java.net.SocketTimeoutException: 超时

Question

使用 OkHttp 库，应用程序面临以下 SocketTimeoutException 问题。如果请求大小较小，则它工作正常（小于 1MB）。我在 10 秒内收到此异常，甚至我的套接字超时 ( readTimeout ) 值要高得多。请求一直失败（大小为 1.8MB）。当我使用 HttpUrlConnection 执行请求时，它工作正常。失败的可能原因是什么？

Answer 1

对于 OkHttp 3，OkHttp 的默认值为 10 秒。您可以将超时增加到 30 秒。

 OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS); // connect timeout
client.setReadTimeout(30, TimeUnit.SECONDS);    // socket timeout
