Unauthorized Access Exception While Using Yahoo Weather API

I have done code to access yahoo weather API with oath by following all steps provided by yahoo in documentation as
1) Create Yahoo account
2) Create App
3) White list App
4) C# code to access yahoo weather API with oath
I am getting Unauthorized access exception while requesting API.
Here is the code :
public class WeatherYdn
{
public static void Main(string[] args)
{
const string appId = "YOUR-WHITELISTED-APPID";
const string consumerKey = "YOUR-CONSUMER-KEY";
const string consumerSecret = "YOUR-SECRET-KEY";
const string url = "https://weather-ydn-yql.media.yahoo.com/forecastrss";
string timestamp = StringHelper.GenerateTimeStamp();
String oauthNonce = StringHelper.GenerateNonce();
IList<string> parameters = new List<string>();
parameters.Add("oauth_consumer_key=" + consumerKey);
parameters.Add("oauth_nonce=" + oauthNonce);
parameters.Add("oauth_signature_method=HMAC-SHA1");
parameters.Add("oauth_timestamp=" + timestamp);
parameters.Add("oauth_version=1.0");
// Make sure value is encoded
parameters.Add("location=" + HttpUtility.UrlEncode("pune,in", Encoding.UTF8));
parameters.Add("format=json");
((List<string>) parameters).Sort();
StringBuilder parametersList = new StringBuilder();
for (int i = 0; i < parameters.Count; i++)
{
parametersList.Append(((i > 0) ? "&" : "") + parameters.ElementAt(i));
}
var signatureString = "GET&" +
HttpUtility.UrlEncode(url,Encoding.UTF8) + "&" +
HttpUtility.UrlEncode(parametersList.ToString(), Encoding.UTF8);
string signature = null;
try
{
string secretAccessKey = consumerSecret;
byte[] secretKey = Encoding.UTF8.GetBytes(secretAccessKey);
HMACSHA1 hmac = new HMACSHA1(secretKey);
hmac.Initialize();
byte[] bytes = Encoding.UTF8.GetBytes(signatureString);
byte[] rawHmac = hmac.ComputeHash(bytes);
signature = Convert.ToBase64String(rawHmac);
}
catch (Exception e)
{
Console.WriteLine("Unable to append signature");
}
string authorizationLine = "OAuth " +

"oauth_nonce=\"" + oauthNonce + "\", " +
"oauth_timestamp=\"" + timestamp + "\", " +
"oauth_signature_method=\"HMAC-SHA1\", " +
"oauth_signature=\"" + signature + "\", " +
"oauth_version=\"1.0\"";
HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url + "?location=pune,in&format=json");
request.Headers.Add("Authorization", authorizationLine);
request.Headers.Add("Yahoo-App-Id", appId);
request.ContentType = "application/json; charset=UTF-8";
request.Accept = "application/json";
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
Stream receiveStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
Console.WriteLine(readStream.ReadLine());
}
}

In which line you get the error? The GetResponse() returns it?
I think that the credentials you are using (appId,consumerKey,consumerSecret) are invalid!

public string appId = "Your app-id";
public string consumerKey = "Your-consumer key";
public string consumerSecret = "Your Consumer Secret key";
// GET: api/Random
[HttpGet("{CityName}")]
public async Task<IActionResult> GetAsync([FromUri] string CityName)
{
string urlss = "https://weather-ydn-yql.media.yahoo.com/forecastrss?location=";
string url = urlss + CityName+ "&format=json&u=c";
JObject jresult;
using (var client = new HttpClient())
{
try
{
var webClient = new WebClient();
webClient.Headers.Add(AssembleOAuthHeader());
var d = webClient.DownloadString(url);
jresult = JObject.Parse(d);
var json_jsonstring = Newtonsoft.Json.JsonConvert.SerializeObject(jresult);
return Ok(json_jsonstring);
}
catch (HttpRequestException httpRequestException)
{
return BadRequest($"Error getting weather from Yahoo Weather: {httpRequestException.Message}");
}
}
}
public string AssembleOAuthHeader()
{
return "Authorization: OAuth " +
"realm=\"yahooapis.com\"," +
"oauth_consumer_key=\"" + consumerKey + "\"," +

"oauth_version=\"1.0\"," +
"oauth_signature=\"" + consumerSecret + "%26\"," +

}

For yahoo weather new authentication you can use this python library
yahoo-weather

