APi call through VS studio Console in c#

the APi call (Patch) through Visual Studio Console app is failing with the following error
The remote server returned an error: (403) Forbidden.
The same call works fine when I use Postman. I get the response back from Postman(Basic authentication with username and password). What could be the issue with the c# program.

NULL JSON posted onto PHP server using HTTP requests from C#

I'm trying to post a JSON string on a PHP page using HTTP response methods as follows:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
using System.Web.Script.Serialization;
using System.Web;
namespace http_requests
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
//var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost/abc/products.php");
//httpWebRequest.ContentType = "application/json";
//httpWebRequest.Method = "POST";
//using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
//{
// string json = new JavaScriptSerializer().Serialize(new
// {
// user = "Foo",
// password = "Baz"
// });
// streamWriter.Write(json);
// streamWriter.Flush();
// streamWriter.Close();
// var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
// using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
// {
// var result = streamReader.ReadToEnd();
// }
//}
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://localhost/ABC/products.php");
request.Method = WebRequestMethods.Http.Post;
string DataToPost = new JavaScriptSerializer().Serialize(new
{
user = "Foo",
password = "Baz"
});
byte[] bytes = Encoding.UTF8.GetBytes(DataToPost);
string byteString = Encoding.UTF8.GetString(bytes);
Stream os = null;
//string postData = "firstName=" + HttpUtility.UrlEncode(p.firstName) +
request.ContentLength = bytes.Length;
request.ContentType = "application/x-www-form-urlencoded";
os = request.GetRequestStream();
os.Write(bytes, 0, bytes.Length);
//StreamWriter writer = new StreamWriter(request.GetRequestStream());
//writer.Write(DataToPost);
//writer.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
//StreamReader reader = new StreamReader(response.GetResponseStream());
using (var streamReader = new StreamReader(response.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
richTextBox1.AppendText("R : " + result);
Console.WriteLine(streamReader.ReadToEnd().Trim());
}
//richTextBox1.Text = response.ToString();
}
}
}
I tried it in many different ways (converting to bytes too) but still posts a NULL array.
PHP Code:
<?php
$json = $_POST;
if (isset($json)) {
echo "This var is set so I will print.";
//var_dump($json);
var_dump(json_decode(file_get_contents('php://input')));
}
?>
When I try to get tha response from server and print onto a text box, it prints right:
R : This var is set so I will print.object(stdClass)#1 (2) {
["user"]=>
string(3) "Foo"
["password"]=>
string(3) "Baz"
}
but i'm unable to check it on my PHP page, it says:
This var is set so I will print.NULL
Not sure if its posting a JSON onto PHP or not, but it sure does posts a NULL.
I want to see the JSON on PHP page, Any help would be appreciated.
Thank you,

There is nothing wrong with your c# client side code, the problem is that visiting a site in your browser is a seperate request from the c# post, so you wont see anything.
As per my comment, if you want to see the data in a browser after a post i c#, you will need to save and retrieve it.
Here is a simple example using a text file to save post data and display it:
//if post request
if($_SERVER['REQUEST_METHOD']=='POST'){
//get data from POST
$data = file_get_contents('php://input');
//save to file
file_put_contents('data.txt', $data);
die('Saved');
}
//else if its a get request (eg view in browser)
var_dump(json_decode(file_get_contents('data.txt')));

ASP.NET C# Get referer from Paypal

I have a big trouble. I've done an e-commerce site many month ago, now i wanna do that after an user has bought, paypal redirect the user in a website that confirm the bought with an e-mail.
Obviously, the return page has a control of refererpage, because it can't send a confirmation mail to all that write the page address, but the command:
Request.ServerVariables["HTTP_REFERER"]
Doesn't work, because paypal is an https webpage. So, how i can solve it?
Thank you before!

hi you can try below code for this:
First set the "notify_url" in your website
<input type="hidden" name="notify_url" value="http://www.your-website-url.com/notifypaypal.aspx" />
after that create notifypaypal.aspx Page.
notifypaypal.aspx : here not required any code ..

so i want to know how can i use this code so that it can send notification to multiple devices.
If anyone knows about this then please provide answer or suggestion for the same.
Thanks in advance

C# site manipulation

I need have some site manipulation from C# programming language (Microsoft Visual Studio 2010). It is site "http://m.vk.com" . I authorized on this site. It was everything normal. First web-page after authorization it was my profile page. But when I passed to another page this site I loosed my authorization. Another site page was displayed but in non authorization mode. I saved and wrote cookies files to another query. I write next my C# programming code:
I used these directives:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
using HtmlAgilityPack;
It is main function code which started after main button pushing:
private void button1_Click(object sender, EventArgs e)
{
string login = textBox1.Text;
string pass = textBox2.Text;
bool avt = http_auth_vk(login, pass);
if (avt == true)
{
toolStripStatusLabel1.Text = "Succes authorization !";
}
else
{
toolStripStatusLabel1.Text = "Authorization data incorrect !";
}
}
This is the function "http_auth_vk" :
public bool http_auth_vk(string login, string pass)
{
//*****************************
//Получаем action_url
//*****************************
System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
System.Net.WebRequest reqGET = System.Net.WebRequest.Create("http://m.vk.com/");
System.Net.WebResponse resp = reqGET.GetResponse();
System.IO.Stream stream = resp.GetResponseStream();
System.IO.StreamReader sr = new System.IO.StreamReader(stream);
string s = sr.ReadToEnd();
//*****************************
//Парсим
//*****************************
// Создаём экземпляр класса
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
// Загружаем в класс (парсер) наш html
doc.LoadHtml(s);
// Извлекаем значения
HtmlNode bodyNode = doc.DocumentNode.SelectSingleNode("//div[#class='cont']/form");
// Выводим на экран значиение атрибута src
// у изображения, которое находилось
// в теге <div> в слассом bla
string result1 = bodyNode.Attributes["action"].Value;

using (var requestStream = request.GetRequestStream())
using (var writer = new StreamWriter(requestStream))
{
writer.Write("email=" + login + "&pass=" + pass);
}
using (var responseStream = request.GetResponse().GetResponseStream())
using (var reader = new StreamReader(responseStream))
{
var result = reader.ReadToEnd();
//*****************************

result2 = bodyNode2.Attributes["href"].Value.Substring(3);
//Если ID найден, то авторизация удалась
//ПЕРЕХОД НА СТРАНИЦУ ГРУППЫ
//string sLocation = myHttpWebResponse.Headers["Location"];
// получам cookie
string sCookies = "";
if (!String.IsNullOrEmpty(resp.Headers["Set-Cookie"]))
{
sCookies = resp.Headers["Set-Cookie"];
}
MessageBox.Show(sCookies);
// формируем запрос
HttpWebRequest myHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create("http://m.vk.com/id100669061");
//myHttpWebRequest.Proxy = new WebProxy("127.0.0.1", 8888);

How I can save authorization, after next page pass?

After a little investigation I believe I found your problem. The .NET framework will take care the cookies for you, you don't need to worry about setting the cookie or save the cookie for later use, but you do need to use the same CookieContainer for all requests.
So first set the cookie container you would like to use:
var cookies = new CookieContainer();
You can remove this, as well, all piece of code that uses sCookies.
string sCookies = "";
if (!String.IsNullOrEmpty(resp.Headers["Set-Cookie"]))
{
sCookies = resp.Headers["Set-Cookie"];
}
MessageBox.Show(sCookies);
And in the second/third request instead of having this:
if (!String.IsNullOrEmpty(sCookies))
{
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, sCookies);
}
You need to have this (CookieContainer)
myHttpWebRequest.CookieContainer = cookies;
