In Java 11, the HttpClient API provides a flexible way to handle HTTP requests and responses. When dealing with errors and exceptions, there are several strategies and patterns you can use to ensure your application can handle unexpected issues effectively while making HTTP calls. 1. Exception Types in Java 11 HttpClient Here are some common […]
Chaining asynchronous calls using Java 11’s HttpClient and CompletableFuture can be achieved by leveraging the reactive capabilities of CompletableFuture. The sendAsync method of HttpClient supports asynchronous processing, and you can chain multiple calls together using methods like thenApply, thenCompose, or thenAccept. Here’s a step-by-step example: Key Concepts Used: CompletableFuture: Allows for async processing and chaining […]
In Java 11, the HttpClient API provides a modern and user-friendly way to send both synchronous and asynchronous HTTP requests. To send asynchronous requests, you’ll use the sendAsync method, which returns a CompletableFuture. Here’s how to use it: Step-by-Step Guide to Sending Asynchronous Requests: Initialize the HttpClient: Use HttpClient to create an instance. This is […]
To create a reusable HttpClient instance in Java 11, you should utilize the HttpClient class introduced in Java 11. This class is designed to handle HTTP requests and responses, and when properly configured, it is optimized for reuse throughout your application. Here’s how: Key Concepts: Thread Safety: HttpClient is immutable and thread-safe. You can create […]
In Java 11, the HttpClient API does not provide an explicit “cancel” method for ongoing HTTP requests, but you can use a java.util.concurrent.Future to achieve cancellation. When you send an asynchronous request using HttpClient in Java 11, the sendAsync method returns a CompletableFuture. You can call cancel on the CompletableFuture to attempt to cancel the […]
Handling GZIP or compressed responses using the Java 11 HttpClient is straightforward. The HttpClient automatically supports GZIP compression, but you need to specify the Accept-Encoding header in the request to indicate that you accept compressed responses, and it will handle decompression automatically if the server responds with compressed data. Here’s how you can do it: […]
