Hey i am using this code for post on Facebook using c# but the problem is that it's not post as a page it's post as a user. I want to post as a Page in my Fan page. please give me a solution using the above code. and one more thing i want life-time Working access_token what should i do ?
thanks in advance

public static string GetPageAccessToken(string userAccessToken)
{
FacebookClient fbClient = new FacebookClient();
fbClient.AppId = "*****";
fbClient.AppSecret = "**************";
fbClient.AccessToken = userAccessToken;
Dictionary<string, object> fbParams = new Dictionary<string, object>();
JsonObject publishedResponse = fbClient.Get("/me/accounts", fbParams) as JsonObject;
JArray data = JArray.Parse(publishedResponse["data"].ToString());
foreach (var account in data)
{
if (account["name"].ToString().ToLower().Equals("opening shortly"))
{
return account["access_token"].ToString();
}
}
return String.Empty;
}
this code is working for me for refreshing page access tokens every time
just add
client.Post("/1038145769594318/feed", new
{
message = " test page post",
picture = "",
name = "Nikunj Patel",
link = "www.extrabucks.in",
description = "Test Description",
type = "photo",
access_token = GetPageAccessToken(access_token)
});

Jira Rest Api Login in C# [duplicate]

I've written below C# code to login to JIRA Rest API:
var url = new Uri("http://localhost:8090/rest/auth/latest/session?os_username=tempusername&os_password=temppwd");
var request = WebRequest.Create(url) as HttpWebRequest;
if (null == request)
{
return "";
}
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = 200;
request.KeepAlive = false;
using (var response = request.GetResponse() as HttpWebResponse)
{
}
When I execute this, application just goes on running without returning any response. Please suggest if this is the right way of calling JIRA Login using REST API

For basic authentication you need to send in the username and password in a base64-encoding. Guidelines can be found in the API examples on atlassians developer page:
https://developer.atlassian.com/display/JIRADEV/JIRA+REST+API+Example+-+Basic+Authentication
, if you are doing it in C# you need to send the encoded data in the header in the following format:
"Authorization: Basic [ENCODED CREDENTIALS]"
Here is a simple example:
public enum JiraResource
{
project
}
protected string RunQuery(
JiraResource resource,
string argument = null,
string data = null,
string method = "GET")
{
string url = string.Format("{0}{1}/", m_BaseUrl, resource.ToString());
if (argument != null)
{
url = string.Format("{0}{1}/", url, argument);
}
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.ContentType = "application/json";
request.Method = method;
if (data != null)
{
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(data);
}
}
string base64Credentials = GetEncodedCredentials();
request.Headers.Add("Authorization", "Basic " + base64Credentials);
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
string result = string.Empty;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
result = reader.ReadToEnd();
}
return result;
}
private string GetEncodedCredentials()
{
string mergedCredentials = string.Format("{0}:{1}", m_Username, m_Password);
byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
return Convert.ToBase64String(byteCredentials);
}
(JiraResource is just an enum I use to decide which part of the API to use)
I hope this will help!

Here is a simpler solution which works as required:
var mergedCredentials = string.Format("{0}:{1}", username, password);
var byteCredentials = Encoding.UTF8.GetBytes(mergedCredentials);
var encodedCredentials = Convert.ToBase64String(byteCredentials);
using (WebClient webClient = new WebClient())
{
webClient.Headers.Set("Authorization", "Basic " + encodedCredentials);
return webClient.DownloadString(url);
}

If you don't want to encode your credentials in every request here is how to do it using cookies.
When requesting the cookie you don't need to add any authorization on the headers. This method will accept a JSON string with the user name and password and the URL. It will return the cookie values.
public async Task<JiraCookie> GetCookieAsync(string myJsonUserNamePassword, string JiraCookieEndpointUrl)
{
using (var client = new HttpClient())
{
var response = await client.PostAsync(
JiraCookieEndpointUrl,
new StringContent(myJsonUserNamePassword, Encoding.UTF8, "application/json"));
var json = response.Content.ReadAsStringAsync().Result;
var jiraCookie= JsonConvert.DeserializeObject<JiraCookie>(json);
return jArr;
}
}
public class JiraCookie
{
public Session session { get; set; }
}
public class Session
{
public string name { get; set; }
public string value { get; set; }
}
When I call it using url: http://[baseJiraUrl]/rest/auth/1/session it returns the following JSON response:
{
"session" : -{
"name" : JSESSIONID,
"value" : cookieValue
}
Keep in mind the URL above is valid in the version of JIRA I'm using and may vary depending on which version you're using. Read the JIRA API documentation for the correct URL for the version you are using. I'm using the following:
https://docs.atlassian.com/software/jira/docs/api/REST/7.6.1/#auth/1/session
Remember you'll have to store your cookie and use it on every subsequent request.
Check out this answer on how add cookies to your HttpClient request: How do I set a cookie on HttpClient's HttpRequestMessage.
Once you're done with the cookie (logging out) simply send a delete http request with the same URL as the post.