I think your code is fine. The problem lies with a poorly implemented URL Decode on Yahoo's end. Java URL Encode encodes with uppercase while .net HTTPUtility.URLEncode encodes in lower case. I created an extension method for a string that will rectify the problem and URL Encode in a way that the Yahoo API can handle. After doing that all worked well (I had the exact same problem you did).
<Extension>
Public Function UppercaseURLEncode(ByVal sourceString As String) As String
Dim temp As Char() = HttpUtility.UrlEncode(sourceString).ToCharArray()
For i As Integer = 0 To temp.Length - 2
If temp(i).ToString().Equals("%", StringComparison.OrdinalIgnoreCase) Then
temp(i + 1) = Char.ToUpper(temp(i + 1))
temp(i + 2) = Char.ToUpper(temp(i + 2))
End If
Next
Return New String(temp)
End Function

c# URL POST Web API

I'm trying to do a function which work with WECHAT API,
Here is my code:
I use the code below to get a connection Token
internal static string Token(string CorpID, string Secret)
{
CorpID = CorpID ?? "wwe1f80304633";
Secret = Secret ?? "Ev7_oVN7RqD9k4yUy5pzkfcZ_QhX9l0VjZnAQ";
string token;
using (var wc = new WebClient())
{
token = wc.DownloadString($"https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={CorpID}&corpsecret={Secret}");
}
if (token.Contains("access_token"))
{
return token.Split(',')[2].Split(':')[1].Replace("\"", "");
}
return "";
}
It's successful to get a valid token from WECHAT Server,
And the code below is I want to POST a request to WECHAT API and ask WECHAT to Send Message to selected Department Person.
internal static string SendMsg(string sendtext)
{
string ACTOKEN = "" + PDC.MSGTOKEN + "";
string CONTENT = "" + PDC.CONTENT + "";
string PostUrl;
using (var wc2 = new WebClient())
{
PostUrl = wc2.UploadString($"https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={0}{1}", ACTOKEN, CONTENT);
}
return "";
}
public static void SendMsg2()
{
PDC.CONTENT = "Test Message";
string MsgContent = "{\"toparty\": \"" + PDC.DEPTID + "\",\"msgtype\": \"text\",\"agentid\": \"" + PDC.AGENTID + "\",\"text\": {\"content\": \"" + PDC.CONTENT + "\"},\"safe\":0}";
SendMsg(MsgContent);
MessageBox.Show("" + MsgContent + "");
}
And I Added a button on my WinForm and trying to make it work
private void BtnSendMsg_Click(object sender, EventArgs e)
{
string token = MSG.Token(null, null);
if (!string.IsNullOrEmpty(token))
{
PDC.MSGTOKEN = token;
MessageBox.Show("" + PDC.MSGTOKEN + "");
}
else
{
MessageBox.Show(" Invalid Token ");
}
MSG.SendMsg2();
}
However seems it doesn't work, and if I'm not wrong the problem on this part
internal static string SendMsg(string sendtext)
{
string ACTOKEN = "" + PDC.MSGTOKEN + "";
string CONTENT = "" + PDC.CONTENT + "";
string PostUrl;
using (var wc2 = new WebClient())
{
PostUrl = wc2.UploadString($"https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={0}{1}", ACTOKEN, CONTENT);
}
return "";
}
May anyone can give me some ideas how I can solve this problem ? Many Many Many Thanks ~

I has been done my Code without Problem, this is the code below for everyone who need.
The code to get Token from Https API

I did everything according to this page . Now I am just lost, any Idea why does it not work?

You are not calculating the oauth_timestamp correctly. This should be calculated as Unix time which is the number of seconds since 00:00:00 UTC on 1 Jan 1970.
int unixTimestamp = (int)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds;
or using .NET 4.6
long unixTimestamp = DateTimeOffset.UtcNow.ToUnixTimeSeconds();
Also the signing key used for creating the signature should be a concatenation of the percent encoded consumer secret and the percent encoded token secret joined by an ampersand (&). In the case of obtaining a request token the token secret is not yet known so you should just use the consumer secret followed by an ampersand (&).
var signingKey = oauth_consumer_key_enc + "&";
Finally you should return the Base64 encoded string after you have computed your hash so your function becomes:
private string ShaHash(string value, string signingKey)
{
using (var hmac = new HMACSHA1(Encoding.ASCII.GetBytes(signingKey)))
{
return Convert.ToBase64String(hmac.ComputeHash(Encoding.ASCII.GetBytes(value)));
}
}

