This article explains how to combine Kotlin coroutines, Flow, Retrofit, and OkHttp to create a clean, reactive, and maintainable network request framework for Android applications, covering concepts, core principles, and practical code examples.
This article introduces four Java HTTP client libraries—Java HttpClient, Apache HttpComponents, OkHttp, and Spring WebClient—explains their key features, provides async GET and sync POST code examples for each, and offers guidance on selecting the right client for Spring Boot and plain Java projects.
This article reviews ten practical methods for invoking third-party HTTP services in Spring Boot 3.3, covering plain JDK URL, HttpClient, Apache HttpClient, OkHttp, RestTemplate, WebClient, RestClient, Http Interface, OpenFeign, and Gateway proxy, each with code samples and key advantages.
This article explains why and how to replace OpenFeign with native Spring HttpInterface alternatives such as Apache HttpClient, OkHttp, and RestTemplate, covering security motivations, configuration details, code examples, and practical recommendations for microservice remote calls.
This article introduces mica-http, a lightweight Fluent‑style HTTP client built on OkHttp, walks through dependency setup, synchronous and asynchronous usage, global logging, custom client and cookie management, presents performance benchmarks, and highlights its automatic resource handling for safe, high‑performance requests.
This article introduces multiple Java approaches for sending HTTP GET and POST requests, covering the built‑in HttpURLConnection class, Apache HttpClient, Square's OkHttp, and Spring's RestTemplate, with step‑by‑step explanations and complete code examples for each method.
This article provides a comprehensive analysis of OkHttp’s source code, explaining its request‑execution flow, layered architecture, interceptor chain design, and demonstrates how to implement custom interceptors for unified request handling in Java and Android projects.
By dissecting OkHttp’s source, the article explains its layered architecture, the interceptor‑chain implementation of the Chain‑of‑Responsibility pattern, and shows how developers can add custom interceptors—such as authentication headers—to uniformly handle requests, retries, caching, and network I/O in Java and Android.
This article introduces OKHttpUtil, a concise Java wrapper for the OkHttp library, outlines its key features, provides Maven dependency instructions, demonstrates GET, POST, file upload, download, and chained request usage, and shows how to integrate and configure it in Spring Boot as well as quickly build external API clients such as eBay.
This article details how an Android team unified multiple network libraries into OkHttp, integrated HttpDns to bypass carrier DNS hijacking, migrated to HTTPS and HTTP/2, and applied a series of performance and security optimizations that markedly improved request speed, reliability, and user experience across diverse mobile network conditions.
This article introduces OKHttpUtil, a lightweight wrapper for OkHttp that simplifies HTTP GET, POST, file upload/download, and chainable requests in Java, provides Maven integration, Spring Boot configuration, and demonstrates how to encapsulate external APIs such as eBay with concise code examples.
This article introduces AndroidMonitor, a lightweight Android packet‑capture library, explains how to add its monitor and monitor‑plugin dependencies, configure ProGuard, customize entry names, ports and logos, and optionally use AndroidLocalService to expose captured data via a local socket for both mobile and PC UI visualization.
This article explains how to replace OpenFeign's default HTTP client with OkHttp, configure request and response interceptors, and customize OkHttpClientBuilder in Spring Cloud, providing detailed code examples and configuration steps for effective interceptor implementation.
This article explains multiple approaches for invoking third‑party HTTP APIs in Java, covering JDK HttpURLConnection, Apache HttpClient, CloseableHttpClient, SpringBoot RestTemplate, and OkHttp, with detailed code examples, configuration steps, and usage patterns for GET and POST requests.
This article provides a comprehensive overview of OkHttp, covering its overall request process, the role of the dispatcher, how application and network interceptors work, TCP connection reuse via the connection pool, idle‑connection cleanup, key advantages, and the design patterns employed in the framework.
This article explains the fundamentals of TCP/UDP and HTTP, details OkHttp's interceptor chain and caching mechanisms, and demonstrates a generic offline‑upload solution using Kotlin reflection to persist and replay network calls when connectivity is restored.
The article presents a non‑intrusive Android framework that preloads page network requests in parallel with page initialization, describing its three‑part architecture, routing and network interceptors, code implementation, and performance gains that can reduce overall page load time by up to 100 ms.
This article details the redesign of Snowball's Android network framework using OkHttp and Retrofit, covering motivations, architectural layers, solutions for domain switching, custom annotations, data validation, migration strategy, and the resulting performance and maintainability improvements.
This article compares Apache HttpClient and OkHttp for Java backend development, explaining how to create clients, configure timeouts, perform GET/POST/PUT/DELETE requests, upload files, cancel requests, and presents performance test results with code examples for each library.
This article details a real‑world Android file‑upload failure caused by the Android Studio Profiler’s OkHttp3Interceptor closing the request’s BufferedSink, explains the debugging steps taken, and provides code modifications to the ProgressRequestBody to prevent the IllegalStateException and ensure correct upload progress tracking.
