Why HttpWebRequest and method POST data is not seen by the server

When I post to server using HttpWebRequest and method POST, the NameValueCollection in the asp code has no values. I have identical code working with other server pages, the only difference is the string data posted is a bit different.
code that posts is from a c# desktop application:
string responseFromServer = string.Empty;
System.Net.HttpWebRequest request = null;
System.IO.StreamReader reader = null;
System.Net.HttpWebResponse response = null;
string http = string.Empty;
http = "http://www.apageonmywebsite.aspx";
request = HttpWebRequest.Create(http) as HttpWebRequest;
request.Method = "POST";
UTF8Encoding encoding = new UTF8Encoding();
//send a namevalue pair -that is what the website expects via the request object
string postData = "TRIALID=" + System.Web.HttpUtility.UrlEncode(trialUserID, encoding);
byte[] byte1 = encoding.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byte1.Length;
request.Timeout = 20000;
System.IO.Stream newStream = request.GetRequestStream();
newStream.Write(byte1, 0, byte1.Length);
newStream.Close();
System.Threading.Thread.Sleep(1000);
response = (HttpWebResponse)request.GetResponse();
System.IO.Stream dataStream = response.GetResponseStream();
reader = new System.IO.StreamReader(dataStream);
responseFromServer = reader.ReadToEnd();
if (responseFromServer.Contains("\r"))
{
responseFromServer = responseFromServer.Substring(0, responseFromServer.IndexOf("\r"));
}
Server code:
NameValueCollection postedValues = Request.Form; // Request.Form worked locally, failed on server(count=0)
IEnumerator myEnumerator = postedValues.GetEnumerator();
try
{
foreach (string s in postedValues.AllKeys)
{
if (s == "TRIALID")
{
regcode += postedValues[s];
break;
}
}
}
catch (Exception ex)
{
Response.Clear();
Response.Write("FAILED");
this.resultMsg = "FAILED. Exception: " + ex.Message;
LogResult();
return;
}
if (string.IsNullOrEmpty(regcode))
{
Response.Write("postedvalues count=" + postedValues.Count.ToString() + ": no regcode:");
this.resultMsg ="postedvalues count=" + postedValues.Count.ToString() + ": no regcode:";
LogResult();
return;
}
In the sending application, responseFromServer is postedvalues count=0:no regcode:
So the data is posted but not "seen" on the server.
The trialUserID field used in the urlencode method is a string containing user domain name plus user name from the Environment object plus the machine name.

Answer to my own question is that the url needs to be https not http.
I converted my asp.net website to https one year ago and when I created the app that sends the posted data I assumed that since the entire website is configured to automatically redirect to https that should take care of it. Clearly, the webrequest needs the https hardcoded in the url.
Just tried to click the Accept button but that is not allowed for two days since I answered my own question.

Is there any possibility to send post with body using OAuth 1.0?

i am trying to send a POST request with body to WordPress API. I am still getting 401 error.
I decided to use: https://gist.github.com/DeskSupport/2951522 to authorize via OAuth 1.0 and it works perfectly with GET method. Then i wanted to implement another method which sends simple body.
That's my code:
var oauth = new OAuth.Manager();
oauth["consumer_key"] = _consumerKey;
oauth["consumer_secret"] = _consumerSecret;
oauth["token"] = _accessToken;
oauth["token_secret"] = _tokenSecret;
var appUrl = _baseUrl + url;
var authzHeader = oauth.GenerateAuthzHeader(appUrl, "POST");
string body = GenerateBody(parameters);
byte[] encodedData = Encoding.ASCII.GetBytes(body);
var request = (HttpWebRequest)WebRequest.Create(appUrl);
request.Method = "POST";
request.PreAuthenticate = true;
request.AllowWriteStreamBuffering = true;
request.Headers.Add("Authorization", authzHeader);
request.ContentLength = encodedData.Length;
request.ContentType = "application/x-www-form-urlencoded";
Stream newStream = request.GetRequestStream();
newStream.Write(encodedData, 0, encodedData.Length);
using (var response = (HttpWebResponse)request.GetResponse())
{
if (response.StatusCode != HttpStatusCode.OK)
{
}
}
The result of method GenerateBody is user_login=login&user_pass=BXE&04K44DoR1*a
I also tried to change the '&' character to '%26' but it didn't work.
This request works via Postman and i don;t know what's wrong.

OK, I found a solution.
https://blog.dantup.com/2016/07/simplest-csharp-code-to-post-a-tweet-using-oauth/
This guy wrote the way to make this request. What is also important you have to change a oauth_nonce for unique token.