Get Yahoo Contact List in C# application

As guidance on https://developer.yahoo.com/oauth/guide/oauth-requesttoken.html, Below are what I did with OAuth to get Yahoo contact list:
Make a GET request to https://api.login.yahoo.com/oauth/v2/get_request_token
to get oauth_token and oauth_token_secret, I successfully get them.
Example url:
OAuthBase oath = new OAuthBase();
string url = "https://api.login.yahoo.com/oauth/v2/get_request_token?" +
"oauth_nonce=" + oath.GenerateNonce() +
"&oauth_timestamp=" + oath.GenerateTimeStamp() +
"&oauth_consumer_key=" + consumerKey+
"&oauth_signature_method=plaintext" +
"&oauth_signature=" + consumerSecret + "%26" + //%26 if plaintext
"&oauth_version=1.0" +
"&oauth_callback=" + "oob";
Using oauth_token of step 1. to make a GET request to https://api.login.yahoo.com/oauth/v2/request_auth?oauth_token={token}, It returned me oauth_verifier
Using paramters of step 1 and 2 to make GET request to https://api.login.yahoo.com/oauth/v2/get_token , it returned me new oauth_token , oauth_token_secret, oauth_session_handle, xoauth_yahoo_guid.
Example url:
string sig = consumerSecret + "%26" + OauthTokenSecret;
string url = "https://api.login.yahoo.com/oauth/v2/get_token?" +
"oauth_consumer_key=" + consumerKey+
"&oauth_signature_method=plaintext" +
"&oauth_signature=" + sig +
"&oauth_timestamp=" + oath.GenerateTimeStamp() +
"&oauth_version=1.0" +
"&oauth_token=" + OAuthToken +
"&oauth_nonce=" + oath.GenerateNonce() +
"&oauth_verifier=" + oauth_verifier;
The final step is to get the contact list:
I make a GET request to https://social.yahooapis.com/v1/user/{xoauth_yahoo_guid}/contacts?format=json
Example
Uri uri = new Uri(url);
string nonce = oath.GenerateNonce();
string timeStamp = oath.GenerateTimeStamp();
string normalizedUrl;
string normalizedRequestParameters;
string sig = oath.GenerateSignature(uri, clientId, clientSecret, yahooToken.OAuthToken,
yahooToken.OauthTokenSecret, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1,
out normalizedUrl, out normalizedRequestParameters);
Function GenerateSignature:
public string GenerateSignature(Uri url, string consumerKey, string consumerSecret, string token, string tokenSecret, string httpMethod, string timeStamp, string nonce, SignatureTypes signatureType, out string normalizedUrl, out string normalizedRequestParameters)
{
normalizedUrl = null;
normalizedRequestParameters = null;
switch (signatureType)
{
case SignatureTypes.PLAINTEXT:
return HttpUtility.UrlEncode(string.Format("{0}&{1}", consumerSecret, tokenSecret));
case SignatureTypes.HMACSHA1:
string signatureBase = GenerateSignatureBase(url, consumerKey, token, tokenSecret, httpMethod, timeStamp, nonce, HMACSHA1SignatureType, out normalizedUrl, out normalizedRequestParameters);
HMACSHA1 hmacsha1 = new HMACSHA1();
hmacsha1.Key = Encoding.ASCII.GetBytes(string.Format("{0}&{1}", UrlEncode(consumerSecret), string.IsNullOrEmpty(tokenSecret) ? "" : UrlEncode(tokenSecret)));
return GenerateSignatureUsingHash(signatureBase, hmacsha1);
case SignatureTypes.RSASHA1:
throw new NotImplementedException();
default:
throw new ArgumentException("Unknown signature type", "signatureType");
}
}
Make request:
using (var client = new WebClient())
{
string authenHeader = "OAuth " +
"realm=\"yahooapis.com\"" +
",oauth_consumer_key=\"" + consumerKey+ "\"" +
",oauth_nonce=\"" + nonce + "\"" +
",oauth_signature_method=\"HMAC-SHA1\"" +
",oauth_timestamp=\"" + timeStamp + "\"" +
",oauth_token=\"" + OAuthToken + "\"" +
",oauth_version=\"1.0\"" +
",oauth_signature=\"" + HttpUtility.UrlEncode(sig) + "\"";
client.Headers.Set("Authorization", authenHeader);
string responseString = client.DownloadString(url);
}
But Yahoo sends me (401) Unauthorized response, Could you tell me where I'm wrong ?

I realized that I am stuck at the exact same place
System.Net.WebException: The remote server returned an error: (401) Unauthorized. at ..GetEmailContacts() in ...
private ArrayList GetEmailContacts() {
OAuthBase oauth = new OAuthBase();
Uri uri = new Uri("https://social.yahooapis.com/v1/user/" + OauthYahooGuid + "/contacts?format=XML");
string nonce = oauth.GenerateNonce();
string timeStamp = oauth.GenerateTimeStamp();
string normalizedUrl;
string normalizedRequestParameters;
string sig = oauth.GenerateSignature(uri, this.sConsumerKey, this.sConsumerSecret, OauthToken, OauthTokenSecret, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1, out normalizedUrl, out normalizedRequestParameters);
StringBuilder sbGetContacts = new StringBuilder(uri.ToString());
try {
string returnStr = string.Empty;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sbGetContacts.ToString());
req.Accept = "application/xml";
req.Method = "GET";
ArrayList emails = new ArrayList();
string authHeader = "Authorization: OAuth " +

