Retrofit 源码解析：一款基于 OkHttp 的网络请求库

阅读更多关于 Retrofit 源码解析：一款基于 OkHttp 的网络请求库

Retrofit 可以说和 OkHttp 是亲兄弟了，它们都是由 Square 公司推出的网络请求库，并且 Retrofit 实际上是基于 OkHttp 实现的，它在 OkHttp 现有功能的基础上进行了封装，支持通过注解进行网络请求参数的配置，同时对数据返回后的解析、序列化进行了统一的包装，甚至在近期引入了对协程对支持。今天就让我们一起来看看 Retrofit 是如何在 OkHttp 这样一个已经固定的框架的基础上，优雅的进行封装并拓展功能的。本篇源码解析基于 Retrofit v2.7.0 个人博客： https://blog.N0tExpectErr0r.cn 小专栏： https://xiaozhuanlan.com/N0tExpectErr0r 基本使用我们首先来看看 Retrofit 的基本使用，来对它有个大致的了解。首先，我们可以构建一个如下的请求 Service 类，它里面对各个请求的方法及参数通过注解进行了标注： public interface GitHubService { @GET ( "users/{user}/repos" ) Call < List < Repo > > listRepos ( @Path ( "user" ) String user ) ; } 之后，我们可以构建一个 Retrofit 对象，并通过 Retrofit