C# eBay OAuth Compliance API Authentication Problems

After many struggles, I was finally able to get the OAuth Authentication/Refresh token process down. I am certain that the tokens I am using in this process are good. But I am struggling to communicate with the Compliance API and I think it may have more to do with my headers authentication process than it does specifically the Compliance API but I am not certain. I've tried so many different combinations of the below code unsuccessfully. I've tried to do the call as a GET and a POST (the call should be a GET). I've tried it with the access token encoded and not encoded. With all of my different code combinations tried I've been getting either an authorization error or a bad request error. You can see some of the various things I've tried from commented out code. Thank you for your help.
public static string Complaince_GetViolations(string clientId, string ruName, string clientSecret, string accessToken, ILog log)
{
var clientString = clientId + ":" + clientSecret;
//byte[] clientEncode = Encoding.UTF8.GetBytes(clientString);
//var credentials = "Basic " + System.Convert.ToBase64String(clientEncode);
byte[] clientEncode = Encoding.UTF8.GetBytes(accessToken);
var credentials = "Bearer " + System.Convert.ToBase64String(clientEncode);
var codeEncoded = System.Web.HttpUtility.UrlEncode(accessToken);
HttpWebRequest request = WebRequest.Create("https://api.ebay.com/sell/compliance/v1/listing_violation?compliance_type=PRODUCT_ADOPTION")
as HttpWebRequest;
request.Method = "GET";
// request.ContentType = "application/x-www-form-urlencoded";
//request.Headers.Add(HttpRequestHeader.Authorization, credentials);
//request.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + codeEncoded);
request.Headers.Add(HttpRequestHeader.Authorization, credentials);
//request.Headers.Add("Authorization", "Bearer " + codeEncoded);
request.Headers.Add("X-EBAY-C-MARKETPLACE-ID", "EBAY-US");
log.Debug("starting request.GetRequestStream");
string result = "";
var response = (HttpWebResponse)request.GetResponse();
using (var streamReader = new StreamReader(response.GetResponseStream())) //FAILS HERE
{
result = streamReader.ReadToEnd();
}
//DO MORE STUFF BELOW
return "STUFF";
}

And I finally figured out a resolution to this problem. The HTML encoding of the entire bearer string was the issue. If anyone needs this in the future your welcome. =)
HttpWebRequest request = WebRequest.Create("https://api.ebay.com/sell/compliance/v1/listing_violation?compliance_type=PRODUCT_ADOPTION")
as HttpWebRequest;
request.Method = "GET";
request.Headers.Add(HttpRequestHeader.Authorization, System.Web.HttpUtility.HtmlEncode("Bearer " + accessToken));
request.Headers.Add("X-EBAY-C-MARKETPLACE-ID", "EBAY-US");
log.Debug("starting request.GetRequestStream");
string result = null;
var response = (HttpWebResponse)request.GetResponse();
using (var streamReader = new StreamReader(response.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}

Get GitHub Rest API User info C# code

https://api.github.com/users/[UserName] can be accessed via browser. I get a Json result. But I want to retrieve the same information programmatically.
I'm using the below code, which is not working as expected. Please advice.
var credentials =
string.Format(System.Globalization.CultureInfo.InvariantCulture, "{0}:",
githubToken);
credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(credentials));
client.DefaultRequestHeaders.Authorization = new
AuthenticationHeaderValue("Basic", credentials);
var contents =
client.GetStreamAsync("https://api.github.com/users/[userName]").Result;
As a result of the above code, I'm getting "Aggregate Exception".
How to achieve the requirement using c# code??? Please help
Note: Not expecting a solution with Octokit. Need proper c# code.

I found the solution. Here is the code.
HttpWebRequest webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
if (webRequest != null)
{
webRequest.Method = "GET";
webRequest.UserAgent = "Anything";
webRequest.ServicePoint.Expect100Continue = false;
try
{
using (StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream()))
{
string reader = responseReader.ReadToEnd();
var jsonobj = JsonConvert.DeserializeObject(reader)
}
}
catch
{
return;
}
}

