Issue After upgrading Restsharp version

Can someone please help on this issue, i gets hang and no error is coming.
Seems like ends up with some unknow issue.
I am attaching my code before and after upgrading the restsharp library.
Code in Rest sharp version 106.12.00
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using RestSharp;
namespace ConsoleApp5
{
class Program
{
static void Main(string[] args)
{
var client = new RestClient("https://shoonyatrade.finvasia.com/NorenWClientTP/QuickAuth");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Content-Type", "text/plain");
var body = #"jData={""apkversion"":""1.0.0"",""uid"":""123456""}";
request.AddParameter("text/plain", body, ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
}
}
}
Code after upgrading to 108.0.1
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using RestSharp;
namespace ConsoleApp5
{
class Program
{
static void Main(string[] args)
{
var client = new RestClient("https://shoonyatrade.finvasia.com/NorenWClientTP/QuickAuth");
client.Options.MaxTimeout = -1;
var request = new RestRequest("",Method.Post);
request.AddHeader("Content-Type", "text/plain");
var body = #"jData={""apkversion"":""1.0.0"",""uid"":""123456""}";
request.AddParameter("text/plain", body, ParameterType.RequestBody);
RestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
}
}
}
Expected Response
{"stat":"Not_Ok","emsg":"Invalid Input : uid or pwd or factor2 or imei or apkversion or vc or appkey or source is Missing."}

The docs clearly say that you should not use AddParameter with content-type as the parameter name. It won't work.
Use AddStringBody as described in the docs.
request.AddStringBody(body, "text/plain);
You would spend way less time figuring out what's wrong by sending requests to something like requestbin.com and analysing the actual content of it.

Adding this line solved my issue
System.Net.ServicePointManager.Expect100Continue = false;
I have used fiddler to understand what actual request is going on web.
using RestSharp;
using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp5
{
class Program
{
static async Task Main(string[] args)
{
System.Net.ServicePointManager.Expect100Continue = false;
var client = new RestClient("https://shoonyatrade.finvasia.com/NorenWClientTP/QuickAuth");
var request = new RestRequest("",Method.Post);
var body = #"jData={""apkversion"":""1.0.0"",""uid"":""123456""}";
request.AddParameter("text/plain", body, ParameterType.RequestBody);
RestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
}
}
}

How to add 2 authentication headers in a HTTP request using C# .NET Framework

So this is just a simple example that just pulls in the google homepage information. But what I would like to do is get data from a rest API using HttpClient in C# .NET Framework but the issue is I couldn't figure out how to add in 2 authentication headers, the two parameters should be for like a API-Key and an API-Secret-Key. Here is the code I have right now.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Reporting
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnSubmit_Click(object sender, EventArgs e)
{
string StartDate = dtpStartDate.Text;
string EndDate = dtpEndDate.Text;
Main();
async Task Main()
{
try
{
var client = new HttpClient();
// Call asynchronous network methods in a try/catch block to handle exceptions.
HttpResponseMessage response = await client.GetAsync("https://www.google.com");
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
// Above three lines can be replaced with new helper method below
// string responseBody = await client.GetStringAsync(uri);
label1.Text = responseBody;
}
catch (Exception ex)
{
label2.Text = ex.ToString();
//throw ex;
}
}
}
}
}

Can you try the following, please
client.DefaultRequestHeaders.Add("API-Key", "");
client.DefaultRequestHeaders.Add("API-Secret-Key", "");
Note that this does add the headers for the lifetime of the HttpClient

C# Login to a non-interactive website and pass XML via URL

Okay, so here is what I have and I am probably doing this completely wrong, but I need some more direction than what I am finding online.
I am trying to pass a URL containing login information and then pass another url in the same connection containing my XML. That's all, and I can't seem to get this to work. Please help!!
Here's my code.
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Xml;
using System.Net;
using System.IO;
using System.Configuration;
using System.Data.SqlClient;
using System.Data.Sql;
using System.Data;
using System.ComponentModel;
using System.Collections.Specialized;
namespace DataIntegration.DataSender
{
class RaveDataSender
{
static void Main(string[] args)
{
System.Uri myUri = new System.Uri(#"https://api.myloginpage.com/edc_studyservices.jsp?action=importfile&filecontents=<?xml version='1.0'?><dataprocessitems><item>someitem</item></dataprocessitems>&filename=1.xml");
System.Uri loginUri = new System.Uri(#"https://api.myloginpage.com/login.jsp?studyid=something&action=login&login=myLoginName&password=myPassword");
byte[] mybytes = Encoding.ASCII.GetBytes("https://api.myloginpage.com/edc_studyservices.jsp?action=importfile&filecontents=<?xml version='1.0'?><dataprocessitems><item>someitem</item></dataprocessitems>&filename=1.xml");
byte[] loginbytes = Encoding.ASCII.GetBytes(#"https://api.myloginpage.com/login.jsp?studyid=something&action=login&login=myLoginName&password=myPassword");
CookieAwareWebClient client = new CookieAwareWebClient();
client.UploadDataAsync(loginUri, loginbytes);
client.UploadDataAsync(myUri, mybytes);
client.Dispose();
}
public class CookieAwareWebClient : WebClient
{
private CookieContainer cookie = new CookieContainer();
protected override WebRequest GetWebRequest(Uri address)
{
WebRequest request = base.GetWebRequest(address);
if (request is HttpWebRequest)
{
(request as HttpWebRequest).CookieContainer = cookie;
}
return request;
}
}
}
}
EDIT this is what I ended up doing.
using (var client = new CookieAwareWebClient())
{
byte[] authresp = client.UploadData(loginUri, loginbytes);
byte[] dataRespose = client.UploadData(xmlUri, reqbytes);
string authResult = System.Text.Encoding.UTF8.GetString(authresp);
string result = System.Text.Encoding.UTF8.GetString(dataRespose);
client.Dispose();
}

