Read a Single Facebook Post

See more Facebook Examples

Demonstrates how to read the contents of a single Facebook post. A post is an individual entry in a profile's feed. The profile could be a user, page, app, or group. Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // This example assumes a previously obtained an access token
    oauth2 := chilkat.NewOAuth2()
    oauth2.SetAccessToken("FACEBOOK-ACCESS-TOKEN")

    rest := chilkat.NewRest()

    // Connect to Facebook...
    success = rest.Connect("graph.facebook.com",443,true,true)
    if success == false {
        fmt.Println(rest.LastErrorText())
        oauth2.DisposeOAuth2()
        rest.DisposeRest()
        return
    }

    // Provide the authentication credentials (i.e. the access key)
    rest.SetAuthOAuth2(oauth2)

    // This example assumes a post id was already retrieved.
    // For example, it could've been retrieved by reading the user's feed:
    // See Parsing the Facebook User Feed for code showing how to parse the JSON feed content.
