+ + public WalletAddressService(HttpClient httpClient) { + this.httpClient = httpClient; + } + + public CompletableFuture get(String url) { + var request = HttpRequest.builder() + .method(HttpMethod.GET) + .uri(url) + .header("Accept", "application/json") + .build(); + + return httpClient.execute(request) + .thenApply(this::parseWalletAddress); + } +} +``` + +SDK users configure the HTTP client through `OpenPaymentsClient.builder()`: + +```java +var client = OpenPaymentsClient.builder() + .walletAddress("https://wallet.example.com/alice") + .privateKey(privateKey) + .keyId(keyId) + // HTTP configuration options available here + .connectTimeout(Duration.ofSeconds(10)) + .maxRetries(5) + .build(); +``` + +## Best Practices + +### 1. Reuse HttpClient Instances +HTTP clients are thread-safe and maintain connection pools. Create once, use everywhere: + +```java +// Good - single instance +public class Services { + private static final HttpClient HTTP_CLIENT = HttpClientBuilder.simple("https://api.example.com"); + + public static HttpClient getHttpClient() { + return HTTP_CLIENT; + } +} + +// Avoid - creating new instances repeatedly +public void makeRequest() { + HttpClient client = HttpClientBuilder.simple("https://api.example.com"); // Don't do this! + // ... +} +``` + +### 2. Use Appropriate Timeouts +Balance responsiveness with reliability: + +```java +// Production - generous timeouts +.connectTimeout(Duration.ofSeconds(10)) +.requestTimeout(Duration.ofSeconds(30)) +.socketTimeout(Duration.ofSeconds(30)) + +// Development - faster feedback +.connectTimeout(Duration.ofSeconds(5)) +.requestTimeout(Duration.ofSeconds(10)) +``` + +### 3. Enable Resilience in Production +Use retries and circuit breakers, but consider disabling in development: + +```java +boolean isProduction = "production".equals(System.getenv("ENV")); + +HttpClient client = HttpClientBuilder.create() + .baseUrl(apiUrl) + .resilienceEnabled(isProduction) + .maxRetries(isProduction ? 5 : 0) + .build(); +``` + +### 4. Use Jitter with Retries +Prevents thundering herd effects: + +```java +// Good - with jitter +.retryStrategy(RetryStrategy.exponentialBackoff(Duration.ofMillis(100)) + .withFullJitter()) + +// Avoid - without jitter (can cause thundering herd) +.retryStrategy(RetryStrategy.exponentialBackoff(Duration.ofMillis(100))) +``` + +### 5. Monitor Circuit Breaker State +Set up alerts when circuits open in production: + +```java +client.addResponseInterceptor(response -> { + if (response.statusCode() >= 500) { + metrics.increment("circuit_breaker.failures"); + } + return response; +}); +``` + +### 6. Close Clients When Done +Release resources properly: + +```java +try (HttpClient client = HttpClientBuilder.simple("https://api.example.com")) { + // Use client + var response = client.execute(request).join(); +} // Automatically closed +``` + +### 7. Use Virtual Threads Effectively +Let the client handle concurrency: + +```java +// Good - concurrent execution with virtual threads +List> futures = urls.stream() + .map(url -> HttpRequest.builder().method(HttpMethod.GET).uri(url).build()) + .map(client::execute) + .toList(); + +CompletableFuture.allOf(futures.toArray(new CompletableFuture[0])).join(); +``` + +### 8.

+ * This factory provides advanced capabilities beyond the basic {@link HttpClientBuilder}: + *

  • Named instances: Create and retrieve clients by name
    • + *
  • Instance caching: Reuse client instances across application
    • + *
  • Environment-specific configuration: Different configs for dev/staging/prod
    • + *
  • Service-specific clients: Different implementations for different services
    • + *
+ * + *

Usage Patterns

+ * + *

1. Single Global Instance

+ * + * 
{@code
+ * // Create once at application startup
+ * HttpClient client = HttpClientFactory.createDefault("https://api.example.com");
+ *
+ * // Reuse throughout application
+ * HttpClient sameClient = HttpClientFactory.getDefault();
+ * }
+ * + *

