golang中http请求时出现错误 socket: too many open files, Attempt 1 | Go | Go 技术论坛

使用的库 go-resty/resty
代码如下

func httpGet(debug bool, url string, queryParam map[string]string) (*resty.Response, error) {
    client := resty.New()
    client.OnBeforeRequest(func(c *resty.Client, req *resty.Request) error {
        var sign string = strconv.Itoa(time.Now().Nanosecond()) + queryParam["account_id"]
        req.QueryParam.Set("nonce", util.MD5(sign))
        return nil // if its success otherwise return error
    })
    client.SetDebug(debug)
    client.SetTimeout(20 * time.Second)
    client.SetAllowGetMethodPayload(true)
    client.
        SetRetryCount(3).
        SetRetryWaitTime(5 * time.Second).
        SetRetryMaxWaitTime(10 * time.Second)
    client.AddRetryCondition(
        func(r *resty.Response, rr error) bool {
            if r.StatusCode() != http.StatusOK {
                return true
            }
            result := &MaterialReportResponse{}
            json.Unmarshal(r.Body(), result)
            if result.Code == 10000 || result.Code == 12100 {
                return true
            }
            return false
        },
    )
    resp, err := client.R().
        SetHeaders(map[string]string{"Content-Type": "application/json"}).
        SetQueryParams(queryParam).
        Get(url)
    if err != nil {
        util.SugarLogger.Errorf("Request error: url:%s, error:%s", url, err)
    }
    return resp, err
}