HP ALM 12.21 REST API - 401 Unauthorized - C#

I am trying to use the API against our ALM 12.21 server, but always ends up with "401 Unauthorized". It seems that I get the auth cookie back correctly, but when I try to do something after that I am unauthorized.
I use this the get this to get auth cookie (seems to work):
HttpWebRequest myauthrequest = (HttpWebRequest)WebRequest.Create("https://server/qcbin/authentication-point/alm-authenticate");
string AuthenticationXML = #"<alm-authentication>
<user>username</user>
<password>password</password>
</alm-authentication>";
byte[] Requestbytes = Encoding.UTF8.GetBytes(AuthenticationXML);
myauthrequest.Method = "POST";
myauthrequest.ContentType = "application/xml";
myauthrequest.ContentLength = Requestbytes.Length;
myauthrequest.Accept = "application/xml";
Stream RequestStr = myauthrequest.GetRequestStream();
RequestStr.Write(Requestbytes, 0, Requestbytes.Length);
RequestStr.Close();
HttpWebResponse myauthres = (HttpWebResponse)myauthrequest.GetResponse();
var AuthenticationCookie = myauthres.Headers.Get("Set-Cookie");
AuthenticationCookie = AuthenticationCookie.Replace(";Path=/;HTTPOnly", "");
I am not sure if the .Replace is needed. Just read it somewhere. I get 401 both with or without it though, when trying to do subsequent requests.
Trying e.g. this after getting auth cookie:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://server/qcbin/rest/domains/FS/projects/P3602_SLS_Project/defects/1");
req.Method = "GET";
req.ContentType = "application/xml";
req.Accept = "application/octet-stream";
req.Headers.Set(HttpRequestHeader.Cookie, AuthenticationCookie);
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
Stream RStream2 = res.GetResponseStream();
XDocument doc = XDocument.Load(RStream2);
Which fails with 401.
Anyone have complete working code for the ALM 12.21 REST API?

You need two main cookies to get the ALM REST API works perfectly.
LWSSO_COOKIE_KEY
QCSession
almURL = "https://..com/qcbin/"
authEndPoint = almURL + "authentication-point/authenticate"
qcSessionEndPoint = almURL + "rest/site-session"
After you get successful response for authEndPoint you will get the LWSSO_COOKIE_KEY
Use that cookie in your next request to qcSessionEndPoint, it should give you QCSession cookie.
Use both LWSSO_COOKIE_KEY and QCSession cookies in your subsequent requests to get data from ALM.
I see that you are using octet-stream to get the defect response. When I checked the documentation, it can return one of the following types.
"application/xml"
"application/atom+xml"
"application/json"
Just in case, if you need to see some working implementation in python, here it is https://github.com/macroking/ALM-Integration/blob/master/ALM_Integration_Util.py
It may give you some idea.

Thank you #Barney. You sent me in the correct direction :-) For anyone interested, I managed it like this, e.g. for getting defect ID 473:
Logging on to create a CookieContainer and then use that to do the actual ALM data fetch:
private void button1_Click(object sender, EventArgs e)
{
string almURL = #"https://url/qcbin/";
string domain = "domain";
string project = "project";
CookieContainer cookieContainer = LoginAlm2(almURL, "username", "password", domain, project);
HttpWebRequest myWebRequest1 = (HttpWebRequest)WebRequest.Create(almURL + "/rest/domains/" + domain + "/projects/" + project + "/defects/473");
myWebRequest1.CookieContainer = cookieContainer;
myWebRequest1.Accept = "application/json";
WebResponse webResponse1 = myWebRequest1.GetResponse();
StreamReader reader = new StreamReader(webResponse1.GetResponseStream());
string res = reader.ReadToEnd();
}
public CookieContainer LoginAlm2(string server, string user, string password, string domain, string project)
{
//Creating the WebRequest with the URL and encoded authentication
string StrServerLogin = server + "/api/authentication/sign-in";
HttpWebRequest myWebRequest = (HttpWebRequest)WebRequest.Create(StrServerLogin);
myWebRequest.Headers[HttpRequestHeader.Authorization] = "Basic " + Base64Encode(user + ":" + password);
WebResponse webResponse = myWebRequest.GetResponse();
CookieContainer c = new CookieContainer();
Uri uri = new Uri(server);
string StrCookie = webResponse.Headers.ToString();
string StrCookie1 = StrCookie.Substring(StrCookie.IndexOf("LWSSO_COOKIE_KEY=") + 17);
StrCookie1 = StrCookie1.Substring(0, StrCookie1.IndexOf(";"));
c.Add(new Cookie("LWSSO_COOKIE_KEY", StrCookie1) { Domain = uri.Host });
//Then the QCSession cookie
string StrCookie2 = StrCookie.Substring(StrCookie.IndexOf("QCSession=") + 10);
StrCookie2 = StrCookie2.Substring(0, StrCookie2.IndexOf(";"));
c.Add(new Cookie("QCSession", StrCookie2) { Domain = uri.Host });
//Then the ALM_USER cookie
string StrCookie3 = StrCookie.Substring(StrCookie.IndexOf("ALM_USER=") + 9);
StrCookie3 = StrCookie3.Substring(0, StrCookie3.IndexOf(";"));
c.Add(new Cookie("ALM_USER", StrCookie3) { Domain = uri.Host });
//And finally the XSRF-TOKEN cookie
string StrCookie4 = StrCookie.Substring(StrCookie.IndexOf("XSRF-TOKEN=") + 12);
StrCookie4 = StrCookie4.Substring(0, StrCookie4.IndexOf(";"));
c.Add(new Cookie("XSRF-TOKEN", StrCookie4) { Domain = uri.Host });
return c;
}
Works like a charm :-)