2. Multiple Named Instances

+ * + * 
{@code
+ * // Create different clients for different services
+ * HttpClientFactory.register("payment-service", HttpClientBuilder.create().baseUrl("https://payments.example.com")
+ *         .implementation(HttpClientImplementation.APACHE).maxRetries(5).build());
+ *
+ * HttpClientFactory.register("user-service", HttpClientBuilder.create().baseUrl("https://users.example.com")
+ *         .implementation(HttpClientImplementation.OKHTTP).maxRetries(3).build());
+ *
+ * // Retrieve by name
+ * HttpClient paymentClient = HttpClientFactory.get("payment-service");
+ * HttpClient userClient = HttpClientFactory.get("user-service");
+ * }
+ * + *

3. Environment-Specific Configuration

+ * + * 
{@code
+ * // Configure based on environment
+ * Environment env = Environment.fromSystemProperty();
+ * HttpClient client = HttpClientFactory.forEnvironment(env);
+ * }
+ * + *

4. Service-Specific Optimizations

+ * + * 
{@code
+ * // Fast internal service (minimal retry, OkHttp)
+ * HttpClient internal = HttpClientFactory.forInternalService("internal-api.example.com");
+ *
+ * // External unreliable API (aggressive retry, Apache)
+ * HttpClient external = HttpClientFactory.forExternalService("external-api.example.com");
+ * }

Usage Examples

+ * + *

Basic Usage

+ * + * 
{@code
+ * import zm.hashcode.openpayments.http.factory.HttpClientBuilder;
+ * import zm.hashcode.openpayments.http.core.*;
+ *
+ * // Create a simple client
+ * HttpClient client = HttpClientBuilder.simple("https://api.example.com");
+ *
+ * // Make a request
+ * var request = HttpRequest.builder()
+ *     .method(HttpMethod.GET)
+ *     .uri("/users/123")
+ *     .header("Accept", "application/json")
+ *     .build();
+ *
+ * // Execute
+ * HttpResponse response = client.execute(request).join();
+ * }
+ * + *

Advanced Configuration

+ * + * 
{@code
+ * import zm.hashcode.openpayments.http.factory.HttpClientBuilder;
+ * import zm.hashcode.openpayments.http.config.HttpClientImplementation;
+ * import zm.hashcode.openpayments.http.resilience.RetryStrategy;
+ *
+ * HttpClient client = HttpClientBuilder.create()
+ *     .baseUrl("https://api.example.com")
+ *     .implementation(HttpClientImplementation.APACHE)
+ *     .connectTimeout(Duration.ofSeconds(10))
+ *     .requestTimeout(Duration.ofSeconds(30))
+ *     .maxRetries(3)
+ *     .retryStrategy(RetryStrategy.exponentialBackoff(Duration.ofMillis(100)))
+ *     .circuitBreakerEnabled(true)
+ *     .build();
+ * }
+ * + *

Multiple Implementations

+ * + * 
{@code
+ * import zm.hashcode.openpayments.http.factory.*;
+ * import zm.hashcode.openpayments.http.config.HttpClientImplementation;
+ *
+ * // Fast internal service - OkHttp
+ * HttpClient internal = HttpClientBuilder.create()
+ *     .baseUrl("http://internal-api:8080")
+ *     .implementation(HttpClientImplementation.OKHTTP)
+ *     .maxRetries(1)
+ *     .build();
+ *
+ * // Slow external service - Apache with aggressive retries
+ * HttpClient external = HttpClientBuilder.create()
+ *     .baseUrl("https://external-api.com")
+ *     .implementation(HttpClientImplementation.APACHE)
+ *     .maxRetries(5)
+ *     .build();
+ * }
+ * + *

Factory Pattern

+ * + * 
{@code
+ * import zm.hashcode.openpayments.http.factory.HttpClientFactory;
+ *
+ * // Register named clients
+ * HttpClientFactory.register("payment",
+ *     HttpClientBuilder.create()
+ *         .baseUrl("https://payments.api.com")
+ *         .implementation(HttpClientImplementation.APACHE)
+ *         .maxRetries(5)
+ *         .build());
+ *
+ * // Retrieve by name
+ * HttpClient paymentClient = HttpClientFactory.get("payment");
+ * }
+ * + *

Design Principles

+ * + *

1. Package by Feature

+ *

+ * Classes are organized by their role/feature rather than by technical layer. This makes it easier to understand the + * module's structure and find related classes. + * + *