I tweaked the RunQuery code so that it will run today (Apr 2018). The encrypt/decrypt referenced below is from the following link (I converted it to an extension method and threw values into environment).
https://stackoverflow.com/questions/10168240/encrypting-decrypting-a-string-in-c-sharp
I successfully execute the code from LinqPad - thus the Dump() command after RunQuery
private string _baseUrl = "https://xxxxxx.atlassian.net";
private string _username = "YourLogin";
void Main()
{
RunQuery(JiraResource.project).JsonToXml().Dump();
}
public enum JiraResource { project }
private const string restApiVersion = "/rest/api/2/";
protected string RunQuery( JiraResource resource, string argument = null, string data = null, string method = "GET")
{
string url = $"{_baseUrl}{restApiVersion}{resource}";
if (argument != null) url = $"{url}{argument}/";
var request = WebRequest.Create(url) as HttpWebRequest;
request.ContentType = "application/json";
request.Method = method;
if (data != null)
{
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(data);
}
}
string base64Credentials = GetEncodedCredentials();
request.Headers.Add("Authorization", "Basic " + base64Credentials);
var response = request.GetResponse() as HttpWebResponse;
string result = string.Empty;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
result = reader.ReadToEnd();
}
return result;
}
private string GetEncodedCredentials()
{
var encryptedPassword = Environment.GetEnvironmentVariable("PassEncrypted");
var encryptionSalt = Environment.GetEnvironmentVariable("PassSalt");
var password = encryptedPassword.Decrypt(encryptionSalt);
var mergedCredentials = $"{_username}:{password}";
var byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
return Convert.ToBase64String(byteCredentials);
}
public static class MyExtensions
{
public static XElement JsonToXml(this string jsonData, bool isAddingHeader = true)
{
var data = isAddingHeader
? "{\"record\":" + jsonData + "}"
: jsonData;
data = data // Complains if xml element name starts numeric
.Replace("16x16", "n16x16")
.Replace("24x24", "n24x24")
.Replace("32x32", "n32x32")
.Replace("48x48", "n48x48");
var result = JsonConvert.DeserializeXmlNode(data, "data");
var xmlResult = XElement.Parse(result.OuterXml);
return xmlResult;
}
}

For posting multipart content in Rest I use Tiny.RestClient.
var client = new TinyRestClient(new HttpClient(), "http://localhost:8090");
var strResult = await client.PostRequest("rest/auth/latest/session).
WithBasicAuthentication("username", "password")
ExecuteAsStringAsync();

static void Main(string[] args)
{
using (WebClient wc = new WebClient())
{
wc.Headers.Add("Authorization", "Basic " + GetEncodedCredentials());
string tasks = wc.DownloadString("yourjiraurl/search?jql=task=bug");
var taskdetails = JsonConvert.DeserializeObject<TaskDetails>(tasks);
}
}
static string GetEncodedCredentials()
{
string mergedCredentials = string.Format("{0}:{1}", "UserName", "Password");
byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
return Convert.ToBase64String(byteCredentials);
}

