Blizzard WoW REST API Client Generator

Generator of Java REST Client SDK on top of Blizzard`s World of Warcraft API endpoints described here.

Overview

Blizzard has a series of APIs publicly available. The detailed list can be found on Blizzard`s official website.

This project aims to automatically generate Java SDK Clients to consume the APIs Blizzard is making available, based on OpenAPI specification files, in conjuction with the openapi-generator.

Build with

• Maven
• Java 8

Getting started

Application Register

Register a new application with Blizzard from here. You will be provided with a Client ID and Client Secret.

App Bootstrapping

Run mvn clean install to build everything - all registered APIs, and a very basic sample.

After this, there are 2 ways to run the sample from driver-app .

1. set BLIZZARD_API_CLIENT_ID, BLIZZARD_API_CLIENT_SECRET with the values obtained from registering the application in driver-app/pom.xml :

   <build>
       <plugins>
           <plugin>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-maven-plugin</artifactId>
               <version>2.2.6.RELEASE</version>
               ...
               <configuration>
                   <environmentVariables>
                       <BLIZZARD_API_CLIENT_ID><!-- Client from application regsiter --></BLIZZARD_API_CLIENT_ID>
                       <BLIZZARD_API_CLIENT_SECRET><!--Secret from application register--></BLIZZARD_API_CLIENT_SECRET>
                   </environmentVariables>
               </configuration>
           </plugin>
       </plugins>
   </build>
   

   then run mvn spring-boot:run from driver-app .
2. set BLIZZARD_API_CLIENT_ID, BLIZZARD_API_CLIENT_SECRET as environment variables. Then just run java -jar blizzard-sdk-driver-app-1.0-SNAPSHOT.jar

Swagger-ui Integration

In tools/swagger-ui-integration there is a Swagger-UI based project that can be used to visually interact with the exposed APIs in a simple/clean manner. It just renders registered Open API Specification files.

Run it with java -jar tools\swagger-ui-integration\target\blizzard-swagger-ui-integration-1.0-SNAPSHOT.jar --spring.config.location=<path\to\custom\application.yml> for SSL Settings, or disable SSL with --server.ssl.enabled=false

It can also be started with Spring-Boot plugin: mvn spring-boot:run -Dspring-boot.run.arguments="--spring.config.location=<path/to/custom>/application.yml"

Contributing

Adding new modules is straight-forward. You can use the provided Maven Archetype (com.gspatace:blizzard-rest-client-generator) in order to generate new modules. In <root>/client-apis, run mvn archetype:generate -DarchetypeGroupId=com.gspatace -DarchetypeArtifactId=blizzard-rest-client-generator . Sample:

[INFO] Archetype repository not defined. Using the one from [com.gspatace:blizzard-rest-client-generator:1.0-SNAPSHOT] found in catalog local

[INFO] Project created from Archetype in dir: <root>\client-apis\blizzard-wow-character-client

This creates the <artifactId> module, and adds it to the main parent. The OpenAPI description of the target REST API has to be placed in <root>\client-apis\<artifactId>\src\main\resources\<provided-input-spec-file>. mvn clean install will now generate the artifact.

After a new API module is created, it should be added also in parent module.

For Swagger-UI integration, a new endpoint controller should be added in tools/swagger-ui-integration, in com.gspatace.blizzard.swagger.integration.apis package. See Auction House API for reference.