2. Clear Dependencies

+ *

+ * Dependency direction: core ← config ← resilience ← impl ← factory + * + *

3. Abstraction

+ *

+ * The {@code core} package contains pure abstractions with no implementation dependencies, making it easy to swap + * implementations. + * + *

4. Separation of Concerns

+ *

+ * Each package has a single, well-defined responsibility: + *

    + *
  • core - Defines contracts
    • + *
  • config - Configuration and settings
    • + *
  • resilience - Retry and circuit breaker logic
    • + *
  • interceptor - Request/response interception
    • + *
  • impl - Concrete HTTP client implementations
    • + *
  • factory - Object creation and configuration
    • + *
+ * + *

5. Decorator Pattern

+ *

+ * The {@code ResilientHttpClient} in the resilience package wraps any {@code HttpClient} implementation to add + * resilience features, keeping concerns separated. + * + *

Thread Safety

+ * This decorator wraps any {@link HttpClient} implementation and provides: + *

    + *
  • Automatic retries: Configurable retry attempts with backoff strategies
    • + *
  • Circuit breaker: Prevents cascading failures by failing fast when service is down
    • + *
  • Configurable retry conditions: Retry based on status codes or exceptions
    • + *
+ * + *

+ * The circuit breaker has three states: + *

    + *
  • CLOSED: Normal operation, requests pass through
    • + *
  • OPEN: Too many failures detected, requests fail immediately
    • + *
  • HALF_OPEN: Testing if service has recovered with limited requests
    • + *
+ * + *

+ * This implementation uses virtual threads (Java 21+) for efficient retry delays without blocking platform threads. + * + *

+ * Example usage: + * + *

+ * This package provides comprehensive support for Open Payments authentication including: + *

    + *
  • GNAP Protocol - Grant Negotiation and Authorization Protocol (RFC 9635)
    • + *
  • HTTP Signatures - Message signature authentication (RFC 9421)
    • + *
  • Token Management - Access token rotation and revocation

  • Cryptographic Keys - Ed25519 key generation and management
    • + *
+ * + *

Key Components

+ * + *

Grant Management ({@link zm.hashcode.openpayments.auth.grant})

+ *

+ * Implements the GNAP protocol for obtaining access tokens: + * + * 

{@code
+ * GrantService grantService = new GrantService(httpClient, signatureService, objectMapper);
+ *
+ * // Request a grant
+ * GrantRequest request = GrantRequest.builder()
+ *         .accessToken(AccessTokenRequest.builder().access(Access.incomingPayment(List.of("create", "read"))).build())
+ *         .client(Client.builder().key(clientKey.jwk()).build()).build();
+ *
+ * GrantResponse response = grantService.requestGrant(authServerUrl, request).join();
+ * }
+ * + *

HTTP Signatures ({@link zm.hashcode.openpayments.auth.signature})

+ *

+ * Automatic request signing with Ed25519: + * + * 

{@code
+ * ClientKey clientKey = ClientKeyGenerator.generate("my-key-id");
+ * HttpSignatureService signatureService = new HttpSignatureService(clientKey);
+ *
+ * // Sign a request
+ * HttpRequest signedRequest = signatureService.signRequest(request);
+ * }
+ * + *

Token Management ({@link zm.hashcode.openpayments.auth.token})

+ *

+ * Manage access token lifecycle: + * + * 

{@code
+ * TokenManager tokenManager = new TokenManager(httpClient, objectMapper);
+ *
+ * // Rotate token before expiration
+ * AccessTokenResponse newToken = tokenManager.rotateToken(currentToken).join();
+ *
+ * // Revoke token when done
+ * tokenManager.revokeToken(token).join();
+ * }
+ * + *

Security Considerations

+ * + *
    + *
  • Private keys must be stored securely (e.g., hardware security module, encrypted keystore)
    • + *
  • Access tokens should be rotated regularly before expiration
    • + *
  • Always revoke tokens when they are no longer needed
    • + *
  • Use HTTPS for all Open Payments API communication
    • + *
  • Validate all responses to detect tampering or replay attacks

+ * This package provides interceptor implementations for cross-cutting concerns in HTTP communication: + *

    + *
  • Logging - Request and response logging with configurable verbosity
    • + *
  • Authentication - Automatic authentication header injection
    • + *
  • Error Handling - Structured error extraction and logging
    • + *
+ * + *

