go http客户端在多次请求后失败

我正在应用程序中使用golang的net/http包。在我的用例中，我尝试使用我的自定义http客户机连续多次进行http调用。我在这方面面临以下问题

问题1:在多次调用[~100次，不到一分钟]之后，客户端无法进行调用。我的意思是请求没有击中服务器

这是我的自定义客户端代码

package serviceclient

import (
    "bytes"
    "io/ioutil"
    "net"
    "net/http"
    "time"
    "log"
)

const(
    HTTP_DIAL_TIME_OUT          = 5    //seconds
    HTTP_TLS_HANDSHAKE_TIME_OUT = 5
    HTTP_CLIENT_TIME_OUT        = 10
)

// RequestService requests the api through the service URL
func RequestService(methodType string, serviceURL string, data string, contentType string) string {
    log.Printf("Request string %s", data)
    dataBytes := bytes.NewBufferString(data)
    req, err := http.NewRequest(methodType, serviceURL, dataBytes)
    if err != nil {
        log.Printf("Client request creation issue")
    }
    req.Header.Set("Content-Type", contentType)

    client := getHTTPClient()
    res, err := client.Do(req)
    log.Printf("Response Object original : %s", res)
    if err != nil {
        log.Printf("Could not make the client request")
    }
    defer res.Body.Close()
    responseBytes, err := ioutil.ReadAll(res.Body)
    if err != nil {
        log.Printf("Response string conversion issue")
    }
    responseString := string(responseBytes[:])
    return responseString
}

func getHTTPClient() *http.Client {
    var netTransport = &http.Transport{
          Dial: (&net.Dialer{
            Timeout: HTTP_DIAL_TIME_OUT * time.Second,
          }).Dial,
          TLSHandshakeTimeout: HTTP_TLS_HANDSHAKE_TIME_OUT * time.Second,
        }
    var client = &http.Client{
          Timeout: time.Second * HTTP_CLIENT_TIME_OUT,
          Transport: netTransport,
        }
    return client
}

问题2:即使在成功响应空请求[而不是原始请求]之后，客户机每次尝试拨打电话时也是如此。我的意思是，当我调用RequestService（）函数时，即使在获得成功响应后，它也会进行5次额外调用。但是对于这些调用，

request

值是

undefined

这是我的控制台输出[我打印了http请求和少量信息]，用于一个http调用

我做错什么了吗？有人能帮我吗？

您的所有请求都应该使用一个http客户端。创建许多相同的客户机是没有意义的。只要超时相同，就使用相同的客户端。它可能会解决你的问题。客户端不是连接，它有内部连接池和缓存等。@not_A_Golfer-它帮助我解决了我猜的第一个问题[做了一个简单的测试]。我感谢你的帮助。但另一个问题仍然存在：（.我想是与默认重试有关的。我不确定“客户端”是什么意思。它可能更与数据字符串周围的缓冲区有关。@not_a_Golfer-我的意思是在调用RequestService（）时）函数，即使在获得成功响应后，它也会进行5次额外调用。但是对于这些调用，

请求

值为

未定义

。您需要显示如何进行这5次额外调用
