I am trying to access the data on a website using some C# code. From a browser, a user would go to http://www.hkexnews.hk/sdw/search/search_sdw.asp, put in a date (17 May 2016) and a stock code ("00001") and be taken to a table with the relevant data.
I have used a Firefox add-on (LiveHTTPHeaders) to see that this process produces the following POST request:

// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Console.WriteLine(responseFromServer);

reader.Close();
dataStream.Close();
response.Close();
What this code appears to do is simply spit out the Html of the original search screen instead of taking me to the results.
Edit: I also tried doing the same with the HttpClient class, as below:
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://www.hkexnews.hk/sdw/search/search_sdw.asp");
var content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("txt_today_d", "20"),
new KeyValuePair<string, string>("txt_today_m", "5"),
new KeyValuePair<string, string>("txt_today_y", "2016"),
new KeyValuePair<string, string>("current_page", "1"),
new KeyValuePair<string, string>("stock_market", "HKEX"),
new KeyValuePair<string, string>("IsExist_Slt_Stock_Id", "False"),
new KeyValuePair<string, string>("IsExist_Slt_Part_Id", "False"),
new KeyValuePair<string, string>("rdo_SelectSortBy", "Shareholding"),
new KeyValuePair<string, string>("sessionToken", "1458.568"),
new KeyValuePair<string, string>("sel_ShareholdingDate_d", "17"),
new KeyValuePair<string, string>("sel_ShareholdingDate_m", "05"),
new KeyValuePair<string, string>("sel_ShareholdingDate_y", "2016"),
new KeyValuePair<string, string>("txt_stock_code", "00001"),
new KeyValuePair<string, string>("txt_stock_name", ""),
new KeyValuePair<string, string>("txt_ParticipantID", ""),
new KeyValuePair<string, string>("txt_Participant_name", "")
});
var result = client.PostAsync("/sdw/search/search_sdw.asp", content).Result;
string resultContent = result.Content.ReadAsStringAsync().Result;
Console.WriteLine(resultContent);
This produces the same result (Html of original form)
Because something wrong in your request(maybe cookie is not correct) and your request was redirected to original website.

Alright! So I have this Restful call that i am trying to make to a Polycom device.
To sort of isolate within this code I used RestSharp and it works fine. Also removing the credentials object or altering it makes it kick back an unauthorized so i believe authorization is fine. I think its the body/parameters that are incorrect.
//THIS SECTION WORKS
//RestRequest restRequest = new RestRequest();
//restRequest.AddJsonBody(body);
//RestClient restClient = new RestClient(targetUrl);
//restClient.RemoteCertificateValidationCallback = (sPoint, cert, wRequest, certProb) => true;
//restClient.Authenticator = new HttpBasicAuthenticator(username, deskPhone.MACPassword);
//IRestResponse restsharpResponse = await restClient.ExecutePostAsync(restRequest).ConfigureAwait(false);
//END SECTION
What my issue is.. I have no idea why I am getting an error 400 Bad Request. When I look at what I have in the call it all seems to align correctly. The Auth token is the same as RestSharp and the body is the same object.
I really am at a loss for what i can do and unfortunately I cant use restsharp i need to use what is available in Net Core.
I have a few different implementations in the code as you can see below. I attempted with HttpClient and I attempted with HttpWebRequest.
My question is... What likely bug do i have that is preventing this from being a proper request.
This link here is to API documentation which I also seem to be aligning with correctly.
https://support.polycom.com/content/dam/polycom-support/products/voice/polycom-uc/other-documents/en/2018/ucsoftware-restapi.pdf

request.ContentType = "application/json; charset=utf-8";
request.Method = "POST";
request.Headers.Add("Authorization", "Basic " + encoded);
request.AuthenticationLevel = System.Net.Security.AuthenticationLevel.None;
request.Accept = "application/json";
using (StreamWriter streamWriter = new StreamWriter(request.GetRequestStream()))
{

}
HttpWebResponse httpResponse = (HttpWebResponse)request.GetResponse();

