Getting information about an application
If you need to get information about a given Facebook application (app), you can use the GetApplication
method in the applications endpoint. In it's simplest form, you can use the method like shown below:
@using Skybrud.Social.Facebook.Models.Applications
@using Skybrud.Social.Facebook.Responses.Applications
@inherits WebViewPage<Skybrud.Social.Facebook.FacebookService>
@{
FacebookGetApplicationResponse response = Model.Applications.GetApplication("145634995501895");
FacebookApplication application = response.Body;
<pre>ID: @application.Id</pre>
<pre>Name: @application.Name</pre>
}
In this example, 145634995501895
is the ID of Facebook's own Graph API Explorer app.
Fields to be returned by the API
Like other responses from the Facebook Graph API, a response with information about an application will only contain a few fields by default. For an application, this will be the id
, name
, link
and category
fields (or the Id
, Name
, Link
and Category
properties when mapped in Skybrud.Social).
To request specific fields from the API, you can specify an instance of FacebookFieldsCollection
as the second parameter for the GetApplication
method:
@using Skybrud.Social.Facebook.Constants
@using Skybrud.Social.Facebook.Fields
@using Skybrud.Social.Facebook.Models.Applications
@using Skybrud.Social.Facebook.Responses.Applications
@inherits WebViewPage<Skybrud.Social.Facebook.FacebookService>
@{
FacebookFieldsCollection fields = new FacebookFieldsCollection {
FacebookApplicationFields.Id,
FacebookApplicationFields.AppName,
FacebookApplicationFields.Description,
FacebookApplicationFields.Namespace
};
FacebookGetApplicationResponse response = Model.Applications.GetApplication("198111253569705", fields);
FacebookApplication application = response.Body;
<pre>ID: @application.Id</pre>
<pre>Name: @application.Name</pre>
<pre>App name: @application.AppName</pre>
<pre>Description: @application.Description</pre>
<pre>Namespace: @application.Namespace</pre>
}
There are a number of different ways to initialize an instance of FacebookFieldsCollection
, so try have a look at the fields page for more information. Like shown above, the FacebookApplicationFields
class also provides constants for known fields/properties of an application.
