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:

C#

bool success = false;

//  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.
Chilkat.FileAccess fac = new Chilkat.FileAccess();
string accessToken = fac.ReadEntireTextFile("qa_data/tokens/firebaseToken.txt","utf-8");
if (fac.LastMethodSuccess != true) {
    Debug.WriteLine(fac.LastErrorText);
    return;
}

Chilkat.Rest rest = new Chilkat.Rest();

//  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.  
success = rest.Connect("chilkat.firebaseio.com",443,true,true);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

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.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.)
    Debug.WriteLine(rest.LastErrorText);
    return;
}

//  Check the response status code.   A 200 response status indicates success.
