Пытаюсь реализовать код из
этой статьи. Суть статьи состоит в том, что мы при помощи xml запросов говорим роутеру открыть порт, если я все правильно понял.
1. В первом пустом GET-запросе получаем от роутера ответ под спойлером.

Далее статья говорит, что нужно взять строку controlURL, рядом с которой serviceType равен urn:schemas-upnp-org:service:WANIPConnection:1. В моем случае это
<controlURL>/control?WANIPConnection</controlURL>
2. Теперь отправляем POST-запрос на
192.168.0.1:1980/control с просьбой открыть порт. Код моего запроса под спойлером.
Тыкpublic static void AddPort(string webPath, int port, string protocol, string locIP, string desc)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(webPath);
HttpWebResponse response;
string query, responseStr;
byte[] data;
request.Method = "POST";
request.Headers.Add("Cache-Control", "no-cache");
request.Headers.Add("Pragma", "no-cache");
request.Headers.Add("SOAPAction", "\"urn:schemas-upnp-org:service:WANIPConnection:1#AddPortMapping\"");
request.ContentType = "text/xml; charset=\"utf-8\"";
request.UserAgent = "Microsoft-Windows/6.1 UPnP/1.0";
query = "<?xml version=\"1.0\"?>" +
"<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">" +
"<SOAP-ENV:Body><m:AddPortMapping xmlns:m=\"urn:schemas-upnp-org:service:WANIPConnection:1\">" +
"<NewRemoteHost xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"string\"></NewRemoteHost>" +
"<NewExternalPort xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"ui2\">" + port + "</NewExternalPort>" +
"<NewProtocol xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"string\">" + protocol + "</NewProtocol>" +
"<NewInternalPort xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"ui2\">" + port + "</NewInternalPort>" +
"<NewInternalClient xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"string\">" + locIP + "</NewInternalClient>" +
"<NewEnabled xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"boolean\">1</NewEnabled>" +
"<NewPortMappingDescription xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"string\">" + desc + "</NewPortMappingDescription>" +
"<NewLeaseDuration xmlns:dt=\"urn:schemas-microsoft-com:datatypes\" dt:dt=\"ui4\">0</NewLeaseDuration></m:AddPortMapping>" +
"</SOAP-ENV:Body></SOAP-ENV:Envelope>";
data = Encoding.UTF8.GetBytes(query);
request.ContentLength = data.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
responseStr = String.Empty;
response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
responseStr = sr.ReadToEnd();
}
Console.WriteLine(responseStr);
}
Проблема в следующем: при отправке этого запроса попросту вылетает WebExcepton с текстом "The server committed a protocol violation. Section=ResponseStatusLine" на строке
response = (HttpWebResponse)request.GetResponse();
Есть преположения почему это и как исправить (и открыть-таки порт)?
