HttpClient Time_wait - httpclient

Question

I make connector from unity to influxdb using HttpClient. but this problum it was so angre, how can i do this code edit? I learned c# 3weeks ago.... i tryed
private static readonly HttpClient client = new HttpClient();
but many more new create tcp... time_wait
this is my code
code 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();
}
code 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();
}

Answer 1

The simplest solution is to 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();
}
}
}
