HttpClient Time_wait

Question

我用HttpClient制作了unity到influxdb的连接器。但是这个问题实在是太棒了，我该怎么做这个代码编辑呢？我在3周前学会了c# ....我尝试了私有静态只读HttpClient客户端=新的HttpClient()；

但还有更多新的创建tcp...time_wait

​

这是我的代码

代码1

public async Task GetPositionAsync()
{
    using (HttpClient client = new HttpClient())
    {
        using (HttpResponseMessage response = await client.GetAsync(Url))
        {
            using (HttpContent content = response.Content)
            {
                 getdata = content.ReadAsStringAsync().Result;
            }
        }
    }

    client.Dispose();
}

代码2

    HttpClient client = new HttpClient();

    int refreshTime = 5;

    client.DefaultRequestHeaders.Add("Authorization", "Token " + token);
    //client.DefaultRequestHeaders.Add("Accept", "application/csv");
    client.DefaultRequestHeaders.Add("Accept-Encoding", "gzip");

    var fluxQuery = "from(bucket: \"DT_Object\")\n"
                   + "|> range(start: -6h)"
                   + "|> filter(fn: (r) => r[\"_measurement\"] ==\" NPC\")"
                   + "|> filter(fn: (r) => r[\"NAME\"] == \"NPC\")"
                   + "|> filter(fn: (r) => r[\"_field\"] == \"X\" or r[\"_field\"] == \"Y\" or r[\"_field\"] == \"Z\")"
                   + "|> aggregateWindow(every: " + refreshTime + "s, fn: mean, createEmpty: false)"
                   + "|> yield(name: \"mean\")";

    var data = new StringContent(fluxQuery, Encoding.UTF8, "application/vnd.flux");

    var response = await client.PostAsync(requestUrl, data);
    Debug.Log(response);
    // var responseString = await client.GetStringAsync(requestUrl);
    // Debug.Log("get data : " + responseString);
    //response.Content = "application/CSV";
    var result = response.Content.ReadAsByteArrayAsync();

    Debug.Log("데이터 읽어줘 " + result.ToString());

    if (result == null)
    {
        Debug.Log("결과없음");
    }

    Debug.Log("result : " + result);



    client.Dispose();
}

最简单的解决方案是reuse HttpClient

private static readonly HttpClient client = new();
public async Task GetPositionAsync()
{
    using (HttpResponseMessage response = await client.GetAsync(Url))
    {
        using (HttpContent content = response.Content)
        {
             getdata = await content.ReadAsStringAsync();
        }
    }
}