}
HttpClient httpClient = new HttpClient(handler);
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
StringContent temp = new StringContent(body, Encoding.UTF8, "application/json");
HttpRequestMessage httpMessage = new HttpRequestMessage(HttpMethod.Post, targetUrl);
httpMessage.Content = temp;
HttpResponseMessage testA = await httpClient.SendAsync(httpMessage).ConfigureAwait(false);
HttpResponseMessage stuff = await httpClient.PostAsync(targetUrl, temp).ConfigureAwait(false);
handler.Dispose();
httpMessage.Dispose();
httpClient.Dispose();
}
So below are the two comparisons from fiddler.
The problem child is this line here.
request.ContentType = "application/json; charset=utf-8";
The fix??
request.ContentType = "application/json";
The following below is the fiddler results that led to the discovery.

Console.ReadKey();
in the file odm.html I m checking if the html code contain "My account" that shown when the user is actually logged in .
but this doesnt seems to be working for some reasons that i still don't know .
i made some research to about HTTP status code but in my brup suit after trying to login in with an actual exisiting account and a none valid account it gives the same http code 302 with a different Content Length .
EDIT:
the issue is i don't find 'my account' in the html file , i only find the page where the user is going to login
You are trying to send request body in query string, you are setting the request method as POST but you are not sending the body. The request url should be:
https://account.ankama.com/sso
And you need to set request body before sending the request:
var bytes = Encoding.UTF8.GetBytes("action=login&from=http%3A%2F%2Fwww.dofus.com%2Ffr&login=user123&password=password1232F&remember=1");
request.ContentLength = bytes.Length;
using (var stream = request.GetRequestStream())
{
stream.Write(bytes, 0, bytes.Length);
}
So I'm writing the client side user authentication code for my Web API ReST service.
This is how the request and response should look like and I've written this code to register a user and it works fine.
Http Request:
POST https://localhost:44305/api/Account/Register HTTP/1.1
Host: localhost:44305
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0
Accept: */*
Content-Type: application/json; charset=utf-8
X-Requested-With: XMLHttpRequest
Referer: https://localhost:44305/
Content-Length: 84
{"Email":"alice#example.com","Password":"Password1!","ConfirmPassword":"Password1!"}
Http Response:
HTTP/1.1 200 OK
Server: Microsoft-IIS/8.0
Date: Wed, 01 Oct 2014 00:57:58 GMT
Content-Length: 0
Code to accomplish this:
byte[] data = Encoding.UTF8.GetBytes("{\"Email\":\"alssice#example.com\"," + "\"Password\":\"Password1!\"," + "\"ConfirmPassword\":\"Password1!\"}");
WebRequest request = WebRequest.Create("http://localhost:8091/api/Account/Register");
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
request.ContentLength = data.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
string responseContent = null;
using (WebResponse response = request.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
using (StreamReader sr99 = new StreamReader(stream))
{
responseContent = sr99.ReadToEnd();
}
}
}
Console.WriteLine(responseContent);
This works fine and the user account is created in the database but I don't get the response.
The next problem is sending sending the login details to get a bearer token? How can I do this?
This is what the request and response should look like
HTTP REQUEST FOR AUTHENTICATION:
POST https://localhost:44305/Token HTTP/1.1
Host: localhost:44305
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0
Accept: */*