Post to Facebook Page as page

After quite searching i was able to post on Facebook Page as myself. but my target was to post on the Page i manage as the page. I did some more research and i was able to get the access token of the page i manage. when i tried to POST on it, sdk gave me the error that
The user hasn't authorized the application to perform this action
here is my code for your reference :
string app_id = "xxxxx";
string app_secret = "yyyyyyy";
string scope = "publish_actions,manage_pages";
if (Request["code"] == null)
{
string url = string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_id, Request.Url.AbsoluteUri, scope);
Response.Redirect(url, 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, Request.Url.AbsoluteUri, scope, Request["code"].ToString(), app_secret);
HttpWebRequest request = System.Net.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('&'))
{
tokens.Add(token.Substring(0, token.IndexOf("=")),
token.Substring(token.IndexOf("=") + 1, token.Length - token.IndexOf("=") - 1));
}
}
string access_token = tokens["access_token"];
var client = new FacebookClient(access_token);
dynamic parameters = new ExpandoObject();
parameters.message = "Check out this funny article";
parameters.link = "http://www.natiska.com/article.html";
parameters.picture = "http://www.natiska.com/dav.png";
parameters.name = "Article Title";
parameters.caption = "Caption for the link";
//zzzzzzz is my fan page
string pageAccessToken = "";
JsonObject jsonResponse = client.Get("me/accounts") as JsonObject;
foreach (var account in (JsonArray)jsonResponse["data"])
{
string accountName = (string)(((JsonObject)account)["name"]);
if (accountName == MY_PAGE_NAME)
{
pageAccessToken = (string)(((JsonObject)account)["access_token"]);
break;
}
}
client = new FacebookClient(pageAccessToken);
client.Post("/zzzzzzz/feed", parameters);

You need the publish_pages permission to post as pages.
https://developers.facebook.com/docs/graph-api/reference/v2.3/page/feed#publish

Your Facebook App Dosn't have manage_page & publish_page permission, instead of this you can create test application and from that u can create test users for your testing .
From there u can manage all the pages posts and data.

using HttpWebRequest two or more times via c#

I have one problem. I have two methods which use HttpWebRequest. One of them post a message to my facebook wall. Another take count number of likes.
Thare is code:
if (Request["code"] == null)
{
Response.Redirect(string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_id, Request.Url.AbsoluteUri, scope));
}
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, Request.Url.AbsoluteUri, scope, 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));
}
}
//get wall data
string access_token = tokens["access_token"];
var client = new FacebookClient(access_token);
//post message to my wall or image
dynamic messagePost = new ExpandoObject();
messagePost.message = "I need to get an id of this post";
try
{
var postId = client.Post("me/feed", messagePost);
id_mypost = postId["id"];
}
catch (FacebookOAuthException ex)
{
//handle oauth exception
}
catch (FacebookApiException ex)
{
//handle facebook exception
}
}
This method post message to my wall. Thare is the second method:
if (Response.BufferOutput == true)
{
if (Request["code"] == null)
{
Response.Redirect(string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_id, Request.Url.AbsoluteUri, scope));
}
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, Request.Url.AbsoluteUri, scope, 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));
}
}
string access_token = tokens["access_token"];
var client = new FacebookClient(access_token);
try
{
string str = client.Get("/me/feed").ToString();
JObject obj = JObject.Parse(str);
JToken jUser = obj["data"];
int numb = jUser.Count();
int id_post = 0;
for (int i = 0; i < numb; i++)
{
if (obj["data"][i]["id"].ToString() == id_mypost)
{
id_post = i;
}
}
string strr = obj["data"][id_post]["likes"].ToString();
string pattern = #"id";
int count_like = 0;
Regex newReg = new Regex(pattern);
MatchCollection matches = newReg.Matches(strr);
foreach (Match mat in matches)
{
count_like++;
}
}
catch (Exception)
{
}
}
So thare is the problem. I use two times HttpWebRequest. So , when I bild my app i got next error: Cannot redirect after HTTP headers have been sent.
Can somebody help me ?

Cannot redirect after HTTP headers have been sent.
This is the error of asynchronous operation. For example if you are using any thread operation and in that thread you try Response.redirect it will give this error.
The response is already sent to client before the statement executes.
Can you please tell me where exactly the error is occurring ?

