What is SwiftApi?

SwiftApi is an Apache Thrift based API for CraftBukkit Minecraft servers. This API allows simple calls to Bukkit methods over the internet using your favorite programming language. This plugin acts as the server component, allowing you to write client programs/websites/apps that can talk to your CraftBukkit server in almost any programming language!

SwiftApi 2.0

SwiftApi-2.0-alpha is now available for download together with SwiftApiVault-1.0-alpha. Check out the wiki for more information.

What can you do with it?

Basically, SwiftApi allows you write awesome code and apps that can talk to and control your Minecraft server.

An example of such an app is MineCenter. Check it out at http://minecenter.org

Configuration Options

Edit the plugins/SwiftApi/config.yml file to your liking.

The most important options are:

# Authentication Information (CHANGE THESE)
username: admin
password: password
salt: saltines

Leaving these at default would make it easy for an attacker to use this API on your server.

Creating a Client App

Once you have downloaded the Apache Thrift compiler, you can create a client app in a few lines of code.

Check out the example PHP project here: https://github.com/phybros/swiftapi-example-php

Try the C#.NET/VB.NET tutorial here: http://dev.bukkit.org/server-mods/swiftapi/pages/examples/c-net-vb-net/

Generate the Client Library

You can generate the client library (example is in C#) by typing

thrift -r --gen csharp SwiftApi.thrift

The -r option tells the compiler to generate code for all files (including ones that are referenced in SwiftApi.thrift with the include directive. The gen csharp option tells the compiler to generate C# code. This command will leave you with a gen-csharp directory with all the code you need to connect to a server running the SwiftApi plugin.

Include the Code in your App

If you're using C#, you can just drag all the source files right into your client app to use them, or alternatively you could create a new project with the generated files to keep your code and the generated code seperate.


Visit the Examples page for examples of how to use the code.

Here's an example in C#:

//open a connection to a server running SwiftApi
TSocket socket = new TSocket("your.bukkitserver.org", 21111);

//create a new SwiftApi client object
TBinaryProtocol protocol = new TBinaryProtocol(new TFramedTransport(socket));
SwiftApi.Client client = new SwiftApi.Client(protocol);

//get the server version and output it
Console.WriteLine("Server Version: " + client.getServerVersion(authString));

//close the connection

Because the code is based on Apache thrift, you have access to many of the complex types in the CraftBukkit API, such as the Player object.

This example is in C#, but the thrift compiler is able to create libraries for almost ANY programming language.
