Request Interceptor for Apache Client that signs the request for AWS.
Originally created to support AWS' Elasticsearch Service using the Jest client.
You have to add the AWSSigningRequestInterceptor to the end of the Apache client request chain. Otherwise it won't have visibility of all of the headers being added to the request.
final AWSSigner awsSigner = new AWSSigner(awsKey, awsSecret, REGION, SERVICE, clock);
builder.addInterceptorLast(new AWSSigningRequestInterceptor(awsSigner));To be able to add the AWSSigningRequestInterceptor to Jest, and thus be able to sign requests to the Elasticsearch Service, you need to override the configureHttpClient method in the JestClientFactory.
final JestClientFactory factory = new JestClientFactory() {
@Override
protected HttpClientBuilder configureHttpClient(HttpClientBuilder builder) {
builder.addInterceptorLast(new AWSSigningRequestInterceptor(awsSigner));
return builder;
}
@Override
protected HttpAsyncClientBuilder configureHttpClient(HttpAsyncClientBuilder builder) {
builder.addInterceptorLast(new AWSSigningRequestInterceptor(awsSigner));
return builder;
}

- Allow different credential providers (maybe. it's quite nice not having to depend on an AWS SDK)