How to use Magento REST API from C#

Where can I find samples that show how to connect to the Magento REST API using C#?
I found was a php one which I could not figure out except a little.
Using a Dropbox OAuth sample I found on the net I tried to make it work for Magento:
private void button1_Click(object sender, RoutedEventArgs e)
{
var consumerKey = “xxxxxxxxxxxxx”;
var consumerSecret = “xxxxxxxxxxxxxxxx”;
var uri = new Uri("http://www.MagentoWebsite.com/oauth/token");
// Generate a signature
OAuthBase oAuth = new OAuthBase();
string nonce = oAuth.GenerateNonce();
string timeStamp = oAuth.GenerateTimeStamp();
string parameters;
string normalizedUrl;
string signature = oAuth.GenerateSignature(uri, consumerKey, consumerSecret,
String.Empty, String.Empty, “GET”, timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1,
out normalizedUrl, out parameters);
signature = HttpUtility.UrlEncode(signature);
StringBuilder requestUri = new StringBuilder(uri.ToString());
requestUri.AppendFormat("?oauth_consumer_key={0}&", consumerKey);
requestUri.AppendFormat("oauth_nonce={0}&", nonce);
requestUri.AppendFormat("oauth_timestamp={0}&", timeStamp);
requestUri.AppendFormat("oauth_signature_method={0}&", “HMAC-SHA1");
requestUri.AppendFormat("oauth_version={0}&", “1.0");
requestUri.AppendFormat("oauth_signature={0}", signature);
var request = (HttpWebRequest)WebRequest.Create(new Uri(requestUri.ToString()));
request.Method = WebRequestMethods.Http.Get;
var response = request.GetResponse();
var queryString = new StreamReader(response.GetResponseStream()).ReadToEnd();
var parts = queryString.Split(’&’);
var token = parts[1].Substring(parts[1].IndexOf(’=’) + 1);
var tokenSecret = parts[0].Substring(parts[0].IndexOf(’=’) + 1);
queryString = String.Format("oauth_token={0}", token);
var authorizeUrl = “http://www.MagentoWebsite.com/admin/oauth_authorize?”+queryString;
Process.Start(authorizeUrl);
}
Unfortunately this returns a BAD REQUEST response.

I recently started a project for a C# REST API client for Magento that might help you out:
https://github.com/nickvane/Magento-RestApi
It's not yet feature complete, but the oauth authentication is implemented.
The code uses restsharp which has support for oauth authentication.

I had the same question but couldn't find the answer hence I spent a day to make it work. I share my code here and I hope it will help other people in the feature.
use the following code in an aspx page to get oAuth access

also don't forget to add the https://oauth.googlecode.com/svn/code/csharp/OAuthBase.cs to the project
it's ready to use. to read from api :
var request = CreateAuthorizedRequest(MagentoServer + "/api/rest/products", "get", new ApiFilter() {Page = 1 });
var responseText = FetchRequest(request);
Magento REST Api documantion can be found here

you can quickly create a client REST API using Spring.NET Social :
http://www.springframework.net/social/
Magento uses OAuth 1.0a authentication like Twitter. You can take a look to the Twitter implementation here:
http://www.springframework.net/social-twitter/
And the related documentation with step by step instructions:
http://www.springframework.net/social/refdoc/implementing.html

I'm not sure if this helps or not, but once I was able to get the oauth_token and oauth_token_secret from Magento (I used a PHP Magento sample to get it) I was able to query the REST API by putting everything in your requestUri into the header.
Your example helped me get most of the code correct, and just modified it a little (here's a little snippet):
StringBuilder sb = new StringBuilder("OAuth ");
sb.AppendFormat("oauth_version={0},", "1.0");
sb.AppendFormat("oauth_signature_method={0},", "HMAC-SHA1");
sb.AppendFormat("oauth_nonce={0},", nonce);
sb.AppendFormat("oauth_timestamp={0},", timeStamp);
sb.AppendFormat("oauth_consumer_key={0},", consumerKey);
sb.AppendFormat("oauth_token={0},", oauth_token);
sb.AppendFormat("oauth_signature={0}", sig);
Debug.WriteLine(sb.ToString());
var request = (HttpWebRequest)WebRequest.Create((resourceUrl));
request.Headers[HttpRequestHeader.Authorization] = sb.ToString();
request.ContentType = "text/xml";
request.Accept = "text/xml";
request.KeepAlive = true;
//request.Method = WebRequestMethods.Http.Get;
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Debug.WriteLine(response.StatusCode);
Debug.WriteLine(response.Server);
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
StreamReader responseReader = new StreamReader(responseStream);
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(response.GetResponseStream());
Dts.Variables["User::XML_Response"].Value = xmlDoc.OuterXml.ToString();
}
Does that help?
