Facebook exposes a Graph API that lets developers access data in the Facebook ecosystem. To protect the privacy of their users, not all data accessible via Facebook.com will be accessible via the Graph API - eg. getting the friends list of a user.
Most methods in the Graph API require an access token. Access tokens are what identifies you as a user, or if you access the API on behalf of your application. If you don't already have an access token, the page about authentication will help you out.
The Graph API has multiple versions. What version of the API that you're using may affect how you should use Skybrud.Social - eg. co control which fields that are returned by the API.
Although it can be a bit comprehensive, I can also recommend reading at least parts of the Graph API documentation.
It's also worth mentioning that the Facebook examples throughout this site are based on the Skybrud.Social.Facebook package. Most of the implementation is the same for the older Skybrud.Social package, but there are some differences.
To install the package via NuGet, either use the .NET CLI:
dotnet add package Skybrud.Social.Facebook --version 1.0.0-beta006
or the NuGet Package Manager:
Install-Package Skybrud.Social.Facebook -Version 1.0.0-beta006
While the Facebook API has a somewhat flat URL structure, the implementation in Skybrud.Social is divided into an endpoint for each type of data. You can see a list of these endpoints below:
Similar to the other services supported in Skybrud.Social, there is a FacebookOAuthClient class for handling the authentication as well as the raw communication with the API. If you already have a valid access token, you can get your posts similar to this:
// Initialize an instance of FacebookOAuthClient from a specified access token
FacebookOAuthClient client = new FacebookOAuthClient(accessToken);
// Get posts for "me"
IHttpResponse response = client.Posts.GetPosts("me");
// Get the raw response body
string responseBody = response.Body;
Since you're probably not interested in working with the raw JSON, the FacebookService class builds on top of FacebookOAuthClient to give an object-oriented approach so you don't have to worry about parsing. The FacebookService class can be used similar to this:
// Initialize an instance of FacebookService from a specified access token
FacebookService service = FacebookService.CreateFromAccessToken(accessToken);
// Get posts for "me"
FacebookPostsResponse response = service.Posts.GetPosts("me");
// Iterate through the posts
foreach (FacebookPost post in response.Body.Data) {
// Do something with the post
}
