HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://www.instagram.com/accounts/emailsignup/");
byte[] postBytes = Encoding.ASCII.GetBytes(postData);
req.ContentLength = postBytes.Length;
req.CookieContainer = new CookieContainer();
req.Method = "POST";

Stream dataStream = req.GetRequestStream();
dataStream.Write(postBytes, 0, postBytes.Length);
dataStream.Flush();
dataStream.Close();
HttpWebResponse webResp = (HttpWebResponse)req.GetResponse(); //error in this line---> The remote server returned an error: (403) Forbidden.
Stream datastream = webResp.GetResponseStream();

req.Referer = "";
req.KeepAlive = true;
req.Timeout = 25000;
req.AllowAutoRedirect = false;
CookieContainer cookieJar1 = new CookieContainer();
req.CookieContainer = cookieJar1;
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
foreach (Cookie cookie in res.Cookies)
{
cookieJar1.Add(new Cookie(cookie.Name.Trim(), cookie.Value.Trim(), "/", cookie.Domain));
}
Stream Stream = res.GetResponseStream();
StreamReader reader = new StreamReader(Stream);
string reader_str = reader.ReadToEnd();
HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument();
htmlDoc.LoadHtml(reader_str);
HtmlAgilityPack.HtmlNode node = htmlDoc.DocumentNode.SelectSingleNode("//p[#title='Bitcoin']");
string bitcoin_price_str = node.InnerText.Trim().Replace(",", "");
bitcoin_price = double.Parse(bitcoin_price_str);
reader.Close();
Stream.Close();
res.Close();
The reader_str is like this :

Why reader_str has wrong html?
How can i fix this problem?
I have an application written in C# that use HttpWebRequest to send the request with body.
To add text to request I use this code:
WebRequest webRequest = WebRequest.Create(responseUri);
((HttpWebRequest)webRequest).Referer = responseUri;
((HttpWebRequest)webRequest).Host = "sts.mycompany.com";
((HttpWebRequest)webRequest).KeepAlive = true;
((HttpWebRequest)webRequest).AllowAutoRedirect = true;
((HttpWebRequest)webRequest).UseDefaultCredentials = true;
((HttpWebRequest)webRequest).UserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.84 Safari/537.36";
webRequest.ContentType = "application/x-www-form-urlencoded";
((HttpWebRequest)webRequest).Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
((HttpWebRequest)webRequest).Headers.Add("Cache-Control", "max-age=0");
((HttpWebRequest)webRequest).Headers.Add("Accept-Encoding", "gzip, deflate, br, peerdist");
((HttpWebRequest)webRequest).Headers.Add("Accept-Language", "en-US,en;q=0.5");
//((HttpWebRequest)webRequest).Headers.Add("Accept-Charset", "ISO-8859-2,utf-8;q=0.7,*;q=0.3");
((HttpWebRequest)webRequest).Headers.Add("Upgrade-Insecure-Requests", #"1");
((HttpWebRequest)webRequest).Headers.Add("DNT", #"1");
((HttpWebRequest)webRequest).CookieContainer = CookieContainer;
foreach (var cookie in CookieContainer.GetCookies(new Uri(responseUri)))
{
Console.WriteLine(cookie.ToString());
}
((HttpWebRequest)webRequest).Credentials = GetNetworkCredentials();
((HttpWebRequest)webRequest).AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
webRequest.Method = requestType.ToString();
string msg = String.Format("UserName={0}&Password={1}&AuthMethod=FormsAuthentication", System.Net.WebUtility.UrlEncode(username), System.Net.WebUtility.UrlEncode(password));
webRequest.ContentLength = msg.Length;
Stream reqStream = webRequest.GetRequestStream();
byte[] msgb = System.Text.Encoding.UTF8.GetBytes(msg);
reqStream.Write(msgb, 0, msgb.Length);
reqStream.Close();
var response = (HttpWebResponse)webRequest.GetResponse();
StreamReader sr = new StreamReader(response.GetResponseStream());
string Result = sr.ReadToEnd();
var originalString = response.ResponseUri.OriginalString;
response.Close();
The error is in this line, when I want to add text to body:
byte[] msgb = System.Text.Encoding.UTF8.GetBytes(msg);
reqStream.Write(msgb, 0, msgb.Length);
error: Cannot send a content-body with this verb-type
and any additional informations.
I am trying to get an access OAuth2 token for Yelp Fusion Api using C# as mentioned in the documentation: https://www.yelp.com/developers/documentation/v3/get_started
However, I am getting the error :
client_id or client_secret not found. Make sure to provide client_id and client_secret in the body with the application application/x-www-form-urlencoded
The following is the code snippet:
<code>
string baseURL = "https://api.yelp.com/oauth2/token";
Dictionary<string, string> query = new Dictionary<string, string>();
query["grant_type"] = "client_credentials";
query["client_id"] = CONSUMER_KEY;
query["client_secret"] = CONSUMER_SECRET;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(baseURL);
request.Accept = "application/json";
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
StreamWriter requestWriter = new StreamWriter(request.GetRequestStream());
requestWriter.Write(query.ToString());
requestWriter.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
var stream = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
Console.WriteLine(stream.ReadToEnd());
</code>
As per the Yelp Fusion documentation here you need to make a POST call and parameters should be sent in application/x-www-form-urlencoded format. So the method used above is incorrect.
This should help:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(baseURL);
webRequest.Method = "POST";
webRequest.AllowAutoRedirect = true;
webRequest.Timeout = 20 * 1000;
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
webRequest.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36";
//write the data to post request
String postData = "client_id=" + CLIENT_ID + "&client_secret=" + CLIENT_SECRET + "&grant_type=client_credentials";
byte[] buffer = Encoding.Default.GetBytes(postData);
if (buffer != null)
{
webRequest.ContentLength = buffer.Length;
webRequest.GetRequestStream().Write(buffer, 0, buffer.Length);
}
HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string strResponse = reader.ReadToEnd();
Please note that the example above will return data in String format. To read the actual values, you will have to serialize the data.
Edit: Since March 1, 2018, the authentication process for yelp fusion API has changed. This is not applicable any more.
