Slack Integration - How to notify user with # when posted to channel

I have this code that notifies a slack channel after a build has completed. In certain cases, whenever the build fails, I want to add a notification to myself so I can quickly turn issues around. How can I update this to include a notification to someone using the # symbol?
Some examples I see online use the SlackMessage constructor to add a userName, but for some reason I can not overload this constructor.
public static void PostToSlack()
{
string url= "...";
string slackUrl = GlobalData.slackUrl;
string buildName = TestContext.Parameters["BuildName"];
string buildID = TestContext.Parameters["BuildID"];
string testName = TestContext.CurrentContext.Test.Name;
string outcome = TestContext.CurrentContext.Result.Outcome.ToString();
//If tests failed but the suite actually completed, set more understandable outcome message
if (outcome == "Failed(Child)")
{
outcome = "Completed with Issues";
}
//Build the text string to post to slack
string postText = "Build Completed";
SlackMessage message = new SlackMessage
{
text = postText
};
//Convert serializable object to JSON
string json = JsonConvert.SerializeObject(message, Newtonsoft.Json.Formatting.Indented);
var httpWebRequest = (HttpWebRequest)WebRequest.Create(slackUrl);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
//Send to Slack
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
//Error checking if Slack sends back a 404 or 400
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
}

Getting 404 error only when using .NET framework

I'm trying to create a version in JIRA for a specific project.
I'm able to do the process via Postman by building my requests manually, but it fails with a 404 when creating the version record via .NET.
I'm assuming .NET adds pesky parameters to the request that Postman doesn't do.
The weird thing is that the authentication call works, but the the version creation fails.
Here's the helper I wrote:
public class JIRA
{
private string AuthToken { get; set; }
private const string c_JIRAUrl = "https://org.atlassian.net";
private const string c_LoginUrl = c_JIRAUrl + "/rest/auth/1/session";
private const string c_CreateVersionUrl = c_JIRAUrl + "/rest/api/2/version";
public JIRA()
{
//this works...
var authResponse = ExecuteRequest(c_LoginUrl, "POST", new
{
username = "login",
password = "password"
});
AuthToken = authResponse["session"]["value"].ToString();
}
public void CreateVersion(string name, string projectKey, ProjectEnvironment environment)
{
//lets hardcode the same data I use in Postman for testing purposes...
var createVersionResponse = ExecuteRequest(c_CreateVersionUrl, "POST", new
{
description = "An excellent version",
name = "1.1.2",
archived = false,
released = false,
project = "TEST"
});
}
private JObject ExecuteRequest(string url, string method, object data)
{
HttpWebResponse response;
var jsonDataString = JsonConvert.SerializeObject(data);
byte[] dataBytes = Encoding.Default.GetBytes(jsonDataString);
var responseText = string.Empty;
var wr = (HttpWebRequest)WebRequest.Create(url);
wr.ContentType = "application/json";
if (!string.IsNullOrEmpty(AuthToken))
wr.Headers.Add(HttpRequestHeader.Authorization, $"Bearer {AuthToken}");
wr.Method = method;
wr.ContentLength = dataBytes.Length;
wr.Accept = "application/json";
using (var webStream = wr.GetRequestStream())
{
webStream.Write(dataBytes, 0, dataBytes.Length);
response = (HttpWebResponse)wr.GetResponse();
}
using (var sr = new StreamReader(response.GetResponseStream()))
{
responseText = sr.ReadToEnd();
}
return JObject.Parse(responseText);
}
}
The CreateVersion method always fails with a 404.
As I've said, doing the same (retrieving the token, creating the version) all works in Postman.
Any ideas what's going on ?
Thanks.

Apparently, when retrieving the token (/rest/auth/1/session) the response contains cookies that POSTMAN was sending back in the 2nd request (creating the version). I had to fire up Fiddler to find out it was doing so because its UI was not saying so.
My .NET client was not doing so. When making it do so, it works.
I'm a little miffed that a REST service expects cookies...