Interceptor Types

+ * + *

Request Interceptors

+ *

+ * Process and modify outgoing HTTP requests: + * + *

    + *
  • {@link zm.hashcode.openpayments.http.interceptor.LoggingRequestInterceptor} - Logs requests with sensitive header + * masking
    • + *
  • {@link zm.hashcode.openpayments.http.interceptor.AuthenticationInterceptor} - Adds authentication headers
    • + *
+ * + *

Response Interceptors

+ *

+ * Process incoming HTTP responses: + * + *

    + *
  • {@link zm.hashcode.openpayments.http.interceptor.LoggingResponseInterceptor} - Logs responses with different + * levels for success/error
    • + *
  • {@link zm.hashcode.openpayments.http.interceptor.ErrorHandlingInterceptor} - Extracts structured error + * information
    • + *
+ * + *

Usage Examples

+ * + *

Adding Logging

+ * + * 
{@code
+ * HttpClient client = new ApacheHttpClient(config);
+ *
+ * // Add request logging
+ * client.addRequestInterceptor(new LoggingRequestInterceptor());
+ *
+ * // Add response logging with custom configuration
+ * client.addResponseInterceptor(new LoggingResponseInterceptor(Level.FINE, // Log successful responses at FINE level
+ *         Level.SEVERE, // Log errors at SEVERE level
+ *         true, // Include headers
+ *         false // Don't include body
+ * ));
+ * }
+ * + *

Adding Authentication

+ * + * 
{@code
+ * // Bearer token authentication (OAuth 2.0, JWT)
+ * client.addRequestInterceptor(AuthenticationInterceptor.bearer("my-access-token"));
+ *
+ * // GNAP token authentication (Open Payments)
+ * client.addRequestInterceptor(AuthenticationInterceptor.gnap("gnap-token"));
+ *
+ * // Basic authentication
+ * client.addRequestInterceptor(AuthenticationInterceptor.basic("dXNlcjpwYXNz"));
+ *
+ * // Custom authentication scheme
+ * client.addRequestInterceptor(AuthenticationInterceptor.custom("ApiKey", "sk_live_123"));
+ * }
+ * + *

Adding Error Handling

+ * + * 
{@code
+ * ObjectMapper objectMapper = new ObjectMapper();
+ * client.addResponseInterceptor(new ErrorHandlingInterceptor(objectMapper));
+ *
+ * // Errors are automatically logged and structured information is extracted
+ * // from JSON error responses
+ * }
+ * + *

Combining Multiple Interceptors

+ * + * 
{@code
+ * HttpClient client = new ApacheHttpClient(config);
+ *
+ * // Interceptors execute in the order they are added
+ * client.addRequestInterceptor(new LoggingRequestInterceptor());
+ * client.addRequestInterceptor(AuthenticationInterceptor.bearer(token));
+ *
+ * client.addResponseInterceptor(new ErrorHandlingInterceptor(objectMapper));
+ * client.addResponseInterceptor(new LoggingResponseInterceptor());
+ * }
+ * + *

Custom Interceptors

+ * + *

+ * You can create custom interceptors by implementing the functional interfaces: + * + * 

{@code
+ * // Custom request interceptor
+ * RequestInterceptor customRequest = request -> {
+ *     // Modify request (e.g., add headers, modify URL)
+ *     Map newHeaders = new HashMap<>(request.headers());
+ *     newHeaders.put("X-Custom-Header", "value");
+ *
+ *     return HttpRequest.builder().method(request.method()).uri(request.uri()).headers(newHeaders)
+ *             .body(request.getBody().orElse(null)).build();
+ * };
+ *
+ * // Custom response interceptor
+ * ResponseInterceptor customResponse = response -> {
+ *     // Process response (e.g., extract metrics, cache)
+ *     if (response.statusCode() == 429) {
+ *         // Handle rate limiting
+ *     }
+ *     return response;
+ * };
+ * }
+ * + *

Security Considerations

+ * + *
    + *
  • Logging interceptors automatically mask sensitive headers (Authorization, tokens, keys)
    • + *
  • Be cautious when logging request/response bodies - they may contain sensitive data
    • + *
  • Consider log levels carefully in production (use FINE/DEBUG for verbose logging)
    • + *
  • Authentication interceptors handle credentials - ensure secure storage
