Bot work in local but not in azure

I'm working on a chat bot that help users of a SharePoint on premise network to upload a file. The bot works on local but returns code 500 when tested in Azure.
I'm using Csom library to navigate in the site tree and the SharePoint _api to get all site collections. I have done some test and I don't think that is the Csom that causes this bug, but rather it is the NetworkCredential that doesn't work in Azure.
So can I use credential in Azure ?
I know that the problem comes from this function
public void GetAllSiteCollections(string url)
{
HttpWebRequest endpointRequest = (HttpWebRequest)HttpWebRequest.Create(url + "/_api/search/query?querytext='contentclass:sts_site'&trimduplicates=false&rowlimit=100");
endpointRequest.Method = "GET";
endpointRequest.Accept = "application/json;odata=verbose";
NetworkCredential cred = new NetworkCredential(Login, Mdp, DomaineUser);
endpointRequest.Credentials = cred;
HttpWebResponse endpointResponse = (HttpWebResponse)endpointRequest.GetResponse();
WebResponse webResponse = endpointRequest.GetResponse();
Stream webStream = webResponse.GetResponseStream();
StreamReader responseReader = new StreamReader(webStream);
string response = responseReader.ReadToEnd();
JObject jobj = JObject.Parse(response);
for (int ind = 0; ind < jobj["d"]["query"]["PrimaryQueryResult"]["RelevantResults"]["Table"]["Rows"]["results"].Count(); ind++)
{
string urlCollection = jobj["d"]["query"]["PrimaryQueryResult"]["RelevantResults"]["Table"]["Rows"]["results"][ind]["Cells"]["results"][6]["Value"].ToString();
string nomCollection = jobj["d"]["query"]["PrimaryQueryResult"]["RelevantResults"]["Table"]["Rows"]["results"][ind]["Cells"]["results"][3]["Value"].ToString();
if (urlCollection.Contains("myLocalDomain/sites/") == true)
{
string[] split = urlCollection.Split('/');
ClientCtx = new ClientContext(Domaine + "/sites/" + split[4]);
using (ClientCtx = new ClientContext(ClientCtx.Url))
{
ClientCtx.Credentials = new NetworkCredential(Login, Mdp, DomaineUser);
Web rootWeb = ClientCtx.Site.RootWeb;
ClientCtx.Load(rootWeb);
BasePermissions bp = new BasePermissions();
bp.Set(PermissionKind.AddListItems);
ClientResult<bool> viewListItems = rootWeb.DoesUserHavePermissions(bp);
ClientCtx.ExecuteQuery();
if (viewListItems.Value)
{
ListDesSiteCollections.Add(nomCollection, split[4]);
}
}
}
}
responseReader.Close();
}
When I check the logs at http://botName.azurewebsites.net/api/messages I get the response "The requested resource does not support http method 'GET'"

Unable to call onesignal api within office but working from external wifi

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());
}
System.Diagnostics.Debug.WriteLine(responseContent);

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.

Paypal HTTP post request gives Invalid Merchant or Merchant doesn't exist error in MVC C#

