Google Contacts API OAuth2.0 not working - oauth-2.0

Here's a code snippet I found from the gdata sample codes. I tried incorporating this, but to no effect.
public ContactsExample(ContactsExampleParameters parameters)
throws MalformedURLException, AuthenticationException {
projection = parameters.getProjection();
String url = parameters.getBaseUrl() + (parameters.isGroupFeed() ? "groups/" : "contacts/") + parameters.getUserName() + "/" + projection;
feedUrl = new URL(url);
service = new ContactsService("MYAPP");
String userName = parameters.getUserName();
String password = parameters.getPassword();
if (userName == null || password == null) {
return;
}
service.setUserCredentials(userName, password);
}
I have these doubts:
1. Is the name specified as 'MYAPP' any random name, or does it have any significance?
2. Which is the userName and password supposed to be used here?

Calling an ASP.Net web api from a ASP.Net MVC web app. MVC web client is not building the URL properly so getting not found

When I run my web api method using Postman passing in my URL, it works fine - it returns the value of '5' which I expect since the call returns just a single integer. Also at the very bottom I include another method of my web api that I run using Postman and it too works just fine.
http://localhost:56224/api/profileandblog/validatelogin/DemoUser1/DemoUser1Password/169.254.102.60/
However, in the client - an Asp.Net MVC method, when building the URL, it is DROPPING the "/api/profileandblog" part. Note: I'm using "attribute routing" in the web api.
Here is the Asp.Net MVC method to call the web api:
I stop it on this line so I can see the error details: if (result1.IsSuccessStatusCode)
It's INCORRECTLY building the URL as: http://localhost:56224/validatelogin/DemoUser1/DemoUser1Password/169.254.102.60/
It's dropping the: "/api/profileandblog" part that should follow 56224.
So it give's me the Not found.
Why does it drop it? It has the localhost:56224 correct.
[HttpPost]

public ActionResult SignIn(SignInViewModel signInViewModel)

string myIpAddress = Dns.GetHostEntry(hostName).AddressList[2].ToString();
try
{
if (!this.IsCaptchaValid("Captcha is not valid"))
{
ViewBag.errormessage = "Error: captcha entered is not valid.";
}
else
{
if (!string.IsNullOrEmpty(signInViewModel.Username) && !string.IsNullOrEmpty(signInViewModel.Password))
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:56224/api/profileandblog");
string restOfUrl = "/validatelogin/" + signInViewModel.Username + "/" + signInViewModel.Password + "/" + myIpAddress + "/";
// Call the web api to validate the sign in.
// Sends back a -1(failure), -2(validation issue) or the UserId(success) via an OUTPUT parameter.
var responseTask1 = client.GetAsync(restOfUrl);
responseTask1.Wait();
var result1 = responseTask1.Result;

