I have .NET Standard 2.1 library to communicate with HTTP API with digest authentication. Here is C# code:
var credCache = new CredentialCache
{
{
new Uri($"http://192.168.13.100/"),
"Digest",
new NetworkCredential("admin", "admin")
}
};
var httpClientHandler = new HttpClientHandler
{
PreAuthenticate = true,
Credentials = credCache
};
httpClient = new HttpClient(httpClientHandler);
SendSMS sendSms = new SendSMS()
{
text = message,
param = new SendSMSParam[1] {
new SendSMSParam()
{
number = phone,
user_id = messageId
}
},
port = new int[1] { port },
encoding = "unicode",
request_status_report = true,
};
string json = JsonConvert.SerializeObject(sendSms);
HttpResponseMessage response = await httpClient.PostAsync("http://192.168.13.100/api/send_sms", new StringContent(json));
string answer = await response.Content.ReadAsStringAsync();
The problem is that answer from first request is:
HTTP/1.1 401 Unauthorized Server: Web Server/2.1.0 PeerSec-MatrixSSL/3.9.5-OPEN Date: Wed Jun 3 14:04:34 2020 WWW-Authenticate: Digest realm="Web Server", domain="",qop="auth", nonce="7d65e9cdaa4eea9a6b12d10bda58269a", opaque="5ccc069c403ebaf9f0171e9517f40e41",algorithm="MD5", stale="FALSE" Set-Cookie: devckie=db39-a230-9038-0160;path=/ Pragma: no-cache Cache-Control: no-cache Content-Type: text/html
Document Error: Unauthorized Access Error: Unauthorized Access to this document requires a User ID
The httpclient have to make second request with proper authorization but second request is not send. I search for solution about two days without success. Does someone know solution about this problem. T try solution from this question:.Net Core HttpClient Digest Authentication but not work for me. The HTTP API works correctly with POSTMAN and web browser(Firefox, Edge etc.).