I am facing trouble in making an HTTP post request to Paypal for Secure token to use Paypal's Hosted solution but I am getting this error:
Some required information is missing or incorrect. Please correct the fields below and try again.
Error: Invalid Merchant or Merchant doesn't exist!
This is my C# code throught which I am making HTTP calls:
string strNVP = "https://pilot-payflowpro.paypal.com?PARTNER=PayPal&USER=myUsername&VENDOR=myVendorName&PWD=myPassword&TRXTYPE=A&AMT=" + obj.CurrentPackagePrice + "&CREATESECURETOKEN=Y&SECURETOKENID=" + Guid.NewGuid().ToString("N");
HttpWebRequest wrWebRequest = (HttpWebRequest)WebRequest.Create(strNVP);
wrWebRequest.Method = "POST";
StreamWriter requestWriter = new StreamWriter(wrWebRequest.GetRequestStream());
requestWriter.Write(strNVP);
requestWriter.Close();
HttpWebResponse hwrWebResponse = (HttpWebResponse)wrWebRequest.GetResponse();
StreamReader responseReader = new StreamReader(wrWebRequest.GetResponse().GetResponseStream());
//and read the response
string responseData = responseReader.ReadToEnd();
responseReader.Close();
string result = Server.UrlDecode(responseData);
string[] arrResult = result.Split('&');
Hashtable htResponse = new Hashtable();
string[] responseItemArray;
foreach (string responseItem in arrResult)
{
responseItemArray = responseItem.Split('=');
htResponse.Add(responseItemArray[0], responseItemArray[1]);
}
string responseResult = htResponse["RESULT"].ToString();
string response = htResponse["RESPMSG"].ToString();
///for Success response
if (responseResult == "0" && response == "Approved")
{
ViewBag.secureToken = htResponse["SECURETOKEN"].ToString();
ViewBag.secureTokenId = htResponse["SECURETOKENID"].ToString();
}
Kindly help me in this problem may b I have done some wrong in my code above also.

The issue was that I was unable to receive a Token and TokenID due to that this exception was arising and then I resolved my issue by making modifications in the above code so that the Paypal sends back a response with Token and TokenID which I used in iframe and its working perfect now.
var request = (HttpWebRequest)WebRequest.Create("https://pilot-payflowpro.paypal.com");
var postData = "PARTNER=PayPal&USER=myUser&VENDOR=myVendor&PWD=myPassword&TRXTYPE=A&AMT=50&CREATESECURETOKEN=Y&SECURETOKENID=" + Guid.NewGuid().ToString("N");
var data = Encoding.ASCII.GetBytes(postData);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var responseData = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(responseData.GetResponseStream()).ReadToEnd();
string result = Server.UrlDecode(responseString);
string[] arrResult = result.Split('&');
Hashtable htResponse = new Hashtable();
string[] responseItemArray;
foreach (string responseItem in arrResult)
{
responseItemArray = responseItem.Split('=');
htResponse.Add(responseItemArray[0], responseItemArray[1]);
}
string responseResult = htResponse["RESULT"].ToString();
string response = htResponse["RESPMSG"].ToString();
///for Success response
if (responseResult == "0" && response == "Approved")
{
ViewBag.secureToken = htResponse["SECURETOKEN"].ToString();
ViewBag.secureTokenId = htResponse["SECURETOKENID"].ToString();
}
The above code is buggy and throws exceptions while receiving a response etc. So this code block is working good.

Login to other web site from ASP .NET MVC 5 programmatically with Username & Password

I am working on ASP .Net MVC 5 and want to login programmatically to other web site (server side) and access its source page after log in. I did POST request as shown in below code with "OK" response but the page source always showing that I need to login.
//Code on controller
private static string LoginOn(string url, string email, string password)
{
try
{
var http = WebRequest.Create(url) as HttpWebRequest;
http.KeepAlive = true;
http.Method = "POST";
http.ContentType = "application/x-www-form-urlencoded";
var dataBytes = Encoding.UTF8.GetBytes($"vb_login_username={email}&vb_login_password={password}");
http.ContentLength = dataBytes.Length;
//http.AllowAutoRedirect = false;
using (var postStream = http.GetRequestStream())
{
postStream.Write(dataBytes, 0, dataBytes.Length);
}
var httpResponse = http.GetResponse() as HttpWebResponse;
var source = string.Empty;
using (StreamReader sr = new StreamReader(httpResponse.GetResponseStream()))
{
source = sr.ReadToEnd(); //I debug source here
}
return httpResponse?.ResponseUri.ToString();
//http = WebRequest.Create(httpResponse?.ResponseUri.ToString()) as HttpWebRequest;
//http.CookieContainer = new CookieContainer();
//http.CookieContainer.Add(httpResponse.Cookies);
//HttpWebResponse httpResponse2 = http.GetResponse() as HttpWebResponse;
//using (StreamReader sr = new StreamReader(httpResponse2.GetResponseStream()))
//{
// source = sr.ReadToEnd();
//}
//return httpResponse2?.ResponseUri.ToString();
}
catch (Exception e)
{
Log(e);
}
return null;