}
}
Per the suggestion about not having headers, I used another tutorial (https://www.c-sharpcorner.com/article/consuming-asp-net-web-api-rest-service-in-asp-net-mvc-using-http-client/) and it has the code for defining the headers. But it is coded slightly different - using async Task<> on the method definition. I was not using async in my prior version.
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> SignIn(SignInViewModel signInViewModel)
{
int returnedApiValue = 0;
User returnedApiUser = new User();
DateTime currentDateTime = DateTime.Now;
string hostName = Dns.GetHostName();
string myIpAddress = Dns.GetHostEntry(hostName).AddressList[2].ToString();
try
{
if (!this.IsCaptchaValid("Captcha is not valid"))
{
ViewBag.errormessage = "Error: captcha entered is not valid.";
}
else
{
if (!string.IsNullOrEmpty(signInViewModel.Username) && !string.IsNullOrEmpty(signInViewModel.Password))
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:56224/api/profileandblog");
string restOfUrl = "/validatelogin/" + signInViewModel.Username + "/" + signInViewModel.Password + "/" + myIpAddress + "/";
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// Call the web api to validate the sign in.
// Sends back a -1(failure), -2(validation issue) or the UserId(success) via an OUTPUT parameter.
HttpResponseMessage result1 = await client.GetAsync(restOfUrl);
if (result1.IsSuccessStatusCode)
{
var readTask1 = result1.Content.ReadAsAsync<string>();
readTask1.Wait();
returnedApiValue = Convert.ToInt32(readTask1.Result);
if (returnedApiValue == -2)
{
ViewBag.errormessage = "You entered an invalid user name and/or password";
}
else
{
// I have the 'user id'.
// Do other processing....
}
}
else
{
ModelState.AddModelError(string.Empty, "Server error on signing in. 'validatelogin'. Please contact the administrator.");
}
}
}
}
return View(signInViewModel);
}
catch (Exception)
{
throw;
}
}
It now has a header but still NOT building the URL properly as it is not including the "/api/profileandblog" part.
Here is the web api and the method being called:
namespace GbngWebApi2.Controllers
{
[RoutePrefix("api/profileandblog")]
public class WebApi2Controller : ApiController
{
[HttpGet]
[Route("validatelogin/{userName}/{userPassword}/{ipAddress}/")]
public IHttpActionResult ValidateLogin(string userName, string userPassword, string ipAddress)
{
try
{
IHttpActionResult httpActionResult;
HttpResponseMessage httpResponseMessage;
int returnValue = 0;
// Will either be a valid 'user id" or a -2 indicating a validation issue.
returnValue = dataaccesslayer.ValidateLogin(userName, userPassword, ipAddress);
httpResponseMessage = Request.CreateResponse(HttpStatusCode.OK, returnValue);
httpActionResult = ResponseMessage(httpResponseMessage);
return httpActionResult;
}
catch (Exception)
{
throw;
}
}
}
}
Here's the network tab of the client browser before I hit the button to fire of the Asp.Net MVC method.
The network tab of the client browser after I hit the button to fire of the Asp.Net MVC method and it fails.
Here's another example of Postman executing another method of my api just fine.
I got it to work by setting this as: client.BaseAddress = new Uri("localhost:56224"); and setting the string restOfUrl = "/api/profileandblog/validatesignin/" + signInViewModel.Username + "/" + signInViewModel.Password + "/" + myIpAddress + "/";

passing access token to Jira using OAuth Authentication

I am using OAuth authenication in Jira to test some methods in jira using JIRA Rest Java Client. I have got the access token using OAuth authenication that I need to pass on Jira URL. Here is all what I have got to get access token.
Token is 38ESi9IJW5u3vKDslPFtuV1ZtzDpr6zi
Token secret is cnDSL8oJyuoaQdRcFDwgHzLppSshQn9b
Retrieved request token. go to http://bmh1060149:8080/plugins/servlet/oauth/authorize?oauth_token=38ESi9IJW5u3vKDslPFtuV1ZtzDpr6zi
Access token is : 015CeJiH8cpI5R3OKpNco158kApq8YwV
Now I am passing that access token to Jira URL but I am getting an empty array. Please let me know where I am doing wrong or what changes do I need to incorporate into my code to make this thing work. Here is my code.
public void getAllIssueTypesUsingOAuth(JiraCQCredential jcqcred) {
System.out.println("Inside getAllIssuetypeAssociatedToProject for JiraAdapterImpl");
//String username = jcqcred.getUserName();
//String password = jcqcred.getPassword();
String jiraURL = jcqcred.getJiraUrl();
if (!jiraURL.endsWith("/")) {
jiraURL = jiraURL + "/";
}
try {
String accessToken = JiraAdapterImpl.getAccessToken(); // This method is giving me access token
URL url = new URL(jiraURL + "rest/api/2" + "/" + "issuetype?access_token=" + accessToken);
HttpURLConnection httpConnection = (HttpURLConnection) url.openConnection();
httpConnection.addRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
httpConnection.setRequestProperty("Content-Type", "application/json");
httpConnection.setRequestMethod("GET");
BufferedReader reader = new BufferedReader(new InputStreamReader(httpConnection.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = "";
while ((line = reader.readLine()) != null) {
sb.append(line);
}
String issueTypes = sb.toString();
System.out.println("Issuetype associated to project are\n" + issueTypes);
JSONArray jsonArray = new JSONArray(issueTypes);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String issueNames = (String) jsonObject.get("name");
System.out.println(issueNames);
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
Its giving me an empty array like []
Hi After searching the little bit I finally managed to a find the solution to the above problem. After getting the access token just pass that access token to the makeAuthenticatedRequest(url, accessToken) method that will give you the resultant data which you want to retrive. Here url is the url which you want to hit to get the resultant data.
private AtlassianOAuthClient getJiraOAuthClient() {
final String baseURI = "http://bmh1060149:8080";
final String consumerKey = "hardcoded-consumer";
final String consumerPrivatekey = "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";
AtlassianOAuthClient jiraoAuthClient = new AtlassianOAuthClient(consumerKey, consumerPrivatekey, baseURI, "");

