我正在使用下面的代碼通過 WebRequest 從我的 C# 代碼進行 API 調用：public object GetData() { object response = ""; string token = "EF232354"; string baseUrl = ConfigurationManager.AppSettings["BaseURL"].ToString(); string endPoint = ConfigurationManager.AppSettings["EndPoint"].ToString(); var httpWebRequest = (HttpWebRequest) WebRequest.Create(baseUrl + endPoint); httpWebRequest.ContentType = "application/json"; httpWebRequest.Method = HttpVerb.GET.ToString(); httpWebRequest.Headers.Add("token", token); var httpResponse = (HttpWebResponse) httpWebRequest.GetResponse(); Stream dataStream = httpResponse.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); using(JsonReader sdr = new JsonTextReader(reader)) { JsonSerializer serializer = new JsonSerializer(); response = serializer.Deserialize(sdr); } return response;}有時我會得到：消息：遠程服務器返回錯誤：（504）網關超時。異常類型：System.Net.WebExceptionWebRequest 一次可以發出多少個請求？

當我注意到響應沒有被處理時，我正在調整問題以演示對內存流的讀取。這有 95% 可能是您的潛在問題。Streams 和 StreamReaders 也是一次性的，應該使用 using() 閉包進行包裝。
public object GetData()
{
object response = "";
string token = "EF232354";
string baseUrl = ConfigurationManager.AppSettings["BaseURL"].ToString();
string endPoint = ConfigurationManager.AppSettings["EndPoint"].ToString();
var httpWebRequest = (HttpWebRequest) WebRequest.Create(baseUrl + endPoint);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = HttpVerb.GET.ToString();
httpWebRequest.Headers.Add("token", token);
using (var httpResponse = (HttpWebResponse) httpWebRequest.GetResponse())
{
using (Stream dataStream = httpResponse.GetResponseStream())
{
using (StreamReader reader = new StreamReader(dataStream))
{
using(JsonReader sdr = new JsonTextReader(reader))
{
JsonSerializer serializer = new JsonSerializer();
response = serializer.Deserialize(sdr);
}
return response;
}
}
httpResponse.Close(); // For good measure. *should* be covered by Dispose.
}
}
