Rust Requires Chilkat v11.0.0+

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. Rust

// 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
let oauth2 = chilkat::OAuth2::new();
oauth2.set_access_token("FACEBOOK-ACCESS-TOKEN");

let rest = chilkat::Rest::new();

// Connect to Facebook...
if rest.connect("graph.facebook.com", 443, true, true).is_err() {
    println!("{}", rest.last_error_text());
    return;
}

// Provide the authentication credentials (i.e. the access key)
let _ = rest.set_auth_o_auth2(&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.

let post_id = "10224048320139890_10210156138515282".to_string();

let sb_path = chilkat::StringBuilder::new();
let _ = sb_path.append("/v2.7/");
let _ = sb_path.append(&post_id);

// Select the fields we want.
// This example will select almost all the possible fields.
// See https://developers.facebook.com/docs/graph-api/reference/post/
let _ = rest.add_query_param("fields", "id,message,created_time,caption,description,from,link,name,object_id,picture,place,privacy,properties,shares,source,status_type,story,targeting,to,type,updated_time,with_tags");

let Ok(response_json) = rest.full_request_no_body("GET", &sb_path.get_as_string().unwrap_or_default()) else {
    println!("{}", rest.last_error_text());
    return;
};
