(.NET Core C#) Firebase PUT - Writing Data

Demonstrates how to PUT new data to a Firebase JSON database. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

Chilkat for Mono

// Demonstrates how to PUT new data to a Firebase JSON database.

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

Chilkat.AuthGoogle authGoogle = new Chilkat.AuthGoogle();
authGoogle.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..

// Generate a new push ID.
Chilkat.Prng prng = new Chilkat.Prng();
string pushId = prng.FirebasePushId();

// We're going to add a new pig with just the name.
Chilkat.JsonObject pigRecord = new Chilkat.JsonObject();
pigRecord.AppendString("name","William");

Chilkat.StringBuilder path = new Chilkat.StringBuilder();
path.Append("/pig-rescue/animal/");
path.Append(pushId);
path.Append(".json");

// The string content of the last arg passed is  {"name":"William"} 
string jsonResponse = rest.FullRequestString("PUT",path.GetAsString(),pigRecord.Emit());
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.
if (rest.ResponseStatusCode != 200) {
    Debug.WriteLine(rest.ResponseStatusText);
    Debug.WriteLine(jsonResponse);
    Debug.WriteLine("Failed.");
    return;
}

Debug.WriteLine(jsonResponse);
Debug.WriteLine("Success.");

// Note: In many of the Chilkat examples, you may notice strange ways
// of doing something that should be simpler and shorter.  For example,
// building the path (above) could've been written differently,
// with some simple string concatenation.
// 
// The reason is that the Chilkat examples are written in a 
// proprietary "example code" scripting language,
// and then automatically generated to each of the different programming
// languages you see on example-code.com.  The code generation is
// limited in what it can do.  For example, string concatentation
// is not yet a feature of the "example code" scripting language (as of May 2016), 
// and therefore you won't see the use of a programming language's string
// concatentation operators in any example.
