Why can't I call web service method like that:
ws test = new ws();
test.Credentials = new NetworkCredential("UserName", "Password");
var temp = test.Method(1, "test");`
But this work:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("url");
req.Credentials = new NetworkCredential("UserName", "Password");
using (WebResponse response = req.GetResponse())
{
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
string result= reader.ReadToEnd();
}
}
Web service use https.
I get this error:
System.Net.WebException: The request failed with HTTP status 403: Forbidden.

My code is sending a HTTP POST request with a JSON body. It is working
as expected in localhost but when I deploy it on server then it is
working differently. On my local machine response is okey but on server the response says request is not same !
var request = WebRequest.Create($"{baseUrl}{resourceAddress}");
request.Method = "POST";
request.ContentType = "application/json";
var json = JsonConvert.SerializeObject(requestBody);
request.ContentLength = json.Length;
using (var webStream = request.GetRequestStream())
{
using (var requestWriter = new StreamWriter(webStream, Encoding.ASCII))
{
requestWriter.Write(json);
}
}
try
{
var webResponse = request.GetResponse();
using var webStream = webResponse.GetResponseStream() ?? Stream.Null;
using var responseReader = new StreamReader(webStream);
var response = responseReader.ReadToEnd();
var paymentUrlResponse = JsonConvert.DeserializeObject<PaymentUrlResponse>(response);
if(paymentUrlResponse.Result.ResultCode != "00")
{
throw new Exception("Failed to get URL. Http Response: OK , Result Code: " + paymentUrlResponse.Result.ResultCode);
}
_httpContextAccessor.HttpContext.Response.Redirect(redirectionUrl);
}
I am using C# to call OneSignal Create Notifications API. Its working from my home but when i try to send it from my office, it gives a 400 BAD REQUEST.
The error that i get is
The error that comes is Please include a case-sensitive header of
Authorization: Basic <YOUR-REST-API-KEY-HERE> with a valid REST API key."],
"reference":["https://documentation.onesignal.com/docs/accounts-and-keys#section-keys-ids"]
Also, in office network, when i send it from OneSignal Dashboard it works.
Is it a firewall issue?
Tested with POSTMAN and got the same results. POSTMAN working outside office network and giving 400 Bad Request inside office network.
using System.IO;
using System.Net;
using System.Text;
var request = WebRequest.Create("https://onesignal.com/api/v1/notifications") as HttpWebRequest;
request.KeepAlive = true;
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
request.Headers.Add("authorization", "Basic NGEwMGZmMjItY2NkNy0xMWUzLTk5ZDUtMDAwYzI5NDBlNjxx");
var serializer = new JavaScriptSerializer();
var obj = new { app_id = "5eb5a37e-b458-11e3-ac11-000c2940e6xx",
contents = new { en = "English Message" },
include_player_ids = new string[] {"all"} };
var param = serializer.Serialize(obj);
byte[] byteArray = Encoding.UTF8.GetBytes(param);
string responseContent = null;
try {
using (var writer = request.GetRequestStream()) {
writer.Write(byteArray, 0, byteArray.Length);
}
using (var response = request.GetResponse() as HttpWebResponse) {
using (var reader = new StreamReader(response.GetResponseStream())) {
responseContent = reader.ReadToEnd();
}
}
}
catch (WebException ex) {
System.Diagnostics.Debug.WriteLine(ex.Message);
System.Diagnostics.Debug.WriteLine(new StreamReader(ex.Response.GetResponseStream()).ReadToEnd());

try following
System.Net.CredentialCache credentialCache = new System.Net.CredentialCache();
credentialCache.Add(
new System.Uri("http://www.yoururl.com/"),
"Basic",
new System.Net.NetworkCredential("username", "password")
);
...
...
httpWebRequest.Credentials = credentialCache;
but i think you should use test RESTFUL tools to check what parameters can return correct value at all first.
The issue is solved by adding the onesignal host to our firewall as a trusted site.
I am making a call to a page on my site using webclient. I'm trying to get the result of the webpage put into a pdf so I am trying to get a string representation of the rendered page. The problem is that the request is not authenticated so all I get is a login screen. I have sent the UseDefaultCredentials property to true but I still get the same result. Below is a portion of my code:
WebClient webClient = new WebClient();
webClient.Encoding = Encoding.UTF8;
webClient.UseDefaultCredentials = true;
return Encoding.UTF8.GetString(webClient.UploadValues(link, "POST",form));
You need to give the WebClient object the credentials. Something like this...
WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password");
What kind of authentication are you using? If it's Forms authentication, then at best, you'll have to find the .ASPXAUTH cookie and pass it in the WebClient request.
At worst, it won't work.
Public Function getWeb(ByRef sURL As String) As String
Dim myWebClient As New System.Net.WebClient()
Try
Dim myCredentialCache As New System.Net.CredentialCache()
Dim myURI As New Uri(sURL)
myCredentialCache.Add(myURI, "ntlm", System.Net.CredentialCache.DefaultNetworkCredentials)
myWebClient.Encoding = System.Text.Encoding.UTF8
myWebClient.Credentials = myCredentialCache
Return myWebClient.DownloadString(myURI)
Catch ex As Exception
Return "Exception " & ex.ToString()
End Try
End Function
This helped me to call API that was using cookie authentication. I have passed authorization in header like this:
request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
complete code:
// utility method to read the cookie value:
public static string ReadCookie(string cookieName)
{
var cookies = HttpContext.Current.Request.Cookies;
var cookie = cookies.Get(cookieName);
if (cookie != null)
return cookie.Value;
return null;
}
// using statements where you are creating your webclient
using System.Web.Script.Serialization;
using System.Net;
using System.IO;
// WebClient:
var requestUrl = "<API_url>";
var postRequest = new ClassRoom { name = "kushal seth" };
using (var webClient = new WebClient()) {
JavaScriptSerializer serializer = new JavaScriptSerializer();
byte[] requestData = Encoding.ASCII.GetBytes(serializer.Serialize(postRequest));
HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = requestData.Length;
request.ContentType = "application/json";
request.Expect = "application/json";
request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
request.GetRequestStream().Write(requestData, 0, requestData.Length);
using (var response = (HttpWebResponse)request.GetResponse()) {
var reader = new StreamReader(response.GetResponseStream());
var objText = reader.ReadToEnd(); // objText will have the value
}
}

This code is working on win7 and LAN
and on win8 and any of wireless connection
but doesn't work on win8 and LAN error: 407 Proxy authentication required.
Is there any solution.
Thanks.
try with adding proxy credentials to request and also give network credentials
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/");
request.Credentials = new NetworkCredential("username", "pw");
WebProxy webProxy = new WebProxy("http://myproxy.net:8080/", true)
{
Credentials = new NetworkCredential("username", "pw"),
UseDefaultCredentials = false
};
request.Proxy = webProxy;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
//rest of the code...
Edit
For requests that you create, you can disable automatic proxy detection at the request level by using a null Proxy with your request
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/");
request.Proxy = null;
//rest of the code
WebProxy webProxy = new WebProxy("http://myproxy.net:8080/", true)
{
UseDefaultCredentials = false,
Credentials = new NetworkCredential("username", "pw")
};
Please note Correct sequence to set property {other wise failed for me}
