in ASP.NET MVC app I'm trying to use LinkedIn for user Authentication and get the user's full profile.
I'm usin OpenAuth (DotNetOpenAuth and Microsoft.AspNet.Membership.OpenAuth)
Request for User Data
private const string UserInfoEndpoint = "https://api.linkedin.com/v1/people/~" + Fields;
var uri = BuildUri(UserInfoEndpoint, new NameValueCollection { { "oauth2_access_token", accessToken } });
var webRequest = (HttpWebRequest)WebRequest.Create(uri);
using (var webResponse = webRequest.GetResponse())
using (var stream = webResponse.GetResponseStream())
{
if (stream == null)
return null;
using (var textReader = new StreamReader(stream))
{
var xml = textReader.ReadToEnd();
var extraData = XElement.Parse(xml)
.Elements()
.ToDictionary(
el => el.Name.LocalName,
el => el.Value
);
extraData.Add("accesstoken", accessToken);
return extraData;
}
}
This making a successful get of user basic data. but when I change the url like below then it returning 403 Forbidden
private const string UserInfoEndpoint = "https://api.linkedin.com/v2/people/~" + Fields;
or
private const string UserInfoEndpoint = "https://api.linkedin.com/v2/me/?";
I noticed about partnership program, Is that what I need to access these url's? or what is really wrong here?
This docs about the v2 API but nothing about partnership program
if you are using V1 ( till 1st march ) then this is valid :
https://api.linkedin.com/v1/people/~
This url is related to r_basicprofile
if you are moving to V2 then you can't use this url because in V2 you have to take permission from linked to use r_basicprofile
in V2 you can use : r_liteprofile for firstName,lastName,profilePicture,id
r_emailaddress for getting emailAddress

We are trying to implement Twitter new DM API from Salesforce. We are sending our the JSON request in the body as mentioned in documentation but the legacy method for Oauth authorization is not working. Any help is greatly appreciated.
To add, I am sending a DM from salesforce to twitter, So
1) I am setting the request body in JSON.
2) I am doing a POST.
3) I am hitting the endpoint at 'https://api.twitter.com/1.1/direct_messages/events/new.json'
4) Oauth2, getting the access token(successfully)
5) Setting header as ('Content-Type', 'application/json').
6) Creating Authorization header as twitter mentions using consumer key, Nonce, Signature, Signature method, Timestamp, Version. Building the same as in "Guide" section of developer.twitter.com/en/docs/basics/authentication/guides/
7) On running the error code "{"errors":[{"code":32,"message":"Could not authenticate you."}]}".
Another important information that I had been using twitter old API to send DM that works perfect, only difference is it sends the request body in URL parameters instead of JSOn body but the authorization method remains same. As some new Functionality can only be achieved via Twitter New API and according to documentation the body needs to be sent via JSON format. Therefore the request part is changed but authorization is same.
Sample code:-
String accTok = 'redacted';
String conKey = 'redacted';
String conSec = 'redacted';
String accTokSec = 'redacted';
String theTweet = 'Hello world!';
String screenName ='some_test_username';
String jsonString = TwitterJsonReqGenerator.generateJSON(theTweet, screenName);
system.debug('JSON string ='+jsonString);
httpRequest newReq = new httpRequest();
newReq.setBody(jsonString);
newReq.setMethod('POST');
newReq.setEndpoint('https://api.twitter.com/1.1/direct_messages/events/new.json');
//Generate Nonce
string oAuth_nonce = EncodingUtil.base64Encode(blob.valueOf(string.valueOf(Crypto.getRandomInteger()+system.now().getTime())+string.valueOf(Crypto.getRandomInteger()))).replaceAll('[^a-z^A-Z^0-9]','');
map<String, String> heads = new map<String, String>{
'oauth_token'=>accTok,
'oauth_version'=>'1.0',
'oauth_nonce'=>oAuth_nonce,
'oauth_consumer_key'=>conKey,
'oauth_signature_method'=>'HMAC-SHA1',
'oauth_timestamp'=>string.valueOf(system.now().getTime()/1000)
};
//Alphabetize
string[] paramHeads = new string[]{};
paramHeads.addAll(heads.keySet());
paramHeads.sort();
string params = '';
for(String encodedKey : paramHeads){
params+=encodedKey+'%3D'+heads.get(encodedKey)+'%26';
}
//params+='status'+percentEncode('='+percentEncode(theTweet));
params+=percentEncode(theTweet);
//Build the base string
string sigBaseString = newReq.getMethod().toUpperCase()+'&'+EncodingUtil.urlEncode(newReq.getEndpoint(),'UTF-8')+'&'+params;
system.debug('signatureBaseString == '+sigBaseString);
//calculate signature
string sigKey = EncodingUtil.urlEncode(conSec,'UTF-8')+'&'+EncodingUtil.urlEncode(accTokSec,'UTF-8');
blob mac = crypto.generateMac('hmacSHA1', blob.valueOf(sigBaseString), blob.valueOf(sigKey));
string oauth_signature = EncodingUtil.base64Encode(mac);
heads.put(EncodingUtil.urlEncode('oauth_signature','UTF-8'), EncodingUtil.urlEncode(oauth_signature,'UTF-8'));
//build the authorization header
paramHeads.clear();
paramHeads.addAll(heads.keySet());
paramHeads.sort();
string oAuth_Body = 'OAuth ';
for(String key : paramHeads){
oAuth_Body += key+'="'+heads.get(key)+'", ';
}
oAuth_Body = oAuth_Body.subString(0, (oAuth_Body.length() - 2));
newReq.setHeader('Authorization', oAuth_Body);
system.debug('Authroization Header == '+oAuth_Body);
newReq.setHeader('Content-Type', 'application/json');
httpResponse httpRes = new http().send(newReq);
String response = httpRes.getBody();
system.debug(response);