oauth/token returns empty body

I am encountering a problem getting the access_token in client application using oauth.
The returned response has empty body though in API I can see the response is not empty.
tokenresponse = {
"access_token":"[ACCESSTOKENVALUE]",
"token_type":"bearer",
"expires_in":"1200",
"refresh_token":"[REFRESHTOKENVALUE]",
"scope":"[SCOPEVALUE]"
}
The method from API that returns the token http://api.sample.com/OAuth/Token:
public ActionResult Token()
{
OutgoingWebResponse response =
this.AuthorizationServer.HandleTokenRequest(this.Request);
string tokenresponse = string.Format("Token({0})", response!=null?response.Body:""));
return response.AsActionResult();
}
The client method that requests the token is:
public string GetAuthorizationToken(string code)
{
string Url = ServerPath + "OAuth/Token";
string redirect_uri_encode = UrlEncode(ClientPath);
string param = string.Format("code={0}&client_id={1}&client_secret={2}&redirect_uri={3}&grant_type=authorization_code",code, ClientId, ClientSecret, redirect_uri_encode);
HttpWebRequest request = HttpWebRequest.Create(Url) as HttpWebRequest;
string result = null;
request.Method = "POST";
request.KeepAlive = true;
request.ContentType = "application/x-www-form-urlencoded";
request.Timeout = 10000;
request.Headers.Remove(HttpRequestHeader.Cookie);
var bs = Encoding.UTF8.GetBytes(param);
using (Stream reqStream = request.GetRequestStream())
{
reqStream.Write(bs, 0, bs.Length);
}
using (WebResponse response = request.GetResponse())
{
var sr = new StreamReader(response.GetResponseStream());
result = sr.ReadToEnd();
sr.Close();
}
if (!string.IsNullOrEmpty(result))
{
TokenData tokendata = JsonConvert.DeserializeObject<TokenData>(result);
return UpdateAuthorizotionFromToken(tokendata);
}
return null;
}
The result variable is empty.
Please let me know if you have any idea what could cause this. Initially I assumed is because of the cookies so I tried to remove them from request.
Thanks in advance.

Dear just create webclient using following code and you will get json info in tokeninfo.I used it and simply its working perfect.
WebClient client = new WebClient();
string postData = "client_id=" + ""
+ "&client_secret=" + ""
+ "&grant_type=password&username=" + "" //your username
+ "&password=" + "";//your password :)
string soundCloudTokenRes = "https://api.soundcloud.com/oauth2/token";
string tokenInfo = client.UploadString(soundCloudTokenRes, postData);
You can then use substring that contains only token from tokeninfo.
To upload tracks on sound cloud.
private void TestSoundCloudupload()
{
System.Net.ServicePointManager.Expect100Continue = false;
var request = WebRequest.Create("https://api.soundcloud.com/tracks") as HttpWebRequest;
//some default headers
request.Accept = "*/*";
request.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3");
request.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
request.Headers.Add("Accept-Language", "en-US,en;q=0.8,ru;q=0.6");
//file array
var files = new UploadFile[] { new UploadFile(Server.MapPath("Downloads//0.mp3"), "track[asset_data]", "application/octet-stream") };
//other form data
var form = new NameValueCollection();
form.Add("track[title]", "Some title");
form.Add("track[sharing]", "public");
form.Add("oauth_token", "");
form.Add("format", "json");
form.Add("Filename", "0.mp3");
form.Add("Upload", "Submit Query");
try
{
using (var response = HttpUploadHelper.Upload(request, files, form))
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
Response.Write(reader.ReadToEnd());
}
}
}
catch (Exception ex)
{
Response.Write(ex.ToString());
}
}