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);
}

Unable to Post on Pinterest using their API

I'm receiving a 400 Bad Request error message when posting a pin on Pinterest. It works using Postman, but doesn't work programmatically. Using C#, has anyone been able to successfully post a pin on Pinterest without using the pinsharp wrapper?
private void postPinterest(string messages, string id, string usertoken, string image, string boardname, string username)
{
string link = null;
boardname = boardname.Replace(" ", "-");
string board = username + "/" + boardname;
string url = "https://api.pinterest.com/v1/pins?access_token=" + usertoken;
StringBuilder sb = new StringBuilder();
if (!string.IsNullOrEmpty(board))
sb.Append("&board=" + HttpUtility.UrlEncode(board));
if (!string.IsNullOrEmpty(messages))
sb.Append("&note=" + HttpUtility.UrlEncode(messages));
if (!string.IsNullOrEmpty(link))
sb.Append("&image_url=" + HttpUtility.UrlEncode(link));
string postdata = sb.ToString().Substring(1);
PostData(url, postdata);
}
private object PostData(string url, string postdata)
{
object json=null;
try
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
// req.Accept = "application/json";
using (var stream = req.GetRequestStream())
{
byte[] bindata = Encoding.ASCII.GetBytes(postdata);
stream.Write(bindata, 0, bindata.Length);
}
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
string response = new StreamReader(resp.GetResponseStream()).ReadToEnd();
json = JsonConvert.DeserializeObject<dynamic>(response);
return json;
}
catch (WebException wex)
{
if (wex.Response != null)
{
using (var errorResponse = (HttpWebResponse)wex.Response)
{
using (var reader = new StreamReader(errorResponse.GetResponseStream()))
{
string error = reader.ReadToEnd();
return json;
}
}
}
}
return json;
}
EDIT:
It doesn't work using the JSON format or x-www-form-urlencoded format.
I changed the content type to application/x-www-form-urlencoded and now I'm receiving the error message below. I receive 400 Bad Request error using JSON format:
"{\n \"message\": \"405: Method Not Allowed\",\n \"type\": \"http\"\n}"

The problem is the the parameter that you are posting.
In the Api i could find board as a parameter but both note and image comes under field parameter which specifies the return type JSON.
As per documentation on this page you can post in this format
https://api.pinterest.com/v1/boards/anapinskywalker/wanderlust/pins/?
access_token=abcde&
limit=2&
fields=id,link,counts,note
So I tried the following and its getting response
https://api.pinterest.com/v1/boards/?access_token="YourTokenWithoutQuotes"&fields=id%2Ccreator
Would suggest you to first test the Api you are hitting putting a breakpoint inside the PostData function and check if the passed url is in the correct format and compare it with Pininterest API Explorer.
As you might have already received authorization code and access token so I am assuming your post function should be working fine.

public string postPinterest(string access_token,string boardname,string note,string image_url)
{
public string pinSharesEndPoint = "https://api.pinterest.com/v1/pins/?access_token={0}";
var requestUrl = String.Format(pinSharesEndPoint, accessToken);
var message = new
{
board = boardname,
note = note,
image_url = image_url
};
var requestJson = new JavaScriptSerializer().Serialize(message);
var client = new WebClient();
var requestHeaders = new NameValueCollection
{
{"Content-Type", "application/json" },
{"x-li-format", "json" }
};
client.Headers.Add(requestHeaders);
var responseJson = client.UploadString(requestUrl, "POST", requestJson);
var response = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(responseJson);
return response;
}

Error in json post request for mailchimp api

I am trying to create a wrapper for:
this mailchimp method using C#.Net
I understand that there are already .Net wrappers available. I am using Mailchimp.Net by Dan Esparza. Method in the wrapper class is giving exception for the api method mentioned above.It is throwing internal server exception (500) which I am not sure why, so I decided to create my own wrapper for the particular method. I have following code:
private void CreateGrouping(string apiKey, string listId,string groupName,string groupValue)
{
string url = "https://us9.api.mailchimp.com/2.0/lists/interest-grouping-add";
var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";
List<string> values = new List<string>();
values.Add(groupValue);
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = new JavaScriptSerializer().Serialize(new
{
apiKey = apiKey,
id = listId,
name = groupName,
type="radio",
groups = values
});
streamWriter.Write(json);
}
var response = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(response.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
}
But on execution of var response = (HttpWebResponse)httpWebRequest.GetResponse(); is throwing same exception - internal server error (500).
It might be that I am passing data in wrong way ? Can someone please help me in finding out what am I missing here ?

As I suspected I was passing the data in wrong way: apiKey has to be apikey (k was in caps)
string json = new JavaScriptSerializer().Serialize(new
{
apikey = apiKey,
id = listId,
name = groupName,
type="radio",
groups = values
});
Other than this, I added:
streamWriter.Flush();
streamWriter.Close();
It might help someone save sometime.