I've written Twitter libraries and applications in the past, and the bst advice that I can give you is to use an existing implementation of OAuth instead of attempting to write your own. Re-implementing OAuth in new code is re-inventing the wheel, and it's a wheel that hates you. There are a number of robust and mature OAuth libraries that are free and/or open source.
Just happened to stumble on your query. I am posting a code(C#) (though it is a bit late) which worked for me to send DM to Twitter using the new API. Hope this helps. Thanks to Danny Tuppeny's blog

The tutorial for OneDrive for Business (here: https://dev.onedrive.com/auth/aad_oauth.htm)
However, I don't want the user to have to login as I'm building a web API - I want the app to login. So, I have followed the tutorial for service to service authentication (here: https://msdn.microsoft.com/en-us/library/azure/dn645543.aspx) which gets me an access token.
However, when I try to authenticate with the service I get an error saying "unsupported app only token". The code I'm using is below (btw, I'm using RestSharp):
public string GetAccessToken()
{
var client = new RestClient("https://login.microsoftonline.com/<tenant>/oauth2");
var request = new RestRequest("token", Method.POST);
request.AddParameter("grant_type", "client_credentials");
request.AddParameter("client_id", <client_id>);
request.AddParameter("client_secret", <client_secert);
request.AddParameter("resource", "https://<tenant>-my.sharepoint.com/");
var response = client.Execute(request);
var content = response.Content;
var authModel = JsonConvert.DeserializeObject<AuthResponseModel>(content);
return authModel.AccessToken;
}
this gets me the access token
This is how I try to access my drive:
public string GetDrive()
{
var accessToken = GetAccessToken();
var client = new RestClient("https://<tenant>-my.sharepoint.com/_api/v2.0/");
var request = new RestRequest("drive", Method.GET);
request.AddHeader("Authorization: Bearer", accessToken);
var response = client.Execute(request);
var content = response.Content;
return content;
}
Does anyone have any tips? This is getting slightly maddening.
I'm trying to get an ASP.NET MVC site to accept Salesforce as an authentication provider, but I am not having any luck. I'll start out with the IAuthenticationClient I have so far:

private const String TokenEndpoint = BaseEndpoint + #"/services/oauth2/token";
private const String RevokeEndpoint = BaseEndpoint + #"/services/oauth2/revoke";
public SalesForceOAuth2Client(String consumerKey, String consumerSecret)
: base("SalesForce")
{
if (String.IsNullOrWhiteSpace(consumerKey))
{
throw new ArgumentNullException("consumerKey");
}
if (String.IsNullOrWhiteSpace(consumerSecret))
{
throw new ArgumentNullException("consumerSecret");
}
this.consumerKey = consumerKey;
this.consumerSecret = consumerSecret;

var builder = new UriBuilder(AuthorizeEndpoint);
builder.Query = "response_type=code"