I think the problem might be that you dispose the object while the asynchronous methods still running.

'HttpWebRequest' does not contain a definition for 'GetResponseAsync'

I am new in xamarin and visual studio,I have followed this tuto from microsoft:
enter link description here
to create a cross platform application,but I get this error:
'HttpWebRequest' does not contain a definition for 'GetResponseAsync' and no extension method 'GetResponseAsync' accepting a first argument of type 'HttpWebRequest' was found (a using directive or an assembly reference is it missing * ?)
and this is my code in which I get this error:DataService.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.IO;
using Newtonsoft.Json;
namespace shared
{
//This code shows one way to process JSON data from a service
public class DataService
{
public static async Task<dynamic> getDataFromService(string queryString)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(queryString);
var response = await request.GetResponseAsync().ConfigureAwait(false);
var stream = response.GetResponseStream();
var streamReader = new StreamReader(stream);
string responseText = streamReader.ReadToEnd();
dynamic data = JsonConvert.DeserializeObject(responseText);
return data;
}
}
}
Please how can I solve it, I checked the HttpWebRequest documentation but I didn't get well the problem
thanks for help

Not sure about HttpWebRequest - but a newer and now recommended way to get data is the following:
public static async Task<dynamic> getDataFromService(string queryString)
{
using (var client = new HttpClient())
{
var responseText = await client.GetStringAsync(queryString);
dynamic data = JsonConvert.DeserializeObject(responseText);
return data;
}
}
Try that and let me know if it works.

c# sending data to php url

okay so I have a c# console source code I have created but it does not work how I want it to.
I need to post data to a URL the same as if I was going to input it an a browser.
url with data = localhost/test.php?DGURL=DGURL&DGUSER=DGUSER&DGPASS=DGPASS
Here is my c# script that does not do it the way I want to I want it to post the data as if I had typed it like above.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.Specialized;
using System.Net;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string URL = "http://localhost/test.php";
WebClient webClient = new WebClient();
NameValueCollection formData = new NameValueCollection();
formData["DGURL"] = "DGURL";
formData["DGUSER"] = "DGUSER";
formData["DGPASS"] = "DGPASS";
byte[] responseBytes = webClient.UploadValues(URL, "POST", formData);
string responsefromserver = Encoding.UTF8.GetString(responseBytes);
Console.WriteLine(responsefromserver);
webClient.Dispose();
}
}
}
I have also triead another method in c# this does now work either
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.Specialized;
using System.Net;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string URI = "http://localhost/test.php";
string myParameters = "DGURL=value1&DGUSER=value2&DGPASS=value3";
using (WebClient wc = new WebClient())
{
wc.Headers[HttpRequestHeader.ContentType] = "text/html";
string HtmlResult = wc.UploadString(URI, myParameters);
System.Threading.Thread.Sleep(500000000);
}
}
}
}
I have been trying to figure a way to do this in my c# console for days now

Since what you seem to want is a GET-request with querystrings and not a POST you should do it like this instead.
static void Main(string[] args)
{
var dgurl = "DGURL", user="DGUSER", pass="DGPASS";
var url = string.Format("http://localhost/test.php?DGURL={0}&DGUSER={1}&DGPASS=DGPASS", dgurl, user, pass);
using(var webClient = new WebClient())
{
var response = webClient.DownloadString(url);
Console.WriteLine(response);
}
}
I also wrapped your WebClient in a using-statement so you don't have to worry about disposing it yourself even if it would throw an exception when downloading the string.
Another thing to think about is that you might want to url-encode the parameters in the querystring using WebUtility.UrlEncode to be sure that it doesn't contain invalid chars.

Also note that your parameters will not appear in the URL if you post them. See: https://stackoverflow.com/a/3477374/2832321
