如何重试HTTP POST请求

我已经实现了以下代码,用于在Go中重试http发布请求。

在第二次重试尝试中,我总是将请求正文设为null。我试过推迟req.body.close(),但是它不起作用。谁能帮我解决这个问题?

func httpRetry(req *http.Request, timeOut time.Duration, retryAttempts int, retryDelay time.Duration) (*http.Response, error) {

    attempts := 0

    for {
        attempts++
        fmt.Println("Attempt - ", attempts)
        statusCode := 0

        tr := &http.Transport{
            TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
        }
        var netClient = &http.Client{
            Timeout:   time.Second * timeOut,
            Transport: tr,
        }
        fmt.Println("ret 88888 ", req)
        response, err := netClient.Do(req)

        //defer req.Body.Close()

        fmt.Println(response, "  dd", err)

        if response != nil {
            fmt.Println(response.StatusCode)
            statusCode = response.StatusCode
        }

        if err != nil {
            fmt.Println(err)
            //return response, err
        }

        if …
