Question

I’m using the Hammock library and C# to get the basic profile and email address of user from linked in following post here .

I’ve also followed these posts here and here

However for the life of me I cannot get the email address of the linkedin user.

Reading this linkedin post I got new created a new application to get new keys however still no luck.

Went through this linkedin post but could not get it to work either

I’m posting the code below but it’s heavily lifted form the links I followed

var credentials = new OAuthCredentials
            {

                CallbackUrl = "http://localhost:2715/Callback.aspx",

                ConsumerKey = "my consumer key",//not shown

                ConsumerSecret = "my consumer secret",//not shown

                Type = OAuthType.RequestToken,

            };


        var client = new RestClient
            {
                Authority = "https://api.linkedin.com/uas/oauth",
                Credentials = credentials
            };

        //var scope = HttpUtility.UrlEncode("r_basicprofile r_emailaddress");

        var request = new RestRequest
                        {
                            Path = "requestToken?scope=r_basicprofile+r_emailaddress",
                        };

I get this screen when user navigates to linkedin.

To actually request the email I use this code below

 var request = new RestRequest { Path = "people/~/email-address" };

        var credentials = new Hammock.Authentication.OAuth.OAuthCredentials

        {

            Type = OAuthType.AccessToken,

            SignatureMethod = OAuthSignatureMethod.HmacSha1,

            ParameterHandling = OAuthParameterHandling.HttpAuthorizationHeader,

            ConsumerKey = "my consumer key", //not shown

            ConsumerSecret = "my consumer secret", //not shown

            Token = Session["AccessToken"].ToString(),

            TokenSecret = Session["AccessSecretToken"].ToString(),

            Verifier = Session["Verifier"].ToString()

        };


        var client = new RestClient()
        {
            Authority = "http://api.linkedin.com/v1/",
            Credentials = credentials,
            Method = WebMethod.Get
        };


        var MyInfo = client.Request(request);

        String content = MyInfo.Content;

This is the error I get on MyInfo.Content

Thanks in advance for your help.

On trying Kamyar’s suggestion I get the following error message. What else should I try?

Answer 1

I have found solution. Simply, do not include ?scope=r_emailaddres (or other permissions) to .Path property of RestRequest.
Use something like this:

Dim request = New RestRequest With {.Path = "requestToken"}
request.AddParameter("scope", "r_emailaddress")

(vb net syntax)

.AddParameter method is the key.