Here is the code to get Access Token
private String getAccessToken() {
AtlassianOAuthClient jiraoAuthClient = getJiraOAuthClient();
TokenSecretVerifierHolder requestToken = jiraoAuthClient.getRequestToken();
String authorizeUrl = jiraoAuthClient.getAuthorizeUrlForToken(requestToken.token);
String token = requestToken.token;
String tokenSecret = requestToken.secret;
System.out.println("Token is " + requestToken.token);
System.out.println("Token secret is " + requestToken.secret);
System.out.println("Retrieved request token. go to " + authorizeUrl);
String accessToken = jiraoAuthClient.swapRequestTokenForAccessToken(token, tokenSecret, "");
System.out.println("Access token is : " + accessToken);
return accessToken;
}
This is the method you call to retrieve the data.
public void getAllCommentOfIssueUsingOAuth() {
logger.info("Inside getAllCommentOfIssue for JiraAdapterImpl");
AtlassianOAuthClient jiraoAuthClient = getJiraOAuthClient();
String accessToken = getAccessToken();
String url = "your Jira URL";
String responseAsString = jiraoAuthClient.makeAuthenticatedRequest(url, accessToken);
System.out.println(responseAsString);
}
This will give you the resultant JSON data or XML data in resultantString.

How to get oauth access token in console without authentication prompt

I want to oauth authentication like

return Redirect(Googleurl);
}
The credentials window (popup) is how you ask the user if you can access their data. There is no way to get access to a users data without asking the user first if you may access their data. That is how Oauth2 works.
If you are accessing your own data then you can use something called a Service account. Service accounts are pre authorized. You can take the service account and grant it access to your google calendar, you could give it access to a folder in Google drive. Then you can authenticate using the service account. Service accounts are like dummy users.
My article about service accounts: Google Developer service account

Remove the "\" from your url

Also make the app-id and and secretlike this
<app-id>:<app_secret>
example kdfjkfjdsakfjd93842908039489:kdjsfkajidsjf8939034820

Linq2Twitter Bad Authentication Data Error 215

I'm getting a LinqToTwitter.TwitterQueryException "Bad Authentication Data" with innerException "The remote server returned an error: (400) Bad Request."
I'm using the latest version of LinqToTwitter (v2.1.06) and Twitter API v1.1.
The following code is used for authentication:
private XAuthAuthorizer GetAuthorizer()
{
var auth = new XAuthAuthorizer
{
Credentials = new XAuthCredentials
{
ConsumerKey = CONSUMER_KEY,
ConsumerSecret = CONSUMER_SECRET,
}
};
auth.Credentials.AccessToken = ACCESS_TOKEN;
auth.Credentials.OAuthToken = OAUTH_TOKEN;
auth.Authorize();
return auth;
}
And the error happens on the line of the foreach loop below:
XAuthAuthorizer _auth = GetAuthorizer();
_twitter = new TwitterContext(_auth);
var friendTweets = from tweet in _twitter.Status where tweet.Type == StatusType.Show && tweet.ID == tweetID select tweet;
foreach (var tweet in friendTweets)
{
AddTweetToCache(tweetID, tweet);
return tweet;
}
Any help would be greatly appreciated!
This fixed it. I was using the authentication method.
var auth = new ApplicationOnlyAuthorizer
{
Credentials = new InMemoryCredentials
{
ConsumerKey = CONSUMER_KEY,
ConsumerSecret = CONSUMER_SECRET
}
};
