Mendapatkan nomor kode Status Http (200, 301, 404, dll.) Dari HttpWebRequest dan HttpWebResponse

Saya mencoba untuk mendapatkan nomor kode status HTTP dari HttpWebResponseobjek yang dikembalikan dari a HttpWebRequest. Saya berharap mendapatkan angka sebenarnya (200, 301.302, 404, dll.) Daripada deskripsi teks. ("Ok", "MovedPermanently", dll.) Apakah nomor itu terkubur di properti di suatu tempat di objek respons? Adakah ide selain membuat fungsi sakelar besar? Terima kasih.

HttpWebRequest webRequest = (HttpWebRequest)WebRequest
                                           .Create("http://www.gooogle.com/");
webRequest.AllowAutoRedirect = false;
HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
//Returns "MovedPermanently", not 301 which is what I want.
Console.Write(response.StatusCode.ToString());

Console.Write((int)response.StatusCode);

HttpStatusCode (tipe response.StatusCode) adalah enumerasi di mana nilai-nilai anggota cocok dengan kode status HTTP, misalnya

public enum HttpStatusCode
{
    ...
    Moved = 301,
    OK = 200,
    Redirect = 302,
    ...
}

Anda harus berhati-hati, respons server dalam kisaran 4xx dan 5xx melempar WebException. Anda perlu menangkapnya, dan kemudian mendapatkan kode status dari objek WebException:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

Sesuai 'dtb' Anda perlu menggunakan HttpStatusCode, tetapi mengikuti 'zeldi' Anda harus ekstra hati-hati dengan respons kode> = 400.

Ini berhasil bagi saya:

HttpWebResponse response = null;
HttpStatusCode statusCode;
try
{
    response = (HttpWebResponse)request.GetResponse();
}
catch (WebException we)
{
    response = (HttpWebResponse)we.Response;
}

statusCode = response.StatusCode;
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
sResponse = reader.ReadToEnd();
Console.WriteLine(sResponse);
Console.WriteLine("Response Code: " + (int)statusCode + " - " + statusCode.ToString());

Paksa saja StatusCodeke int.

var statusNumber;
try {
   response = (HttpWebResponse)request.GetResponse();
   // This will have statii from 200 to 30x
   statusNumber = (int)response.StatusCode;
}
catch (WebException we) {
    // Statii 400 to 50x will be here
    statusNumber = (int)we.Response.StatusCode;
}

//Response being your httpwebresponse
Dim str_StatusCode as String = CInt(Response.StatusCode)
Console.Writeline(str_StatusCode)
