Add support for LinkedIn

[abjerner]

I have some code lying around for this, that I need to finish and clean up a bit. This is probably something that will be added after the release of v1.0.

Hi. When are you able to release your v.1.0 of Skybrud with implementation of linkedin authentification support?

[abjerner]

LinkedIn is currently not an area of focus, since I'm working on improving the implementation for the services already supported instead.

I don't really have a time frame for when v1.0 will be released since I primarily work on this project in my spare time. An optimistic guess is that v1.0 will be out in a couple of months, but LinkedIn support is something that will be introduced after this release.

But as I wrote in my previous comment, I do have some unfinished code for LinkedIn. I will try to find some time to wrap this a bit, and push the code to GitHub ;)

@makdff I have now added a new project to the solution called Skybrud.Social.LinkedIn. I have uploaded this due to requests by a few users, but it will not be officially supported until at least after v1.0, meaning that I wont have the time to document or answer questions.

Anyways, this little snippet might help you out with then authentication using OAuth 2.0:

@using Skybrud.Social.LinkedIn.OAuth2

@model MvcApplication1.Models.TestPage

@{
    ViewBag.Title = "Index";
}

@{

    // Handle input
    string action = Request.QueryString["do"];
    string code = Request.QueryString["code"];
    string state = Request.QueryString["state"];

    // Initialize the OAuth client
    LinkedInOAuthClient oauth = new LinkedInOAuthClient {
        ApiKey = "",
        ApiSecret = "",
        RedirectUri = Model.BaseUrl
    };

    if (action == "login") {

        // Redirect the user to the authentication page at LinkedIn.com
        Response.Redirect(oauth.GetAuthorizationUrl("bacon", "r_basicprofile"));

    } else if (!String.IsNullOrWhiteSpace(code)) {

        LinkedInAccessTokenResponse token = oauth.GetAccessTokenFromAuthCode(code);
        oauth.AccessToken = token.AccessToken;

        DateTime expiresAt = DateTime.Now.AddSeconds(token.ExpiresIn.TotalSeconds);

        <table>
            <tr>
                <td style="font-size: 10px; font-weight: bold; text-transform: uppercase; padding-right: 25px;">Expires in</td>
                <td style="font-size: 12px;">
                    @token.ExpiresIn.TotalSeconds
                    (~@token.ExpiresIn.TotalDays days &bull; @expiresAt.ToString("r"))
                </td>
            </tr>
            <tr>
                <td style="font-size: 10px; font-weight: bold; text-transform: uppercase; padding-right: 25px;">Access Token</td>
                <td style="font-size: 12px;">
                    @token.AccessToken
                </td>
            </tr>
        </table>

        <br />

        <a href="@Model.BaseUrl?do=login" class="button">Login again</a>

    } else if (Request.QueryString["error"] != null) {

        <p><b>@Request.QueryString["error"]</b><br />@Request.QueryString["error_description"]</p>

        <a href="@Model.BaseUrl?do=login" class="button">Login with LinkedIn</a>

    } else {

        <a href="@Model.BaseUrl?do=login" class="button">Login with LinkedIn</a>

    }

}

@abjerner Great thanks :)

I haven't really updated any of the code, but the LinkedIn implementation now has it's own repository, so you can follow the progress here:

https://github.com/abjerner/Skybrud.Social.LinkedIn

Eventually the LinkedIn project will also be released as it's own NuGet package, although I don't really have a time frame for this.
