Próbuję opublikować Json w naszym serwisie internetowym. Mój problem polega na tym, że gdy moje żądanie.ContentLength przekracza 7kb. Otrzymam wyjątek sieciowy 500 na request.GetResponse(). Ale jeśli moje żądanie.ContentLength jest poniżej 7kb, mój post jest pomyślnie wysyłany.Nie można publikować w WebRequest, jeśli długość zawartości> 7kb przy użyciu C#
Komunikat o błędzie: Kod
The remote server returned an error: (500) Internal Server Error.
Źródło:
public static string JsonPost(string url, string method, string postData)
{
Uri address = new Uri(url + method);
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
byte[] byteData = UTF8Encoding.UTF8.GetBytes(postData);
request.ContentLength = byteData.Length;
using (Stream postStream = request.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
}
try
{
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string JsonResponse = reader.ReadToEnd();
return JsonResponse;
}
}
catch (WebException ex)
{
string message = ((System.Net.HttpWebResponse)(ex.Response)).StatusDescription;
if (message.Contains("busy"))
return message;
else
throw new Exception(message);
}
}

Wygląda na to, że problem jest prawdopodobnie w służbie sieci ... –
Hi Jon, hmm usługa WWW został skonfigurowany tak, aby pozwala 2147483647 maksymalną długość żądania. Próbowaliśmy również ustalić punkt przerwania, ale usługa internetowa nie otrzymała żadnego postu. jeśli długość zawartości> 7kb –
Cóż, dostajesz 500 - co sugeruje wewnętrzny błąd * gdzieś *. Proponuję przyjrzeć się wszystkim dostępnym dziennikom. –
