JarCastingdropwizard-api-key-bundle
A Dropwizard bundle that provides a simple way to manage API keys for callers of your service.
[
Getting Started
Just add this maven dependency to get started:
<dependency>
<groupId>io.dropwizard-bundles</groupId>
<artifactId>dropwizard-api-key-bundle</artifactId>
<version>0.8.4-1</version>
</dependency>
Add the bundle to your environment:
public class MyApplication extends Application<MyConfiguration> {
@Override
public void initialize(Bootstrap<MyConfiguration> bootstrap) {
bootstrap.addBundle(new ApiKeyBundle<>());
}
@Override
public void run(MyConfiguration cfg, Environment env) throws Exception {
// ...
}
}
You will also need to make your MyConfiguration class implement ApiKeyBundleConfiguration in order to provide the bundle with the necessary information it needs to know your API keys.
public class MyConfiguration implements ApiKeyBundleConfiguration {
@Valid
@NotNull
@JsonProperty("authentication")
private final ApiKeyConfiguration apiKeyConfiguration = null;
/**
* Return the API key configuration.
*/
@Override
public ApiKeyConfiguration getApiKeyConfiguration() {
return apiKeyConfiguration;
}
Now you can use API key based authentication in your application by declaring a method on a resource that has an @Auth annotated String parameter. See the Dropwizard Authentication documentation for more details. The passed in parameter value will be the name of the application that made the request if the authentication process was successful.
As far as configuration goes you can define your API keys in your application's config file. Assuming, like in the above example, you called your API key configuration element authentication then you can use a config file like this:
authentication:
basic-http:
cache-spec: maximumSize=1000, expireAfterAccess=10m
realm: MyApplication
keys:
application-1: api-key-1
application-2: api-key-2