",oauth_version=\"1.0\"" +
",oauth_signature=\"" + HttpUtility.UrlEncode(sig) + "\"";
req.Headers.Add(authHeader);
using (HttpWebResponse res = (HttpWebResponse)req.GetResponse()) {
:/ sighz
SO I found the issue. Ive changed the content format from XML to JSON
changed the following:
private ArrayList GetEmailContacts() {
OAuthBase oauth = new OAuthBase();
Uri uri = new Uri("https://social.yahooapis.com/v1/user/" + OauthYahooGuid + "/contacts?format=json");
string nonce = oauth.GenerateNonce();
string timeStamp = oauth.GenerateTimeStamp();
string normalizedUrl;
string normalizedRequestParameters;
string sig = oauth.GenerateSignature(uri, this.sConsumerKey, this.sConsumerSecret, OauthToken, OauthTokenSecret, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1, out normalizedUrl, out normalizedRequestParameters);
StringBuilder sbGetContacts = new StringBuilder(uri.ToString());
try {
string returnStr = string.Empty;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sbGetContacts.ToString());
req.Accept = "application/json";
req.ContentType = "application/json";
req.Method = "GET";
ArrayList emails = new ArrayList();
string authHeader = "Authorization: OAuth " +
"realm=\"yahooapis.com\"" +
",oauth_consumer_key=\"" + this.sConsumerKey + "\"" +
",oauth_nonce=\"" + nonce + "\"" +
",oauth_signature_method=\"HMAC-SHA1\"" +
",oauth_timestamp=\"" + timeStamp + "\"" +
",oauth_token=\"" + OauthToken + "\"" +
",oauth_version=\"1.0\"" +
",oauth_signature=\"" + HttpUtility.UrlEncode(sig) + "\"";
req.Headers.Add(authHeader);
using (HttpWebResponse res = (HttpWebResponse)req.GetResponse()) {
When I made that change it suddenly returned the emails and no more 406 error code.
I hope that this helps someone.. no idea as to why xml stopped working.

Use Request and Response variables in the static web method

Here is my code,
[WebMethod]
public static bool FirstAccess()
{
string app_id = "139295982898884";
string app_secret = "b5d2a88b56898610d54da2af498e3220";
//string post_login_url = "http://dev.fitbook.com.asp1-23.ord1-1.websitetestlink.com/v4/FitbookContest.aspx";
string post_login_url = "http://localhost:4327/FitbookContest.aspx";
string scope = "publish_stream,manage_pages";
string code = HttpContext.Current.Request["code"] ?? "";
try
{
if (code == "")
{
string dialog_url = "http://www.facebook.com/dialog/oauth?" + "client_id=" + app_id + "&redirect_uri=" + HttpContext.Current.Server.UrlEncode(post_login_url) + "&scope=publish_stream";
// HttpContext.Current.Response.Write(dialog_url);
//HttpContext.Current.Response.Redirect(dialog_url, true);
return false;
}
else
{
Dictionary<string, string> tokens = new Dictionary<string, string>();
string url = string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri={1}&scope={2}&code={3}&client_secret={4}", app_id, HttpContext.Current.Request.Url.AbsoluteUri, scope, HttpContext.Current.Request["code"].ToString(), app_secret);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string vals = reader.ReadToEnd();
foreach (string token in vals.Split('&'))
{
//meh.aspx?token1=steve&token2=jake&...
tokens.Add(token.Substring(0, token.IndexOf("=")), token.Substring(token.IndexOf("=") + 1, token.Length - token.IndexOf("=") - 1));
}
}
access_token = tokens["access_token"];
TestFB.GetProfilePic(code);
return true;
}
}
catch (Exception ex)
{
return false;
}
}
Here the lines like
HttpContext.Current.Request["code"] ?? "";
and
HttpContext.Current.Response.Redirect(dialog_url, true);
are not working. So is there any alternative solution for it? Is there any way to use it?

Have you tried this,
string dialog_url = "~http://www.facebook.com/dialog/oauth?" + "client_id=" + app_id + "&redirect_uri=" + HttpContext.Current.Server.UrlEncode(post_login_url) + "&scope=publish_stream";
and, redirect as false indicate Whether execution of current page should terminate
HttpContext.Current.Response.Redirect(dialog_url,false);
Simply try this:
string code = HttpContext.Current.Request["code"];
if (code==null)
{
// code
}
and I think the problem is in the line. You didn't specify accesstoken
