Firebase DELETE - Removing Data

See more Firebase Examples

Uses the DELETE method to delete data. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

Rust

// Uses the DELETE method to delete a Firebase record.

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

// This example assumes a JWT authentication token, if required, has been previously obtained.
// See Get Firebase Access Token from JSON Service Account Private Key for sample code.

// Load the previously obtained Firebase access token into a string.
let fac = chilkat::FileAccess::new();
let Ok(access_token) = fac.read_entire_text_file("qa_data/tokens/firebaseToken.txt", "utf-8") else {
    println!("{}", fac.last_error_text());
    return;
};

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

// Make the initial connection (without sending a request yet).
// Once connected, any number of requests may be sent.  It is not necessary to explicitly
// call Connect before each request.  
if rest.connect("chilkat.firebaseio.com", 443, true, true).is_err() {
    println!("{}", rest.last_error_text());
    return;
}

let auth_google = chilkat::AuthGoogle::new();
auth_google.set_access_token(&access_token);
let _ = rest.set_auth_google(&auth_google);

// Chilkat's sample data (pig-rescue data) is publicly readable at: https://chilkat.firebaseio.com/.json
// This data is publicly readable, but not writable.  You'll need to 
// run against your own database..

// We're going to delete a pig we previously added.  The push ID of that pig was -KI3pT33wKauiMxY4QTB,
// so the path will be "/pig-rescue/animal/-KI3pT33wKauiMxY4QTB.json"

let Ok(json_response) = rest.full_request_no_body("DELETE", "/pig-rescue/animal/-KI3pT33wKauiMxY4QTB.json") else {
    // Something happened in the communications (either no request was sent, or no response was received.
    // (The Chilkat REST API also has lower-level methods where an app can send the request in one call,
    // and then receive the response in another call.)
    println!("{}", rest.last_error_text());
    return;
};

// Check the response status code.   A 200 response status indicates success.
if rest.response_status_code() != 200 {
    println!("{}", rest.response_status_text());
    println!("{}", json_response);
    println!("Failed.");
    return;
}

println!("Success.");
