Rust Requires Chilkat v11.0.0+

Get the Photos for a User

See more Facebook Examples

Demonstrates how to get the photos that the user has uploaded. 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);

// Indicate that we only want the photos the user has personally uploaded.
let _ = rest.add_query_param("type", "uploaded");

// We could limit the number of photos by setting a limit.
let _ = rest.add_query_param("limit", "5");

// Gets the 1st page of photos. (Not the actual image data, but the information about each photo.)
// See https://developers.facebook.com/docs/graph-api/reference/user/photos/ for more information.
let Ok(response_json) = rest.full_request_no_body("GET", "/v2.7/me/photos") else {
    println!("{}", rest.last_error_text());
    return;
};

let json = chilkat::JsonObject::new();
json.set_emit_compact(false);
let _ = json.load(&response_json);
println!("{}", json.emit().unwrap_or_default());

// A sample JSON response is shown below.  
// This is the code to parse the JSON response.
