(Java) Firebase DELETE - Removing DataUses the DELETE method to delete data. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:
import com.chilkatsoft.*; public class ChilkatExample { static { try { System.loadLibrary("chilkat"); } catch (UnsatisfiedLinkError e) { System.err.println("Native code library failed to load.\n" + e); System.exit(1); } } public static void main(String argv[]) { // 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. CkFileAccess fac = new CkFileAccess(); String accessToken = fac.readEntireTextFile("qa_data/tokens/firebaseToken.txt","utf-8"); if (fac.get_LastMethodSuccess() != true) { System.out.println(fac.lastErrorText()); return; } CkRest rest = new CkRest(); // 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. boolean success = rest.Connect("chilkat.firebaseio.com",443,true,true); if (success != true) { System.out.println(rest.lastErrorText()); return; } CkAuthGoogle authGoogle = new CkAuthGoogle(); authGoogle.put_AccessToken(accessToken); rest.SetAuthGoogle(authGoogle); // 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" String jsonResponse = rest.fullRequestNoBody("DELETE","/pig-rescue/animal/-KI3pT33wKauiMxY4QTB.json"); if (rest.get_LastMethodSuccess() != true) { // 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.) System.out.println(rest.lastErrorText()); return; } // Check the response status code. A 200 response status indicates success. if (rest.get_ResponseStatusCode() != 200) { System.out.println(rest.responseStatusText()); System.out.println(jsonResponse); System.out.println("Failed."); return; } System.out.println("Success."); } } |
