HttpClient getAsync只工作一次

Question

我试图调用端点在我的网站上获得一些信息，但当我运行getAsync时，它只在当前进程中第一次工作。

static async Task Main(string[] args)
{
await GetUserInfo("srmilton"); //Working
await GetUserInfo("srmilton"); //Not Working
while (true)
{
var res = await GetUserInfo("srmilton");
}
}
public static async Task<(string,string)> GetUserInfo(string username)
{
string url = "https://www.mywebsite.com/api/user/detail";
var baseAddress = new Uri(url);
using (var handler2 = new HttpClientHandler { UseCookies = false })
using (var client2 = new HttpClient(handler2) { BaseAddress = baseAddress })
{
client2.DefaultRequestHeaders.Clear();
client2.DefaultRequestHeaders.Add("Cookie", "session=zgbEqIjfSC7M7QdTTpHDkpWLt");
client2.DefaultRequestHeaders.Add("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) 
AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36");
client2.DefaultRequestHeaders.Add("x-requested-with", "XMLHttpRequest");
client2.DefaultRequestHeaders.Add("referer", "https://www.mywebsite.com/");
var result = await client2.GetAsync("");
string responseString = await result.Content.ReadAsStringAsync();
dynamic jsonresponse = JObject.Parse(responseString);
id = jsonresponse.userInfo.user.id;
sec_id = jsonresponse.userInfo.user.secUid;
return (id, sec_id);
}
}

函数GetUserInfo第一次被调用，它从api返回正确的json响应，但第二个循环在GetAsync中卡住。我已经试过.ConfigureAwait(false).Result甚至创建HttpClient只有一次和重用但总是挂在第二个循环。

我不知道我做错了什么，如果有人能解释并展示正确的方法来使这个工作，我会很感激。

解决。我的getAsync报头上缺少一个Accept报头。

client2.DefaultRequestHeaders.Add("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9");
