://stackoverflow.com' // Or whatever URL
    getPage(urlStr, false)
}

使用代理设置true false