}

protected override String QueryAccessToken(Uri returnUrl, String authorizationCode)

using (StreamWriter streamWriter = new StreamWriter(webRequest.GetRequestStream()))

streamWriter.Write("&code=" + HttpUtility.UrlEncode(authorizationCode));
streamWriter.Flush();
}
HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();
if (webResponse.StatusCode == HttpStatusCode.OK)
{
using (StreamReader streamReader = new StreamReader(webResponse.GetResponseStream()))
{
String response = streamReader.ReadToEnd();
var queryString = HttpUtility.ParseQueryString(response);
return queryString["access_token"];
}
}
return String.Empty;
}
}
The primary problem is that redirect_uri != Callback Url.
Salesforce enforces the callback URL you supply in the application configuration to match exactly to the value provided in redirect_uri of QueryAccessToken. Unfortunately OAuthWebSecurity relies on DotNetOpenAuth.AspNet, and that library appends two query parameters: __provider__ and __sid__. If I try to remove those (see the hack in GetServiceLoginUrl), obviously the login fails because the hand-back doesn't know how to continue on with the request without knowing which provider to use.
To work around this I did notice that the request call accepts an optional state parameter which is (essentially) there for passing things back and forth across the request/callback. However, with the dependence on __provider__ and __sid__ being their own keys having data=__provider__%3DSalesForce%26__sid__%3D1234567890 is useless.
Is there a work-around without having to fork/recompile the Microsoft.Web.WebPages.OAuth library and modify the OAuthWebSecurity.VerifyAuthenticationCore(HttpContextBase, String) method to look at data first, then continue on to OpenAuthSecurityMananer.GetProviderName?
Also, in case the registration mattered (AuthConfig.cs):
OAuthWebSecurity.RegisterClient(
new SalesForceOAuth2Client(/*consumerKey*/, /*consumerSecret*/),
"SalesForce",
new Dictionary<String, Object>()
);
Update (11.01.2013)
I just got a response back from Salesforce. It looks like they don't know how to implement 3.1.2 of the RFC which means that any query parameters you send in with the return_uri are not only ignored, but prohibited (at least when dynamic in nature). So, it looks like I can't use a library that works on every other platform and follows the standard--i have to create my own.
Sigh.
I have tweet poster in my application which uses oAuth 1.0 which will retire soon and will be non functional. I have to upgrade my API to 1.1. Twitter development center says that, If oAuth is used by your application, you can easily transaction to 1.1 by only updating your API endpoint. What exactly is API endpoint?
Here I'm having hard understanding about API endpoint. I think my asyncronous post call URL must be upgraded.
Here is the relevant codes which I think that might include the answer;
private void btnPostTweet_Click(object sender, RoutedEventArgs e)
{
namebocx.Text = userScreenName;
if (txtBoxNewTweet.Text.Trim().Length == 0) { return; }
var credentials = new OAuthCredentials
{
Type = OAuthType.ProtectedResource,
SignatureMethod = OAuthSignatureMethod.HmacSha1,
ParameterHandling = OAuthParameterHandling.HttpAuthorizationHeader,
ConsumerKey = TwitterSettings.consumerKey,
ConsumerSecret = TwitterSettings.consumerKeySecret,
Token = this.accessToken,
TokenSecret = this.accessTokenSecret,
Version = "1.0"
};
var restClient = new RestClient
{
Authority = TwitterSettings.StatusUpdateUrl,
HasElevatedPermissions = true,
Credentials = credentials,
Method = WebMethod.Post
};
restClient.AddHeader("Content-Type", "application/x-www-form-urlencoded");
// Create a Rest Request and fire it
var restRequest = new RestRequest
{
Path = "1/statuses/update.xml?status=" + txtBoxNewTweet.Text //Here must be endpoint of Api??
};
var ByteData = Encoding.UTF8.GetBytes(txtBoxNewTweet.Text);
restRequest.AddPostContent(ByteData);
restClient.BeginRequest(restRequest, new RestCallback(PostTweetRequestCallback));
}
}
and also here is the authentication settings:
public class TwitterSettings
{
public static string RequestTokenUri = "https://api.twitter.com/oauth/request_token";
public static string AuthorizeUri = "https://api.twitter.com/oauth/authorize";
public static string AccessTokenUri = "https://api.twitter.com/oauth/access_token";
public static string CallbackUri = "http://www.google.com";
public static string StatusUpdateUrl { get { return "http://api.twitter.com"; } }
public static string consumerKey = "myconsumerkeyhere";
public static string consumerKeySecret = "myconsumersecrethere";
public static string oAuthVersion = "1.0a";
}
Here what twitter says me to replace with this instead of written in my code;
https://api.twitter.com/1.1/statuses/update.json
and some parameters told here -->> https://dev.twitter.com/docs/api/1.1/post/statuses/update
How should I update my API endpoint, what kind of changes do I have to do?
If you can help me, I really appreciate
You can change this:
Path = "1/statuses/update.xml?status=" + txtBoxNewTweet.Text
//Here must be endpoint of Api??
to this:
Path = "1.1/statuses/update.json?status=" + txtBoxNewTweet.Text
//Here must be endpoint of Api??
