Get Linked In profile details using LinkedIn OAuth2.0 API

Hi,

Today I want to share about how to get linkedin profile details into in your application(asp.net app) using linkedin OAuth2.0 API.

Here I will create one simple asp.net application and I will show how to get LinkedIn profile and display in a page.

I. Register an application on LinkedIn

To get LinkedIn profile details we need to generate/create one profile in https://developers.linkedin.com. once you create the profile it will generate one id and one secret key.
Using these two keys in your application we can get the users profile details

Here the steps to create profile and generate keys

1. Go to " https://developer.linkedin.com" then click on " My Apps" on top navigation.

2. Once you go to My Apps page its looks like as below and click on "Add new application"

3. Now enter all required information. we are creating this application in development environment so we use localhost and we use one static port number. when you are creating profile for production environment then give host url here.

4. Once you successfully created your profile, it automatically generate API Key and Secret Key

Now we will create development web application in asp.net and try to get user's profile details.

II.  Get an access token -

Here I want to give a overview on how the application works.

OAuth2 basically allows third party application, to access protected resource of a specific user. You may have seen some web applications/sites allows you to login through your Google, Facebook, LinkedIn etc accounts. As an example just try this with any mentioned account (Google, Facebook, Yahoo etc.). After giving your username password credentials you will be notified the authorities which the third party application will get if you agreed to proceed.

First we need to authenticate the application with API Key and Secret Key.

Once it is authenticated, likedin API will ask for user credentials.

If user enter correct username and password it will generate code and that code will sent back to the redirect URL.

Using the code in application will request the access token with HTTP POST request method.

if the code is validate/verified, it will generate/returns access token key with expire time.

With this access token key we can get user profile details by passing access key token in the http header request with HTTP GET request method.

The access token represent the credentials to access protected resources. So your application does not need to store resource owner's credentials, but the access token.

Here the steps to create application to get user profile details

1. Create one asp.net application using Visual Studio 2012 named it as "GetLinkedInUserProfileDetails".

2. Make sure that application run on the port number which you have given while creating profile in developer site.

3. Now we need to add LinkedIn profile API Key and Secret Key by using one class file call it as "LinkedinAuthDetails" and the class looks like as below.

4. Now design your master page and add login.aspx with one button as shown below.

when user clicked on the button, it will go to LinkedIn for application authorization.
Here the code in button click event.

 Response.Redirect("https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=" + obj.apiKey + "&scope=r_fullprofile&state=DCEEFWF45453sdffef424&redirect_uri=" + HttpUtility.HtmlEncode(obj.redirectUrl));

If the query string have correct API Key, and website URL then it will ask for user credentials.

If not it will throw an error and out put will be like this.


Once the credentials are validated then it will redirect to "RedirectUrl" which is the query string along with the code value. This code value is used to get access token for the loggedin user profile.

After successful user credential validation it is redirected to "ProfileDetails" page with code value in query string.

5. In ProfileDetails page, we have code value with this code value we will try to get access token key by using http web request with POST method.

 dynamic responseText = obj.VerifyAuthentication(Request.QueryString["code"]);

This is the method to get access key token. 

Here the method definition.

III. Make API calls - Yes, after obtaining access token you are free to call API methods with that, until it expires.

Now we will make HTTP web request to LinkedIn API for user profile details with GET method.

                        string authcode = "";
                        dynamic dynobj = JsonConvert.DeserializeObject(responseText);
                        foreach (var item in dynobj)
                        {
                            if (item.Name == "access_token")
                            {
                                authcode = "Bearer " + item.Value; break;
                            }
                        }
                        response = GetProfileResponse(authcode);

Here the GetProfileResponse method definition.

If  the HTTP request header has valid access token then it will give response with user profile details.

There the application output.

SharePoint 2013 Document Library Drag and Drop option not showing in IE

One of new feature in SharePoint 2013 is the ability to drag and drop files into document libraries. This is useful for adding multiple documents to a library and removes the need to open the library in explorer view.


The reason for drag and drop not working and your document library looking like the above screen shot is due to two reasons:
1. You are using Internet Explorer 9 or lower.
2. You don’t have any Office 2013 components installed.

Resolution:

1. This is due to the fact that the drag and drop functionality uses HTML5. Installing Office 2013 will add an ActiveX control to allow you to use this drag and drop functionality in older browsers.
2. If you were to upgrade to IE10 or IE11 the HTML5 would be handled and the drag and drop would be available regardless of whether or not Office 2013 is installed.

ISSUE: Save site as template option missing for publishing sites in SharePoint 2013.

Problem: When you browse to  SharePoint Server Site settings page, you discover that the Save site as template option isn't available.

This issue most frequently occurs because the Community Sites or the SharePoint Server Publishing feature is currently enabled or was previously enabled for the affected site. 

SharePoint doesn’t support creating a template from a site where publishing or community features were enabled. This is because the publishing feature creates site elements that are not supported as part of a template, and these elements remain even when the feature is disabled. This also includes templates that were created through SharePoint Designer.

Even when i tried to navigate to “_layouts/savetmpl.aspx”("Save site as template" page), it is throwing following error.

The "Save site as template" action is not supported on this site.

Here the solution:
After searching on net and i came to know that for publishing site "SaveSiteAsTemplate" is disabled.

Now how to enable this option.

Below are the steps to resolve this issue.

1. Open you Team Site in SharePoint Designer 2013.

2. In SharePoint Designer, under Sites tab select "Site Options".

3. Find "SaveSiteAsTemplateEnabled" in Site Properties.

4. Next change this setting to "true".

5. Now in your Publishing site navigate to "http://<site name>/_layouts/15/savetmpl.aspx" and you would see the old Save Site as Template Page as expected.

How to change ownership or email of SharePoint access request

The access request feature allows people to request access to content that they do not currently have permission to see. As a site owner, you can configure the feature to send you mail when someone requests access to a site. You can then choose whether to approve or decline their request. If you approve the request, you can also specify the specific level of permission you’d like to assign to a user.

The access request feature also works together with the Share command for sites. If someone who is not a site owner for a site (that is, someone who does not have full control for a site) uses the Share command to invite other people to view a site, then that action will generate an access request for the site owner. The site owner can then approve or decline the request, or specify the permission level to be assigned to the new user.

ISSUE:

we can set up access request on your site, by default who creates the site that person is responsible for approving access requests and all request will be send to the same person.
Now, that person moved away from the current department or you may want to change the person.

Resolution:

Site owners can set up the access request feature so that it sends them an email when someone requests access to a site.

    1. Go to Settings Settings button > Site Settings.

    2. Under Users and Permissions, click Site Permissions.

    3. On the Permissions tab, click Access Request Settings.

    In the Access Request Settings dialog box, select the check box next to Allow access requests, and then type the email address of the person you want to make responsible for approving access requests.

    4. Click OK.

If you want to disable access request you can uncheck "Allow access requests".
