Read api result in asp.net

I am using the below C#/ASP.net code to get the weather data from the api. The api link works if I copy/paste it on the browser, returns all the data I want .
But in my C# code, I get error "{"Unable to connect to the remote server"}"
Anyone knows what is wrong?

I'm not sure why you getting unable to connect remote server may be turning off your firewall solve your problem. try below code. https://stackoverflow.com/a/16642279/2745294
https://stackoverflow.com/a/5566981/2745294
string urlAddress = "http://api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID=e67fab67a2bc61c221e8a6165965c107";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddress);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream receiveStream = response.GetResponseStream();
StreamReader readStream = null;
if (response.CharacterSet == null)
{
readStream = new StreamReader(receiveStream);
}
else
{
readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
}
string data = readStream.ReadToEnd();
response.Close();
readStream.Close();
}

I noticed the issue was that my internet connection was using an internal dns server which its setting does not allow such a calls due to security restrictions. Outside our office, the code works just fine.

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 ..
notifypaypal.aspx.cs :

//Post back to either sandbox or live
// string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";//For localhost
string strLive = "https://www.paypal.com/cgi-bin/webscr";//For live server
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strLive);
//Set values for the request back
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
string ipnPost = strRequest;
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//for proxy
//WebProxy proxy = new WebProxy(new Uri("http://url:port#"));
//req.Proxy = proxy;
//Send the request to PayPal and get the response
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
// logging ipn messages... be sure that you give write permission to process executing this code
string logPathDir = ResolveUrl("Messages");
string logPath = string.Format("{0}\\{1}.txt",Server.MapPath(logPathDir), DateTime.Now.Ticks);

Get userstream from twitter

A month ago a build a twitter tool in c# Windows Form Application. I can send tweets and view the hometimeline,friendtimeline and the mentiontimeline. I used the twitterizer dll with the OAuthTokens method, but there is a refresh limit and it is very slow.
Now i want to start a streaming twitter application but i cant find a proper example or documentation for this. I started but i didn't find the function who can start the stream and but it in a string or textbox. My question is how to get the stream from the hometimeline.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Twitterizer;
using Twitterizer.Streaming;
namespace Twww
{
public partial class Form1 : Form
{
public OAuthTokens tokens = new OAuthTokens();
private string userAgent = null;
public Form1()
{
InitializeComponent();
/* input tokens removed in example code */
tokens.AccessToken = accessToken;
tokens.AccessTokenSecret = accesssecret;
tokens.ConsumerKey = consumerKey;
tokens.ConsumerSecret = consumerSecret;
}
private void Form1_Load(object sender, EventArgs e)
{
Twitterizer.Streaming.UserStreamOptions options = new UserStreamOptions();
OAuthTokens token = new Twitterizer.OAuthTokens ();
TwitterStream stream = new TwitterStream(token, userAgent, options);
}
}
}
I tried to make it work for a user stream, but i get 401 or 403 errors, who says i have no rights
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using Twitterizer;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
OAuthTokens tokens = new OAuthTokens();
string consumerKey = "XX";
string consumerSecret = "XX";
string accessToken = "XX";
string accesssecret = "XX";
tokens.AccessToken = accessToken;
tokens.AccessTokenSecret = accesssecret;
tokens.ConsumerKey = consumerKey;
tokens.ConsumerSecret = consumerSecret;
string url = "https://userstream.twitter.com/1.1/user.json?with=followings&replies=all";
WebClient wc = new WebClient();
wc.Credentials = new NetworkCredential("XX", "XX");
StreamReader reader = new StreamReader(wc.OpenRead(url));
string line;
while ((line = reader.ReadLine()) != null)
{
dynamic json = JsonConvert.DeserializeObject(line);
if (json.text != null)
{
Console.WriteLine(json.text);
}
}
}
}
}

Check this, you have a very well designed guide of TwitterStream in twitterizer:

Cannot set CookieContainer due to the state of the HttpWebRequest object error?

I am currently trying to login and get cookies to a remote server using windows phone 7 silverlight in visual studio. I managed to login and get a successful result for login, but when I try to put in the codes to get cookies, it just failed.
It produced error "Cannot set CookieContainer due to the state of the HttpWebRequest object." on my code "request.CookieContainer = new CookieContainer();"
Can anyone helps me? I can't seem to find the error and I try to look at the documentation and examples but with no luck. Below is my full codes on windows phone 7.

isf.OpenFile("CookieExCookies", FileMode.Open))
{
using (StreamReader sr = new StreamReader(isfs))
{
textBoxCookies.Text = sr.ReadToEnd();
sr.Close();
}
}
}
}
}
}

Move the line:-
request.CookieContainer = new CookieContainer();
out of RequestReady and put it in buttonLogin_Click just after you have constructed it.
OR since you aren't re-using it anywhere ditch line altogether.
OR if in fact for things to really work you need to re-use it then construct and hold it somewhere else (such as a field in the class) and assign it to each Request object created before you invoke any BeginGetRequestStream or BeginGetResponse.

Remove the ; from the parameter names in the query string.