X-Requested-With: XMLHttpRequest

HTTP RESPONSE FOR AUTHENTICATION:
HTTP/1.1 200 OK
Content-Length: 669
Content-Type: application/json;charset=UTF-8
Server: Microsoft-IIS/8.0
Date: Wed, 01 Oct 2014 01:22:36 GMT
{
"access_token":"imSXTs2OqSrGWzsFQhIXziFCO3rF...",
"token_type":"bearer",
"expires_in":1209599,
"userName":"alice#example.com",
".issued":"Wed, 01 Oct 2014 01:22:33 GMT",
".expires":"Wed, 15 Oct 2014 01:22:33 GMT"
}
SO how can I send a request for a token?
I'd kindly like to suggest you using HttpClient if you're going for your own http rest client in your app.
Solution using HttpClient and Json.net:
public class TokenResponse
{
public string access_token { get; set; }
public string token_type { get; set; }
public int expires_in { get; set; }
public string userName { get; set; }
public string issued { get; set; }
public string expires { get; set; }
}
private async Task Login()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://localhost:44305");
var content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("grant_type", "password"),
new KeyValuePair<string, string>("username", "alice#example.com"),
new KeyValuePair<string, string>("password", "password1")
});
var result = await client.PostAsync("/token", content);
string resultContent = await result.Content.ReadAsStringAsync();
var tokenResponse = JsonConvert.DeserializeObject<TokenResponse>(resultContent);
}
}
And if you need to use HttpWebRequest:
If this is the case, your solution might look something like the following.
private void Login()
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://localhost:44305/Token");
request.Method = "POST";
request.AllowAutoRedirect = false;
request.Accept = "*/*";
request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
StringBuilder postData = new StringBuilder();
postData.Append("grant_type=" + HttpUtility.UrlEncode("password") + "&");
postData.Append("username=" + HttpUtility.UrlEncode("alice#example.com") + "&");
postData.Append("password=" + HttpUtility.UrlEncode("password"));
using (StreamWriter stOut = new StreamWriter(request.GetRequestStream(), Encoding.UTF8))
{
stOut.Write(postData);
stOut.Close();
}
}
Update
Now Im not sure where and how you are trying this. If you're invoking this from a console application main method, make sure the following so you don't have to come back to the same asynchronous context and this should always be invoked from an async method itself:
var result = await client.PostAsync("https://localhost:44305/token", content).ConfigureAwait(false);
I updated my solution in a github gist. It's working for me as it's trying to post the request right away.
when i send post data to the proxy server - it returns an error:
Invalid Request error was encountered while trying to process the request:
Some possible problems are:
Missing or unknown
request method. Missing URL. Missing HTTP Identifier
(HTTP/1.0). Request is too large. Content-Length missing for
POST or PUT requests. Illegal character in hostname; underscores
are not allowed. HTTP/1.1 Expect: feature is being asked from an
HTTP/1.0 software.
and headers:

Set proxy in programm:
request = (HttpWebRequest)HttpWebRequest.Create(postUrl);
request.Proxy = new WebProxy( this.ip + ":" + this.port);
request.UseDefaultCredentials = true;
Sending request:
try
{
System.Net.ServicePointManager.Expect100Continue = false;
Stream dataStream = request.GetRequestStream();
dataStream.Write(data, 0, data.Length);
dataStream.Close();
WebResponse response = request.GetResponse();
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
reader.Close();
dataStream.Close();
response.Close();
}
catch (WebException ex)
{
Console.WriteLine(ex.Status);
if (ex.Response != null)
{
if (ex.Response.ContentLength != 0)
{
using (var stream = ex.Response.GetResponseStream())
{
using (var reader = new StreamReader(stream))
{
Console.WriteLine(reader.ReadToEnd());
}
}
}
}
}
When the proxy server is disabled or commented out code send post data - request succeeds
//Stream dataStream = request.GetRequestStream();
//dataStream.Write(data, 0, data.Length);
//dataStream.Close();
Thanks for answers !
The remark about missing HTTP identifier, does
request.Proxy = new WebProxy("http://" + this.ip + ":" + this.port);
make any difference?
I am trying to log in to a website using Visual C# but I am not sure where to start. Eventually, I want to download a PDF File from the website but I must login to the website as it is password-restricted. The url is below:

I am not sure if it is working. What are my options, and is the code even doing anything?
Here is my code so far. (Note: I do not want to browse the web in the Visual C# App, I want it done in the background)

webRequest.CookieContainer = _jar;
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";

Couple things which can help you
(a) this url also works without SSL (so you will not have a deal with check the right certificate, etc), and for now you can just try to do this work with url http://sso.greatclips.com/authentication/login/login.aspx?ud=1&ApplicationCode=1&ReturnURL=https%3A%2F%2Fwww.salondata.com%2Fv2%2Fwa%2FloginPostBack (http instead of https)
(b) use fiddler tool which allows you to logs the traffic between browser and web server. Just take a look on request which browser sends to server when you click on Sign In button and try to implement the same request in C# code.
